Smaller class sizes? How about better teachers?
From a recent edition of the The Hechinger Report:
The question isn’t whether class size matters. Of course it matters – at the extremes. Elementary students in classes of 50 would almost certainly learn a lot less than similar students in classes of 10 or 20. But what we’re talking about in the U.S. is marginal reductions to class size, going from 30 to 25 students per class, and the benefits versus the costs of such reductions.
The real question is whether across-the-board, marginal reductions to class size are a sounder investment than any number of other reforms we could try. That is, is reducing class size a move that yields a disproportionate bang for our buck? Decades of research suggest the answer, sadly, is no. Investments in teacher quality would do much more than smaller classes to raise student achievement in the U.S.
