My son's Kindergarten teacher sent this article home today. "Playing to Learn" on the New York Times website.
I particularly liked how in the ideal theoretical classroom:
"During the school day, there should be extended time for play. Research has shown unequivocally that children learn best when they are interested in the material or activity they are learning. Play — from building contraptions to enacting stories to inventing games — can allow children to satisfy their curiosity about the things that interest them in their own way. It can also help them acquire higher-order thinking skills, like generating testable hypotheses, imagining situations from someone else’s perspective and thinking of alternate solutions."
