As everyone knows by now, there are districts that are eliminating recess and physical education because they want that time to devote to test preparation.

The test scores determine who will get a bonus, who will be fired, and whether the school lives or dies.

This is awful for children. They are active, growing, and in need of a break from study.

Now comes more evidence that physical activity is good for mental activity.

Actually, physical activity, play, unsupervised play is good in and of itself.

Whether it is walking, running, jumping, playing games, or just messing around, children and adults need time to engage in unsupervised activity.

This is the time when imagination runs free and children can be creative. They don’t choose a bubble; they aren’t stressed. They dream and imagine and live in other worlds than the one we have constructed for them.

Last year, I attended the Aspen Ideas Festival and I was invited to a private event where Secretary Arne Duncan spoke. The event celebrated the publication of a book by a friend of his who runs an organization called Kaboom. Kaboom enlists volunteers to build playgrounds; it has built over 2,000 of them. Secretary Duncan’s wife is affiliated with Kaboom (she was identified that way in the video introducing Michelle Obama at the Democratic National Convention).

At that Aspen party, Secretary Duncan spoke in a heartfelt way about the value of unsupervised play, the need that children have to “tinker” and make things without someone telling them what to do.

I was very impressed, but for the fact that only days earlier, the U.S. Department of Education had issued guidelines about testing children in kindergarten, first and second grades.

Please help me. How can one value unsupervised play time while judging children by test scores?
