I'm not sure how observations work at your school, but we have one formal observation each quarter (grading period) and walk-through evaluations at our principals leisure. I know that I am not a perfect teacher, so I really do like when my principal comes in because I think she gives good feedback about some of the things that I might miss in my classroom. Anyways, one of the requirements (or checklist items to look for) in our classrooms is that we are displaying student work. This year I have THE FRIDGE. I found the idea on Pinterest and immediately fell in love. The students can hang things that they are proud of up on the board. I have lots of A+ math tests, a few tests/quizzes from other classes, some principals list certificates, a college acceptance letter, and even one drug & alcohol class certificate (that one you have to take before you can get your learners permit). All of these are small sentiments of my students and the things that make them proud. I love it ...
