Overprepare is definitely something I do alot of. Also eliminate down time. I also try not to give my students too much credit. For instance, they probably don't think I'm doing as bad of a job as I think that I am doing at times.

Phones have been the biggest obstacle to my students who are inattentative. What I try to do is make sure that students complete their work efficiently before I allow them the "award" of being able to be on their phones.

I think one of the most important strategies for classroom management is several things that were mentioned in the text prior. I definitely believe in going over the syllabus thoroughly and have more often than not caught myself saying "it's in the syllabus" when asked a specific question about the course. I also believe that it is really important to set clear expectations from the beginning and let students know what to expect, and even when to expect things that may be more fun. This will promote a version of "buy in" that the text was discussing earlier.
