Have you tried just sitting down and talking with them? Maybe what is micro managing (and I HATE to be micro managed) is really just an a poor attempt at trying to learn and understand the workings of an elementary school and the classes you teach. It may be that their lack of knowing is creating insecurity on their part, so they are knee jerking and over trying to manage. Just a thought. Be real and graciously honest - I've been doing this and I know there are other ways to do things but what I've been doing is successful and this is why I do it this way. I'm glad you're here and want to hear your ideas, but it would help me for you to hear mine as well and the whys of what and how I manage my class and subject. If they feel like you are willing to hear them and want to work with them the year could turn around for you they will maybe come alongside you instead, and you could be a huge part of training up this new admin....maybe.
