And this is how we reached the point where sleep is more common in a classroom than anything else.

I think this has more to do with sleep deprivation. I can probably count the number of days I got a full night's rest while in high school and college on one hand. Rather than making classes more interesting (though they could do this as well I guess), they should focus on not completely overwhelming the students with homework, although I'll admit that was more of a college thing.
