Clay Shirky drills down into the question of what MOOCs are and what they are not:
The possibility MOOCs hold out isn’t replacement; anything that could replace the traditional college experience would have to work like one, and the institutions best at working like a college are already colleges. The possibility MOOCs hold out is that the educational parts of education can be unbundled. MOOCs expand the audience for education to people ill-served or completely shut out from the current system, in the same way phonographs expanded the audience for symphonies to people who couldn’t get to a concert hall, and PCs expanded the users of computing power to people who didn’t work in big companies.
If he is right, the big question is: For how many current and potential students will MOOCs be “good enough” to justify not attending a traditional college?
