Benefits of Teaching a Large Course Using a Flipped Zoom Classroom

In Fall 2020, we conducted CSE 260 (Discrete Mathematics) as a flipped class, where students were expected to watch videos before class so that they could use class time to work together to solve problems. This class covers foundational mathematics for computer science and computer engineering students. Students need a lot of practice to master the methods and concepts. Unfortunately, these problems do not provide an instant feedback mechanism similar to programming projects. A flipped class where students work together in a group, along with regular assistance by the instructional team, provides such a mechanism. We surveyed students to gather their impressions on the course. Most students liked the flipped class structure and generally preferred it to a traditional lecture format. Furthermore, students reported it helped them develop friendships, something difficult to achieve in the Covid-era.
