So much this: cs61a at Berkeley for example has almost 2000 students in a single class, the idea of personalized anything with that many students is total unfeasible.
Berkeley is a public university, so many students qualify for federal aid and wind up paying very little or nothing at all,the full cost of in state tuition to those who can afford it is about $6000 per semester.
This is ridiculous. Why do Americans pay thousands of dollars for a bit fancier version of MOOC? When I studied we had 200 people on a course sitting on lectures, 30 on practical sessions and everyone could have a personal session during the professor’s office hours.
There is some kind of a massive waste of money going on.
