A flipped classroom is basically exactly what it sounds like as it "flips" the usual classroom model. Instead of using class time to lecture, students are instead assigned videos to watch, often as homework. Class time is instead used for working out problems based on the material while a teacher is there to help and ask questions.
Pros: Students are again allowed to move at their own pace. The scheduled class times would allow students to ask questions of the teacher in a more organized fashion than in an asynchronous class. There are also already a great deal of resources for this model that we could use (e.g.,
http://www.flippedmath.com/). Many teachers have had success with this style in the past, and using their experience would make the transition easier.
Cons: This classroom style interests me, and I was hoping to make it my recommendation, but I believe the cons simply make it incompatible with our course. The largest con is the difficulty of helping the students in our online setting. In a typical flipped classroom, the teacher is able to walk around and help individuals while everyone else continues at their own pace. However, the online setting of this class makes this idea very impractical. It is difficult enough in the online chat room to help the students when they are all on the same lesson, much less when they are all on different chapters. This would make the scheduled time very frustrating for most people as they hear material they have either mastered or have yet to learn, and attendance would almost certainly be low. While this model holds a lot of promise, it's simply not practical for our online offerings.
