[LON-CAPA-users] Portable Exam Scanner
Tue, 25 May 2004 09:08:06 -0700
We are typically looking at up to 300 students with a test or quiz conducted
within a 50 minute period, in an congested space. This seems unworkable to
me. Any kind of feedback to students is going to be a problem. We have
trouble getting them out of the room for the next class or exam as it is.
I'm not sure I understand the rationale that says that it is a good thing to
grade the quiz on the spot. Without feedback of a specific nature, there is
no learning benefit to the student. Merely gratification.
I can't help but feel that this is not a bread and butter issue...more like
icing. There's still some pretty doughy spots elsewhere that could do with
some baking. No doubt, I am missing the point?
And that's my 5mL of cold water... now back to couse management and homework
issues...or perhaps a good long break.
