I am going for an interview for a long term supply teaching role very soon (this week). In your experience, what are the main things that I need to show in an observation? I am clearly doing something wrong as usually I don't get the jobs. It is deeply depressing. The last comment was "nice lesson, I really liked your resources" but i didn't get the job. It was really demoralising. I generally get very good references when I am already working in a school but in the interview/observation process I seem to develop a set of "horns" and scare off the job prospect. Any advice? I am well dressed and present myself well. I try to be friendly but somehow it goes "pear shaped" in that 30 minute observation. Any advice would be great!
