Until someone figures out how to create true electronic communities, it isn't going to expand very rapidly because people like to learn in communities, and until you can create them they are going to be in classrooms. I haven't the vaguest idea. That's somebody else's job to create. That's not mine. But everyone will know it when it happens.
People talk about it.
I suppose you have chat rooms and things like that, but so far they haven't created very effective virtual learning communities. I don't know. I think maybe it's a generational thing. Institutions of higher education are going to have to be managed more and more as a business to stay in existence. They're going to have to install good financial and management software, to develop management structures that are based on industry.
