Corroboration and Paraphrase Practice — When Two Sources Agree (or Disagree)

Objectives
  • 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.
Vocabulary

Lesson plan

Warm-up

5 min

Teacher shows two sources for one fact about Sojourner Truth's 1851 speech. Children compare: do they say the same? Different? Why might they differ?

Teacher moves
  • Project both passages
  • Identify the matching fact
  • Note differences in wording vs. differences in claim

Direct instruction

13 min

Today 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.

Key examples
  • 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.
Checks for understanding
  • When two sources corroborate, what does that mean for the fact's credibility?
  • Why is MEDIUM paraphrase usually best?

Tasks
  • Pick ONE fact from your research that you can find in TWO of your sources. Compare the two sources. Note: corroborated? Or do they differ? Record in your notes.

Formative assessment

5 min
Exit ticket
  • Show 1 corroborated fact (both sources named).
  • Show 3 paraphrases of one passage with the best starred.
scoring Corroboration + 3 paraphrases with best identified = mastery; one missing = practicing; both missing = reteach.

Closure

1 min
Moves
  • Star your most corroborated fact.
  • Predict: tomorrow we meet TIES — the informational body paragraph routine.

Homework

10 min
Tasks
  • Find one fact that appears in two of your home/library sources. Bring both citations on a sticky note.

Differentiation

Scaffolds
  • 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
Extensions
  • Find 3 sources for one fact and triangulate corroboration.
  • Identify a fact where your sources DISAGREE — record both and propose resolution.
English Learners
  • Bilingual source-pair passages
  • Cognate notes (corroborate/corroborar; paraphrase/parafrasear)
  • Paraphrase rehearsal in home language first
Ieps 504s
  • 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.
