This document discusses active learning techniques that can be used in the classroom. It introduces think-pair-share, which involves students thinking individually, discussing in pairs, and sharing with the class. Variations include writing responses individually before pairing up. Think-pair-share benefits include engaging students and incorporating multiple perspectives. Other techniques discussed are numbered heads, three-step interviews where students take turns interviewing and reporting, and three-minute reviews where students summarize material in pairs. Active learning requires activities that motivate students to think and work in groups rather than just listening passively.
