This is pretty easy to disprove.

Back in the new math era female enrolment in C Sc at UVic was about 1 in 3.

That changed to 1 in 10, with an overall drop in enrolment in math intensive courses, computing, engineering, chemistry, math, physics, ... from one September to the next, when the first victims of an experimental math curriculum arrived on campus. That teaching disaster happened pretty much all across Canada and USA at the same time as the fad math curriculum failed the post school reality check.

That shows that teaching methods have more effect than gender on getting into the types of post secondary education that matters at computer services companies such as Google.

An irony of the experimental curriculum was that it tried to appeal to traditional female gender stereotypes by including problems with adjusting cooking recopies and so on. It had the opposite effect, rather than having more appeal to female students.
