In one of my courses at a University, I overheard some of my classmates talking before a very difficult test (we knew it was going to be hard beforehand based upon the practice exam). The students were assuring each other that the department head "knows about the [stuff] going on [in this course]."
Apparently, several of them emailed or were planning to email the department head claiming, among other things, that the course material was too hard (grad level), the professor wasn't doing a good job, etc...
DISCLAIMER: I personally believe these claims are bunk. If any of these students actually attended the class on a regular basis, they may find themselves in a better position, IMHO.
My question is this: What, if anything, might the department head reasonably do? I ask because he's certainly getting a skewed, although loud, representation of the course. Our professor is new to the University, and I think is undeserving of such remarks.
EDIT: Changed asking what the department head might reasonably do so that an answer doesn't have to read his mind. :) @thecomments
