What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Learn about our Editorial Process

Literature reviews are a necessary step in a research process and often required when writing your research proposal . They involve gathering, analyzing, and evaluating existing knowledge about a topic in order to find gaps in the literature where future studies will be needed.

Ideally, once you have completed your literature review, you will be able to identify how your research project can build upon and extend existing knowledge in your area of study.

Generally, for my undergraduate research students, I recommend a narrative review, where themes can be generated in order for the students to develop sufficient understanding of the topic so they can build upon the themes using unique methods or novel research questions.

If you’re in the process of writing a literature review, I have developed a literature review template for you to use – it’s a huge time-saver and walks you through how to write a literature review step-by-step:

Literature Review Examples

For the following types of literature review, I present an explanation and overview of the type, followed by links to some real-life literature reviews on the topics.

1. Narrative Review Examples

Also known as a traditional literature review, the narrative review provides a broad overview of the studies done on a particular topic.

It often includes both qualitative and quantitative studies and may cover a wide range of years.

The narrative review’s purpose is to identify commonalities, gaps, and contradictions in the literature .

I recommend to my students that they should gather their studies together, take notes on each study, then try to group them by themes that form the basis for the review (see my step-by-step instructions at the end of the article).

Example Study

Title: Communication in healthcare: a narrative review of the literature and practical recommendations

Citation: Vermeir, P., Vandijck, D., Degroote, S., Peleman, R., Verhaeghe, R., Mortier, E., … & Vogelaers, D. (2015). Communication in healthcare: a narrative review of the literature and practical recommendations. International journal of clinical practice , 69 (11), 1257-1267.

Source: https://onlinelibrary.wiley.com/doi/pdf/10.1111/ijcp.12686  

Overview: This narrative review analyzed themes emerging from 69 articles about communication in healthcare contexts. Five key themes were found in the literature: poor communication can lead to various negative outcomes, discontinuity of care, compromise of patient safety, patient dissatisfaction, and inefficient use of resources. After presenting the key themes, the authors recommend that practitioners need to approach healthcare communication in a more structured way, such as by ensuring there is a clear understanding of who is in charge of ensuring effective communication in clinical settings.

• A Narrative Review of School-Based Physical Activity for Enhancing Cognition and Learning (Mavilidi et al., 2018) – read here
• A narrative review on burnout experienced by medical students and residents (Dyrbye & Shanafelt, 2015) – read here

2. Systematic Review Examples

This type of literature review is more structured and rigorous than a narrative review. It involves a detailed and comprehensive plan and search strategy derived from a set of specified research questions.

The key way you’d know a systematic review compared to a narrative review is in the methodology: the systematic review will likely have a very clear criteria for how the studies were collected, and clear explanations of exclusion/inclusion criteria. 

The goal is to gather the maximum amount of valid literature on the topic, filter out invalid or low-quality reviews, and minimize bias. Ideally, this will provide more reliable findings, leading to higher-quality conclusions and recommendations for further research.

You may note from the examples below that the ‘method’ sections in systematic reviews tend to be much more explicit, often noting rigid inclusion/exclusion criteria and exact keywords used in searches.

Title: The importance of food naturalness for consumers: Results of a systematic review  

Citation: Roman, S., Sánchez-Siles, L. M., & Siegrist, M. (2017). The importance of food naturalness for consumers: Results of a systematic review. Trends in food science & technology , 67 , 44-57.

Source: https://www.sciencedirect.com/science/article/pii/S092422441730122X  

Overview: This systematic review included 72 studies of food naturalness to explore trends in the literature about its importance for consumers. Keywords used in the data search included: food, naturalness, natural content, and natural ingredients. Studies were included if they examined consumers’ preference for food naturalness and contained empirical data. The authors found that the literature lacks clarity about how naturalness is defined and measured, but also found that food consumption is significantly influenced by perceived naturalness of goods.

3. Meta-analysis

This is a type of systematic review that uses statistical methods to combine and summarize the results of several studies.

Due to its robust methodology, a meta-analysis is often considered the ‘gold standard’ of secondary research , as it provides a more precise estimate of a treatment effect than any individual study contributing to the pooled analysis.

Furthermore, by aggregating data from a range of studies, a meta-analysis can identify patterns, disagreements, or other interesting relationships that may have been hidden in individual studies.

This helps to enhance the generalizability of findings, making the conclusions drawn from a meta-analysis particularly powerful and informative for policy and practice.

Title: Cholesterol and Alzheimer’s Disease Risk: A Meta-Meta-Analysis

Citation: Sáiz-Vazquez, O., Puente-Martínez, A., Ubillos-Landa, S., Pacheco-Bonrostro, J., & Santabárbara, J. (2020). Cholesterol and Alzheimer’s disease risk: a meta-meta-analysis. Brain sciences, 10(6), 386.

Source: https://doi.org/10.3390/brainsci10060386  

O verview: This study examines the relationship between cholesterol and Alzheimer’s disease (AD). Researchers conducted a systematic search of meta-analyses and reviewed several databases, collecting 100 primary studies and five meta-analyses to analyze the connection between cholesterol and Alzheimer’s disease. They find that the literature compellingly demonstrates that low-density lipoprotein cholesterol (LDL-C) levels significantly influence the development of Alzheimer’s disease.

Other Types of Reviews

• Scoping Review: This type of review is used to map the key concepts underpinning a research area and the main sources and types of evidence available. It can be undertaken as stand-alone projects in their own right, or as a precursor to a systematic review.
• Rapid Review: This type of review accelerates the systematic review process in order to produce information in a timely manner. This is achieved by simplifying or omitting stages of the systematic review process.
• Integrative Review: This review method is more inclusive than others, allowing for the simultaneous inclusion of experimental and non-experimental research. The goal is to more comprehensively understand a particular phenomenon.
• Critical Review: This is similar to a narrative review but requires a robust understanding of both the subject and the existing literature. In a critical review, the reviewer not only summarizes the existing literature, but also evaluates its strengths and weaknesses. This is common in the social sciences and humanities .
• State-of-the-Art Review: This considers the current level of advancement in a field or topic and makes recommendations for future research directions. This type of review is common in technological and scientific fields but can be applied to any discipline.

How to Write a Narrative Review (Tips for Undergrad Students)

Most undergraduate students conducting a capstone research project will be writing narrative reviews. Below is a five-step process for conducting a simple review of the literature for your project.

• Search for Relevant Literature: Use scholarly databases related to your field of study, provided by your university library, along with appropriate search terms to identify key scholarly articles that have been published on your topic.
• Evaluate and Select Sources: Filter the source list by selecting studies that are directly relevant and of sufficient quality, considering factors like credibility , objectivity, accuracy, and validity.
• Analyze and Synthesize: Review each source and summarize the main arguments  in one paragraph (or more, for postgrad). Keep these summaries in a table.
• Identify Themes: With all studies summarized, group studies that share common themes, such as studies that have similar findings or methodologies.
• Write the Review: Write your review based upon the themes or subtopics you have identified. Give a thorough overview of each theme, integrating source data, and conclude with a summary of the current state of knowledge then suggestions for future research based upon your evaluation of what is lacking in the literature.

Literature reviews don’t have to be as scary as they seem. Yes, they are difficult and require a strong degree of comprehension of academic studies. But it can be feasibly done through following a structured approach to data collection and analysis. With my undergraduate research students (who tend to conduct small-scale qualitative studies ), I encourage them to conduct a narrative literature review whereby they can identify key themes in the literature. Within each theme, students can critique key studies and their strengths and limitations , in order to get a lay of the land and come to a point where they can identify ways to contribute new insights to the existing academic conversation on their topic.

Frequently asked questions 

What is a literature review .

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 

2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example 

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:  

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Conducting a literature review 

Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1  

Choose a Topic and Define the Research Question:  

• Select a topic that is relevant to your field of study. 
• Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:  

• Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
• Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
• Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:  

• Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
• Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:  

• Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
• Record and document your search strategy for transparency and replicability. 
• Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:  

• Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
• Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
• Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
• Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
• Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:  

• Literature review outline should be based on themes, chronological order, or methodological approaches. 
• Write a clear and coherent narrative that synthesizes the information gathered. 
• Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
• Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research.

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Prevent plagiarism, run a free check.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

Literature Review Example

A literature review is a summary of the existing knowledge and research on a particular subject. by identifying gaps in the literature, it provides a foundation for future research. as such, it’s a crucial first step in any research project..

What is a literature review?

A literature review serves several purposes:

• identifies knowledge gaps
• evaluates the quality of existing research
• provides a foundation for newly presented research

Looking at existing examples of literature reviews is beneficial to get a clear understanding of what they entail. Find examples of a literature review by using an academic search engine (e.g. Google Scholar). As a starting point, search for your keyword or topic along with the term "literature review".

Example of literature review

Identify the research question or topic, making it as narrow as possible. In this example of a literature review, we review the anxiolytic (anti-anxiety) activity of Piper methysticum , or Kava .

Let's walk through the steps in the process with this literature review example.

Define the research question

First, identify the research question or topic, making it as narrow as possible. In this literature review example, we're examining the effects of urbanization on the migration of birds.

Search for relevant literature

Searching for relevant studies is arguably the most important aspect of the literature review.

Start by identifying keywords and phrases related to the topic and use them to search academic journals and databases ( Google Scholar , BASE , PubMed , etc.). For our example, you might start with "the effects of urbanization on bird migration", but after researching the field, discover that other terms like "avian migration" and "avian populations" are more commonly used.

Search for your keywords in Litmaps to find some initial articles to explore the field from. You can then use Litmaps to find additinal sources and curate a whole library of literature on your topic.

Search for your keywords in Litmaps, and select a starting article. This will return a visualization containing suggestions for relevant articles on your literature review topic. Review these to start curating your library.

Evaluate the sources

Evaluate the relevance and quality of the sources found by reading abstracts of the most relevant articles. Additionally, consider the publication venue, year of publication and other salient measures to identify the reliability and relevance of the source.

Read and analyze the sources

Take notes on the key findings, methodologies, and theoretical frameworks used in the studies.

Use a research-friendly note-taking software, like Obsidian , that provide #tags to keep track of key concepts.

Organize the literature

Organize the literature according to themes, subtopics, or categories, which will help outline the layout of the literature review.

Tag keywords using a tool like Obsidian to help organize papers into subtopics for the review.

Write the literature review

Summarize and synthesize the findings from the sources analyzed. Start with an introduction that defines the research question, followed by the themes, subtopics, or categories identified. After that, provide a discussion or conclusion that addresses any gaps in the literature to motivate future research. Lastly, edit and revise your review to ensure it is well-structured, clear, and concise. The example below is from a review paper, which includes a table comparing the different sources evaluated. Such tables can be useful if you are conducting a comprehensive review.

If you're conducting a comprehensive review, you can include a table of sources reviewed in your process, like the one above from this publication .

