Whining

I'm grading midterms.  It's as depressing as ever.  Not that some of my students aren't doing well.  Some are doing very well.  It's just that Platonic ideal issue again.  I have this idea, see, of what the class is learning...and all through the semester they seem to be learning that...and then here come the midterms and what the class has actually learned...

Obviously I should not be a teacher.  Obviously an exciting career in drywall installation awaits me somewhere.  Or paralegal research, perhaps.
