> Last year, his school offered a robotics class for girls only. When my son asked why he couldn't join, it was explained to him that girls need special help to become interested in technology, and that if there are boys around, the girls will be too scared to try. And that's why we can't use sexism to fight sexism (or mistakenly enforce the same composition of the general population on self-selected subsets).
I disagree. As a high schooler, I know many intelligent and creative young women who don't want to do robotics or programming because of the people in those fields. High school boys in tech are much more likely to be misogynistic and socially inept than other high schoolers are. They make girls uncomfortable (they make me uncomfortable too, and I'm not event the subject of their creepiness), and this discourages girl…
I think that you give highschoolers too little credit.
Rocketry and science competitions are not really any different from robotics and programming. None of them are exactly football team, if you know what I mean. The only real differences between "model rockets nerdy" and "programming nerdy" are a result of how the adults treat the participants.
