I've been asked to lead a one hour session to various teachers form around my college. Generally I'm a confident teacher but this fills me with absolute dread. It's about giving a general "acting" lesson so that we can share good practice and they can give me feed back. I have no idea what to teach. I'd be much happier having them observe me with a class of students, and there is so much to pick from with only a little time, i'm not sure what to do. Any suggestions would be very gratefully recieved!