Cite and reference the sources

Lastly, cite and reference the sources used in the literature review. Consider any referencing style requirements of the institution or journal you're submitting to. APA is the most common. However, you may need to familiarize yourself with other citation styles such as MLA, Chicago, or MHRA depending on your venue. See the image below for a literature review example APA of references. To cite references you've saved in Litmaps, you can move your saved articles from Litmaps to a reference manager (i.e. Zotero, Mendeley, EndNote, etc.) and then export their bibliography from there. Here's how to export articles from Litmaps.

Use a reference manager tool like Zotero to easily export which makes them easy to manage, like in this APA literature review example.

A successful literature review tells a brief story about the topic at hand and leaves the reader a clear notion of what has been covered. Most importantly, a literature review addresses any gaps in the field and frames newly presented research. Understand the key steps and look at literature review examples in order to create a high quality review.

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

You can also search for this author in PubMed   Google Scholar

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

How To Write A Literature Review - A Complete Guide

Table of Contents

A literature review is much more than just another section in your research paper. It forms the very foundation of your research. It is a formal piece of writing where you analyze the existing theoretical framework, principles, and assumptions and use that as a base to shape your approach to the research question.

Curating and drafting a solid literature review section not only lends more credibility to your research paper but also makes your research tighter and better focused. But, writing literature reviews is a difficult task. It requires extensive reading, plus you have to consider market trends and technological and political changes, which tend to change in the blink of an eye.

Now streamline your literature review process with the help of SciSpace Copilot. With this AI research assistant, you can efficiently synthesize and analyze a vast amount of information, identify key themes and trends, and uncover gaps in the existing research. Get real-time explanations, summaries, and answers to your questions for the paper you're reviewing, making navigating and understanding the complex literature landscape easier.

In this comprehensive guide, we will explore everything from the definition of a literature review, its appropriate length, various types of literature reviews, and how to write one.

What is a literature review?

A literature review is a collation of survey, research, critical evaluation, and assessment of the existing literature in a preferred domain.

Eminent researcher and academic Arlene Fink, in her book Conducting Research Literature Reviews , defines it as the following:

“A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.

Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic, and to demonstrate to your readers how your research fits within a larger field of study.”

Simply put, a literature review can be defined as a critical discussion of relevant pre-existing research around your research question and carving out a definitive place for your study in the existing body of knowledge. Literature reviews can be presented in multiple ways: a section of an article, the whole research paper itself, or a chapter of your thesis.

A literature review does function as a summary of sources, but it also allows you to analyze further, interpret, and examine the stated theories, methods, viewpoints, and, of course, the gaps in the existing content.

As an author, you can discuss and interpret the research question and its various aspects and debate your adopted methods to support the claim.

What is the purpose of a literature review?

A literature review is meant to help your readers understand the relevance of your research question and where it fits within the existing body of knowledge. As a researcher, you should use it to set the context, build your argument, and establish the need for your study.

What is the importance of a literature review?

The literature review is a critical part of research papers because it helps you:

• Gain an in-depth understanding of your research question and the surrounding area
• Convey that you have a thorough understanding of your research area and are up-to-date with the latest changes and advancements
• Establish how your research is connected or builds on the existing body of knowledge and how it could contribute to further research
• Elaborate on the validity and suitability of your theoretical framework and research methodology
• Identify and highlight gaps and shortcomings in the existing body of knowledge and how things need to change
• Convey to readers how your study is different or how it contributes to the research area

How long should a literature review be?

Ideally, the literature review should take up 15%-40% of the total length of your manuscript. So, if you have a 10,000-word research paper, the minimum word count could be 1500.

Your literature review format depends heavily on the kind of manuscript you are writing — an entire chapter in case of doctoral theses, a part of the introductory section in a research article, to a full-fledged review article that examines the previously published research on a topic.

Another determining factor is the type of research you are doing. The literature review section tends to be longer for secondary research projects than primary research projects.

What are the different types of literature reviews?

All literature reviews are not the same. There are a variety of possible approaches that you can take. It all depends on the type of research you are pursuing.

Here are the different types of literature reviews:

Argumentative review

It is called an argumentative review when you carefully present literature that only supports or counters a specific argument or premise to establish a viewpoint.

Integrative review

It is a type of literature review focused on building a comprehensive understanding of a topic by combining available theoretical frameworks and empirical evidence.

Methodological review

This approach delves into the ''how'' and the ''what" of the research question —  you cannot look at the outcome in isolation; you should also review the methodology used.

Systematic review

This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research and collect, report, and analyze data from the studies included in the review.

Meta-analysis review

Meta-analysis uses statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects than those derived from the individual studies included within a review.

Historical review

Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and identify future research's likely directions.

Theoretical Review

This form aims to examine the corpus of theory accumulated regarding an issue, concept, theory, and phenomenon. The theoretical literature review helps to establish what theories exist, the relationships between them, the degree the existing approaches have been investigated, and to develop new hypotheses to be tested.

Scoping Review

The Scoping Review is often used at the beginning of an article, dissertation, or research proposal. It is conducted before the research to highlight gaps in the existing body of knowledge and explains why the project should be greenlit.

State-of-the-Art Review

The State-of-the-Art review is conducted periodically, focusing on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic and highlights where there are still disagreements.

Can you use the first person in a literature review?

When writing literature reviews, you should avoid the usage of first-person pronouns. It means that instead of "I argue that" or "we argue that," the appropriate expression would be "this research paper argues that."

Do you need an abstract for a literature review?

Ideally, yes. It is always good to have a condensed summary that is self-contained and independent of the rest of your review. As for how to draft one, you can follow the same fundamental idea when preparing an abstract for a literature review. It should also include:

• The research topic and your motivation behind selecting it
• A one-sentence thesis statement
• An explanation of the kinds of literature featured in the review
• Summary of what you've learned
• Conclusions you drew from the literature you reviewed
• Potential implications and future scope for research

Here's an example of the abstract of a literature review

Is a literature review written in the past tense?

Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present perfect tenses.

How many sources for a literature review?

There are multiple approaches to deciding how many sources to include in a literature review section. The first approach would be to look level you are at as a researcher. For instance, a doctoral thesis might need 60+ sources. In contrast, you might only need to refer to 5-15 sources at the undergraduate level.

The second approach is based on the kind of literature review you are doing — whether it is merely a chapter of your paper or if it is a self-contained paper in itself. When it is just a chapter, sources should equal the total number of pages in your article's body. In the second scenario, you need at least three times as many sources as there are pages in your work.

Quick tips on how to write a literature review

To know how to write a literature review, you must clearly understand its impact and role in establishing your work as substantive research material.

You need to follow the below-mentioned steps, to write a literature review:

• Outline the purpose behind the literature review
• Search relevant literature
• Examine and assess the relevant resources
• Discover connections by drawing deep insights from the resources
• Structure planning to write a good literature review

1. Outline and identify the purpose of  a literature review

As a first step on how to write a literature review, you must know what the research question or topic is and what shape you want your literature review to take. Ensure you understand the research topic inside out, or else seek clarifications. You must be able to the answer below questions before you start:

• How many sources do I need to include?
• What kind of sources should I analyze?
• How much should I critically evaluate each source?
• Should I summarize, synthesize or offer a critique of the sources?
• Do I need to include any background information or definitions?

Additionally, you should know that the narrower your research topic is, the swifter it will be for you to restrict the number of sources to be analyzed.

2. Search relevant literature

Dig deeper into search engines to discover what has already been published around your chosen topic. Make sure you thoroughly go through appropriate reference sources like books, reports, journal articles, government docs, and web-based resources.

You must prepare a list of keywords and their different variations. You can start your search from any library’s catalog, provided you are an active member of that institution. The exact keywords can be extended to widen your research over other databases and academic search engines like:

• Google Scholar
• Microsoft Academic
• Science.gov

Besides, it is not advisable to go through every resource word by word. Alternatively, what you can do is you can start by reading the abstract and then decide whether that source is relevant to your research or not.

Additionally, you must spend surplus time assessing the quality and relevance of resources. It would help if you tried preparing a list of citations to ensure that there lies no repetition of authors, publications, or articles in the literature review.

3. Examine and assess the sources

It is nearly impossible for you to go through every detail in the research article. So rather than trying to fetch every detail, you have to analyze and decide which research sources resemble closest and appear relevant to your chosen domain.

While analyzing the sources, you should look to find out answers to questions like:

• What question or problem has the author been describing and debating?
• What is the definition of critical aspects?
• How well the theories, approach, and methodology have been explained?
• Whether the research theory used some conventional or new innovative approach?
• How relevant are the key findings of the work?
• In what ways does it relate to other sources on the same topic?
• What challenges does this research paper pose to the existing theory
• What are the possible contributions or benefits it adds to the subject domain?

Be always mindful that you refer only to credible and authentic resources. It would be best if you always take references from different publications to validate your theory.

Always keep track of important information or data you can present in your literature review right from the beginning. It will help steer your path from any threats of plagiarism and also make it easier to curate an annotated bibliography or reference section.

4. Discover connections

At this stage, you must start deciding on the argument and structure of your literature review. To accomplish this, you must discover and identify the relations and connections between various resources while drafting your abstract.

A few aspects that you should be aware of while writing a literature review include:

• Rise to prominence: Theories and methods that have gained reputation and supporters over time.
• Constant scrutiny: Concepts or theories that repeatedly went under examination.
• Contradictions and conflicts: Theories, both the supporting and the contradictory ones, for the research topic.
• Knowledge gaps: What exactly does it fail to address, and how to bridge them with further research?
• Influential resources: Significant research projects available that have been upheld as milestones or perhaps, something that can modify the current trends

Once you join the dots between various past research works, it will be easier for you to draw a conclusion and identify your contribution to the existing knowledge base.

5. Structure planning to write a good literature review

There exist different ways towards planning and executing the structure of a literature review. The format of a literature review varies and depends upon the length of the research.

Like any other research paper, the literature review format must contain three sections: introduction, body, and conclusion. The goals and objectives of the research question determine what goes inside these three sections.

Nevertheless, a good literature review can be structured according to the chronological, thematic, methodological, or theoretical framework approach.

A literature review surveys prior research published in books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated. Literature reviews are designed to provide an overview of sources you have used in researching a particular topic and to demonstrate to your readers how your research fits within existing scholarship about the topic.

Fink, Arlene. Conducting Research Literature Reviews: From the Internet to Paper . Fourth edition. Thousand Oaks, CA: SAGE, 2014.

Importance of a Good Literature Review

A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:

• Give a new interpretation of old material or combine new with old interpretations,
• Trace the intellectual progression of the field, including major debates,
• Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
• Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.

Given this, the purpose of a literature review is to:

• Place each work in the context of its contribution to understanding the research problem being studied.
• Describe the relationship of each work to the others under consideration.
• Identify new ways to interpret prior research.
• Reveal any gaps that exist in the literature.
• Resolve conflicts amongst seemingly contradictory previous studies.
• Identify areas of prior scholarship to prevent duplication of effort.
• Point the way in fulfilling a need for additional research.
• Locate your own research within the context of existing literature [very important].

