As the wife of a former PE teacher (he now teaches Biology), I was stunned by how little PE is required where we live in Georgia. In Anchorage, our school district required PE through middle school/junior high (Mark taught middle school PE and they actually *did* real PE -- played volleyball, basketball, ice hockey in the winter, baseball, aerobic dance, running, etc. -- real physical activity every day), and a certain number of PE credits and passing some fitness tests (including a swimming test) was required in order to graduate from high school. The elementary schools also had two recess periods per day, and the kids went outside in the winter until it got below either zero degrees or 5 below zero (I can't remember which) -- we had to make sure they went to school in their snowsuit, gloves, hat, face mask/scarf, and snow boots.
Where we live in Georgia, the elementary school kids have PE three days per week (not sure how long the PE period is), one 15 minute recess per day (and on hot or rainy days they don't take them outside at all), and middle school PE is a 9 week class that the kids gets rotated through a minimum of once during their three years of middle school. In the high schools, kids are required to take one semester of "personal fitness" in order to graduate -- and all my DD's class did was walk the track every day and do some stretches. They also had to run the mile three times during the semester in a certain amount of time. Not much of a PE class.
And they wonder why Georgia has such high rates of childhood obesity...
Physical activity isn't just important for physical health -- it's also important for emotional and mental health. Not to mention it has a positive impact on behavior!
They really, really, really need to do a complete overhaul of the education system in Georgia -- PE would be a great place to start. (And I don't just say that because DH was a PE teacher and is now a high school coach!)
