Corroboration and Paraphrase Practice — When Two Sources Agree (or Disagree)
- Students identify when ≥2 sources corroborate the same fact (CHECK-IT validated).
- Students paraphrase the same source-passage 3 times in increasing fidelity and pick the best.
Lesson plan
Warm-up
5 minTeacher shows two sources for one fact about Sojourner Truth's 1851 speech. Children compare: do they say the same? Different? Why might they differ?
- Project both passages
- Identify the matching fact
- Note differences in wording vs. differences in claim
Direct instruction
13 minToday you do two things: practice CORROBORATION (the 'CHECK-IT' move from lesson 2) by comparing two sources, and practice PARAPHRASE FIDELITY by re-paraphrasing one passage three ways. Corroboration: when two sources tell us the same fact, the fact is more credible. When two sources DIFFER on a fact, the researcher notes the difference — sometimes one source is wrong, sometimes both have part of the truth. Watch teacher compare two sources on Sojourner Truth's 1851 Akron speech. SOURCE A (Painter biography): 'Truth spoke in Akron in 1851, and her exact words were not transcribed at the time.' SOURCE B (online history site): 'Truth's famous speech included "Ain't I a woman?" in Akron in 1851.' BOTH sources agree she spoke in Akron in 1851 — CORROBORATED. The phrase 'Ain't I a Woman?' itself was added in a published version 12 years later — sources differ on whether she said the exact phrase. Note the corroboration AND the difference. Paraphrase fidelity: read a source passage. Write the paraphrase 3 ways — TIGHT (very close to source words), MEDIUM (some words changed), LOOSE (mostly your own words). Pick the BEST — usually MEDIUM. TIGHT risks plagiarism; LOOSE risks distortion. MEDIUM keeps the source's meaning in YOUR voice.
-
Notice TIGHT keeps the source's word order. LOOSE loses precision. MEDIUM is the researcher's target.model ORIGINAL: 'Sojourner Truth was born in upstate New York and spoke Dutch as her first language because her enslavers were Dutch.' TIGHT: 'Sojourner Truth was born in upstate New York and spoke Dutch first because her enslavers were Dutch.' (too close) MEDIUM: 'Sojourner Truth was born in New York, and Dutch was her first language because the family that enslaved her spoke Dutch.' (good — meaning preserved, words changed) LOOSE: 'Sojourner started life in New York speaking another language entirely.' (too loose — loses key facts)prompt Teacher paraphrases one Sojourner passage 3 ways.
- When two sources corroborate, what does that mean for the fact's credibility?
- Why is MEDIUM paraphrase usually best?

Formative assessment
5 min- Show 1 corroborated fact (both sources named).
- Show 3 paraphrases of one passage with the best starred.
Closure
1 min- Star your most corroborated fact.
- Predict: tomorrow we meet TIES — the informational body paragraph routine.
Homework
10 min- Find one fact that appears in two of your home/library sources. Bring both citations on a sticky note.
Exercises in this lesson
Differentiation
- Pre-matched source pairs (teacher pre-selects fact + 2 sources)
- Paraphrase scaffold: provide TIGHT and LOOSE; child writes MEDIUM only
- Reduced target: 2 paraphrases instead of 3
- Find 3 sources for one fact and triangulate corroboration.
- Identify a fact where your sources DISAGREE — record both and propose resolution.
- Bilingual source-pair passages
- Cognate notes (corroborate/corroborar; paraphrase/parafrasear)
- Paraphrase rehearsal in home language first
- 1 corroboration + 2 paraphrases instead of 3
- Adult scribe
- Source-pair passages at higher visual contrast
Teacher notes
Corroboration is the entry-level form of Wineburg's corroborate heuristic. Children may treat any single source as sufficient — push for the 2-source check on at least 3 facts per report. Paraphrase fidelity is the most common error-zone: TIGHT slides into accidental plagiarism, LOOSE slides into distortion. The 3-version routine makes the middle visible. Watch for children who can't tell which version is best — they may need more mentor-text exposure to recognize the rhythm of academic paraphrase.