Types of Literature Reviews

It is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally among scholars that become part of the body of epistemological traditions within the field.

In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.

Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].

Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.

Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.

Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem . Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.

Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

NOTE: Most often the literature review will incorporate some combination of types. For example, a review that examines literature supporting or refuting an argument, assumption, or philosophical problem related to the research problem will also need to include writing supported by sources that establish the history of these arguments in the literature.

Structure and Writing Style

I.  Thinking About Your Literature Review

The structure of a literature review should include the following in support of understanding the research problem :

• An overview of the subject, issue, or theory under consideration, along with the objectives of the literature review,
• Division of works under review into themes or categories [e.g. works that support a particular position, those against, and those offering alternative approaches entirely],
• An explanation of how each work is similar to and how it varies from the others,
• Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research.

The critical evaluation of each work should consider :

• Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?
• Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?
• Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
• Persuasiveness -- which of the author's theses are most convincing or least convincing?
• Validity -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?

II.  Development of the Literature Review

Four Basic Stages of Writing 1.  Problem formulation -- which topic or field is being examined and what are its component issues? 2.  Literature search -- finding materials relevant to the subject being explored. 3.  Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4.  Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.

Consider the following issues before writing the literature review: Clarify If your assignment is not specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1.  Roughly how many sources would be appropriate to include? 2.  What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3.  Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4.  Should I evaluate the sources in any way beyond evaluating how they relate to understanding the research problem? 5.  Should I provide subheadings and other background information, such as definitions and/or a history? Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read, such as required readings in the course syllabus, are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make the act of reviewing easier if you first limit scope of the research problem. A good strategy is to begin by searching the USC Libraries Catalog for recent books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.

III.  Ways to Organize Your Literature Review

Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] A thematic literature review is the most common approach to summarizing prior research in the social and behavioral sciences. Thematic reviews are organized around a topic or issue, rather than the progression of time, although the progression of time may still be incorporated into a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it would still be organized chronologically reflecting technological developments in media. The difference in this example between a "chronological" and a "thematic" approach is what is emphasized the most: themes related to the role of the Internet in presidential politics. Note that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point being made. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.

Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. However, only include what is necessary for the reader to locate your study within the larger scholarship about the research problem.

Here are examples of other sections, usually in the form of a single paragraph, you may need to include depending on the type of review you write:

• Current Situation : Information necessary to understand the current topic or focus of the literature review.
• Sources Used : Describes the methods and resources [e.g., databases] you used to identify the literature you reviewed.
• History : The chronological progression of the field, the research literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
• Selection Methods : Criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed [i.e., scholarly] sources.
• Standards : Description of the way in which you present your information.
• Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?

IV.  Writing Your Literature Review

Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.

Use Evidence A literature review section is, in this sense, just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information, but that are not key to understanding the research problem, can be included in a list of further readings . Use Quotes Sparingly Some short quotes are appropriate if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, is not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute for using your own words in reviewing the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work and the work of others. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.

V.  Common Mistakes to Avoid

These are the most common mistakes made in reviewing social science research literature.

• Sources in your literature review do not clearly relate to the research problem;
• You do not take sufficient time to define and identify the most relevant sources to use in the literature review related to the research problem;
• Relies exclusively on secondary analytical sources rather than including relevant primary research studies or data;
• Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
• Does not describe the search procedures that were used in identifying the literature to review;
• Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
• Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Writing Tip

Break Out of Your Disciplinary Box!

Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.

Frodeman, Robert. The Oxford Handbook of Interdisciplinarity . New York: Oxford University Press, 2010.

Another Writing Tip

Don't Just Review for Content!

While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:

• How are they organizing their ideas?
• What methods have they used to study the problem?
• What theories have been used to explain, predict, or understand their research problem?
• What sources have they cited to support their conclusions?
• How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?

When you begin to write your literature review section, you'll be glad you dug deeper into how the research was designed and constructed because it establishes a means for developing more substantial analysis and interpretation of the research problem.

Hart, Chris. Doing a Literature Review: Releasing the Social Science Research Imagination . Thousand Oaks, CA: Sage Publications, 1 998.

Yet Another Writing Tip

When Do I Know I Can Stop Looking and Move On?

Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:

• Look for repeating patterns in the research findings . If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research?  Does it forge a new path? Or, does is merely add more of the same thing being said?
• Look at sources the authors cite to in their work . If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been generated to address the research problem.
• Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review [see next sub-tab]. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. Here again, if the same authors are being cited again and again, this may indicate no new literature has been written on the topic.

How to write a literature review

Below are the steps you should follow when crafting a lit review for your class assignment.

• It's preferable if you can select a topic that you find interesting, because this will make the work seem less like work. 
• It's also important to select a topic that many researchers have already explored. This way, you'll actually have "literature" to "review."
• Sometimes, doing a very general search and reading other literature reviews can reveal a topic or avenue of research to you. 
• It's important to gain an understanding of your topic's research history, in order to properly comprehend how and why the current (emerging) research exists.
• One trick is to look at the References (aka Bibliographies aka Works Cited pages) of any especially relevant articles, in order to expand your search for those same sources. This is because there is often overlap between works, and if you're paying attention, one source can point you to several others.
• One method is to start with the most recently-published research and then use their citations to identify older research, allowing you to piece together a timeline and work backwards. 
• Chronologically : discuss the literature in order of its writing/publication. This will demonstrate a change in trends over time, and/or detail a history of controversy in the field, and/or illustrate developments in the field.
• Thematically : group your sources by subject or theme. This will show the variety of angels from which your topic has been studied. This method works well if you are trying to identify a sub-topic that has so far been overlooked by other researchers.
• Methodologically : group your sources by methodology. For example, divide the literature into categories like qualitative versus quantitative, or by population or geographical region, etc. 
• Theoretically : group your sources by theoretical lens. Your textbook should have a section(s) dedicated to the various theories in your field. If you're unsure, you should ask your professor.
• Are there disagreements on some issues, and consensus on others?
• How does this impact the path of research and discovery?
• Many articles will have a Limitations section, or a Discussion section, wherein suggestions are provided for next steps to further the research.
• These are goldmines for helping you see a possible outlook of the situation. 
• Identifying any gaps in the literature that are of a particular interest to your research goals will help you justify why your own research should be performed. 
• Be selective about which points from the source you use. The information should be the most important and the most relevant. 
• Use direct quotes sparingly, and don't rely too heavily on summaries and paraphrasing. You should be drawing conclusions about how the literature relates to your own analysis or the other literature. 
• Synthesize your sources. The goal is not to make a list of summaries, but to show how the sources relate to one another and to your own analysis. 
• At the end, make suggestions for future research. What subjects, populations, methodologies, or theoretical lenses warrant further exploration? What common flaws or biases did you identify that could be corrected in future studies? 
• Common citation styles for sociology classes include APA and ASA.

Understanding how a literature review is structured will help you as you craft your own. 

Below is information and example articles that you should review, in order to comprehend why they are written a certain way.

Below are some very good examples of Literature Reviews:

Cyberbullying: How Physical Intimidation Influences the Way People are Bullied

Use of Propofol and Emergence Agitation in Children

Eternity and Immortality in Spinoza's 'Ethics'

As you read these, take note of the sections that comprise the main structure of each one:

• Introduction 
• Summarize sources
• Synthesize sources

Below are some articles that provide very good examples of an "Introduction" section, which includes a "Review of the Literature."

• Sometimes, there is both an Introduction section, and a separate Review of the Literature section (oftentimes, it simply depends on the publication)

How To Structure Your Literature Review

3 options to help structure your chapter.

By: Amy Rommelspacher (PhD) | Reviewer: Dr Eunice Rautenbach | November 2020 (Updated May 2023)

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As  we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

• Demonstrate your knowledge of the research topic
• Identify the gaps in the literature and show how your research links to these
• Provide the foundation for your conceptual framework (if you have one)
• Inform your own  methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter. 

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess. 

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write. 

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an  introduction , a  body   and a  conclusion . 

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you  will   and  won’t   be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies). 

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way. 

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking)  three options  for organising your literature review.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

• What is the earliest literature published relating to this topic?
• How has the field changed over time? Why?
• What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

Here are some questions to ask yourself when structuring your literature review by themes:

• Are there any patterns that have come to light in the literature?
• What are the central themes and categories used by the researchers?
• Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed  methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question  how  existing research has been conducted, as opposed to  what  the conclusions and/or findings the research were.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

• Which methodologies have been utilised in this field?
• Which methodology is the most popular (and why)?
• What are the strengths and weaknesses of the various methodologies?
• How can the existing methodologies inform my own methodology?

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve  discussed how to structure your literature review for maximum impact. Here’s a quick recap of what  you need to keep in mind when deciding on your literature review structure:

• Just like other chapters, your literature review needs a clear introduction , body and conclusion .
• The introduction section should provide an overview of what you will discuss in your literature review.
• The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
• The conclusion section should draw together the key findings of your literature review and link them to your research questions.

Great work. This is exactly what I was looking for and helps a lot together with your previous post on literature review. One last thing is missing: a link to a great literature chapter of an journal article (maybe with comments of the different sections in this review chapter). Do you know any great literature review chapters?

I agree with you Marin… A great piece

I agree with Marin. This would be quite helpful if you annotate a nicely structured literature from previously published research articles.

Awesome article for my research.

I thank you immensely for this wonderful guide

It is indeed thought and supportive work for the futurist researcher and students

Very educative and good time to get guide. Thank you

Great work, very insightful. Thank you.

Thanks for this wonderful presentation. My question is that do I put all the variables into a single conceptual framework or each hypothesis will have it own conceptual framework?

Thank you very much, very helpful

This is very educative and precise . Thank you very much for dropping this kind of write up .

Pheeww, so damn helpful, thank you for this informative piece.

I’m doing a research project topic ; stool analysis for parasitic worm (enteric) worm, how do I structure it, thanks.

comprehensive explanation. Help us by pasting the URL of some good “literature review” for better understanding.

great piece. thanks for the awesome explanation. it is really worth sharing. I have a little question, if anyone can help me out, which of the options in the body of literature can be best fit if you are writing an architectural thesis that deals with design?

I am doing a research on nanofluids how can l structure it?

Beautifully clear.nThank you!

Lucid! Thankyou!

Brilliant work, well understood, many thanks

I like how this was so clear with simple language 😊😊 thank you so much 😊 for these information 😊

Insightful. I was struggling to come up with a sensible literature review but this has been really helpful. Thank you!

You have given thought-provoking information about the review of the literature.

Thank you. It has made my own research better and to impart your work to students I teach

I learnt a lot from this teaching. It’s a great piece.

I am doing research on EFL teacher motivation for his/her job. How Can I structure it? Is there any detailed template, additional to this?

