My experience was that what passes for "socialization" in k-12 school is extremely weird compared to the same among adults. I wouldn't rule out that it is nonetheless somehow important to kids' development in a way other approaches aren't, but my gut feeling is that socialization among adults and a range of peer students of many different ages rather than mostly the same age +/- one year (how the hell, exactly, is one supposed to model the behavior of socially-successful older kids when one is rarely around them, or easily notice one's own failings when not exposed to amplified versions of the same in younger kids?) would be far better at turning out well-adjusted people.
