This highlights one of the problems I have with the blogospheric response to the Gladwell article. Far too many people are taking the article as evidence that we need to enact all the favorite union-busting “reform” measures that have been proposed, starting with the elimination of tenure for teachers.
The problem is, that’s not the right message to take away from the article. The point of the article is that it’s hard to know in advance who’s going to be a good teacher. It’s actually not that hard to tell who’s good and who isn’t once they get in the classroom, though.
Take a look (at the comments too!).
