Very interesting point about the context switching. When I was a student I didn't consider such matters, but as an adult I recognise needless context switching as an enormous inefficiency. You're point about only needing a teacher when you get stuck is quite valid as well, especially in the age of high tech. Presentation of the information should be optimized and presented via recording. The duty of the teacher should be to facilitate learning by helping out where there are any problems. But with all the politics and tradition, the status-quo isn't about to change unfortunately. The upside is that there is room for huge improvement, hence opportunities exist.
