get rid of skorts, shorts and short skirts for girls. Bad enough having your body on show and then maybe having to deal with a period.
Split by ability for PE / sport rather than just age, I mean the whole school year as they do with maths and MFL.
Allow kids to substitute sport outside school for PE lessons. I hated PE but outside school I was doing Karate, Ju-Jitsu and swimming.
Have lessons where the individual can improve fitness eg aerobics or dance.
Don't assume the fat kid is unfit.
Don't pick captains and then allow them to pick the team.
Devise games where everyone in a team / group can take part and the group cannot win without everyone doing something, preferably something the less sporty can do WELL, eg an obstacle course where half the team have to go over an obstacle and half under but which is actually designed for a wheelchair user to get under faster than the sporty ultra fit child.
Everyone loves a game of rounders. Just a thought.
Yeah standing there swinging a bat that misses each time then been sent to stand as far away as possible so the only time a ball comes near you is when it is really important but no matter how hard you try you cannot catch it.
Yep that ritual humiliation is fantastic for teenage girls.
