I have found that when I have forgotten or been a bit flustered and changed the order in which I began class on the first day, it does not run as smoothly as it would have. Also, I don't get as much feedback from students. This is a simple thing, but very key in starting out with your students on a good foot!

Agreed! I also find that I have used these terms and jargon for quite a while now, but with them giving an in depth definition, I am better able to apply them to my teaching strategies.
