Quote of the Day (with apologies to Diane Ravitch)

One of the reason Honda and Toyota ate General Motors’s lunch is that the Japanese car companies adopted statistical quality assurance while Detroit was still inspecting every part coming off the assembly line to see whether it was within tolerance. Why are we using those same outdated principles to manage the much more complicated problem of teaching children to read, write, and reckon?
