Peer influence and negative stereotypes
Yes, children/young adults have to get over peer pressure and negative stereotypes. This is not a gender specific problem. The nerd/geek stereotype is not a positive one, yet men and women overcome this "problem" all the time and pursue their interests. Segregation would solve this, how?
positive female role models
You can do this in a co-ed classroom.
an environment where it's acceptable for them to indulge in those interests
Girls can't learn in the same classroom as boys, is what you imply. Why stop at CS then? Why not gender segregated schools? Segregated workplaces? If girls can't learn with boys can they work with them? Segregation worked so well for race it should work for gender too.
This woudn't be the case in a co-ed classroom
I disagree. You can speculate all you want about gender segregation but in the real world men and women have to work with each other.
Just facing a male-dominated classroom, where they're very likely to be subjected to unwanted comments and advances, can be intimidating. It's certainly not conducive to learning.
If it is behavior that is disruptive to learning, the teacher is the arbitrator and can adjust the offenders behavior by kicking them out (for example). Unwanted comments and advances??? We are talking about K-12 right? I didn't realize kids so young were so forward... high school maybe but then, do you get that in English class? How do we stop it there? Why is CS so different?
That you can't find a single legitimate reason for 'girls only' programs tells me that you don't understand the issues at all.
To use your logic: Because you can't find a single legitimate reason for co-ed tells me that you don't understand the issues at all. You didn't address my reason for against segregation therefore you don't understand. Brilliant...
Really, it's quite simple: women and girls face significant obstacles that men and boys don't. If that's not inequality, I don't know what is! By reducing those barriers, we help to give them equal opportunity.
If it was simple, it wouldn't be an issue. yes, men and women face obstacles. Life is full of them. An ability to overcome those obstacles is a good thing, IMHO.
What you want is equal outcomes, not opportunities. Boys that have "informal opportunities", spend their own time to cultivate an interest. Yet, Girls are not. because they have different interests. FTFA, they are not as interested in working with computers, computer animation, computer programming and computer games . They prefercommunal careers.
And have chosennot to work with computers in high school.
Again, i think that growing children's interest in CS is a good thing... But I don't like it when a boy now has less formal choices because of some informal advantage that girls could have if they spent their time with it.... That is not equality. You make women sound weak.
