Same sex classrooms?

I was just reading on another middle school teachers blog about the survey done asking parents what they thought of same sex classrooms.  Most thought it was a great idea.  Being a middle school teacher and a mother of two teenage boys I too agree that same sex classrooms would eliminate a ton of behavior problems.  What I see in my day to day teachings are students that try to impress and show off in front of opposite sex students.  They say things that get them in trouble and do things that should not be done in school just to impress the opposite sex in the classroom.  Although public schools might have a hard time implementing this concept other private schools have already seen the benefits of this type of schooling. The dynamics between opposite sex students is interesting and by making same sex classrooms it could turn the students focus back to the school work at hand instead of the other students.
