IB DP TOK – Exhibition & Essay Skills Evaluating Sources of Knowledge

IB DP TOK – Exhibition & Essay SkillsEvaluating Sources of Knowledge | Build a Reliability Toolkit

Help students move beyond “Does this source look trustworthy?” and develop a practical process for determining why, when, and for what purpose a source deserves their trust.

This no-prep TOK lesson introduces students to lateral reading, source verification, and calibrated trust. Students investigate how professional fact-checkers evaluate information, identify the core questions that should be asked of any source, and examine why different source types require different evaluation methods.

Students then work collaboratively to Build a Reliability Toolkit they can actually use. The lesson culminates in an important TOK challenge: applying the same evaluation standards to sources students already know, use, and trust.
