I hated most of my P.E. classes. If they had been truly physical education classes, I might have gotten more from them. As it was, most of the classes focused on team sports, and the teachers picked the best athletes in the class and had them pick their teams, alternating. This method was, I feel, guaranteed to demotivate the kids who were already less athletically inclined. This set up the clumsier and less athletic kids up for automatically failing to improve. The result (at least in my experience and the experience of my friends) was to turn out kids who hated the notion of physical activity and who would quit doing it as soon as they could.
I think that a true physical education does have a place in a school’s curriculum, though it shouldn’t just be going out and playing basketball (or whatever) for 45 minutes a day. There should be two parts of the class, one in which the students learn about health issues and physical safety, and one “lab” session, in which the students actually go out and exercise.
For the most part, the exercise/sport sessions should consist of things that the students can use in their adult lives…things like weight training, cardio exercises, stuff like that. Advanced students can substitute basketball or football or other team sport for their PE requirements. Every student should know how to get exercise on his/her own, though, without a team.
The classroom part of the PE should intruduce proper meal selection, nutrition, disease prevention and how to take care of oneself when one DOES get sick, and first aid, at a minimum. I’d also like to include human sexuality in this, but that’s a topic for another thread. My daughter had to take a few health classes and became MUCH more motivated to eat a healthy diet, and the whole family benefitted.
With this two pronged approach, I believe that we could reverse the tendency towards obesity, and generally live better lives. The P.E. classes that I was in were worse than useless, they were detrimental to me. I would have been better served with a study hour than to have gone to most of those PE classes. I did do a lot of walking back then, which kept me in pretty good physical condition, though it didn’t improve my dexterity.
The arts are really too varied to cover. Are we including music? Drama? Language arts? Just about all of them will teach a student to think and learn. In music, particularly, the student will learn teamwork, discipline, and all the other good things that the OP claims will result in a good sports program.
