In a series of stories beginning today, NPR’s Education Team explores the concept of play and how it relates to learning. What is play? How does it help us learn? What kinds of play are most effective? The stories air through August 10 on NPR’s newsmagazines and on the NPR Ed blog. Listen in on Free and Wild Playgrounds, Playing to Win, Science of Play, Grownup Play and more. Tune in weekdays from 5 to 8 am and 4 to 6 pm on KUAC FM, KUAC online, KUAC HD, and KUAC TV 9.5.
