I think her idea was to teach maths without assuming skill in spatial rotation, which a lot of girls really do struggle with (although it CAN be developed by teaching technical drawing, where it's the primary skill involved. I know, I suffered through it, but it did help). So basically she's not saying anything new -- just that if your student doesn't understand the methodology you're using, you need to change that methodology rather than just accept that the student is going to do poorly. I don't think she imagines separate classes for girls; obviously that'd be a joke. But a few modifications to the way maths is taught, why not.
