I agree that an instructor is most successfull if he/she creates an environment where students feel safe to ask questions and positive discussion is facilitated by sking open ended questions. I have encountered some students who have very negative attitudes and often feel that it is difficult to stay on track and redirect when confronted with sarcasm and negativity. What other strategies can be used to manage the classroom, and guard against negativity, in addition to addressing concerns with students one on one?

I feel that supplemental materials provide opportunities to engage more students in the classroom. Especially if not everyone is as comfortable with the textbook authors style of delivery. I am looking at utilizing articles from Time Magazine in class but I want to be sure that I, in no way, will be in violation of copywright laws. If i am sure to provide all appropriate citations and credits, can I make copies of articles for classroom use?
