This is an excellent set of questions.  In combination with Quent's
observations on the lack of training of post secondary instructors in
evaluative methods, I see real deficiencies in my training.  These were
partially redressed by a several day inservice I took several years ago
called "targeted instruction" that I believe was a condensation of about 30
credits of course work in education.  It asked many of these same questions.
The instructor of the workshop referred to his colleages in the sciences as
"sorters" with respect to their (our) grading policies.  Upon reflection,
that was the goal of my grading.  Unfortunately, I think I hit *most* of the
pearls of wisdom of that 30 credit hours in that several day workshop -
i.e., (and this seems to be the feeling of my colleagues who have been
through those education courses) the other 29 credits (at least here) seem
to be busywork, restatements and eduational jargon.  I don't quite know what
to do with that (i.e., I think I'd lose my mind if I tried to audit some of
those education courses I missed), but . . .
