Indeed. If we had unlimited resources, the best way to teach would probably one teacher per one (or two-three) child(ren). When you're working closely with one student, you can focus on just what that student needs to learn/needs help with. That probably doesn't scale up to the wide level of schooling that a modern industrialized world needs though (Maybe we should leverage that wasted extra efficiency we've picked up to recruit everyone in the work force to work 4 days at their job, and 1 day as a teacher?).

It sounds like this kind of computer-assisted learning might be able to increase teaching/learning efficiency similarly to what can be achieved with good one-on-one tutoring.
