I'm going to ask a practical advice here. As a male teacher, what can I do in a classroom to encourage more female students for math/logic/programming? I sometimes talk about how there are great female software developers out there and how gender shouldn't be hindering their talent, but that's about it. And when a female student isn't performing well and being bummed, I can't do much other than general vague-sounding encouragement. At the same time, I don't want to sound too pushy. I live in a very sexist country compared to the US (Japan) and there's not much advice on this kind of things from other educators. Is there anything else that I can do to help the cause?
