Those who can’t teach, pass laws about how to evaluate teachers.

Congress and state legislatures should not tell teachers how to teach, any more than they should tell surgeons how to perform operations.

What is happening to teachers now across this nation is a disgrace. The attacks on them are a blot on our nation. Teachers and students are not different interest groups. Anyone who demeans teachers demeans education and hurts children.

Testing children until they cry is a bad idea. It is an educational malpractice.

I support charters, but the right kind of charters. I support charters that support kids who have the highest needs. A charter should be targeting students who are in serious trouble. It should serve students who didn't succeed in public schools when it can help them. Or, at least, charters should agree to accept similar proportions of the kids with the highest needs.

Most people believe that schools were good enough when they were children and that they are good enough now. But the dynamic growth of our system of education has spawned serious problems of educational quality.

What should we think of someone who never admits error, never entertains doubt but adheres unflinchingly to the same ideas all his life, regardless of new evidence? Doubt and skepticism are signs of rationality. When we are too certain of our opinions, we run the risk of ignoring any evidence that conflicts with our views. It is doubt that shows we are still thinking, still willing to reexamine hardened beliefs when confronted with new facts and new evidence.
