I am also going to point out that some people just seek to make changes for progression/improvement sake. As long as it' not done in a way that is insulting to others, then I don't see what's wrong with it. I can't tell you how many ideas/proposals I have sent to my coordinator, and at times unsure how those ideas/proposals will be accepted. I submit them anyway because I strongly feel that we should constantly seek to improve, and if I have an idea that might help improve the quality of a student's education, then I will run the risk of upsetting my coordinator. To me, it's worth it. And, a couple of my proposals have already been implemented at my current school, and that makes me feel like I am actively making a difference.
