During my visit, several students told me that sitting on the balls while they work helps them concentrate. During the recent Minnesota Comprehensive Assessment (MCA) exams, students begged Hartman to try to change the start time of the test so they could get their morning workout in. They felt it would help them do better on the test.
They are used for positive reinforcement, the kids will do almost anything to keep their balls. I must say this a pretty innovative idea for a classroom and it is great to see teachers really thinking outside the box to create safe and fun learning environments for our kids to learn in - and throw in some physical activity too!
There is a nice video that goes with the article but it isn't embedable so you'll just have to go look at the site for yourself!
