Yes, I agree that this is a big part of the problem. I think that even passively engaged in a lecture during class imparts some information (perhaps by osmosis) and it's the forcing aspect of the traditional classroom lecture that is better than a video.

Overall I think the problem comes from a lack of a desire to learn. I'm not a motivator and so I think my students suffer from my inability to be a rah, rah type instructor. I don't know what can be done about it though.
