> Learning tools like this would have saved my teachers a lot of headaches if they were available 10 years ago. This type of teaching has a formal name. It's sometimes called course delivery reversal or course flipping, with the idea being that, essentially, the "lecture" is done outside of the class, and the "homework" is done within class. In this way, you can have a subject matter expert present at the time when he or she is actually needed. I've tried it in my own courses (recording in Camtasia and having students watch the lecture outside of class, where they can rewind, pause, etc.), then dedicating the entire class time to allow the students to actually work problems. More generally, active learning has been gaining popularity in the classroom.
