Synthesis Writing
Group evidence by idea, compare source perspectives, and synthesize sources into a coherent line of reasoning.
A lesson of English 10, in Research and Synthesis, about 10 minutes.
By the end of this lesson, you will be able to synthesize information from multiple sources into a coherent argument, avoid patchwork writing, and use sources to advance your own position.
What Is Synthesis?
Synthesis is not summary and not collection. It is the active process of combining information from multiple sources to build a new argument.
The difference:
Summary: Source A says X. Source B says Y. Source C says Z.
Synthesis: While Source A and B both argue that X, Source C complicates this by showing Y — suggesting that the relationship between these variables is more conditional than it first appears.
In synthesis, the sources are in conversation with each other, and you are the one managing the conversation.
The Danger of Patchwork Writing
Patchwork writing is a sequence of quotations and summaries stitched together with minimal transition, creating the impression that the sources speak for themselves.
❌ "According to Smith, social media increases anxiety (52). Jones says teens use social media excessively (78). Williams notes that parents are concerned (90)."
This tells us what sources say. It does not build an argument.
Synthesis:
✓ "The research consistently finds a correlation between social media use and teen anxiety (Smith 52; Jones 78), though the mechanism remains disputed. While Smith attributes the effect to social comparison, Jones points to sleep disruption — a gap that suggests interventions may need to address multiple pathways simultaneously."
Types of Synthesis Relationships
Agreement: sources support the same point, providing cumulative evidence.
"Both Smith and Jones demonstrate that..."
Disagreement/Tension: sources conflict, requiring you to adjudicate.
"While Smith argues that X, Jones's data complicates this view by showing Y."
Complementary: sources address different aspects of the same topic.
"Smith establishes the scale of the problem; Jones's research identifies the most affected populations; Williams proposes a policy response."
Organizing a Synthesis Essay
Theme-based (recommended): organize by the ideas you're developing, not by source.
❌ Paragraph on Source A → Paragraph on Source B → Paragraph on Source C
✓ Paragraph on [Claim 1]: citing Sources A and B → Paragraph on [Claim 2]: citing Sources B and C
