I still think you're missing the point, Pavonis. It doesn't matter what you're called. You're behaving as if these students are going to be crazy hormonal teenagers that are incapable of discipline. They're in college now; they deserve to be treated like adults. They will still be immature, especially if they're undergrads, but you have to treat them like their purpose is to learn. This isn't like high school where they're forced to attend and will act out because they're bored. They chose to go to college. You're worried about them respecting you, but I already get the feeling that you don't respect them. The main point I'm trying to make is this: you're the one that they are going to be addressing. What do you want to be called? Because I guarantee that they don't care either way. The level of respect you receive will be based on the kind of teacher you are. Respect based on title is purely artificial and ultimately meaningless.
