I'm undergrad right now and had a class that you describe. It was a web development course, so our teacher posted prerecorded lectures two days before class and we would watch them and do homework exercises on the side that were then due by the end of that next class (so you could ask questions). I actually had so much fun doing this. This worked for me is because I could take the lecture at my own pace; pause, fast forward, etc. Essentially, I could be efficient and effective. I think those that say "he didn't even teach us anything, he just made us watch videos" are a bit out of touch with how learning works these days. You can find almost any resource online and read up on it yourself. That's how I've learned a lot of what I've done. Having a supplemental class period to expand on this idea is very important, and I think it's a shame some of my peers don't realize this. They expect you, the professor, to engrave it in their heads, but there is a shared responsibility here. Sitting in a lecture doesn't mean you're going to automatically understand the material; you actually have to think about what is being said. That's also why I liked my recorded lectures; I felt even more responsible for making sure I understood it before coming to class.
