Part of the problem, I think, is that P.E. is not well taught at primary - and this may well be the case for secondary too. Lots of money is being put into it, but teachers need upskilling. When I trained to be a teacher I was only observed teaching P.E. once and received no formal training at all beyond observing a couple of lessons. However, I am supposed to be able to teach a range of sports to a good stabdard, including gymnastics, dance, netball, handball, hockey and tag rugby, to name but a few.
At the time that I trained -2007/8- lack of attention to teaching P.E. was typical as was seen as unimportant in relation to other curriculum subjects until fairly recently. With changing attitudes towards encouraging personal fitness and government concerns about an obesity crisis, schools are now being asked to ensure every child gets 2 hours P.E. a week and because more money is being pumped in greater attention is being paid to the planning and delivery. Of course, it should always have been the case, but the reality is that primary teachers are being asked to squeeze a 27.5 hour statutory subject allowance into a 25 hour week and something always has to give - and P.E. has been a poor relation for some time. With increased budgets, many schools are beginning to buy in experts, but if the teachers themselves do not have a good grasp of the games / rules I think there is a greater risk of accidents. I have had to learn as I go - imagine a vast field, 30 boisterous students and just one adult with very limited knowledge of the sport and winging it on common sense!
My DH was totally bemused and grumpy about the news yesterday - he was a keen rugby player to county level (prop) and feels that injuries were a minor problem in his day and all part of growing up. Mind you, although he still has a lovely nose and ears, his knees are shot and he has several broken and badly reset fingers ..!