You are so cool! I do not think I’ve read through something like this before. So nice to find somebody with some genuine thoughts on this issue. Seriously.. thank you for starting this up. This site is one thing that is required on the internet, someone with a little originality!

I’m asked to do conceptual, theoretical and empirical literature, and i just don’t know how to structure it

Asking questions are actually fastidious thing if you are not understanding anything fully, but this article presents good understanding yet.

thank you SOOO much it is really helpful ..

39 Best Literature Review Examples (Guide with Samples)

A literature review is a compilation of current knowledge on a particular topic derived from the critical evaluation of different scholarly sources such as books, articles, and publications, which is then presented in an organized manner to relate to a specific research problem being investigated.

It highlights the methods, relevant theories, and gaps in existing research on a particular subject. It can be both a summary and synthesis of information on a specific topic. A summary reiterates key information from scholarly sources, while synthesis is a new interpretation or combination of new and old material. 

As a synthesis, it can outline the intellectual progression of knowledge in a particular field or topic, which might involve stating key debates throughout the advancement period.  

Literature Review Examples

Purpose of Literature Review

Literature reviews have different purposes in scholarly articles, research papers , and books, depending on the discipline at hand. First and foremost, reviews are generally meant to showcase the extensive research carried out by an author on a particular topic and their findings, which will form the foundation of the research. It then summarizes the information to show the author’s familiarity with the topic in question.

The review also demonstrates the relationship between the topic being investigated and other topics that were under consideration. Finally, it outlines the gaps in the previous works of other scholars, which create areas of research.

Literature reviews provide a new interpretation of previous scholarly publications and aim to resolve conflicting studies done in the past. In addition, identifying existing gaps in a particular research area illustrates the starting point of the research.

Literature Review vs. Academic Research Paper

A research paper presents new ideas, arguments, and approaches toward a particular topic. The conclusions of a research paper will be based on the analysis and interpretation of raw data collected by the author and an original study. On the other hand, a literature review is based on the findings of other publications. Thus, the review highlights the author’s understanding of a topic based on the previously conducted research. It is part of a research paper.

Where, When, and Why

The need for a literature review in a publication will vary from one situation to the other and the field/discipline of research. These two factors determine what is expected from the lit review. For example, a scientific review will be more analytical on the methods and results of previous research. In contrast, a philosophical review will be more argumentative, highlighting the discrepancies and correspondences between scholars.

It can either be part of a publication or a stand-alone document. As part of a research publication, it is often placed after the introduction to the topic outlining knowledge about a particular topic and critical sources that formed the foundation of the research. As an individual document, it is prepared by students as part of course study to aid the students in familiarizing themselves with different topics in their field of study.

Lit reviews also guide students to help them synthesize theoretical methodologies and frameworks to adopt in academic research . As a publication, literature reviews are used to document existing information about a topic for readers (other scholars) to go through for whatever reasons they may have. Published studies are essentially helpful to new scholars getting into any field of research.

Types of Literature Review

Before looking into how to write a literature review, it is vital to understand the different types. The type will usually depend on the objective approach of the author.

Common types are:  

Argumentative review

An argumentative review is adopted when the research paper or publication is meant to take a contrarian viewpoint on a particular subject. The review analyses an existing argument, philosophical problem, assumption, or conclusion outlined in different studies with an objective to either support or oppose the argument. 

Integrative review

An integrative review integrates secondary data to develop new perspectives and frameworks on a topic. This is more prevalent in research that does not involve primary data. In addition, integrative reviews are more familiar with social sciences.       

Historical review

Historical reviews are used when scholars or authors place a particular idea, concept, theory, or research in a historical context. It examines the idea, theory, or issue from the first time it was discussed and outlines its evolution throughout a given period.  

Methodological review

Methodological reviews look at how a specific theory, concept, results, or findings were developed. Therefore, methodological reviews will analyze the different methods used by different scholars to arrive at conclusions or knowledge about the topic being investigated.

Some of the methods scholars use in different disciplines to obtain information are interviewing, sampling, practical experiments/data collection, research approaches, critical thinking, social experiments, etc.

Methodological reviews are hence used to discuss tested methods of research and ethics that a researcher should be aware of before undertaking their investigations.  

Systematic review

A systematic review is a more detailed and comprehensive review compared to other types of lit reviews. It highlights any existing research evidence associated with a clearly defined research problem or question. The evidence is collected, analyzed, and reported in a summarized but detailed manner. Systematic reviews are popularly presented as a cause-and-effect structure.

Theoretical review

A theoretical review delves into the different theories regarding a particular issue, challenge, concept, or theory. It identifies their inadequacy in explaining the issue or concept at hand. The review then identifies the relationships between the identified theories, and the degree of research done and poses novel hypotheses to be investigated.

Organization of a Literature Review

How an author organizes a literature review will depend on what they aim to achieve. As a consequence, there are multiple ways of organizing it which are discussed below:

Chronological 

A chronological format outlines knowledge on a particular topic based on when the scholarly source of information was published. Starting with the earliest followed up to the most recent chronological order. This format should be used if there is a clear chronological order in the development of the information; therefore, it will not be applicable in some cases. Instead, key turning points, patterns, and events that impacted the direction of the knowledge should be outlined.  

By publication

It can be organized in the scholarly publications reviewed by the author, scholar, or student. The by-publication format should only improve the review and facilitate what the author aims to accomplish. 

Scholars or students can adopt a dominant trend in research, such as history, developmental stages, steps involved in a process, etc.

Methodological

A methodological format is based on the methods used by the researcher. Thus, the order of contents in the lit review will depend on the method they will use to carry out their research, knowledge obtained from the first method appears first, and the rest of the information follows in the same order according to the methods used by the author.  

Literature reviews organized in a thematic format revolve around the subject being investigated in no order. It is, therefore, ordinarily up to the researcher or author to determine how they intend to outline the information. A thematic format will crossover from one period and publication to another, but can sometimes incorporate a chronological order.

Theoretical

Literature reviews organized in a theoretical format have their contents organized in an abstract framework established by the author to discuss different concepts, theories, and concepts and how they relate to the research at hand.

Additional sections

Depending on the objective, other sections do not fit under conventional lit review formats that one may need to add. Below are some of the sections that authors or students can include in the lit review:

• Current situation: The review can have information about the current state of things regarding the topic at hand to facilitate further understanding.
• History: Researchers can summarize the subject under investigation, literature, or concept if the review is not already in chronological format.
• Selection methods: Lit reviews are known to outline the methods or criteria used in selecting the way to present information and scholarly sources referenced in the review.
• Standards: it can also include the standards used in choosing the format to present information in the review and the scholarly literature used in the research.
• Further questions for research: The review can include questions emanating from the review and how the researcher will further explore their research to address the queries raised.

Considerations Before Writing a Literature Review

Preparation is essential when it comes to writing. The objective should be to come up with a review that satisfactorily explores the topic being discussed. The following considerations are steps towards that if incorporated into the writing process:

Authors should seek clarification from mentors or supervisors before commencing the writing process. First, determine what is expected from the lit review. The type and number of sources to be used, the assignment (summarize, synthesize, or critique), and the type of information provided should be clear.

Find models

You should review literature from other authors in the same discipline and evaluate how those authors presented their lit reviews. Previous lit reviews can be used as guides that point authors in the right direction when writing their lit reviews.

Narrow your topic

It is always advantageous to narrow down the research topic to a specific area of research; that way, the number of sources can also be reduced. Even though conducting research will usually involve extensive research on all available materials about a particular topic, having a well-defined topic simplifies the task at hand.

Current sources

Determine if the research project or discipline ought to be based on the most recent findings or information. It is common for knowledge to become obsolete, especially in disciplines where discoveries and new inventions are made fast. If the lit review should be based on current knowledge, limit the sources to the most recent literature. Some disciplines will typically have a limit on how old the sources should be.  

How to Write a Literature Review (Expert Guide)

Once all pre-writing considerations have been taken into account, it is time to write the document. At this point, you should already be aware of what you wish to accomplish with the literature review, and the steps to writing an exemplary lit review are mentioned below:

Problem formulation

First and foremost, clearly define the topic (research area) to be investigated. For students, this will sometimes be given as an assignment. However, the research could be an academic project, which means that the author has to come up with the problem and define it themselves.

Search for relevant studies

Once the problem is clearly expressed, you should search for studies related to the topic, concept, theory, or idea and questions surrounding the topic. Most stand-alone lit reviews will generally attempt to answer a more concentrated question. On the internet, literature can be searched using keywords related to the research area. In addition to keywords, include vital variables such as synonyms and associated terms. The inclusion of Boolean operators and, or not, is also used to narrow down results to more specific publications.

Familiar sources for publications are:

• Google Scholar
• Library catalogue
• Econ lit (economics)
• Project Muse (humanities and social sciences)
• Inspec (physics, engineering, and computer science )
• Medline (life sciences and biomedicine)

Before selecting relevant studies, go through their abstract and determine if they fit the scope needed in the investigation. Use a list to note down any chosen works. Select landmark sources in the discipline.

Evaluation of sources/data

The next step is the evaluation stage . Evaluation involves a lot of reading. Evaluation can be done in two stages; overall skimming and thorough reading. During the second stage of this step, be critical, ask questions, and take many notes.

Some of the questions authors or researchers should ask themselves are:

• What is the author’s objective? What problem, concept, or theory are they putting across?
• What are the main concepts?
• What are the methodologies used by the author to arrive at the results and conclusions?
• What are the strengths and weaknesses of the results and conclusions?

Use credible sources. Most cited sources are preferred as they indicate their influence in the field. Also, keep track of the citations to be later incorporated.

Identify themes, debates, and gaps

While reading the sources, identify key patterns, themes, debates/arguments, and gaps in each literature. These elements help tie the literature to the topic under investigation. Look for consistent patterns, themes, questions, challenges, methods, and inconsistencies in the same. Consistencies present critical information for consideration, while inconsistencies present opportunities for research areas.

Outline the structure

Formatting is part and parcel of a well-written work. Selecting the structure should start by creating an outline with all the information that will go into the lit review, then consider the different types of structures and select the most suitable. Next, take the basic structure of the introduction, body, and conclusion into consideration and start work from there. 

Analysis and interpretation 

Lastly, perform an in-depth analysis and interpretation of the information obtained from the scholarly research and put it into writing. The summarized, synthesized, and critically evaluated information is then written down in well-structured paragraphs that follow the chosen structure. Transition words are used to draw comparisons, connections, and contrasts.

Format 

Ordinarily, a literature review will have three key components: introduction, body, and conclusion. These components should appear in the document in the following order:

Introduction

An introduction should inform the reader which topic is being studied. It gives the reader an overall idea of the purpose and focus of the document. The introduction lets the reader know beforehand the key things that will be highlighted in the document. Therefore, the introduction should be brief and precise.

The next item is the body, where the primary purpose of the lit review is fulfilled. The body should take critical information from all the sources used and comprehensively present them. This is where the author reports the extensive analysis and interpretation results that they gathered from all the sources they reviewed. The body should be categorized into themes, ideas, and concepts within the main topic.

