Conversation: Flipping Out: Flipped Teaching Models

I mentioned in my review of Blackboard that it could be an excellent tool for developing a flipped classroom model, but I wanted to explore that idea a little further. Here's an infographic from Knewton that explains the concept and why it's getting so much attention in discussions about education.

Basically, in a flipped model, we record our lectures for students to watch at home at their own pace (and technology advancements in PowerPoint and Prezi make that pretty easy to do). This frees up the classroom time for more actively engaged learning and group work. 

What do you think of a flipped classroom model? What concerns do you have? Are there any concerns particular to developmental students, or could a flipped model be even more helpful for these students?
