The majority of literature reviews follow a standard introduction-body-conclusion structure. Let’s look at the RRL structure in detail.
Introduction of Review of Related Literature: Sample
An introduction should clarify the study topic and the depth of the information to be delivered. It should also explain the types of sources used. If your lit. review is part of a larger research proposal or project, you can combine its introductory paragraph with the introduction of your paper.
Here is a sample introduction to an RRL about cyberbullying:
Bullying has troubled people since the beginning of time. However, with modern technological advancements, especially social media, bullying has evolved into cyberbullying. As a result, nowadays, teenagers and adults cannot flee their bullies, which makes them feel lonely and helpless. This literature review will examine recent studies on cyberbullying.
Sample Review of Related Literature Thesis
A thesis statement should include the central idea of your literature review and the primary supporting elements you discovered in the literature. Thesis statements are typically put at the end of the introductory paragraph.
Look at a sample thesis of a review of related literature:
This literature review shows that scholars have recently covered the issues of bullies’ motivation, the impact of bullying on victims and aggressors, common cyberbullying techniques, and victims’ coping strategies. However, there is still no agreement on the best practices to address cyberbullying.
Literature Review Body Paragraph Example
The main body of a literature review should provide an overview of the existing research on the issue. Body paragraphs should not just summarize each source but analyze them. You can organize your paragraphs with these 3 elements:
- Claim. Start with a topic sentence linked to your literature review purpose.
- Evidence. Cite relevant information from your chosen sources.
- Discussion. Explain how the cited data supports your claim.
Here’s a literature review body paragraph example:
Scholars have examined the link between the aggressor and the victim. Beran et al. (2007) state that students bullied online often become cyberbullies themselves. Faucher et al. (2014) confirm this with their findings: they discovered that male and female students began engaging in cyberbullying after being subject to bullying. Hence, one can conclude that being a victim of bullying increases one’s likelihood of becoming a cyberbully.
Review of Related Literature: Conclusion
A conclusion presents a general consensus on the topic. Depending on your literature review purpose, it might include the following:
- Introduction to further research. If you write a literature review as part of a larger research project, you can present your research question in your conclusion.
- Overview of theories. You can summarize critical theories and concepts to help your reader understand the topic better.
- Discussion of the gap. If you identified a research gap in the reviewed literature, your conclusion could explain why that gap is significant.
Check out a conclusion example that discusses a research gap:
There is extensive research into bullies’ motivation, the consequences of bullying for victims and aggressors, strategies for bullying, and coping with it. Yet, scholars still have not reached a consensus on what to consider the best practices to combat cyberbullying. This question is of great importance because of the significant adverse effects of cyberbullying on victims and bullies.
✍️ How to Write Review of Related Literature – Sample
Literature reviews can be organized in many ways depending on what you want to achieve with them. In this section, we will look at 3 examples of how you can write your RRL.
Thematic Literature Review
A thematic literature review is arranged around central themes or issues discussed in the sources. If you have identified some recurring themes in the literature, you can divide your RRL into sections that address various aspects of the topic. For example, if you examine studies on e-learning, you can distinguish such themes as the cost-effectiveness of online learning, the technologies used, and its effectiveness compared to traditional education.
Chronological Literature Review
A chronological literature review is a way to track the development of the topic over time. If you use this method, avoid merely listing and summarizing sources in chronological order. Instead, try to analyze the trends, turning moments, and critical debates that have shaped the field’s path. Also, you can give your interpretation of how and why specific advances occurred.
Methodological Literature Review
A methodological literature review differs from the preceding ones in that it usually doesn’t focus on the sources’ content. Instead, it is concerned with the research methods. So, if your references come from several disciplines or fields employing various research techniques, you can compare the findings and conclusions of different methodologies, for instance:
- empirical vs. theoretical studies;
- qualitative vs. quantitative research.
