How to Synthesize Literature Instead of Just Summarizing It
Every Kenyan student remembers that moment—the day your lecturer announces it’s time to start your thesis proposal. The room goes quiet. Palms sweat. Questions race through your mind: Where do I even begin? What if my topic is rejected? How do I impress my supervisor?
Take a deep breath. Writing a thesis proposal is challenging, but it’s absolutely doable with the right roadmap. In fact, a well-written proposal is 80% of the battle. Once your proposal is approved, the actual thesis writing becomes a matter of execution.
This guide will walk you through every step of writing a thesis proposal in Kenya. Whether you’re an undergraduate at the University of Nairobi, a master’s student at Kenyatta University, or a PhD candidate at Moi University, the principles are the same. By the end, you’ll have a clear roadmap to write a proposal that impresses your supervisor and sets you up for research success.
What Is the Difference Between Summarizing and Synthesizing?
Definition of Summarizing
Summarizing means describing one source at a time. You read a paper, extract its main argument, and write it down. Then you move to the next paper and do the same thing. The structure looks like this:
“Author A (2020) found that X influences Y. Author B (2021) studied the same topic and found Z. Author C (2022) reported that W is also important.”
This is factual reporting. It’s not wrong, but it’s also not impressive.
Definition of Synthesizing
Synthesizing means combining multiple sources to create new insights. You identify patterns, agreements, disagreements, and gaps across the literature. The structure looks like this:
“Several studies have found that X influences Y (Author A, 2020; Author B, 2021). However, this relationship is contested. Author C (2022) found no significant relationship, suggesting that contextual factors may play a role. Taken together, these studies indicate that while X appears relevant, the conditions under which it operates remain unclear.”
Notice the difference? Synthesis tells a story about the state of knowledge, not just a list of what individual authors said.
Side-by-Side Comparison
| Aspect | Summarizing | Synthesizing |
|---|---|---|
| Purpose | Report what each source said | Identify patterns and insights across sources |
| Structure | Source-by-source | Theme-by-theme |
| Language | “According to…” “Author A found…” | “Similarly…” “In contrast…” “Taken together…” |
| Your voice | Absent | Present (evaluation, connection, conclusion) |
| Outcome | Annotated bibliography | Coherent argument |
Why Synthesis Matters in Your Thesis Proposal
Your literature review isn’t just a box to check. It serves three critical purposes:
It demonstrates you understand your field. Supervisors want evidence that you’ve engaged critically with existing research, not just skimmed it.
It builds a case for your research gap. By showing what is known, what is disputed, and what is missing, you logically justify why your study is necessary.
It impresses your examiners. A synthesized literature review signals that you’re thinking at the required academic level. A summary-based review signals the opposite.
The Anatomy of a Weak Literature Review (Summarizing Only)
What a “Summary-Only” Literature Review Looks Like
Here’s an example of weak, summary-only writing:
“According to Otieno (2021), e-learning adoption in Kenyan universities has increased significantly since 2020. Wanjiku (2022) studied student attitudes toward online learning and found that most students prefer blended learning. Mwangi (2020) examined infrastructure challenges and identified unreliable internet as a major barrier. Kamau (2023) surveyed 200 students and reported that lack of devices affects engagement. These studies show that e-learning is important.”
Common Signs You’re Summarizing
You start every paragraph with an author’s name
You use “According to…” repeatedly
Your paragraphs describe one source, then move to the next source
There are no transition words showing relationships between sources
You end paragraphs without drawing conclusions
Why Supervisors Reject Summary-Based Literature Reviews
Summary-based reviews don’t demonstrate understanding. They show you can report but not think. Your supervisor will wonder: Do you understand how these studies relate to each other? Can you identify contradictions? Do you know what’s missing?
Without synthesis, you also fail to justify your research gap. If you’ve only summarized, you haven’t built an argument for why your study matters.
The Anatomy of a Strong Literature Review (Synthesis)
What a Synthesis-Based Literature Review Looks Like
Now here’s a synthesized version of the same sources:
“A growing body of research confirms that e-learning adoption in Kenyan universities has accelerated since 2020 (Otieno, 2021; Wanjiku, 2022). However, studies diverge on the primary barriers to effective implementation. While Mwangi (2020) identifies unreliable internet infrastructure as the dominant challenge, Kamau (2023) argues that device accessibility plays a more significant role in determining student engagement. This disagreement suggests that the relative importance of infrastructure versus access may vary by institutional context. What remains unexplored is how these factors interact with student digital literacy levels—a gap this study will address.”
Features of Strong Synthesis
Organizes sources thematically, not by author
Uses comparison language (similarly, in contrast, however)
Groups agreeing and disagreeing sources together
Identifies patterns, trends, and debates
Concludes each paragraph with a point about the state of knowledge
How Synthesis Connects to Your Research Gap
Notice how the synthesized paragraph ends by identifying what remains unknown. That’s the bridge from your literature review to your research objectives. Synthesis doesn’t just summarize the past—it builds the case for your future contribution.
A Step-by-Step Framework for Synthesizing Literature
Step 1: Read with a Purpose
Before you read a single paper, ask yourself: What question am I trying to answer? For a literature review, your guiding question might be: What does existing research say about my topic, and where are the gaps?
Write this question down. Keep it visible as you read.
