NOTE:  These rules of conduct apply to all classes I teach.   Courtesy and Respect for all opinions expressed in the class is required.  You can disagree with someone's position, but you must do so politely.  Criticizing the human being for his/her opinions is absolutely not allowed (as in "you're stupid to think that way" -- uh uh, don't even go there!).  Polite disagreements begin "I see your point, but....".  This rule extends to noises, grunts, sighs, eye-rolls and other mannerisms and body language expressing disrespect.    Cell phones, pagers, and other electronic noisemakers must be turned off before you enter class.  I reserve the right to confiscate offending devices for the remainder of the class period.  The class as a whole reserves the right to stare at the offender until order is restored.  If you have an issue and are expecting an urgent notification, see me before class.   Sleeping is absolutely not allowed.  If you nod off in class, you will be rudely awakened with a very loud noise, asked to leave the class, and marked as absent.  If you are experiencing issues interfering with your body's requirement for rest, consider dropping the course, or taking the day off -- with the usual absence penalty, of course.  Sleeping is a sign of disrespect -- toward me and your fellow students.   No food is allowed in the classrooms.  Food crumbs attract cockroaches, and the munching and crunching, as well as the crackle of wrappings, disrupts the class.  Beverages are allowed, as necessary.    Laying your head on your desk is not allowed.  To me, it's the same thing as sleeping. Once you enter the classroom, do not leave until I dismiss the class.  Go to the bathroom before class begins.  If you have an issue, please consult with me before class begins.
