Hi Gerd,
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.
