It Turns Out Kids Don’t Learn More in Small Classes
In light of the Ontario government's expensive initiative to reduce class sizes in the primary grades by requiring a maximum of 20 students per class, the failure of a similar initiative in Florida bears close scrutiny. By a legislative quirk, one group of school districts was forced to reduce their class sizes by an average of 3 more students than a different group of school districts - making it easy to compare test scores in the two groupings. It turns out that there was absolutely no detectable benefit to reducing class sizes, and that the huge amounts of money involved in class size reductions might be more profitably spent in other ways.




I’ve always been curious as to why the class size issue is presented as if there is one, single class size that “works best”. I don’t think I buy that. I have a feel the optimal class size has something to do with who is in the class. It wouldn’t be a stretch to imagine a class of 30 achieving, “typical” kids who were easier to teach than a class half the size made up of kids with exceptionalities.
In other words, is the issue the size of the class or is it the diversity of needs and learning profiles within the class?
