HOW SINGAPORE EDUCATION WORKS · Synthesising Sources in University Writing
Find your next learning step
To synthesise sources, organise the paragraph around a question or claim, then explain how relevant sources relate to it. Compare what each source studied, what its evidence supports and where the findings differ. Keep the source's claim distinct from the conclusion you draw.

A sequence of accurate summaries can still leave the reader to do all the connecting work. Synthesis makes that connection visible without pretending that different studies measured the same thing.
This guide is for students moving from reading notes to an argument or literature discussion. Follow your assignment brief and citation rules. The source notes below are fictional teaching material, not published studies and not references you may cite as real research.
The choices at a glance
| What you notice | Possible issue | Useful next move |
|---|---|---|
| Sources appear one after another | The organising claim is missing | State what the paragraph is comparing |
| Similarly links different measurements | A relationship may be forced | Name the actual shared feature |
| Counts from unlike studies are pooled | The denominators describe different things | Keep datasets and outcomes distinct |
| A source becomes stronger in the paragraph | The interpretation outruns its evidence | Return to the original claim and limitation |

CHAPTER 1 OF 8 · Choose the paragraph's job and compare sources
1. Choose the question that will organise the paragraph
Begin with the paragraph's job. Are you comparing explanations, identifying a limitation, showing how methods affect findings, or explaining what remains unresolved?
“Three articles about university spaces” names a collection. “Do different study tasks call for different seating conditions?” gives you a question around which sources can be compared.
Read each source accurately before trying to combine it with others. Record the research question, setting, participants or materials, method, relevant result and limitation. Keep page numbers or other locations with the notes you may use.
The guide to academic reading helps with that first task. The guide to literature searching addresses finding material worth reading. Synthesis comes after those decisions; it does not replace them.
A paragraph needs a defensible purpose, not a target number of source names.
CHAPTER 2 OF 8 · Choose the paragraph's job and compare sources
2. Put sources beside shared questions
Create a small working grid with questions as columns and sources as rows. Useful questions might include: Which study task? What kind of evidence? Which setting? What conclusion is justified?
Leave a cell blank when a source does not answer that question. A blank is more honest than inventing a result to make the grid look complete.
Look for relationships with consequences. Two sources may support similar conclusions through different methods. They may appear to disagree because they study different groups, use different definitions or address different tasks.
Do not treat a difference in topic as a disagreement. A survey about individual reading and an interview about group planning can describe different needs without contradicting each other.
Purdue University's synthesis guidance discusses relationships among sources and cautions against forcing connections. The grid here is a suggested planning aid, not a required institutional template.
CHAPTER 3 OF 8 · Inspect a synthesis case and its numerical limits
3. A worked case: three fictional research notes
Assume a student has accurately extracted the following notes from three fictional sources supplied for a practice exercise. Treat their datasets as separate. No shared participants or comparable sampling method is established.
| Practice source | Evidence in the supplied note | What it directly describes |
|---|---|---|
| A | A survey: 14 of 20 respondents preferred a quiet setting for individual reading | Stated preference for one task |
| B | Interviews: 6 of 8 interviewees wanted conversation space for group planning | Reported need for another task |
| C | Observations: conversation occurred in 8 of 10 group-work sessions in a shared area | Observed activity in that setting |
A weak draft might say: “A discusses quiet reading. B discusses conversation. C discusses group work. Therefore, all students need the same kind of space.” The conclusion does not follow from the notes.
A stronger practice paragraph could say: “The supplied notes suggest that seating needs may depend on the study task. A records a preference for quiet during individual reading, whereas B reports a need for conversation during group planning. C's observations are consistent with conversation being part of some group-work activity, but do not establish what participants preferred. Together, these limited notes support considering more than one type of study space; they do not establish an effect on grades.”
The connection is task difference. The limitation is also explicit. The paragraph does not turn preference into measured learning improvement.
CHAPTER 4 OF 8 · Inspect a synthesis case and its numerical limits
4. Check the comparison before combining numbers
The fractions in the worked case are 14/20 = 70%, 6/8 = 75% and 8/10 = 80%. Calculating them correctly does not make them measurements of one common outcome.
Adding the numerators gives 28 and adding the denominators gives 38. The resulting fraction, about 73.7%, would not be a justified overall preference percentage. One denominator counts observed sessions, while the others count people answering different questions.
