I attended a public (coed) school, and I think that there are benefits you get from being with the other gender. If you split up boys and girls, you could be setting the children up for antisocial behavior later on in their schooling, and maybe into the rest of their lives. It may not be completely obvious, but I think there will be some discomfort for some students when they are re-integrated into a coed world.

There are plenty of chances to interact during recesses, lunch, before and after class activities, etc.
You should be in class to learn the subject.

We all grow up in a co-ed world - our family, for pete's sake. This is about keeping our kids protected, during their learning and formative years, from undue sexual and social pressures. They see the opposite sex under safer social conditions than co-ed institutions can provide. I went to a gender-segregated school and I've adjusted just fine, thank you very much.
