I do not understand why teachers are so intimidated by observations, evaluations, and in particular casual, unscheduled walk-through observations by their adminstrators or colleagues. In any given profession, you are observed by others in your workplace, whether by your superiors or constituents.
Teaching is one of the few jobs where adults work in isolation, with no accountability to anyone else for their daily tasks. Our students are left at our mercy, behind closed doors. They have little idea if they are being taught what should be taught, if it is truly preparing them for the next step in their lives or not.
It seems to me that teachers should open their doors to each other, to their adminstrators as well as parents. If we are doing our job, we have nothing to hide. By opening our doors, by welcoming honest feedback on our 'performance', wouldn't we simply be encouraging ourselves to look critically at our own practice and how it can best be improved?
Maybe that's part of the problem? Some teachers are so entrenched in their own mediocrity they are afraid of having to improve?
There are many great teachers out there with much to share - content, pedagogical methods and styles, organizational tips and tricks - with their colleagues. Walk-throughs of each other's classes could share the wealth of knowledge, creating a more effective place of learning for students. We just have to get past that initial cringe of fear of having others in our rooms.
