If for some reason you must leave early, be courteous and sit close to the door so your departure doesn't disturb everyone else. This allows you both to benefit from class time and to contribute to the learning of others. Packing up your texts and notebooks before we are finished is disruptive and rude. Be courteous and give your full attention to the work at hand until I dismiss you. Don't come to this class planning to do work for another class.
Group work is intended for specific purposes, namely productive learning.
If you do not contribute to the group in which you participate, you may be asked to leave. Food, gum, and drinks are permitted in the classroom, but be considerate and quiet. And please take the time to dispose of your garbage when you leave. If you have questions about a grade you've received, please talk to me privately. It's unfair to your classmates to take their time to discuss your grade.
