This article on Purdue podcasting class lectures has me split. On the one hand, it's a great convenience in case you need to miss a class. On the other hand, it's one step closer to virtualizing the whole classroom experience. If you have the podcast, plus the class lecture powerpoint, plus online practice questions, plus IM/video chat with your TA...then, well, why are you physically on campus?
Maybe that's the point...it is, after all, cheaper for the institution. I still feel it's a suboptimal way to learn. Maybe I'm just an old hat, though. Still, I wouldn't feel like I was getting my money's worth unless I could actually interact (physically or virtually) with a professor, ask questions, get feedback, and so on.
