Unless they were absolutely terrible, professors received a standing ovation at the end of the quarter. Feel like this is tradition, no?
I guess I'll be the first one to point out that I never witnessed anything like that.
I was a TA for many classes during my Physics PhD program, and this bit of clapping was a singular occurrence, in the middle of the semester. I’ve never been a course lecturer though, that was always for faculty.
The OP at first glance seems to be pushing an incorrect assertion ("standing ovation common at end of quarter unless professor was terrible"). I am slightly amused that over half the current set of comments to this entire article is bewilderment and confusion caused by taking the OP seriously.
