“…That is one of the arguments for an all-women’s college like where my D attends - because all your math / science classes ARE all women…”
Well, there are pros/cons to that route. Regardless of how well you are able to participate in class and learn the material in college… you are still likely to work in an environment of mostly men. No right or wrong answer, but I psersonally have zero regrets about attending a STEM school (about 25% women in 1980s). I arrived at the workplace with plenty of experience working projects with mostly guys, and team dynamics is a big part of my work and many other engineering jobs.
As for why so few women in engineering, I’m thinking it is because women with high math stats often have high overall stats and qualify for other options too.
