Simon Lancaster discusses flipping roles in education through lecture flipping. He describes their model of lecture flipping where students watch a recorded lecture before class and class time is spent engaging students through interactive activities and questions. He discusses using techniques like peer instruction and student-sourced questions. The importance of questions is emphasized to confront misconceptions and facilitate thought. Peerwise, a platform for students to create and answer each other's questions, is presented as a way to structure questions for flipped sessions. The conclusion suggests starting with small changes, fully committing to flipping, and relinquishing control to students.
