tl;dr: professor has a few bad experiences with students and, combining them with a choice anecdote from an unnamed colleague, proceeds to generalize to not only the (presumably) hundreds of students he has taught, but students, everywhere, in general.<p>Having been a student myself, I <i>could</i> recount the time when a professor chose to replace her all twelve of her lectures with student presentations, then tested us on entirely untaught content; or perhaps the other time when submitted assignments and tests were not marked or discussed, at all, so that the only feedback was a numerical result at the end of the semester.<p>I <i>could</i> choose to say that this is symptomatic of a system where research is king and teaching is for peons and undergraduates are lower than dirt.<p>Or I could choose to say that perhaps some professors are just bad at their jobs.  Or, even, they just had a bad semester.  The advantage is that I could do this without cherry-picking the outliers.<p>What did the writer teach?  I hope it is not statistics.<p>edit: that&#x27;s some fast negative karma there.  Those of you that downvoted, I would love to hear your thoughts.
