I believe that if students of one gender aren't learning well in a coed environment, it's the fault of the teachers, not of the coed system. If boys and girls do learn in different ways, teachers should be able to accommodate both ways. Good teachers do this all the time now, based on the personalities of the individual students.

Back in the 70s they decided that there was no biological difference between boys and girls, so they worked to make everything gender-neutral, which resulted in boys being drugged with Ritalin to make them more girly, and making girls grow up to abandon their children in search of a career.
I don't think that was "gender-neutral." I think that was just replacing one set of expectations with another. I don't think we can ever prove whether gender differences in behavior are the product of nature or nurture or some combination.
In any case, I believe that society having gender-based expectations amounts to the social engineering that you're talking about. I agree that it was wrong to "make girls grow up to abandon their children in search of a career." It was also wrong to teach girls that they had to bear children in order to be a complete woman, which was done for decades. In both cases, kids were told they had to live their lives according to someone else's agenda.
