Hi Charles, Great advice here. Anything that helps.
Here in Australia we certainly deal with the different types of intelligences through the work of Dr Howard Gardner. I'm pretty sure he's American.
I also have a view on why kids are out of control, and that is, their diets, where they are eating non-food, foods. Some children are having huge intolerances on food additives. I was actually involved in a very frightening situation after a student ate food that he knew he was allergic to. a kid.
