What Makes a Great Teacher?

How can one evaluate who will be a great teacher? That’s the question posed by journalist Malcolm Gladwell (author of The Tipping Point) in the current issue of The New Yorker. He says, in part:

Eric Hanushek, an economist at Stanford, estimates that the students of a very bad teacher will learn, on average, half a year’s worth of material in one school year. The students in the class of a very good teacher will learn a year and a half’s worth of material. . . . your child is actually better off in a “bad” school with an excellent teacher than in an excellent school with a bad teacher. Teacher effects are also much stronger than class-size effects. . . .

After years of worrying about issues like school funding levels, class size, and curriculum design, many reformers have come to the conclusion that nothing matters more than finding people with the potential to be great teachers. But there’s a hitch: no one knows what a person with the potential to be a great teacher looks like.

Gladwell then cites an impressive group of researchers who have found that teaching certifications and master’s degrees, while required in almost every district, don’t make a difference in the classroom. The only way to find good teachers? Watch them teach, then evaluate them. The implications, as Gladwell sees them?

[Teaching] needs an apprenticeship system that allows candidates to be rigorously evaluated. . . . Currently, the salary structure of the teaching profession is highly rigid, and that would also have to change in a world where we want to rate teachers on their actual performance. An apprentice should get apprentice wages. But if we find eighty-fifth-percentile teachers who can teach a year and a half’s material in one year, we’re going to have to pay them a lot—both because we want them to stay and because the only way to get people to try out for what will suddenly be a high-risk profession is to offer those who survive the winnowing a healthy reward.

I have to think there’s some truth in what he’s saying, but education is a complex topic. What do you think of Gladwell’s analysis? Are statistical averages meaningful? Is he overlooking any factors (like parental involvement)? Is his solution practical? Thoughts from educators in the audience (or anyone else)?
