Maybe they have to prove they can be "selectively aggressive". Our girls hit below 200 if one of the two first balls is in play. That was a 7 game span .. not hundreds like you can find in a baseball encyclopedia. They are better off fouling off and at least getting to a third pitch. My opinion on my DD's team was they wanted to be "selectively aggressive" but did not have the skill yet to do it. How to teach that thought is the real skill.What are your hitters doing in the warm up circle/on deck? Chatting with their BF's? Shouldn't they be looking at the pitcher warming up? Shouldn't you the coach/dad be looking at the pitcher as she warms up. I tell my DD first 2 strikes are hers. The last strike your hitting the umpires strike. I don't care what the count is first pitch that you see that you like swing. Of course sometimes game situations dictates when you can swing or take a pitch.
A little socratic teaching.
The Socratic method (also known as method of elenchus, elenctic method, or Socratic debate), named after the classical Greek philosopher Socrates, is a form of inquiry and discussion between individuals, based on asking and answering questions to stimulate critical thinking and to illuminate ideas. It is a dialectical method, often involving a discussion in which the defense of one point of view is questioned; one participant may lead another to contradict himself in some way, thus strengthening the inquirer's own point.
The phrase Socratic questioning is used to describe a kind of questioning in which an original question is responded to as though it were an answer. This in turn forces the first questioner to reformulate a new question in light of the progress of the discourse
