>>I just do not under stand what gender has to do with learning or following directives.
I never did, either. Seems like it comes up when someone wants to justify something. But we are all socialized, to varying degrees, as to what constitutes "proper" roles (and careers) by gender. And that socialization, plus a little biology, is the basis for generalizations.
So here are some general trends: women are better at communicating, are more detail oriented, and tend to be more receptive to praise and criticism. But I know several exceptions to every single one of these. The single best person I know for talking to little old ladies is a man - and he's a real jerk. But he has a gift for it. The only true sociopath I know is a woman.
Gender is simply the easiest and most obvious handle we can grab. But the good Lord made us all a little different, in His wisdom. I just try to follow Him.
