1. Recently I was reading how in the early public school system, students of a widely different age all sat in the same class.

The bigger kids will learn first from the teacher, and in turn, turn around and teach the younger ones.

At least according to this article, it works. Maybe high school can also benefit from this.

> Third, it’s fun for them. They can laugh and joke with each other, rather than sit in silence as I repeat information that’s right in front of them anyway.

Usually the teacher is doing his best to get the class as quiet as possible.
