Robert Talbert, a math professor at Grand Valley State University, talks about his new book on flipped learning—a method catching on these days in college classrooms. He describes it as a new philosophy of teaching. Unlike the lecture model, in which students first encountering new material in the classroom, in the flipped model the students’ first encounter with the material happens outside of class, usually in the form of video lectures. And class time is used for more interactive activities that encourage students to apply what they’re learning while the professor is there to step in and help if necessary. EdSurge sat down with Talbert to talk about his experiences, and why he thinks more research universities are taking teaching more seriously these days.
