In debate, you conduct research in depth on a particular topic. You prepare to debate on the affirmative side supporting the topic, and on the negative side refuting the topic. You debate both sides in the course of a tournament. Debate teaches you research methods, analysis, organization, vocabulary, critical thinking and logic. This means that you will generally appeal to logic and reasoning rather than just evidence.
Team debate is two-person team debate on a policy topic.
As affirmative, you prepare a plan to solve some problem related to the topic. Team debate demands many times more work than Lincoln-Douglas, but it is that much more rewarding. See Mr. B in room 472.
