Being very gifted in mathematical ways myself, it interests me that so many girls seem to have this idea that women "just can't" do it. That's clearly nonsense and I don't know where it comes from. Parents are clearly part of it yet I've known women engineer types who just can't convince their daughters to work hard at math. The other options are clearly, from other girls, from the culture, or from teachers. Or a combination of all of those.
I do know that there are some - maybe not many, definitely not all - teachers who know that they are not as smart as some of their studetns and resent it. Teachers who do not care to help a gifted student achieve. I would think that's an area where homeschooling can really help. Parents are supposed to want their kids to outshine them, after all.
