I’m an undergrad right now preparing to take an exam for a course that was taught this way (Single Variable Calculus, https://youtube.com/channel/UCLzpR8AiHx9h_-yt2fAxd_A https://youtube.com/channel/UCLzpR8AiHx9h_-yt2fAxd_A). Overall I felt like the course was better for being taught this way, and my classmates mostly think similarly. I think one key differences from what you’re describing though is that instead of periods to work on homework lectures were directed periods of applied learning where the professor gave us problems one by one and walked us through them when we got lost. Overall I felt like this made the lectures more essential not less. In my other math lectures the professors mostly just explained the material in the textbook/notes that you could learn just as easily on your own. The applied learning style of the lectures for this course made each lecture unskippable if you really wanted to understand the material. The problems in the textbook didn’t come with any explanation for their solutions, and weren’t as similar to the problems on the tests and the problem sets as the problems in the lectures, so there was a lot of value lost if you missed a lecture. For me personally, I prefer learning directly from the textbook so the videos were not that great, but the interactive lecture style is how I would want all of my future math courses to be taught, if I could choose.
