Overview
Two teams take opposing sides of an issue and present arguments with evidence. Teams prepare their case, present opening statements, cross-examine each other, and give closing statements.
Educational Purpose
It teaches students to build evidence-based arguments, anticipate counterarguments, and communicate persuasively. These are critical thinking and communication skills essential for college and life.
Educational Psychology Behind It
Argumentation theory (Toulmin, 1958). Constructivism -- students build understanding by defending a position. Also draws on critical thinking research.

Argumentation theory (Toulmin, 1958). Constructivism -- students build understanding by defending a position. Also draws on critical thinking research.
When to Use It
Any topic with two clear sides: historical decisions, ethical dilemmas, science controversies, literary interpretations.
When NOT to Use It
Do not use without teaching argumentation skills first. Do not let it become personal -- focus on ideas, not individuals. Ensure both sides are equally strong.
