The process by which most teachers are supervised and evaluated in our schools is inefficient, ineffective, and a poor use of principals’ time. It’s based on a flawed theory of action: that supervision and evaluation will improve teachers’ effectiveness and therefore boost student achievement. I think the process drastically needs to be streamlined and be linked a more effective strategy for improving teaching and learning. I have not seen any teacher who told me that a formal summative evaluation changed his teaching style or improved her/his instruction.
