Can you not sit down with a member of staff at the school or your tutor to ask advice & way's ti improve? In asking for help, it would show that you understand your area of weakness and a willingness to do something about it. Think back to when someone inspired you to do something out of the ordinary, and work through, why that approach worked. In what way is it different to they way in which you plan lessons? Never be afraid to ask for help, that's what your mentor is there for? Have they said anything to you about it?
