Found via Online Learning Update - Decline in attendance puzzles professors - Matt Krupnick, the Telescope. Interesting piece that addresses something I've wondered about for a while. If it's a class with 700 studens and pure lecutre, and you have a taped lectured and notes on the web, why bother going to the live class? Especially if you can play back the lecture in a fast-forward mode (one of the coolest features out there). Of course, what you also soon realize is that going through a long taped lecture isn't all that great - what you really want is the transcription.
And, if you have the taped lecture and the notes, why bother doing a new lecture again the next year?
It does raise some very interesting questions!
