How To Improve Learning in Public Schools

[From article]
Anew study in the New England Journal of Medicine has a surprising conclusion. It finds that over the past decade, 1 percent of physicians accounted for 32 percent of malpractice claims. In other words, health care providers could eliminate one-third of malpractice and its associated health, legal and economic costs by removing the worst 1 percent of doctors.
It’s called the “law of the vital few” — better known as the 80/20 rule. It states that a disproportionate impact comes from a small input. Eighty-four percent of total income tax payments, for instance, are paid by 20 percent of earners. And more than two-thirds of all drunken-driving fatalities are caused by the tiny fraction of drivers with at least a 0.15 blood-alcohol level (the hard-core drunk drivers).

Perhaps nowhere is this rule more apparent than in the U.S. education system. Education economist Erik Hanushek has found that a small percentage of teachers are responsible for virtually all of the United States’ poor global education ranking. (U.S. students score worse on international tests than students from countries like Vietnam, Poland and Latvia.)
According to Mr. Hanushek, replacing the bottom 5-8 percent of teachers with average teachers could move the United States near the top of international education rankings.

It’s said that there are three ways people leave a job: some quit, others are fired, and some quit and stay. It is this last group that is most troublesome in any workplace. To solve this youth unemployment crisis and its associated ramifications, teachers who quit and stay must be fired.
But it’s easier said than done. Militant teachers unions like the American Federation of Teachers led by Randi Weingarten make it virtually impossible to fire the worst teachers. Less than 0.1 percent of teachers are fired each year in major districts nationwide. As a colleague of hers once said, “Randi Weingarten would protect a dead body in the classroom. That’s her job.”
The single most effective reform to make it easier to fire ineffective teachers is ending tenure, which virtually guarantees teachers jobs for life after as little as two years in the classroom.
