The importance of micro-teaching

I am sure that every teacher remembers his/ her first year of teaching,  during this time every experience represents new knowledge, challenges and opportunities to improve. Young teacher, during their first year, are characterized to be aware of every decision they take in the classroom, they  question their own practice and ask more experienced teachers for advice. When a teacher starts his/ her career is not afraid of been observed or receive feedback. As years go by, teacher's confidence increase because he/ she develops a teaching style with which he/she feels comfortable with. Therefore teacher starts to believe that his/ her way of teaching is the most appropriate and rarely is eager to make changes.
If we think about it, this situation is inconsistent since the more we are involved in teaching, the more  we would be able to adapt and change. However it seems that experience only keeps the teacher in his/ her comfort zone.
I consider that one way of improving this situation it is the micro-teaching. I read that this strategy is is mainly used to train pre-service teachers however I consider that it is an enriching experience for  in-service teachers. This strategy consists in having teachers designed a lesson of 5 to 7 minutes in which principles for language teaching are demonstrated. Teachers present this lesson to  a group of teachers who participate in the lesson but also analyse the goals, strengths and challenges. Besides, this is a way to spread ideas among colleagues.
In the place where I work, teachers get together to discuss and analyse academic goals in meetings called C.T.E. Although this meeting have academic purposes, they sometimes are used to criticize and judge teachers or students and analysis and reflection rarely takes place. I would like to implement micro-teaching in my school zone since it will help novice teachers to gain confidence but most importantly to challenge experienced teachers to think differently and reflect in their own practice.