Lastly, a summary of what the lit review entails should be provided as a conclusion. The critical points obtained from examining the sources should be written down and linked to the primary subject of the review. Key points are those that have the most outstanding contribution to the research.

Studies used should be screened based on provenance (author’s credentials or credibility), methodology, objectivity, persuasiveness, and value related to the topic at hand.

Guidelines for Writing a Literature Review

To improve the delivery of information, there are certain elements that authors can incorporate. They are:

Use evidence

The lit review’s findings, interpretations, and general contents should be based on actual evidence or credible literature. Using citations is evidence of authentic information.

Be selective

There will always be a lot of information available from the reviewed sources. Authors should therefore be selective and discuss the key points that focus on the topic. Not all information must be included in the review.  

Word-for-word quotes are acceptable . This is even more so if a critical point or author-specific terminology or knowledge cannot be paraphrased. Quotes should, however, be used sparingly.

Summarize and synthesize

The information obtained from the sources should be summarized, and the author should use it to synthesize new arguments, concepts, or ideas related to their research.

Keep your voice

The literature review should reflect the author’s voice as it is a review of other people’s works. This can be done by starting and ending the paragraphs with an original voice, ideas, and wordings.

Use caution while paraphrasing

Any paraphrased information should be conveyed accurately and in the author’s words. A citation must always be done, even when paraphrasing has been done.

Proofread before submitting or publishing. Go through the document a few times and make the necessary changes. The review should be within the applicable guidelines. Check for language and any other errors and edit accordingly.

Do’s and Don’ts for a Literature Review 

Every researcher wants to introduce their readers to a particular topic in an informative and engaging manner. Below are tips that can be used to this effect.

The following things should be opted by the researcher when writing a lit review:

• Find a focus: Authors should take a direction, idea, concept, or argument and stick to it. The information conveyed should then be made to align with the chosen point of focus. Thus, the review is not simply a list of analyzed sources, but a detailed summary of how different sources have a focal point (intertwined).
• Well-chosen sources: The quality of the information will, to a great extent, be determined by the quality of sources used. Therefore, take time to select suitable sources and more value will be added to the review.
• Create an annotated bibliography: Creating an annotated bibliography is recommended as one reads their sources. The bibliography keeps track of sources and takes notes. This information can be used when writing the final lit review.
• Synthesize research: Information obtained from the relevant studies should be combined to come up with new or original ideas. You should present a new domain based on previous sources’ knowledge, not just restating the information.
• Argumentative approach: Well-written literature reviews will often argue to support an author’s stance on a particular topic. The author can choose to address how the author’s work is filling a particular gap or support one of the scholar’s arguments and perception towards a particular topic. However, this argumentative approach will not work in all situations; it is usually discipline-specific. 
• Convey it to the reader: It should let the reader know the document’s main idea, concept, or argument. This can be done by including a simple statement that compels the reader to think precisely and know what to expect.
• Break out your disciplinary box: The research will often be multi-disciplinary. Literature reviews should then collect interdisciplinary information from multiple sources as they add novel dynamics to the topic under investigation. It should be noted that this does not imply that the researcher should substitute the literature from the topic’s discipline with that from other disciplines. This is usually an improvement strategy that adds substance to the review.
• Look for repeated patterns: Be attentive to pick out repeated ideas, findings, and concepts from different scholars as they will often illustrate agreed research dead-end or a scholarly conclusion.
• Don’t just review for content: When reviewing the literature, examine the content and other writing and presentation techniques. Look out for unique ways information has been presented, methods used, consistent citations, and non-textual elements such as graphs, and figures used to present information. In addition, the researcher identifies theories used to predict, explain, or understand phenomena within the discipline.
• Search Web of Science and Google Scholar: Conduct citation tracking about the leading scholars already identified in the search process. Scholars cited by multiple scholars outside the principal discipline will generally indicate that there are no new publications on the topic.

The following don’ts should be avoided:

• Do not select studies that are not directly related to the topic being investigated.
• Avoid rushing when identifying and selecting sources to use to research the problem.
• Avoid the use of secondary analytical sources. Instead, opt to use sources with primary research studies or data. Secondary analytical sources will often cite primary analytical sources; research should refer to them instead.
• Do not accept other scholarly findings, theories, or interpretations without critically examining and critiquing them.
• Researchers should not outline the search procedures used to identify scholarly sources for reviewing purposes.
• Avoid including isolated statistical findings without illustrating how they were arrived at using chi-squared or meta-analytic methods.
• Do not review studies that only validate the assumptions, stances, and concepts of your thesis; consider contradicting works with alternative and conflicting stances.

Frequently Asked Questions

It is written by researchers, authors, and students who must study literature to gather knowledge on a particular topic they are interested in.

It should be placed right after the introduction of the dissertation. It places the research in a scholarly context by summarizing existing knowledge on the particular topic.

Researchers and authors are not limited in terms of how many sources they can review. Students will usually have a given number of sources to review as an assignment. However, the number of sources referenced in a lit review will vary from one topic or discipline to the other. Some topics have a vast catalog of available sources, while others have minimal sources, especially emerging issues. It is, however, advised that each key point discussed should have at least 2-3 references/sources. For example, a 10-page lit review will have an average of 30 references.

Metrics details

Improving the quality of midwifery education to international standards is critical to prepare competent midwives. Despite the recognised impact of competent midwives, little is known concerning the implementation of Competency-Based Education (CBE), especially in Africa, where poor investment in quality midwifery education has been reported.

The aim of this study is to scope and synthesize the existing literature on the implementation of CBE for midwifery programmes and its sustainability in Africa.

The scoping review methodology outlined by Arksey and O’Malley framework was adopted to explore the extent of the literature on the implementation of CBE for midwifery programmes and its sustainability in Africa. This framework directed the scoping review methodology, with reference to PRISMA-ScR guidelines.

A total sample of 72 studies were finally included in this scoping review. Reporting of the scoping review findings follows the PRISMA- ScR format. The study showed that of the 54 African countries as per the World Bank classification, after review of the full articles following the eligibility criteria for inclusion, literature on midwifery education programmes only spanned 17 African countries as at the time of this report. Of which, 11 are implementing CBE, 5 are still using Traditionally Based Approaches (TBA) while Problem-Based Learning (PBL) is the main teaching pedagogy used in Botswana. This review revealed that for the successful implementation of CBE, a CBE curriculum implementation process must be strictly observed. Evidence from the literature confirmed that CBE has not been sustained in Africa. There is still a struggle to fully integrate the major components of the competency-based midwifery programme due to inadequate support and an inadequate monitoring system.

Conclusions

It is expedient that CBE implementation should be planned concurrently with its sustainability for it to be effective. Adequate training and support should be continuously provided to faculties, institutions, policy makers, professional bodies, students and other stakeholders for successful implementation and sustainability.

Peer Review reports

Introduction

Reports have identified that strengthening midwifery is critical to improved maternal and newborn health, globally [ 1 , 2 , 3 ]. However, poor quality midwifery care remains a major contributor to high maternal and neonatal death, especially in Low- and Middle-Income Countries (LMICs) [ 4 , 5 ] despite evidence suggesting that 87% of the incidence of Maternal Mortality Ratio (MMR) (MMR) can be alleviated through quality midwifery care provided by midwives that have been educated, trained, regulated and licensed according to the International Confederation of Midwives (ICM ) global standards for midwifery education [ 6 ]. Recently, the world recorded a 34% (223/100,000 live birth) reduction in MMR. While this is appreciable, it is insignificant in terms of realizing the promising Sustainable Development Goal (SDG) which aims to achieve reduced maternal death to less than 70/100,000 live births by 2030 [ 7 ]. Progress in improving maternal health remains stalled in LMICs where almost 95% of all maternal deaths occur from preventable causes, 70% of which disturbing statistics is accounted for by sub-Saharan Africa [ 8 ]. Midwives played a pivotal role in achieving the millennium development goals and their efforts have continued to be recognised as the most cost-effective solution to meet SDG targets [ 2 ]. However, to enable midwives to contribute significantly, quality midwifery education has been identified as an important approach to promoting quality midwifery care [ 9 , 10 ]. This approach involves improving the quality of midwifery education to international standards to prepare future midwives so that they are equipped with the appropriate competencies to enable the delivery of safe and high quality sexual and reproductive care required to achieve international SDG efforts [ 11 ].

The ICM with support from the World Health Organization (WHO) advocate the need to strengthen midwifery globally through the provision of standards for midwifery education and practice [ 12 , 13 ]. The Confederation maintained this vision over the years by communicating these global Standards for Midwifery Education with an emphasis on Competency-Based Education (CBE) to ensure consistency in practice and education of midwives [ 14 , 15 , 16 ]. However, nations are expected to interpret and adapt these global standards to midwifery educational programmes wherever these are located to prepare qualified midwives [ 16 ]. The title “qualified midwife” is appropriate for use by an individual who has been able to complete his/her midwifery education programme. And demonstrate competency in the practice of midwifery satisfactorily to earn a midwifery certificate and is registered and licensed to practice midwifery in the country where the education was obtained [ 17 ]. Midwives can acquire the specific knowledge and skills to become fully qualified midwives through three major educational pathways [ 18 ]. A direct-entry programme for midwifery, a post-nursing programme and a combined programme of Nursing and Midwifery [ 19 ]. However, regardless of the chosen pathways, it is expedient that countries meet the predetermined standards in CBE in midwifery curriculum to ensure the competency-based outcomes of midwifery education are equivalent [ 16 , 20 ]. Unfortunately, several inconsistencies apply to the implementation and sustainability of CBE Midwifery education with most countries still following the Traditional Based Approach (TBA) [ 16 ] probably due to poor planning and implementation process especially in Africa.

Competency-based education compared to Traditional-Based Approaches (TBA) continues to remain relevant, especially in professional healthcare education programmes including midwifery education [ 21 , 22 ]. There are four basic principles distinguishing CBE from TBA highlighted by Frank and colleagues which are CBE’s focus on outcomes of education and training, the learner’s capabilities against predetermined standards [ 23 ]. Furthermore, CBE requires a flexible curriculum with reduced emphasis on time and promotion of learners-centeredness The increasing popularity of CBE and the paradigm shift were necessary in response to the dynamic labor market that requires flexible, adaptive, and competent employees that can respond swiftly to the ever-changing work environment [ 22 , 24 , 25 ]. CBE in the professional health care education programme has focused on health care professionals with adequate capabilities necessary to provide high-quality care and ability to meet the population’s health demands [ 26 ]. CBE prepares graduates by focusing on the competencies acquired during their educational experience that are assessed against knowledge, skills, attitude, and achievement standards as outcomes of the curriculum [ 21 , 23 ].

