I'm going to try to answer the question, as I understood it to be asked. I think that's the advantage at the high school level of having teachers involved in coaching the kids. When you have the educational component, much of what happens in the classroom can be translated and applied to the court or the field or whatever.
Just to throw something in there, coaching makes better teachers, and teaching makes better coaches, in my mind.
On what they deal with in the classroom with both sexes, the idea is those skills you learn in the classroom from dealing with both sexes are transferable to the athletic pitch in some way.
Do we teach that this is how we coach girls and that is how you coach boys? No, we do not, and I'm not sure anybody does necessarily. You learn from experience. I've coached girls' basketball and I've coached football. I've looked at both. Sometimes you handle them differently, and sometimes you don't.
