Unlike the majority of people here, I actually have experience being female. We moved around a lot when I was a kid so I attended several different school systems in 6 states in the 70's and 80's. I was a nerdy kid, very interested in science. I have never been a math genious but always did quite well in the subject, and enjoyed it, when I had a good teacher. I can't remember one time where any teacher, male or female, discouraged me from science or math. In fact, I remember quite the opposite. My mother, though, she was another story. When I was in 3rd/4th grade I decided that I wanted to be an astronomer. Apparently she had taken astronomy class at a community college, and it turned out to be all math. She failed the class and her takeaway from that was that she is bad at math, and therefore all girls are bad at math, so that meant I couldn't be an astronomer, because it's all math. And of course I believed her. Why wouldn't I? Nevermind that I placed very highly on all standardized tests, including math. In junior high they took me out of regular classes, put me in the gifted & talented program, and I took all the advanced math classes all though high school. I took a CS class in high school, had a Commodore 64 and wrote programs in BASIC. I tested out of my math requirement for my bachelors degree and then after grad school took a couple of calculus and astronomy classes just for fun. All that time believing that I was bad at math. It's very hard to overcome that type of bias, no matter who puts it in your head, even in the face of evidence telling you otherwise. Kids really absorb that stuff. I think it wasn't until I was in my 30's that I realized I was never actually bad at math. I'm now a computer programmer. Can you imagine if my mother had been a teacher? Thank goodness I was the only girl she had influence over.