Step 2: Create a Synthesis Matrix
A synthesis matrix is a simple table that helps you organize sources by theme rather than by author.
| Source | Theme 1: Definition | Theme 2: Causes | Theme 3: Effects | Theme 4: Contradictions |
|---|---|---|---|---|
| Otieno (2021) | Defines e-learning as… | Infrastructure as key | Positive on access | None noted |
| Wanjiku (2022) | Broader definition includes… | Attitudes equally important | Mixed effects | Disagrees with Otieno on access |
| Mwangi (2020) | Focuses on technical definition | Infrastructure only | Negative without support | Challenges both above |
| Kamau (2023) | Student-centered definition | Devices and skills | Depends on context | Finds Otieno too optimistic |
As you read each source, add its contribution to each relevant theme. By the time you’ve read 20 sources, you’ll see patterns emerge.
Step 3: Identify Themes and Patterns
Review your completed synthesis matrix. Look for:
Agreements: Which sources say similar things? Group them together.
Disagreements: Where do authors contradict each other? Note the debate.
Trends: How have findings changed over time? Earlier studies may differ from recent ones.
Gaps: What themes have few sources? What questions remain unanswered?
Step 4: Group Sources by Theme, Not Author
Now organize your literature review around themes, not authors. For example:
Theme 1: How researchers define your key concept
Theme 2: What studies agree on
Theme 3: Where studies disagree
Theme 4: What remains unknown
Each theme becomes a paragraph (or several paragraphs) in your literature review.
Step 5: Write Paragraphs Around Themes
Use this formula for each paragraph:
Topic Sentence → Evidence from multiple sources → Compare/Contrast → Your analytical point → Transition to next theme
Step 6: Add Your Critical Voice
Don’t just report what others said—evaluate it. Ask yourself:
Is this evidence convincing?
Are there methodological limitations?
Does this apply to my context (e.g., Kenya)?
Step 7: Conclude Each Section With a Gap Statement
Each thematic section should end by explaining how it connects to what remains unknown. This builds your argument incrementally.
Side-by-Side Examples: Summary vs. Synthesis
Example Topic: The impact of social media on student academic performance
The Summary Version (Weak):
“Johnson (2019) studied 200 university students and found that social media use during study time reduced test scores by 15%. Smith (2020) surveyed 150 students and reported that students who used social media for more than two hours daily had lower GPAs. Williams (2021) conducted interviews with 30 students and found that social media distracted them from assignments. Brown (2022) analyzed data from 500 students and confirmed a negative correlation between social media use and grades.”
The Synthesis Version (Strong):
“A consistent finding across multiple studies is the negative relationship between social media use and academic performance. In quantitative research, Johnson (2019) and Smith (2020) each reported significant grade reductions associated with high social media usage, with effect sizes ranging from 10-15%. Qualitative evidence from Williams (2021) supports these findings, as students consistently identified distraction as a primary mechanism. However, the magnitude of this effect is contested. While Johnson (2019) suggests any social media use during study time is problematic, Brown (2022) found that only usage exceeding two hours daily produced measurable effects. This discrepancy suggests that moderate use may be less harmful than previously assumed. What remains unexplored is whether intentional, curriculum-integrated social media use could produce different outcomes—a gap this study will address.”
What Changed?
| Summary Version | Synthesis Version |
|---|---|
| Lists authors one by one | Groups authors by theme (agreement, then disagreement) |
| No comparison language | Uses “however,” “supports,” “suggests” |
| No conclusion about the state of knowledge | Ends with a clear gap statement |
| No author’s voice | Adds evaluation (“contested,” “suggests”) |

Synthesis Checklist for Your Literature Review
Use this checklist to audit your own writing:
Does my paragraph start with a topic sentence about a theme, not an author?
Have I included evidence from multiple sources in each paragraph?
Have I used comparison/contrast language?
Have I shown both agreement and disagreement where relevant?
Have I added my own critical point about the evidence?
Does my paragraph end by advancing the argument toward my research gap?
Have I avoided starting multiple sentences with author names?
If you can answer “yes” to all seven questions, you’re synthesizing.
Frequently Asked Questions
Can I ever just summarize a single source?
Yes—for foundational or seminal works that deserve special attention. A single paragraph summarizing a key theory or landmark study is appropriate. The problem is when every paragraph does this.
How many sources should I include per paragraph?
Aim for 2-5 sources per paragraph in a typical literature review. The exact number matters less than the relationship you show between them.
What if only one source has studied my specific topic?
Then you’ve identified a genuine gap! Acknowledge the lone source, explain its limitations, and argue that more research is needed.
Is synthesis the same as critical analysis?
Not exactly. Synthesis is the organization of sources to show relationships. Critical analysis is your evaluation of those sources. A strong literature review does both.
Conclusion
Let’s return to where we started. That dreaded supervisor comment—“This is just summary. Where is your synthesis?”—is not a verdict on your ability. It’s a signal that you haven’t yet learned a specific skill. The good news is that synthesis is teachable. It follows a formula. And with practice, it becomes natural.
Remember the core distinction: Summarizing lists what authors said. Synthesizing tells a story about what the literature means.
Start with the synthesis matrix. Group your sources by theme. Use the sentence starters to show relationships. And always end your paragraphs by advancing the argument toward your research gap. Do this consistently, and your literature review will transform from a list of summaries into a compelling, critical argument that impresses your supervisor and justifies your research.
