Introduction

The literature review is one of the most important chapters of a dissertation, thesis, or research project. It demonstrates your understanding of existing research, identifies gaps in current knowledge, and explains how your study contributes to the academic conversation.

Students at the National University of Singapore (NUS) complete literature reviews across a wide range of disciplines, including Business, Engineering, Computing, Data Science, Medicine, Public Health, Law, Education, Social Sciences, and many others. Because this chapter requires extensive reading, critical analysis, and academic writing, many postgraduate students find it one of the most challenging parts of the research process.

This guide explains how to write a high-quality literature review and how AssignmentCart provides ethical academic support to help NUS students improve the clarity and presentation of their own academic work.

What Is a Literature Review?

A literature review is a critical evaluation of existing academic research related to your chosen topic.

Rather than simply summarising studies, you should:

• Compare different viewpoints

• Analyse research findings

• Evaluate strengths and weaknesses

• Identify trends

• Highlight research gaps

• Justify the need for your own study

A strong literature review demonstrates that you understand the current state of research in your field.

Why Is the Literature Review Important?

Universities expect literature reviews to show that you have:

• Conducted comprehensive academic research

• Understood major theories

• Evaluated previous studies critically

• Identified unanswered questions

• Positioned your own research appropriately

This chapter provides the theoretical foundation for the rest of your dissertation.

Finding High-Quality Academic Sources

Use reliable and authoritative sources, including:

• Peer-reviewed journal articles

• Academic books

• Conference proceedings

• Government publications

• Professional organisations

• University library databases

Avoid relying on blogs, opinion websites, or unverified online sources for academic arguments.

Organise Your Literature Review

A well-structured literature review is easier for readers to follow.

A common structure includes:

Introduction

Explain:

• The topic

• Scope of the review

• Search strategy

• Organisation of the chapter

Main Discussion

Organise literature by:

• Themes

• Concepts

• Methodologies

• Chronology

• Theoretical perspectives

Each section should compare studies rather than describe them individually.

Research Gap

Identify:

• Unanswered questions

• Conflicting findings

• Methodological limitations

• Areas requiring further investigation

Clearly explain how your research addresses these gaps.

Summary

Conclude by summarising:

• Key findings from previous research

• Major themes

• Remaining gaps

• Connection to your own research objectives

Demonstrate Critical Analysis

High-scoring literature reviews focus on evaluation rather than description.

Discuss:

• Strengths of previous studies

• Weaknesses of existing evidence

• Differences between researchers

• Methodological limitations

• Practical implications

• Areas requiring future research

Critical thinking demonstrates postgraduate-level academic ability.

Use the Correct Referencing Style

NUS faculties may require different referencing styles depending on the programme.

Common styles include:

• APA 7th Edition

• Harvard

• IEEE

• Chicago

• MLA

Ensure:

• All in-text citations are included.

• Reference lists are complete.

• Formatting remains consistent.

Always follow your department's official dissertation guidelines.

Common Literature Review Mistakes

Students frequently lose marks because they:

• Summarise instead of analyse

• Use outdated research

• Include unreliable sources

• Lack logical structure

• Ignore research gaps

• Have inconsistent referencing

• Repeat similar points

• Submit without proofreading

Avoiding these issues significantly improves the quality of your review.

Tips for Writing a Strong Literature Review

To improve your literature review:

• Search recent academic databases.

• Read widely before writing.

• Group studies into themes.

• Compare different viewpoints.

• Identify knowledge gaps.

• Maintain an objective academic tone.

• Proofread thoroughly before submission.

Good planning results in a stronger review.
