The model we are trying to support here uses a rubric and a 5 point scale for both the peer assessment of submitted work (assessment 1- 50% of the grade) and assessment of feedback ( assessment 2- 50% of the grade)
Currently this translates 0-5 into a percent when displaying a final mark.
0 = 0%
1 = 20%
2 = 40%
3 = 60%
4 = 80%
5 = 100%
So in your scenario above, Bob would receive 100% from Alice, Cindy would receive maybe 40% from Alice, and Dan would receive 0. These values would have to be calculated back to form part of the Bob, Cindy, and Dan's assessment 2.
If feels so "almost there" but maybe I'm just an optimist. Thanks for any further thoughts. Really appreciate your assistance.
