Evidence Synthesis & Psychology Research Brief Workshop

Retrieval Warm-Up

Without notes, write one idea you already know that might connect to Evidence Synthesis & Psychology Research Brief Workshop. Then write one question the lesson should help you answer.

Essential Question

How do researchers combine sources without flattening disagreement or exaggerating certainty?

Learning Objectives

Students will be able to:

• distinguish evidence synthesis from source listing;
• evaluate source relevance, quality, independence, and method;
• identify converging and conflicting evidence;
• separate direct evidence from interpretation;
• construct a claim-evidence-limitations paragraph;
• prepare a polished research brief with honest visuals and citations.

primary source

Vocabulary in Context

primary source · secondary source · empirical study · review · converging evidence · conflicting evidence · triangulation · citation · evidence hierarchy · uncertainty · synthesis

Substantial Core Reading

Research synthesis is not “three sources agree, therefore true.” Sources can repeat one another, use the same sample, measure different outcomes, or differ greatly in quality. Students learn to ask whether evidence is independent, relevant, methodologically strong, and actually about the same claim.

A strong research paragraph follows a disciplined structure: Claim → Evidence → Interpretation → Alternative/Qualification → Limitation → Proportional Conclusion.

Students also learn that disagreement is information. Good synthesis explains why findings may differ rather than hiding inconvenient results.

Worked Example / Synthesis

Three sources discuss study habits:

• one randomized experiment on retrieval practice;
• one correlational survey on student preferences;
• one popular article summarizing both.

Students explain why these are not three independent pieces of equally strong evidence.

Psychological Scientist's Desk

Claim: “Five websites say the same thing, so the claim is well established.”

Students audit source independence, original evidence, citation chains, methods, and relevance.

Data Lens

Students choose between two possible graphs for the Research Brief and identify which visual communicates the data honestly. They inspect truncated axes, missing labels, inappropriate 3D effects, and percentage claims without denominators.

Claims Laboratory

Evaluate:

• “More citations make a stronger argument.”
• “A review article counts as all of the studies it cites.”
• “Conflicting studies mean psychology knows nothing.”
• “A graph is objective because it uses real numbers.”
• “You should leave out evidence that weakens your conclusion.”

Guided Investigation

Build a Claim → Measure → Evidence → Alternative Explanation → Limitation → Conclusion map for Evidence Synthesis & Psychology Research Brief Workshop.

Extended Inquiry from the Locked Plan

Independent Assignment

Draft the complete Psychology Research Brief using the final project structure. Include at least one explicit alternative explanation and one generalizability limit.

Research Notebook Checkpoint

Complete the Evidence Convergence Map:

• strongest evidence;
• weakest evidence still retained;
• conflicting evidence;
• source dependency/overlap;
• evidence that changed the working conclusion;
• evidence still missing.

Academic Journal Reflection

What does a researcher gain by including evidence that complicates the preferred explanation?
