Below is Karl's time-lapse video, which is followed by the one I created a few weeks ago. You will notice some commonalities between the two, students are active and engaged! We did not record "our best lecture," but instead captured students engaged in various learning tasks. You will also notice that Karl is able to spend a considerable amount of the class time talking with students and helping them individually as they work through their assignments. This is one of, if not the most, important advantage of flipped learning practices.
