Oh dear, @Tiredallthetimelaura, not the sharpest highlighter in the box, are we? What a very silly bunch of comments. I have said on numerous occasions that I was a teacher for 47 years. An extremely successful one, in fact...the number of "failures" (a word I hate to use, as it simply means passing through the draughting gates of public exams), at Common Entrance and Scholarship, GCSEs, A Levels, including the Cambridge International A and A2 exams, I can count on one hand. Mostly As and A*s. One student in the Cambridge International A2 exam was top in the WORLD in Classical Studies. Not only an outstanding pass rate, but happy and fulfilled students. At Prep School, we played games. Running games, dancing, marching, battle re-enactments. Roman legions v. Barbarians in the woods after dark...resulting in occasional sprained ankles, scratches...you know, actual injuries. No-one cared. It's part of being a kid.
When I first came to the UK, I was shocked at how "pulpy" British kids were. Flabby, pale, over-protected, precious. Now I know why. They are not allowed to take risks. I notice though that private school parents are a great deal more accepting, and never make a fuss...Broken finger? Oh dear, well, he won't do THAT again.
Of course teachers can make mistakes - I just don't think the gross exaggeration helps. My son's yr 7 PE teacher refused to believe that his asthma was too bad to do cross-country, and forced him to run. He almost died. Now that is an issue to make a fuss about, and I did. Lessons were learned.
