Of course it does. But usually there is no interaction because most people do not interact.
Usually as a student I did raise my hand and asked questions and was the only one or sometimes we were two or three at most in a class of 40 people. Then in a class of 100, or 200 in the University.
Most people sit still, passive. They do not interact. Those people are better served with a video they can play at 2x and rewind multiple times, do automatic speech recognition,use with anki, archive and search.
In fact the best way to learn is a one on one interaction, that would be too expensive to have. I was getting it because most people did not use their share.
