1. Instructor chooses and Grading Scale for the course
- this is the old 2.1.x notion of a grading scale: Letter Grade, Letter Grade With Plus/Minus, etc.
2. When final grades a calculated, the number which 'is' the grade for the student in mapped to the grading scale (in #1)
3. Each student's grading scheme is looked up in CM, and her mapped value from #2 is converted to an acceptable final grade for that scheme
- an 'acceptable final grade' is one that will not cause the Final Grading Tool to barf for that student, and, presumably, accurately reflect the course work completed.
That means that for each grading scale we use, there are 12 mapping vectors required. We used 3 grading scales last go 'round, that would be 36 mappings ... is it feasible to think that each grading scheme warrants a grading scale as well? In that case, it would be 144 mappings.
