I got a surprising email from the department chair today, saying that one student has made a complaint against me. It seems that heone of my weaker students felt that my tone in an office hour was mocking, and felt uncomfortable because of it.
My question to you is, what else can I do to get myself completely acquitted from these allegations, while staying professional? I think that maybe I'm overreacting a bit, but I also don't want to let the students walk all over me in such a fashion, especially if the allegation turns out to be unwarranted or false. I am quite young (younger than some of the TA's that work for me, actually...) and sometimes do have these authority issues in the classroom, where students see me as their equal.
Edit: just to keep the discussion relevant to my case, let's assume that it's clear from the chair's email that the student is very weak (my paraphrasing attempt didn't work as well as I had hoped).
Update: I met with the chair to figure out exactly what the complaint was about. It seems that the student (who I remember to be completely lost) did not like that I was not giving out answers (I conduct my office hours by posing small step-by-step questions for my students, and never give out direct answers, instead guiding them to the answer), and that I smiled while he felt lost in my office hour(!!). I expressed my regrets at the misunderstanding, and the rest of the chat consisted of the chair saying encouraging things to me, and that I should continue what I am doing with my students. Needless to say, I do not plan on changing anything.
It, but it is still upsetting to me that students can just fling off these wild allegations, though. From past experiences (with cheating) I know that students almost always win, since the onus is on the professor to prove that the student indeed cheated. In a situation like this, I feel that there should be a reasonable measure put in place, which requires the students to prove that the professor indeed acted in a problematic way, instead of making a complaint and asking the professor to prove that he did not do any of these things.
Anyway, thank you for your overwhelming support. Reading through your arguments, advice, and anecdotes really helped. I guess this was especially upsetting as it was my first time receiving a complaint like this, but as this won't be my last time (you can't please everyone!) I think I will be able to handle things much better next time.
