As a former young player, this stereotype bothers me. There is enough similarity with the methods these days, and this is could be an illegal question in the HS setting, thinking of Title IX and gender bias. This is NOT a question that should be asked.
When you look in any coaching manual, such as ASA, you see no gender difference/-based coaching method. I would say that these books recommend the type that used to be only 'for girls,' ie, the positive rather than negative/yelling method.
Boys and girls both respond to that method. As I have said before, this question or approach implies that girls require "complicated methods" while boys do not.
You could ask, perhaps, what is the difference between coaching fastpitch softball and baseball.
