My wife, a student in Catholic Schools in the sixies, says that the Nuns had a sure-fire "cure" for ADHD. It was called a "ruler." You caught their attention, your got the "cure." Unsurprisingly there was rapt attention to what was going on in school and young people did their work as directed.

Of course we can't do it that way anymore; it wouldn't be progressive.

It was called a "ruler."

Try hitting a child with a ruler today and see how fast one ends up in a local jail cell and losing every possession owned.

Usually, kids got “the ruler” at home, too. So teachers hardly had any behavior to even complain about.
