Classroom Etiquette

One would think that at the college level a list such as this wouldn't be necessary, but apparently some students are unaware of some of the basics of classroom etiquette.   There will certainly be variations as to what is considered "proper" for a class based on the nature of the course.  There will even be differences in a particular course depending on what is occurring at any given time (lecture, discussion, group work, test, etc.).  Thus, the list below should serve as a guide rather than a strict set of rules.
