I want to grade on a 4.0 scale. So I have figured out the percentages (75% & up is A, etc.) That's not hard.
Here's the hard part.
I want to grade some work on a C scale and some on a B scale.
I.e., if it's a discussion, for me, there's really no A or B: you did it on time and wrote enough or not. It's C or below.
On other scales, you can earn a B, but there's no A: let's say spelling. What does it mean to have 'excellent' spelling? You either spell everything right, which is merely good or acceptable, or you have errors.
In effect, I would like some work to get students to C, other work to get them to B, and only some assignments to bring them to A.
I can make Outcomes scales with 2 or 3 points.
But then when points are added to rubrics and then calculated, everything becomes a percentage again: 2 out of 2 becomes 100%, not 50%.
Can anyone think of a workaround?
All assignments considered pass/no-pass could be put in an assignment grouping with a lower weight. But then there's no mixing scales of different values (2, 3, or 4-point scales).
