Define cross-cultural corroboration. Walk through an example: on the question of how the Inca built terraces, INSIDER VOICES include Garcilaso de la Vega (Inca-Spanish chronicler 1609 - half-Inca own-voice), Quechua oral tradition, and contemporary Quechua scholars at CTTC. OUTSIDER VOICES include 16th-century Spanish conquistador accounts. The voices may agree on WHAT and differ on WHY/WHO. CRITICAL FRAMING: insider voices are NOT automatically right and outsider voices are NOT automatically wrong - but the OWN-VOICE CHECK is the default discipline.

Key examples
  • Notice: 'corroboration' is not about ranking voices into right and wrong - it is about identifying where each voice has authority.
    model The Spanish account is interesting as an OUTSIDER VOICE from the 16th century - it tells us what a European visitor noticed. The contemporary Quechua scholarship is the INSIDER VOICE with deeper continuity to the building tradition. The historian uses both BUT defaults to insider expertise on questions of cultural meaning and technique.
    prompt On the question 'who built Inca terraces and how,' how would the historian weigh a Spanish chronicler's account vs. contemporary Quechua scholarship?
Checks for understanding
  • What is corroboration? What is the OWN-VOICE CHECK?
Sourcework

Children examine sample source pair sets: an own-voice source and an outsider account about the same event/person/practice. They apply the 3-column Cross-Cultural Corroboration Chart and the OWN-VOICE CHECK from MG-7 Box 6.

Set of 4 laminated source-pair cards, one per studied culture. Each card has TWO sources: one OWN-VOICE INSIDER (green border - Quechua scholar quote on Inca terraces; jeli's Sundiata line; Tang poem; Polynesian voyaging chant) and one OUTSIDER (orange border - Spanish chronicler account; European traveler observation; outside historian claim). Source attribution and dating visible on each card.

Teacher notes

Lesson 16 is the unit's central historiographic-discipline lesson. The OWN-VOICE CHECK distinguishes this unit's source-analysis from generic 'evaluate the source' lessons. Trauma-informed note: 16th-century Spanish chronicler sources contain language that is ethnocentric - teacher vets and edits sample sources at G3-light.
