grades are a very touchey subject. The kids want to know how they have done
and you must tell them. If you had given them the Objective of the unit to
begin with, they would have few questions of their grade except to see how
they have completed the objective. I always have a minimum objective in order
to get a C. Then, if they want a better grade it must be asthetic and
craftsman like in order to get a better grade. When we have a critique I
state how the grade was determined and they should see that they are based on
the primary objective and then on their own response to the assignment. I
don't use ruberics but I use the numbers, 200pts, 100pts etc. per assignment.
they have a written critique in which they can write about the art and this
will help their grade. I work on a percentage based grading program.
