This was my experience of PE in high school:
10 minutes faffing about in the changing room
25 minutes of:
1st Quarter-Aerobics
2nd Quarter-Square Dance
3rd Quarter-Sports
4th Quarter-Running
10 minutes faffing about in the changing room
At the end of each quarter we’d be required to attempt a certain number of sit-ups, pull-ups, squat-thrusts, etc, having to do with some sort of presidential fitness program. The only ones who ever succeeded were those getting their fitness training elsewhere, usually extracurricular sports. The rest of us, having no training, would naturally do poorly. At the end of the year, they’d work us nine weeks til we could run a mile in under ten minutes, mostly succeed, and consider the year a job well done.
In other words, they taught PE just like they taught every other subject....
Your summary reflects my experience too.
