Learn the idea

A claim must match the record’s people, time and measure. Association alone does not establish cause; a universal claim can exceed a small sample; direct contradiction needs correction.

Compare the stated claim and record carefully. Name the demonstrated mismatch rather than adding speculative objections.

Original worked input: Original excerpt C: Six volunteers replied; four favored larger type. Claim: Four of these six favored larger type. The task is to test a claim against its evidence. The answer is “claim fits the evidence scope”. Evidence: Six volunteers replied; four favored larger type. Claim: Four of these six favored larger type. Reasoning: claim fits the evidence scope is supported because claim and observation describe the same limited sample and count. Do not infer cause from a simultaneous change alone.

1. Read the supplied worked case and identify the part named in this lesson. An adult can model unfamiliar words.
2. Compare the stated claim and record carefully. Name the demonstrated mismatch rather than adding speculative objections.
3. Check the worked solution: claim fits the evidence scope. Evidence: Six volunteers replied; four favored larger type. Claim: Four of these six favored larger type. Reasoning: claim fits the evidence scope is supported because claim and observation describe the same limited sample and count. Do not infer cause from a simultaneous change alone.
4. Use the new primary and practice cases. Give a reason from the actual words before checking the feedback.

Take it further

Changed-input task: Original excerpt C: The attendance log records six visitors. Claim: Twenty visitors attended. Give an evidence-based answer before looking at the model. Expected reasoning: Evidence: The attendance log records six visitors. Claim: Twenty visitors attended. Reasoning: claim contradicts the supplied record is supported because the claim directly conflicts with the supplied count. Do not infer cause from a simultaneous change alone. Then write a brief alternative sentence, paragraph, source note or scene that demonstrates the same operation; label new fictional details and preserve source limits.