Competency-based education is described as a curriculum or training program that provides comprehensive tasks to practice all the required competencies [ 26 ]. For the midwifery profession, competency-based education is an educational program of studies that is based on a complex combination of knowledge and skills acquisition, demonstration, values, and attitude in all aspects relating to the essential competencies required to become a qualified midwife [ 27 ]. The theory of CBE is an individualized programme, that aims to assess the theoretical and clinical competency of each midwifery student until competency proves satisfactory [ 27 , 28 ]. Faculties, including educators and clinical preceptors, involved in the training and clinical experience of students ought to work harmoniously to sustain CBE for midwifery educational programs [ 29 , 30 ]. Although proper implementation of CBE promises to realize the outcomes of education and training. However, studies have found that these expectations are difficult to achieve in reality due to inadequate knowledge of assessment of competency [ 31 , 32 , 33 , 34 , 35 ]. Despite the proven benefits of CBE, little is known about the implementation of CBE, especially in Africa, where poor investment in quality midwifery education has been reported [ 36 ]. Hence, this study will review the existing literature concerning the implementation of competency-based education for midwifery programs and its sustainability in Africa.

The scoping methodology, as outlined by Arksey and O’Malley, was adopted to explore the extent of the literature concerning the implementation of CBE for midwifery programmes, and its sustainability in Africa [ 37 ]. The Arksey and O’Malley five-step framework for conducting scoping reviews was used, namely: (1) identify the research question; (2) identify relevant studies; (3) perform study selection; (4) extract and chart the data; and (5) collate, summarize, and report the results. This framework directed the scoping review methodology, with reference also to additional PRISMA-ScR guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) [ 38 ].

Step 1: identify the Research question

This scoping review is guided by the following research questions:

What is the existing evidence of implementing CBE in midwifery education in Africa?

How has CBE for midwifery education been sustained in Africa?

Inclusion and exclusion criteria

The inclusion of eligible studies in this scoping review was determined following the Participants, Concept, and Context (PCC) framework [ 39 ]. Inclusion and exclusion criteria are listed in Table  1 . The review included literature published from January 2010 to April 2024 in the English language.

Step 2: identify relevant Studies

A comprehensive report identifying the relevant studies has been published previously [ 40 ]. Systematic and literature reviews which were considered relevant had their reference lists scrutinized manually for potential studies, however, the reviews were not considered for inclusion. This review considered English-only studies in Africa from 2010 to 2024. Reports published from 2010 which captured the International Confederation of Midwives (ICM) position statement on the implementation of CBE for midwifery programmes were equally considered [ 29 ].

Step 3: perform study selection

A total of 935 citations identified through database searching were imported into EndNote (v.21; Clarivate Analytics) and screened for duplicates. The remaining citations ( n  = 687) were uploaded into Rayyan review software (Qatar Computing Research Institute). The two independent reviewers (WBI and OA) conducted the initial screening to assess eligibility regarding the title and abstract and then conducted a full-text review using the PCC framework. Any disagreements during the selection process were resolved through discussion with the third senior reviewer (WBN).

Step 4: extract and chart the data

A data charting table was pre-developed to extract and chart relevant information from eligible studies. The reviewers conducted a pilot test on five included studies. Eligible studies were extracted by two independent reviewers (WBI and OA), while the third reviewer (WBN) validated the data extraction results. The data charting table, Table  2 , was reviewed independently and compared for consistency by the team of reviewers following the PCC framework. The year of implementation of CBE was added to existing variables (the type of study, year, setting or context, aims, study population, research design, research techniques, and summary of findings). The data charting Table 2 showed a comprehensive report of relevant information of eligible literatures. Using an iterative approach, the two reviewers independently coded the content of the data using Nvivio, seven themes were generated. The report of the review is summarized in the Figure: 1 , following the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) format.

Step 5: collate, summarize, and report the results

Table  1 shows the complete list of extracted articles conducted across 17 African countries from 2010 to 2024, most of which were reported in South Africa (32%). Despite not limiting the search by language, the majority of the articles were in English, except for two in Arabic and French. The research consisted mainly of qualitative studies ( n  = 19); eighteen (18) studies used quantitative methodology while seventeen (17) were mixed methods. Other designs included surveys ( n  = 6), case studies ( n  = 8), multi-method research designs ( n  = 1) and field action reports ( n  = 2) and conference presentations ( n  = 1). Figure  1 shows the report of the scoping review findings following the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) format.

The 935 articles originally identified from electronic database were uploaded to Rayyan, from which 138 duplicate records were removed, while a further 110 duplicates were detected and removed by automation. Of the 528remaining, 456 were eliminated: 264 of these did not relate to the concept of the study; 133 were conducted outside African countries or regions; 30 were published before 2010; 21 consisted of the wrong population (i.e., the participants were mainly nurses and others without any connection to midwifery); 8 were the wrong publication type (e.g. editorial, commentary, literature reviews). Following the grey literature search, a further 26 reports were discovered. Finally, a total sample of 72 studies were included in this scoping review. Table  2 shows the data charting table of the result.

PRISMA- ScR

Reporting of the scoping review findings follows the PRISMA- ScR flow chart format(Fig.  1 ) Subsequent content analysis using Graneheim and Lundman approach identified seven (7) themes from the literature and a narrative report presented [ 41 ] as follows; (a) midwifery curriculum (b) competency-based education curriculum implementation process (c) pedagogical approaches in CBE (d) Benefits of CBE (e) sustainability of CBE (f) facilitators of CBE implementation (g) challenges to CBE implementation.

Theme 1: midwifery curriculum

Midwifery curriculum generated two sub-themes comprising the types of midwifery curriculum implemented and the content of the midwifery curriculum.

Sub-theme1: Type of midwifery curriculum implemented

A thorough search of the published literature in Africa on midwifery education found 17 countries 11 of which are implementing CBE (South Africa, Rwanda, Tanzania, Uganda, Lesotho, Kenya, Egypt, Morocco, Malawi, Democratic Republic of Congo, Zambia), while 5 countries (Nigeria, Ethiopia, Ghana, Benin, Sierra Leone) are using Traditional-Based Approaches. Problem-Based Learning (PBL) is the main teaching pedagogy used in Botswana.

Sub-theme 2: Content of the Curriculla. (wide disparities within and across the countries)

The findings showed that the content of the curriculum differs appreciably among training institutions within African countries. Comparing the content of the curriculum to ICM global, essential competencies for midwifery practice revealed that a wide gap exists within institutions in a nation and across the African continent. A study assessing the curriculum in four countries found that, out of the ten pre-service curricula assessed, none of the curricula included all the ICM competencies [ 42 ]. In Nigeria, of the2 institutions in the 3 selected northern states providing pre-service education for midwives, 23 competencies were found not to align with the ICM standards [ 43 ]. Similarly, in Uganda, wide disparities were noticeable in curricula compared to the ICM standards, midwives synonymous with general nurses working in the maternity unit because graduates lack competencies in the midwifery mode of professional care [ 44 ].

In an undergraduate midwifery programme in South Africa, the content of the curriculum revealed that some topics were integrated into the existing curriculum using CBE approaches. For instance, a study showed that the competency-based course materials on Prevention of Mother to Child Transmission (PMTCT) of HIV/AIDS were adequate, and that the course was found to be sustainable for undergraduate midwifery students [ 45 ]. In a similar study, PMTCT including HIV and AIDS related outcomes was recommended to be fully integrated into classroom teaching and at SDP (Service Delivery Points) for nursing and midwifery competencies, including assessment strategies [ 46 , 47 ]. This study concludes that incorporation of the Nurse Initiated Management of Anti-Retroviral Treatment (NIMART) course into the undergraduate nursing programme was supported by nurse educators who expressed that the NIMART course will benefit the student nurses, the NEIs and the communities at large [ 48 ]. The Simulation Learning Package (SLP) on PPH (Post-Partum Hemorrhage) developed for undergraduate midwifery students was also found suitable [ 49 ]. In South Africa, a competency-based Curriculum Framework was found to be necessary and was developed to standardize genetics education in an Advanced Midwifery Programme [ 50 ]. In Tanzania and Uganda, Training Resource Packages (TRPs) to Strengthen Pre-service Family Planning Training for Nurses and Midwives was integrated into the pre-service curriculum using CBE approaches [ 51 ]. In Kenya, in 2021, the Nursing Council of Kenya (NCK) in collaboration with the Liverpool School of Tropical Medicine (LSTM) and multiple stakeholders reviewed and updated the nursing and midwifery degree programme focusing on strengthening the quality of training of the pre-service faculty and clinical instructors on pedagogy skills and capacity-building for the provision of competency-based Emergency Obstetrics and Newborn Care (EmONC) [ 52 ]. The study established that the curriculum component concerning the active management of the third stage of labour aspect in the curriculum was adequate [ 53 ].

Theme 2: The CBE curriculum implementation process generated five (5) sub-themes which are (a) contextual factors for curriculum reform (b) stakeholders’ engagement (c) roles of stakeholders. (d) opinion of stakeholders on CBE (e) development of intervention tool informing the model /framework

Sub-theme 1: contextual factors for curriculum reform.

This review identified the contextual factors for curriculum reform in various countries. The most prominent factor for the transition to CBE was the need to prepare competent midwives through the improvement of the quality of pre-service midwifery education to address the high burden of maternal and newborn mortality, especially in Africa, where the rates are high [ 52 , 54 , 55 ]. In South Africa and Rwanda, curriculum reform was borne from a demand for competent graduates, the political agenda of the countries to respond to population health, the transformation of higher education, the health care systems and undergraduate nursing education [ 56 , 57 ].

Sub-theme 2: Stakeholders’ engagement

The stakeholders identified are policy makers (national governments), ministries of health, ministries of education, professional regulatory bodies of the countries, commissions for the universities, institution administrators, heads of nursing and midwifery programmes, faculties (which include nurse and midwifery educators, clinical instructors and clinical staff, clinical supervisors and clinical preceptors), students’ interprofessional collaborations and partnerships [ 56 , 58 , 59 , 60 ]. In Ethiopia, the stakeholders involved in the midwifery curriculum process were primarily education experts with minimal contributions from professional bodies, classroom educators and clinical preceptors, which reflected in the content lacking midwifery clinical practice [ 51 ]. While it was evident that the curricula in Ghana and Malawi received input from their professional bodies since the content comprised information on midwifery clinical practice [ 61 ]. A part of highlighting effective curriculum development processes is a focus on interprofessional collaborations within and between universities, both local and international partnerships [ 52 , 58 , 62 , 63 ]. For instance, in Kenya, the Nursing Council of Kenya (NCK), in collaboration with an international body developed a competency-based curriculum integrating EMNOC [ 64 ]. In 2012, the Global Nurse Capacity Building Programme (GNCBP) through the Nursing Education Partnership Initiative (NEPI), was instrumental in the development of the maiden competency-based curriculum (CBC) for the post-basic Diploma in Midwifery programme in Lesotho, across all of the Nursing Education Institutions (NEIs) [ 65 ]. The NEPI further collaborated and partnered with nursing and midwifery education institutions and national health departments in other African countries such as the Democratic Republic of Congo, Ethiopia, Lesotho, Malawi, South Africa, and Zambia [ 63 ]. An exploration of nursing students’ experiences and perceptions at the school of nursing sciences in South Africa (SA) revealed that students recommended the need for inter- and intra- collaborative partnerships between professionals in the universities and clinical practice settings [ 66 ].

