Summary and Conclusion (Chapter 2): A Complete Guide for Dissertations

What Is the Summary and Conclusion of Chapter Two?

The summary and conclusion is the final section of your literature review chapter. It serves two essential purposes:

1. Summary: It provides a concise recap of the major themes, findings, and insights from your review, reminding readers of the key points they should take away.
2. Conclusion: It closes the chapter by synthesizing what the literature has established, what gaps remain, and how your study will address those gaps, thereby transitioning to Chapter Three.

Think of this section as the bridge between your review of existing knowledge and your proposed contribution. It is not a place for introducing new literature or new ideas. It is a place for synthesis, closure, and forward-looking transition.

Why It Is Important

1. Provides Closure: It signals that the literature review is complete.
2. Reinforces Key Messages: It reminds readers of the most important takeaways.
3. Demonstrates Synthesis: It shows you can distill complex material into concise conclusions.
4. Connects to Your Study: It explicitly links the review to your research.
5. Justifies Your Research: By recapping gaps, it reinforces why your study is needed.
6. Transitions to Methodology: It prepares readers for Chapter Three.

How to Write It (Step-by-Step)

Step 1: Restate the Purpose

Begin by briefly reminding readers why you conducted this review and what it aimed to accomplish.

Step 2: Recap Each Major Theme

For each major section (historical, theoretical, empirical, methodological), provide a concise summary of key points. Use one to two sentences per theme.

Step 3: Summarize Key Findings

Distill the most important conclusions that emerge from the body of research. What can we confidently claim?

Step 4: Recap Major Gaps

Briefly remind readers of the most significant gaps or limitations you identified.

Step 5: Explain How Your Study Addresses These Gaps

Explicitly connect the gaps to your own research. Show how your study is designed to address these limitations.

Step 6: Present Your Research Questions or Hypotheses

Present them clearly in a numbered or bulleted list. This provides a formal transition from what is known to what your study will investigate.

Step 7: Transition to Chapter Three

End with a sentence that leads readers into your methodology chapter: "Chapter Three presents the methodology designed to answer these research questions."

Common Mistakes to Avoid

1. Introducing New Literature: Only reference literature already discussed. No new citations.
2. Simply Repeating Thematic Summaries: Synthesize across themes, don't just copy topic sentences.
3. No Connection to Your Study: Always explain how the review relates to your research.
4. No Research Questions: Always formally state what your study will investigate.
5. Too Long: Keep to 2–4 pages. Distill, do not expand.
6. Too Short: Provide enough detail to remind readers of key points.
7. No Transition to Next Chapter: End with explicit transition to methodology.
8. Vague Language: Be specific about findings and gaps.
9. Apologetic Tone: Be confident. "These gaps establish the need for the current study, which addresses them through..."

Quick Checklist

• Does it begin with a brief restatement of the literature review's purpose?
• Does it concisely recap each major theme or section?
• Does it summarize key findings across the literature?
• Does it recap the most significant gaps or limitations?
• Does it explicitly explain how your study addresses these gaps?
• Does it present your research questions or hypotheses clearly?
• Does it end with a transition to Chapter Three?
• Is it concise (typically 2–4 pages)?
• Does it avoid introducing new literature?
• Does it synthesize rather than simply repeat?

Summary

The summary and conclusion of Chapter Two is the bridge between your review of existing knowledge and your proposed contribution. It provides closure for the literature review while pointing forward to your methodology.

A strong summary and conclusion restates purpose, concisely recaps themes, summarizes key findings, recaps gaps, explains how your study addresses them, presents research questions clearly, transitions to Chapter Three, and is concise but comprehensive.

When written effectively, it ensures readers understand the state of knowledge in your field, the gaps that remain, and exactly how your study will contribute.
