I'm wondering how others would respond to this scenario: Your admin tells you that parents and students have complained about some aspect of your teaching. You don't know who or why the parents haven't addressed the issue to you directly. You are taking steps to fix the problem, but its a process and in the meantime, from time to time, you hear similar complaints. I'm not being more specific because it's not about a particular issue, but any issue. Just think about what your weakest area as a teacher is and imagine it's being harped on continuously. Obviously you need to develop some confidence to proceed, and you can't respond to anonymous complaints. What attitude would you take?