Sub-theme 3: Roles of the stakeholders in curriculum process

Implementation of competency-based education requires engaging all stakeholders so that they discharge their roles in the review, development and adoption of a CBE curriculum to create a national standard for teaching and learning in a particular country [ 55 , 63 , 64 ]. The government of the country is expected to exert its political will by making the implementation of the curriculum a policy, and ensuring compliance by all stakeholders/policy makers. Governments are expected to provide an enabling environment through capacity-building of faculties and provision of financial, human and material resources for the proper implementation of CBE [ 58 , 62 ]. The role of regulatory bodies, which include professional bodies and university commissions, is to ensure that schools adopt and adapt the curriculum. With support from government and partners, Stakeholders/policy makers t should facilitate the training and retraining of faculties and distribute supplies and resources for the implementation of CBE [ 58 , 62 ]. Stakeholders/policy makers should also monitor and evaluate the curriculum through consultation with other stakeholders to update the curriculum regularly [ 59 ]. The role of faculties is to adopt and integrate the CBE into the teaching and learning of students, maximizing the available support, and being committed to in-service training/retraining on CBE, including that of new faculties [ 67 ]. The students provide feedback on the CBE curriculum [ 66 , 68 ].

Sub-theme 4: Opinions of stakeholders regarding CBE

The study assessed the readiness to adopt, appropriateness, feasibility and practicability, fidelity, implementation, attitude, perception, positive attitude, satisfaction, adequacy, suitability, acceptability to elicit the opinions of stakeholders on CBE. For example, in South Africa, the nurse educators showed a readiness to adopt technology-based education when asked, and participants showed a willingness to adopt it [ 69 ]. The findings in another study in South Africa confirmed that nurse educators were ready to use technology-based education (High Fidelity Simulation (HFS) but stressed that readiness does not translate to the utilization of HFS [ 70 ], while a further study found that institutions were moderately prepared to integrate simulation-based education into teaching and learning [ 71 ]. Educators established the appropriateness, feasibility, and practicability of integrating HIV/Aids into the nursing curriculum [ 47 ]. The suitability of the pedagogical approaches in CBE were explored and the study confirmed the suitability of the approach for training of nurses and midwives [ 72 ]. The appropriateness of the curriculum content was assessed for clarity, relevance, and suitability in preparing competent midwives. The findings showed that it was appropriate across all the variables of assessment [ 73 ]. While in Rwanda, findings revealed that nurses/midwife educators had good knowledge which was evident in their mastery and utilization of different teaching strategies in a CBE approach and a positive perception toward effective implementation of CBE [ 74 ].

The educators acknowledged the positive influence of IT in nursing education and showed a good attitude toward IT use [ 75 ] (Singh and Masango, 2020). A study concluded that nurse educators perceived the incorporation of the NIMART course into the undergraduate nursing programme as a good idea and approved its incorporation [ 48 ]. A study on the fidelity of implementing the Community-Based Nursing Education (CBNE) programme during the COVID-19 pandemic found that the nurse educators satisfactorily maintained the fidelity of implementing the CBNE framework within the context of COVID-19 [ 76 ]. In Uganda, the implementation of CBE by educators in institutions was explored, and the literature indicated that the CBE curriculum had been analytically planned and implemented, which was evident in major similarities amongst institutions in the country [ 77 ]. Study results highlighted that nurse educators in KwaZulu-Natal have positive attitudes toward utilizing technology to support teaching and learning, provided that the technology is readily accessible [ 78 ].

Other studies assessed students’ opinions on CBE implementation. A study conducted on case-based learning (CBL) showed that students had positive perceptions of and supported CBL, while they highlighted the importance of group dynamics as a key success factor to successful implementation [ 79 ]. Concerning Problem-Based learning (PBL), the majority of the students had a positive perception of PBL, with a few students feeling confident in utilizing most of the PBL processes [ 80 ]. In this experimental study, students who participated found simulation method more satisfactory than students who did not participate [ 81 ]. In a study by Gudayu, it was discovered that students’ satisfaction and confidence was average in the use of simulation among midwifery students [ 82 ]. In South Africa, students expressed that educator supported the use of creative pedagogical approaches but would appreciate further training and support to equip them to use and gain mastery of a range of creative teaching strategies [ 67 ].

Sub-theme 5: Development of a framework/model/theory

The development of the model or framework was identified as critical for CBE curriculum implementation. In Lesotho, following two years of integration of CBE, implementers had difficulty implementing and sustaining CBE. This called development of an evidenced-based framework to direct the implementation and sustainability of a competency-based curriculum for higher education in midwifery [ 83 ]. An integration model for including HIV and AIDS into the nursing curriculum was developed by Modeste [ 84 ]. The model proved useful in enhancing the competencies of nurses in the provision of HIV and AIDS-related care and management [ 84 ]. A framework was developed to enhance the incorporation of simulation in nursing education and the development of clinical competence in a low resource setting [ 85 , 86 ]. A model to facilitate transformative learning in nursing education was developed and found to be adaptable to all settings of clinical practice, research, and education [ 87 ]. Phaladi-Digamela (2015) developed a curriculum framework to standardize genetics’ education in the advanced midwifery programme [ 50 ]. Rakhudu and colleagues developed a model of collaboration to implement PBL in nursing education [ 66 ]. In Rwanda, a middle-range theory was developed to guide the implementation of a competency-based curriculum in pre-service nursing education [ 88 ]. A framework to guide the assessment of clinical competence and to track student clinical experience in neonatal nursing clinical teaching was developed [ 89 ].

Theme 3: Pedagogical approaches in CBE

The pedagogical approaches identified in CBE include the use of IT in nursing education [ 75 ] and other forms of IT, such as e-learning [ 90 , 91 ] and nursing and midwifery informatics [ 92 ]. Educational board games [ 93 ], narrative case studies [ 94 ], value clarification through ‘Difficult Dialogues’ strategies [ 95 ] are also some of the approaches discussed including technology-based education [ 69 , 78 ] such as Simulation Based-Learning [ 81 , 82 , 96 ] and High-Fidelity Simulation [ 70 ]. Other approaches mentioned are case-based learning which includes group work, reflection, and student presentation [ 79 , 97 ] and problem-based learning [ 66 , 80 , 98 , 100 ], as well as direct observation of procedural skills as an appropriate tool to assess student clinical competence [ 101 ]. The OSCE method was mentioned as a popular assessment tool to evaluate the clinical competence of students [ 102 , 103 ].

Theme 4: benefits of CBE

Some of the literature reviewed expressed the outcomes of CBE as including educators’ increased competencies and confidence in teaching [ 52 , 64 , 104 ]. The literature further revealed that orientation on all teaching strategies increased knowledge, thus informing the importance of using a variety of teaching strategies by faculties [ 105 ]. A study on the value clarification process concerning abortion-related services in South Africa reports that CBE promotes transformative learning and improves intellectual growth among learners [ 95 ]. Midwifery educators described their experiences with the OSCE development process as an exercise that equips them with leadership skills and knowledge which is critical to the midwifery practice and education [ 102 ]. The use of educational board games was found to be cost-effective and to assist in translating knowledge to care provision [ 93 ]. The results of a study on PMTCT competency-based course materials showed that it promotes higher-order thinking, improves communication skills, teamwork and learning among students [ 98 ]. A study on High Fidelity Simulation infers that it promotes experiential and contextual learning, encourages self-directed learning and reflective learning [ 99 , 106 ]. These findings further confirm that Simulation-Based Learning develops student skills and confidence to manage complex real-life emergencies because it offers an opportunity for learners to be immersed in an environment that is closer to reality [ 96 ]. Problem-based learning through simulation also promotes teamwork among students and the ability to render holistic nursing care to patients [ 100 ]. The developed simulation learning package (SLP) on PPH was found suitable for undergraduate nursing students, as it also encourages active learning, collaboration, and multiple teaching techniques, feedback, critical thinking, self-confidence, and satisfaction [ 49 ].

Theme 5: Sustainability of CBE curriculum

Only two literature sources categorically discussed the sustainability of CBE [ 83 , 107 ]. Other literature sources report on the issues challenging the implementation of CBE. In Lesotho, inadequate support and monitoring of a newly implemented CBC within the midwifery programme threatened its sustainability among NEIs in the country [ 59 ]. In the Democratic Republic of Congo, despite CBE being widely promoted by the Ministry of Public Health, an insufficient budget and inadequate educators trained in CBA methodology were highlighted as major factors accounting for the continued use of the traditional approach (Ministry of Public Health [ 108 ]. The same was reported for Morocco and South Africa despite the necessary support and training in CBE, implementers continue to implement TBA such as the lecture method and demonstration in teaching across all subject areas [ 55 , 67 ].

Theme 6: facilitators of CBE implementation

Sub-theme 1: broad stakeholder support.

Much Emphasis is placed on broad stakeholder support both locally (local capacity building) and internationally, which should be intentional and sustained for longer periods. Broad stakeholder support has been stressed as an important facilitator to CBE implementation. This includes governmental support of the nursing and midwifery council through capacity building of faculties and supply of equipment [ 70 , 91 ] as well as established and functional interprofessional collaborations, both locally and internationally [ 91 , 109 ]. Students also need adequate educator support in terms of being exposed to more practical sessions, as such practices boost competency, satisfaction, and confidence [ 53 , 82 ].

Sub-theme 2: Functional monitoring system:

A functional monitoring system was identified as a notable facilitator which involves extensive coordination among all stakeholders to promote strong ownership and acceptability of the CBE project [ 91 ]. This study found that poor support and a weak monitoring system, especially in relation to professional regulatory councils, jeopardizes CBC sustainability. The previous literature on sustaining the implementation of a competency -based midwifery programme revealed a lack of accountability for the new curriculum from implementers during classroom teaching, throughout the programme. This was traceable to the lack of expertise of the educators which resulted in them returning to the traditional method [ 107 ].

Sub-theme 3: Availability of Guidelines Informing the Frameworks /Models

The availability of guidelines that inform frameworks or models that communicate nationally or globally, is recognised as a facilitator to the implementation and sustainability of CBE [ 107 ]. A framework for implementing and sustaining a competency-based curriculum was developed in Lesotho to serve as guide [ 83 ].

Sub-theme 4: Motivation and Recognition:

The need for motivated staff students, tutors and other stakeholders was also mentioned to sustain the enthusiasm and interest for CBE programme implementation [ 91 , 109 ]. Further factors are the awareness that midwives are able to deliver quality midwifery care if educated and motivated, and women’s demand for quality maternity care from highly competent and motivated midwives [ 109 ].

