Thank you so much to all for your thoughtful replies...I really appreciate it! I actually won't be on campus until the fall as I live on the opposite coast...Should I initiate a meeting via email or do you normally meet the week before with the professor? Are TA's normally provided the texts for the class in advance and free of charge? I think I will simply be leading discussion sections, attending lecture, and maintaining office hours, but now I'm wondering if there is more to it than this....It sounds as if most of you have had much more responsibility than that...I didn't realize that TAs were actually teaching classes, by which I imagine you are presenting lectures, etc? Also, I am a woman, and I'm wondering your advice on getting problematic students to behave. Do you ignore them? Call them on it? On the first day of class (in my case, discussion), how did you introduce yourself? Also, how did you respond to questions to which you didn't know the answer? Lastly, what kind of dress code should I follow? Thanks again for your advice...You have NO idea how valuable it is and how I much I appreciate it!
