If instructors desire students to gain a deeper understanding of the content and begin thinking like experts, then they need class time for active, collaborative learning. In the flipped classroom, primary knowledge acquisition occurs before class, which creates space for students to practice applying the information of the discipline with their peers. Team-based learning is an effective in-class, instructional-strategy that (1) assesses and enhances student content acquisition from pre-class study, and (2) uses the majority of class time for activities that enable them to discuss, take-risks, and make mistakes while developing their expertise.
