I was observed recently for a portion of a lesson by a member of SMT. I was given no notice of any observation, nor were any observations or learning walks (or any other obs by another name) calendered. They arrived at the start of said lesson, entered my room and asked if they could sit in for a while. Obviously I was not about to say no and send them packing! They left after about 20min and i continued the lesson. I later discovered that an observation sheet had been filled in for the portion of the lesson that was observed, although I only discovered this as I actively requested feedback as none at all had been offered. I didn't think much of it at the time but the more I think about it, the more wrong it seems. Not only the way it was carried out but also the fact that there is written evidence being kept from this impromptu observation. I feel as though someone was trying to catch me off guard an that this was certainly far from a supportive use of the observation process. What are your thoughts?
