Hand Gestures Dramatically Improve Learning..

Kids asked to physically gesture at math problems are nearly three times more likely than non-gesturers to remember what they've learned.

In today's issue of the journal Cognition, a University of Rochester scientist suggests it's possible to help children learn difficult concepts by providing gestures as an additional and potent avenue for taking in information.

"We asked if the reverse could be true; if actively employing gestures when learning helps retain new information."

It turned out to have a more dramatic effect than Cook expected.
