I'm curious and concerned about this because I taught for the first time recently, and suddenly had to confront just how hard it can be to try to mark. I realise that I really don't know what to expect from students, and it doesn't help that I went to school in a different percentage system (in Canada, an 80 seems to be similar to an American 90, and a British 65). What does an A or A- mean, in terms of quality of work? Or a B or a C or D? How can you have high standards, without having unreasonable ones? I know a really good and a really bad paper when I see it, but it's the bordering ones that I agonise over. In the end, I ended up with an average a little higher than I was really comfortable with, but not that dissimilar than other TAs in the same course. I know that there are a fair number of teachers here, university and otherwise, and I was wondering if you could share your advice.
