Each teacher is different. Everyone uses a different approach, behaves differently, has his/her own ideas, activities, and games. I believe that the observation of another teacher is a very useful tool for teachers´ development. The observer always finds new inspiration and the teacher observed gains feedback about things that he/she may not notice or reflect during the lesson. The observations don´t require evaluation or criticism but they provide the opportunity to think about the teaching process and about options and ways to improve it.
