The problem is most lessons are already broadcast only. When you have 30 students in class, it's very hard to take a individual approach. Yes I agree the individual approach is better. But have you considered that videos, when dealing with a class of 30 is actually more individual. A individual student can pause, rewind etc for his own needs. Where as in a class he could not do this. You can't rewind a teacher, if anything the teacher could get angry. If anything this allows more time for tutoring, rather than lecturing. Allowing the teacher more time for one on one work.
