Thomas Friedman in today’s New York Time column “Teaching for America”:

[Education Secretary Arne] Duncan, with bipartisan support, has begun several initiatives to energize reform — particularly his Race to the Top competition with federal dollars going to states with the most innovative reforms to achieve the highest standards. Maybe his biggest push, though, is to raise the status of the teaching profession. Why?

Tony Wagner, the Harvard-based education expert and author of “The Global Achievement Gap,” explains it this way. There are three basic skills that students need if they want to thrive in a knowledge economy: the ability to do critical thinking and problem-solving; the ability to communicate effectively; and the ability to collaborate.

If you look at the countries leading the pack in the tests that measure these skills (like Finland and Denmark), one thing stands out: they insist that their teachers come from the top one-third of their college graduating classes. As Wagner put it, “They took teaching from an assembly-line job to a knowledge-worker’s job. They have invested massively in how they recruit, train and support teachers, to attract and retain the best.”
