The main findings: The more play a school gives its student body, the greater rewards kids see in their character development, academic achievement, safety, and overall health.
According to Vialet, structure is a child's best friend when it comes to play. While kids may have a built-in urge to run around and get dirty, playing with other kids is a social experience, which means it has to be learned.
A 2013 study of the Playworks model from Stanford University found it led to 43% less bullying, 20% higher feelings of student safety, 43% more physical activity, and 34% less time transitioning from recess back to the classroom. A number of other studies suggest recess can also lead to better grades in school, regardless of the form it takes.
