Interesting how the public school "reform" movement in the US cuts hard against this sort of experimentation --- in particular, by mandating curricula, and evaluating students and schools by performance on cookie-cutter tests that make no room for individual interests or variation.
Not really. That is not intrinsic to the reform movement. That is the educational system responding to political pressure. The reformers have to play the game by the rules as they exist in the moment. If the standardized cookie cutter test results become the coin of the realm, then every kind change will be justified by test results, whether the proponents think that is a useful idea or not.
