Next week I begin one week of classroom observation. I have organised this to help with my forthcoming applications to Initial Teacher Training. I have never been in a classroom since I left school at 18. My degree is in Physics, my MSc is in Computer Studies, and I have over 10 years' commercial experience. I want to get as much as possible out of next week, when I will be sat in a range of secondary classes observing (and possibly joining in) Physics, Science, and ICT. What do you recommend my objectives might be? How do you think I should prepare for next week? Many thanks in advance. Rich.
