What I've been saying for a while

I've been saying for a while that current educational fashions are at least as much about cultural resonance as they are about studies showing learning gains of X percentage at whatever level of statistical significance.  Well, this op-ed by a history professor says the same thing.

When educational trends are being criticized in an op-ed in the New York Times of all places you know that something very strange is happening.  What's next?  Human sacrifice?  Dogs and cats living together?  Mass hysteria?