Likewise, saying “two out of three sources agree” may hide important differences in evidence. A source count alone does not tell you whether the claims are comparable or how much weight each deserves.
Write what the evidence actually permits: a preference in a particular survey, a reported need in interviews, or an observation in specified sessions. Then explain your qualified interpretation.
For real quantitative evidence synthesis, use the appropriate disciplinary methods and supervision. A thematic comparison in a coursework paragraph is not automatically a meta-analysis.
CHAPTER 5 OF 8 · Repair the argument and practise a comparison
5. Repair a paragraph that lists or overstates
If every sentence begins with a different author's name, inspect the organising idea. The pattern may be appropriate in some contexts, but ask whether the reader can see the comparison without reconstructing it.
If a linking word such as “similarly” joins sources measuring different things, name the exact similarity. Shared vocabulary does not by itself establish shared evidence.
If you claim that one source “proves” another wrong, compare their questions, definitions and methods. Different settings or tasks may explain the difference. If a real contradiction remains, preserve it rather than smoothing it away.
If a quotation does all the work, add your explanation of its relevance and limits. Use quotations only where needed, cite them accurately, and keep enough context to preserve the author's meaning.
If a source does not fit the paragraph's question, move it or leave it out for a stated reason. Do not distort it to keep an impressive citation in view.
If you are unsure whether your interpretation is fair, return to the source location and ask a specific question in a tutorial or consultation.
CHAPTER 6 OF 8 · Repair the argument and practise a comparison
6. Practise a claim and a counterclaim
For guided practice, use the fictional notes to assess this sentence: “Because 70% preferred quiet, universities should remove all conversation areas.” Identify both the evidence used and the jump in the recommendation.
Checking answer: the 70% comes from 14 of 20 respondents in A, concerning individual reading. It does not establish the needs of all students or all study tasks. B and C also provide reasons to consider conversation during group activity. The broad removal recommendation outruns the supplied evidence.
For independent practice, write a short comparison around this question: “Are the notes enough to claim that quiet spaces raise examination marks?” Use at least two relevant notes and make the uncertainty visible.
Checking answer: none of the notes measures examination marks. A and B concern stated preferences or needs; C records conversation. A defensible paragraph can explain why preferences matter to space planning while stating that an effect on marks remains untested here.
Next, write one sentence explaining a genuine difference between A and C. For example: “A records what respondents said they preferred for individual reading, whereas C records what happened during observed group sessions.” That difference prevents a false direct comparison.
In real coursework, replace the teaching labels with correct references to actual sources you have read. Do not cite these fictional notes as published evidence.
CHAPTER 7 OF 8 · Return later, transfer and answer questions
7. Return later and transfer the method
At a later writing session, put away the model paragraph. Rebuild its main claim from the three notes, then explain which conclusion the notes cannot support. This tests the reasoning rather than memory of the wording.
For changed-context practice, compare sources about another topic, such as whether museum labels help visitors find objects. Rebuild the comparison around that topic's questions and methods; do not carry over claims about quiet study.
A useful Singapore example is NUS CELC's SP2271 course description, which includes evaluating scientific sources and synthesising information among its objectives. That description concerns this particular course. It does not define every NUS assignment or every university's requirements.
The global connection is practical: researchers in different countries may use different settings and methods while addressing related questions. Explain those conditions so that an international comparison does not erase them.
Ask a peer to point to the paragraph's main claim, the supporting evidence and the limitation. The guide to peer review of university writing develops that feedback task further.
CHAPTER 8 OF 8 · Return later, transfer and answer questions
8. Common questions about synthesising sources
Must every paragraph use several sources?
No. A paragraph may need close analysis of one source or a different task altogether. Use the number and kind of sources required by the argument and assignment, not a universal quota.
Can sources disagree?
Yes. Explain the disagreement accurately and inspect its basis. A useful synthesis can show what remains unresolved rather than force a single answer.
Is paraphrasing the same as synthesis?
No. Paraphrasing changes how a particular source's meaning is expressed. Synthesis explains relationships among relevant source ideas and evidence. Accurate paraphrasing can be one part of it.
Does a comparison grid belong in the submitted essay?
Only if the brief or argument calls for it. A planning grid can help you reason without appearing in the final submission. Check your institution's expectations.
Can AI produce the synthesis for me?
Follow the course's rules about permitted assistance. Whatever tools are allowed, verify the actual sources and retain responsibility for the claims you submit. An unverified generated comparison can conceal invented references or altered findings.
