"In thinking about my past week teaching what is one thing I would do differently, and why?"

     As of late I have been thinking about what we learned in NTI this Summer, and all the elements that I wanted to incorporate into my classroom this year.  While this year has been much better than the last, I still feel like I am falling short in certain areas.  My colleague had surgery at the beginning of the school year and getting substitute teachers is something close to an act of Congress.  Needless to say, I have inherited his classes, and I'm not complaining but it is hard to provide the attention and structure my actual classes that way I want.   
     Looking back at this last week and in preparing for the future, one thing I want to do differently is my response to behavioral disruptions.  I haven't completely lost it, but I've noticed some sarcastic responses of mine when trying to manage both classes.  As a result (behavior breeds behavior) I have received some sarcastic responses from students.  I talked to them after class and we came to a mutual understanding, but those are talks I want to avoid in the future.  Using the language of choice seems to work pretty well, however, proximity control works on very few at Clarkston High School.  Classroom management, specifically responding to behavioral issues, is what I plan to change starting next week.
