IB DP TOK – Exhibition & Essay SkillsEvidence & Justification in TOK | Evidence Ranking Activity

Help students move beyond asking “Is this evidence reliable?” to the much more TOK-focused question: “Reliable evidence for what?”

This no-prep Theory of Knowledge lesson explores how standards of evidence and justification change depending on the discipline, context, and question being asked. Students compare approaches used in areas such as medicine, history, mathematics, and personal testimony before designing an interactive Evidence Ranking Activity that puts those ideas into practice.
