In my previous academic teaching appointments as a graduate teaching assistant, I've received nothing but excellent marks from my students and the professors that oversaw the classes. I even won an award for best graduate teaching assistant in that particular school of the college blah, blah, blah.
I just received my first student evaluation from a class that I taught at the rank of professor, without oversight, at a different university than I'm currently a doctoral candidate. Overall, they were pretty good, and I was at the university average or above it by most marks. I did have a couple comments that I was a hard grader who expected a high standard out of his students, so that was actually some helpful feedback.
However, I had one student who absolutely ripped me in the survey and comments throughout the entire evaluations. Of course, this student was a bad student and a problem throughout the semester. He could barely put coherent sentences together, and on three different occasions he questioned the fairness of my grading (calling me smug in the process), which he mostly misinterpreted anyways. He turned in many assignments late, even ones that I'd given him extensions on, and he regularly misquoted me, his classmates, and the text to argue things that he would later get points deducted for. Even in the poorly written evaluation comments themselves, he cited an example where he misread an argument and said that I was basically proselytizing for saying that he should justify his arguments instead of just stating them without argumentation. He was obviously the issue.
How worried should I be about these kinds of comments and ratings on my student evaluations? Even though it was really only one student that gave me negative marks, this being my first evaluation as a professor without oversight has me worried that it'll look bad on my record to even have one negative mark like that. I've talked to some of my colleagues, and apparently this kind of stuff is pretty normal, i.e. students who do bad tend to take it out on the teacher.
Does anyone else have any experience with this type of stuff that can give me some advice on this issue?
