Hormones in year 9 were often problematic in my sec school teaching at first, but I reconstructed the PE curriculum based on their preferences & gave them lots of choice. The behaviour issues pretty much disappeared. Be a flexible teacher & curriculum designer. Listen to kids 🙏
Here are the secondary answers to “which year group is the most challenging to teach” question I asked a while ago. As I’ve never taught in secondary, I don’t know what the reasons are, but would be interested to hear your thoughts.
