I hate to admit this, but I think I am getting burnt out on teaching. Not at the graduate level, but at the undergraduate level. I say "they are getting younger and younger," but it isn't that I can't relate to them or keep up with them. What bugs me is the (admittedly small) proportion who just don't care and make no effort. This type of student has always been present, but it bothers me more now. Why would someone (fairly) consistently come to class, but make no effort and do no work? I have five small five point assignments due throughout the semester. Why would someone just not hand them in? Four of the five are done at this point -- so this is a loss of 20 points already. I don't get it.
