Recess is important... duh!

Anyone who has ever taught knows the importance of recess (or some sort of non-academic break).  However, it is nice to get some validation.  In today's NYTimes:
The best way to improve children’s performance in the classroom may be to take them out of it.

New research suggests that play and down time may be as important to a child’s academic experience as reading, science and math, and that regular recess, fitness or nature time can influence behavior, concentration and even grades.

The part that really jumped out at me was this...
Sometimes you need data published for people at the educational level to start believing it has an impact,”

Again, teachers have been saying this for years but why would anyone believe us :-)
