I don’t see how classrooms are practical places for learning unless it’s all guided study where each student is doing their own thing and the teacher is there to help them stay on track and answer questions. Lectures are so completely outdated, even if they are interactive. If I find a tutorial series on YouTube I can watch it at 2x speed, screenshot or make a video recording of any part I want to review and skip anything that is redundant to me.

A tutorial and a recorded lecture are basically the same. The benefit of live is being able to ask questions/have a discussion. Theoretically, it shouldn't matter whether it is live in a classroom or online but data shows otherwise.

During COVID, when classrooms turned into Zoom meetings, students did worse on average. Could be other factors involved of course and different people learn better in different ways.
