1) Brian Rybarczyk gives a presentation on active learning techniques to incorporate more student engagement and participation into classroom teaching. 2) Active learning involves students solving problems, answering questions, and participating in activities during class rather than just lecturing. It has been shown to significantly increase information retention compared to traditional lecturing. 3) Examples of active learning techniques discussed include think-pair-share, role playing, group quizzing, case studies, and assigning primary literature for student groups to analyze. The goals are to make the classroom experience more exciting and promote higher-level thinking.