Theme 7: Challenges Concerning the Implementation of CBE

Sub-theme 1: poor knowledge of cbe.

The findings showed that educators and clinical preceptors involved in the training and clinical facilitations have sub-optimal knowledge of active learning methods of the various pedagogical approaches which have been identified for implementing CBE which inevitably challenges the proper implementation of a nursing and midwifery CBE curriculum [ 97 , 110 ]. In Tanzania, educators were unable to deliver the prescribed allocations of the nursing and midwifery CBET curriculum due to poor understanding and interpretation of the CBC [ 111 ]. In Ethiopia, the majority of the classroom educators and clinical preceptors had low teaching competency in CBE especially in relation to student-centered learning, e-learning and gender studies [ 112 ]. In another study, both staff and clinical preceptors reported that they were poorly oriented regarding the implementation of a competency-based curriculum in supervision and evaluation of midwifery students [ 61 ]. Some educators claimed they were unfamiliar with the Problem-Based Learning (PBL) approach [ 98 ]. In a study on integrating a Training Package for Family Planning using competency-based teaching methods into their curricula, the educators from nursing and midwifery training institutions were unable to integrate the training packages successfully, because they were not familiar with the incorporation process for such approaches [ 51 ]. In a study conducted by Milly and others, the stakeholders within and NEIs had challenges integrating CBE into teaching and learning which was reflected in the wide disparities in implementation of curriculum content/subject areas in the various institutions [ 73 ].

Sub-theme 2: Inadequate Human and Material Resources

Other major challenges in institutionalizing CBE were reported to be human resources, financial, and material constraints [ 72 , 73 , 77 , 113 ]. The facilitation of the training of these students requires a well- resourced clinical environment with essential medical supplies, a conducive environment, adequate faculty members for effective guidance and supervision and feedback to the students are often grossly insufficient [ 100 , 103 ]. In Lesotho, over-dependence on improvision of equipment and supplies during simulation, some faulty high-fidelity simulators and inadequate staffing impacted negatively on the successful implementation of SBE [ 114 ]. In a study on the integration of NIMART into the curriculum, it was discovered that state policies on distribution of antiretroviral commodities limited the availability of antiretrovirals, thus hampering the opportunities for students to learn the practice of PMTCT competently [ 46 ], while others found the course content to be inadequate with the tutors not adequately prepared which constituted a notable challenge [ 92 ]. Another study observed that regarding the CBE approaches that require the use of the internet, such as PBL, e-learning, participants reported resources in the library and computer laboratories, internet connectivity, insufficient training, qualifications of the faculty and class sizes to be inadequate [ 75 , 98 ]. The persistent shortage of qualified staff and competent clinical preceptors in the clinical settings, coupled with the lack of teaching and training resources and increased workload impacted on the quality of midwifery education [ 61 , 111 , 115 , 116 ]. Students often need to contend with the demand for clinical experience as the midwifery student population continues to increase, exceeding the institutional capacity [ 51 , 105 ].

Sub-theme 3: Lack of Motivation and Support

Lack of continuous support in using the different teaching approaches was highlighted among the challenges in implementing CBE. Nursing/midwifery educators reported that using active teaching strategies contributes to an increased workload, hence the need for continuous support [ 74 ]. Students reported that insufficient support was largely due to shortage of staff as they lacked an adequate number of tutors and clinical supervisor/preceptors, and the competent clinical preceptors necessary to support clinical and theoretical learning [ 72 , 98 ]. Students further expressed a need for support in terms of constructive criticism, for educators to be patient, and correct them respectfully, as well as easy access to the simulation lab [ 114 ]. Proper implementation of CBE requires staff to be motivated; availability of funds and managerial/administrative support [ 71 ]. Staff should be supported to attain higher educational levels; teaching materials and good working conditions should be provided [ 109 ].

Sub-theme 4: Insufficient time

Insufficient time was noted by educators and students as being another major challenge [ 97 , 111 ]. The educators experienced problems integrating the TRP content using CBE to include it in the family planning curriculum because the time available was insufficient, even before training began [ 51 ]. Students complained about time constraints as a challenge, since they feel pressured by the timing for delivery combined with the increased workload experienced with the implementation of CBE [ 97 , 98 ]. In another study, students stated that a great amount of content in the curriculum was not covered because the curriculum was too heavily loaded and the time allocated was insufficient [ 115 ]. Insufficient hours being allotted for clinical training and teaching was another factor mentioned [ 114 ].

Sub-theme 5: Poor Accountability

Results showed that students lacked accountability for their learning and were disinterested in engaging in critical thinking [ 97 ], Studies revealed that students lacked the prerequisite knowledge for their studies [ 109 ].

This study showed that of the 54 African countries according to the World Bank classification, the literature on CBE for midwifery programmes only spanned 17 African countries at the time of this report. South Africa, Rwanda, Tanzania, Uganda, Lesotho, Kenya, Egypt, Malawi, Democratic Republic of Congo Morocco, and Zambia were among the countries implementing CBE. However, in Botswana, Problem-based learning was integrated into its curriculum with little success recorded following the implementation. Needless to say, where CBE was claimed to be implemented, the implementation appeared questionable. This may also imply that there is limited support for the proper implementation of CBE where it is practiced, for example, in the Democratic Republic of Congo, CBE has been widely promoted by the Ministry of Public Health, yet 81% of the country’s nursing education institutions continue to use a traditional approach due to an insufficient budget and a paucity of educators trained in the competency-based approach [ 108 ]. In Lesotho, wide disparities exist in the implementation of the CBC within the midwifery programme among NEIs in Lesotho. The major components of the Competency-based midwifery programme were not fully adopted to assimilate CBE [ 59 ]. Despite the adoption of CBE since 2013 with support for implementation in Morocco, TBA continues to be the mainstay for teaching and learning [ 55 ]. These findings are similar to those of other studies which reported inconsistences in the type and nature of midwifery education despite ICM standards [ 117 ].

The findings showed that the content of the curriculum differs appreciably from ICM standards among training institutions within the various nations, while new topics integrated into existing curricula employed CBE approaches These findings build on existing evidence showing that discrepancies in the nature and content of midwifery education programmes prevail globally [ 14 , 16 , 20 ]. The integration of new topics using CBE approaches may suggest that faculties need more training on the various CBE approaches It could also denote that the appropriate pedagogical approach(es) for each topic/course should be properly integrated so that instructional design aligns with the competency-based curriculum to ensure utilization and accountability.

This review revealed that for successful implementation of CBE, the following CBE curriculum implementation process must be strictly observed: identify contextual factors for curriculum reform, stakeholders’ engagement, roles of stakeholders, opinion of stakeholders of CBE and the development of intervention tools to informs the model /framework. The identified contextual factors in this review include the need for competent midwifery graduates to provide high-quality sexual and reproductive health care to combat SDG-3 goals in reducing the high burden of maternal and newborn mortality, especially in Africa, where the burden is alarming [52,54,55,]. Other factors are the transformation of higher education, the health care system and undergraduate nursing education programmes [ 56 , 57 ]. This suggests that countries should critically self-examine and analyze themselves to justify the need for curriculum reform. This will serve as a motivator for planning curriculum reform, implementation, and sustainability across nations. This concurs well with similar studies on curriculum reform conducted in the United States [ 118 , 119 ]. The study highlighted broad stakeholders’ involvement in the CBE implementation process and, while this is commendable, the engagement of stakeholders is presently grossly inconsistent. For example, in Tanzania, multiple stakeholders include the Tanzanian commission comprised of university, faculty, interprofessional collaborations and international partners. In Ethiopia, education experts were mainly involved in the CBE curriculum process. In Ghana and Malawi, professional organizations were the major contributors. This review further showed the relevance of identified stakeholders in the curriculum planning and implementation process by highlighting their roles and involvement in the success of the CBE implementation. This report is similar to findings from previous authors on stakeholders’ involvement in the implementation of curriculum [ 120 , 121 , 122 ]. Also, the development of an intervention tool which informs the model /framework will serve as a guide and a national template for implementers enabling them the maintenance of standards. This conforms with findings from study conducted by Dragoo and colleague on Implementing competency-based education [ 123 ]. It is hoped that proper adherence to the curriculum implementation process will promote accountability and acceptability of CBE for all stakeholders.

The study highlighted the numerous pedagogical approaches employed in the implementation of CBE. This implies that multiple approaches should be utilized in the teaching and training of midwifery students so that the approaches complement one another to achieve the best result. This is consistent with similar study on CBE [ 72 ]. All stakeholders should be cognizant and trained to utilize the various teaching methodologies, while a functioning system should be put in place to ensure accountability and sustainability of all pedagogical approaches [ 118 ]. The study revealed that the implementation of CBE offers several benefits to students, faculties, nations and the communities it serves. Hence its implementation should be widely encouraged and supported by all stakeholders to prepare competent midwifery students. This finding is in agreement with another study where the benefits of CBE were mentioned [ 118 ].

There is a paucity of literature on the sustainability of CBE, however most of the literature reported challenges with the implementation of CBE. Evidence from the literature confirmed that CBE has not been sustained in Africa. It remains a struggle to fully integrate the major components of the Competency-based midwifery programme due to inadequate support and lack of a monitoring system which challenges its implementation and sustainability.

Much emphasis has been placed on broad stakeholder support, both locally (local capacity building) and internationally, which should be intentional and sustained for longer periods. A functioning monitoring system, the availability of guidelines informing frameworks or models, adequate supervision and support for students coupled with a highly motivated and educated faculty, clinical staff, students, and other stakeholders are requirements [ 91 ]. The awareness that women demand quality maternity services from competent and highly educated midwives, and thus that the planned CBE programme is appealing and interesting was highlighted [ 109 ].

Poor knowledge of the various pedagogical approaches for implementing CBE was reported by implementers as jeopardizing the proper implementation of the nursing and midwifery CBE curriculum. Other major challenges identified in implementing and sustaining CBE were inadequate human resources, both in quality and quantity and financial and material constraints. Participants complained of insufficient time being allocated for teaching and learning, high workloads and a shortage of educators [ 111 ], while lack of motivation and support, and poor accountability on the part of the student were also cited. This finding is in line with previous authors on challenges on implementation of CBE [ 22 , 35 , 118 , 123 , 124 ].

Strengths and limitations

The study methodology involves a rigorous and contemporary search of the published literature on competency-based education for midwifery education and practice. The PRISMA-ScR extension guided this scoping review. The review was limited to studies conducted in the English language, however only three studies were found to be conducted in other languages (two in French, one in Arabic). The review included conference proceedings to obtain country representation on the subject area.

Competency-based education is a proven approach to preparing competent and confident graduates. The implementation and sustainability of CBE is just emerging in Africa. It is expedient that CBE implementation should be planned concurrently with its sustainability in order for it to be effective especially in Africa where resources are scarce.
