What problem does it solve?

This Skill helps students move beyond treating each historical document as a standalone answer by teaching them to compare accounts across sources to identify agreements, contradictions, and gaps—then use those relationships to reason about what is probable.

Core Features & Use Cases

• Corroboration progression: Provides novice, developing, and proficient indicators so teachers can see how comparison reasoning grows over time.
• Explicit multi-document instruction sequence: Includes a teacher think-aloud, guided practice that makes comparison deliberate, and independent practice with monitoring criteria.
• Comparison prompts + failure patterns: Supplies prompt templates and common misconceptions (like “isolated reading” or “picking a winner”) to diagnose and redirect student thinking.
• Assessment indicators: Defines observable signs in discussion and writing that corroboration is happening.

Quick Start

Use the skill to generate a corroboration lesson plan by providing the historical topic, the student level, and the current challenge students show with multi-document analysis.
