Sometimes it's worth stepping back and asking, "Does it actually make sense to put all children below a certain age in a big building for the majority of the day, where they spend all their time with other children of the same age, taking classes from teachers who serve as their only consistent contact with the adult world outside their own home?" Very few concepts of "education reform" are radical enough to ask that question.
Maybe it would be better if children spent more of their time in the company of adults in the real world, rather than in the company of each other in a kind of greenhouse-for-children artificially designed to raise them in a certain way.
Or maybe not; maybe after taking a step back and thinking big thoughts, we take a step right forward again and decide that schools as currently understood are what we're sticking with and any problems just mean we need better schools. But it's best to make that decision on the basis of a rational plan, rather than saying that Kids Belong In Schools because that's what the conventional wisdom was last year and we can't think of anything else.
