These are corrected. Several stages are used. Much of the data is stored online as students use the programs. Distance learning' has a variety of usage, not all consistent with this vision. In the United States, distance learning often means about 25 or 30 students at a location different than the teacher or professor, too few for our visions.
Information transfer is the paradigm.
One view of distance learning is to produce a video of a lecture, at several levels of video expertise. Stanford University did this, starting with engineering courses to companies in the area. It was the approach of the Chinese TV University, perhaps the largest university in the world. The learning paradigm is information transfer. Even when email, chat rooms, and web sites are added, the learning paradigm is not fundamentally different.
