>The problem is that it's near impossible for a student to pay attention during longer classes.

Impossible seems a bit harsh. The situation could certainly be improved, and it might certainly be improved if the instructor has more time to engage in students as individuals, which can't be done much in a short period system (this was my main complaint with HS and why I never took a huge lecture course). I do agree that the current method of engagement, overall, is not ideal.

The problem is not the engagement as much as trying to sit and pay attention for 90 minutes. You will way better results by having a 5-15 minute break every 45 minutes.
