Well-timed, appropriate humor can provide relief in tense classroom environments. Humor can be especially critical in active learning environments, where students’ immersion can heighten anxiety and stress. In this video, Mandell, his teaching assistants, and students discuss the central role that humor plays in whole group sessions following simulations. After the intensity of the learning activity and the constructive criticism of “hot” debriefs, humor becomes a helpful tool to keep students engaged and allow them to reflect on mistakes with some levity.
