As a student, I know that some lecturers just do a better job at getting their point across than others, consequently I would give them better feedback than others. I assume that teachers receive their feedback, so they know how popular they are with students. And presumably, they also talk about it with colleagues.
I imagine this to be a considerable source of conflict between academics, so I was wondering: How do those in a teaching role at a university/college/... deal with this problem? Does student feedback create awkwardness between colleagues, or is there some kind of unspoken law not to talk about student feedback?
