Why should I put on a front for my principal? Why should an appraisal be any different than any other day? I don't want to tap dance and put on a big show for her - I want her to see me for the teacher I usually am and I want her to see the lessons I usually present. Doing otherwise would be misleading to her and to my students. I want them to act like they do every day. I want her to appraise me for who I am and what I normally do.
If it turns out that what I'm doing in the classroom isn't what Ms. Taylor wants to see, then I'll change my way of teaching. At least I won't be acting for her or doing things that I normally wouldn't do.
