Diana Senechal has written a thoughtful reflection on the tendency of policymakers to foist big ideas on education. Fads come and go. The ones we live with today, say I, seem especially pernicious because they are backed by the power of the state in alliance with the profit motive.

Yet I remain confident that truly bad ideas will fade away. This is not from a sense of resignation or historical inevitability, but because I believe that educators and parents and school boards will rise up and say “Enough!” It is beginning now, and the roar of protest will grow.
