Learning objective
Produce a source-attributed synthesis, assess each source’s usefulness and identify a research gap.
Before you begin
- Take accurate source notes; distinguish counts from interpretations.
Gather your materials
- Paper or a note-taking document
- Pencil; the original lesson texts and records below
Language to know
- Credibility
- Reasons a source is trustworthy for a particular question.
- Synthesis
- A reasoned connection among sources with their differences preserved.
- Attribution
- Identifying the source of a statement or idea.
Understand the concept
Fictional archive for a school repair club: Record A, sign-in log, lists 30 visits across three meetings but does not track unique visitors. Record B, organizer note, says six repair requests were completed and four needed parts. Record C, one visitor’s account, says “I learned to identify a loose connection, but I still needed help choosing a part.” The question is whether the club should add a parts-identification session. The log addresses attendance volume, the organizer addresses requests, and the visitor offers one learning experience. Combining them does not turn thirty visits into thirty independently verified outcomes.
Teach it step by step
- Make source cards with creator role, recorded measure, useful question and limitation.
- Identify which two records most directly address parts identification.
- Write a synthesis with attribution and paraphrase rather than pasting the records into a list.
- Add a focused research question and explain what additional source could answer it.
Make the thinking visible
Worked example or model response
“The organizer’s record of four requests awaiting parts and the visitor’s need for help suggest a parts session is worth investigating. The attendance log shows activity but not how many learners share that need. A short anonymous needs check could test whether the issue extends beyond one account.”
Guided practice
Compare the phrases “Thirty students failed to repair an item” and “The log recorded thirty visits.” Explain why only one preserves the source’s measure.
Independent practice
Write a 150-word memo using all three records with clear attribution. Evaluate each record’s usefulness, paraphrase accurately and propose one focused follow-up question.
Quick assessment
Why is a credible attendance log not automatically credible evidence of learning?
Answer key & assessment criteria
Answers and teaching guidance
- Guided: The second phrase matches visits; the first changes the unit to unique students and invents failure outcomes.
- Independent criteria: Memo connects the records, preserves their measures, attributes ideas, identifies limits and proposes evidence matched to the research question.
- Quick check: Credibility is question-specific. A well-kept log can accurately measure visits while containing no learning assessment.
Look for: Memo connects the records, preserves their measures, attributes ideas, identifies limits and proposes evidence matched to the research question. Accept a different conclusion when it addresses the task and is supported by the supplied material.
Make it work for your learner
More support
Provide source-card headings and allow a two-source synthesis before adding the third.
Extension challenge
Identify a plausible contradictory source and explain how your recommendation would need qualification rather than selective omission.
