Back in England in the 60s I felt strongly that high schools worked better for girls if they were girls only. None of the dumbing down in front of boys in case they won't date you, or spending all day thinking about relationships. High School wasn't a dating service. Now whether boys did better in single sex schools I don't want to think about. (I taught in both, but of course I am a woman and that changes the dynamic in both.) I didn't find this as true in college level teaching in California in the 90s. What changed? The role of women? The age of the students? Me?
