Gradebook

Since I made my initial post, I have learned a few things about the "sum of grades" aggregation method.  I thought I'd share in case anyone else has had the same questions that I posed.  The faculty grade book shows point totals only.  However, the student grade book shows a percentage.  The bad thing about this aggregation method, though, is that it does not make it possible to ignore empty grades.  An empty grade is counted as a zero.  Therefore, the final grade is not really accurate until the end of the course when all of the grade items have been completed.  It makes it impossible to divide the course up into groups and have different assignments for each group because students who are not required to do an assignment will receive a zero for it.  This is the downfall of this method of grading.
