I agree with Yglesias' basic suggestion that the overly long summer vacation for kids, at least for the younger ones, is an anachronism. Having said that, I wouldn't support sticking kids in barely air conditioned classrooms for more of the same over the summer months, but instead spend a couple of months with more of an "educational summer camp" model.
But, given that I have no kids and no experience teaching the young ones I have no idea what I'm talking about.
