JOHN STOSSEL ON THE COMMON CORE CONTROVERSY:

This may sound good. Often, states dumb down tests to try to “leave no child behind.” How can government evaluate teachers and reward successful schools if there isn’t a single national standard?

But when the federal government imposes a single teaching plan on 15,000 school districts across the country, that’s even more central planning, and central planning rarely works. It brings stagnation.

Education is a discovery process like any other human endeavor. We might be wrong about both how to teach and what to teach, but we won’t realize it unless we can experiment — compare and contrast the results of different approaches. Having “one plan” makes it harder to experiment and figure out what works.

Some people are terrified to hear “education” and “experiment” in the same sentence. Why take a risk with something as important as my child’s education? Pick the best education methods and teach everyone that way!

But we don’t know what the best way to educate kids is.

As American education has become more centralized, the rest of our lives have become increasingly diverse and tailored to individual needs. Every minute, thousands of entrepreneurs struggle to improve their products. Quality increases, and costs often drop.

But centrally planned K-12 education doesn’t improve. Per-student spending has tripled (governments now routinely spend $300,000 per classroom!), but test results are stagnant.

“Everyone who has children knows that they’re all different, right? They learn differently,” observed Sabrina Schaeffer of the Independent Women’s Forum on my show. “In the workplace, we’re allowing people flexibility to telecommute, to have shared jobs. In entertainment, people buy and watch what they want, when they want.” Having one inflexible model for education “is so old-fashioned.”

That’s pretty much my philosophy in my new book on education.
