Hi Pandora:
Ref Extra Credit on exams. I think every teacher and institution has to determine what they think works best for the school and or the the class. Many institutions simply don't allow it. Many teachers won't either, usually freom poor past experiences and the net effect oin student learning.
Now maybe it's semantics, but I think there is a difference in extra credit, where students simply get awarded points for really nothing actually assigned with the purpose of raising a grade. To me, thats not fair.
But say, an essay question on an exam may have a bonus… >>>
