Hello, Martin, et. al....
I'm also using workshop module for the first time and also having the same difficulty with the module calculating grades substantially lower than the maximum points available. For example, I am using "criterion" grading where students can select the "suggest grade". I have 20 points (or is it percent??? I can not tell from any documentation?) available for a perfect suggested grade. However, if a student selects 20 for another students' perfect grade, they are given a score of 4.0 (which happens to be 20% of 20...).
I therefore am concluding (and am altering scoring criterion's suggested grade) that the suggested grades in criterion scoring must be in percent and not in whole points. It would be nice to know this, i.e., how about "suggested percent correct" or some other label than "suggested grade" or "suggested score."
I'm thinking I'm on the right track here but with all the options and all the grading going on, it is confusing when I am not sure what the unit measure of the grade actually is and which seems to vary depending on which type of grading is employed. Moreover, once students have assessed another student with a faulty measure, e.g., 20% rather than a perfect score of 20, it seems the module will not recalculate the appropriate grade of 20 POINTS when you change the criterion measure to 100% of 20 (to yield a score of 20) when it was first calculated with, e.g., 20% of 20 (yielding a score of 4.0).
Hence you and I are experiencing some of the same issues, I'm sure.
It would be useful to have a unit measure in POINTS and not in percent option.
It would be useful to have an edit function in the gradebook (or recalculation feature in the module) to fix faulty-calculated grades.
It would be useful to have standard unit measures regardless of grading method or documentation relative to unit measure of grades.
I have had to tell students that I'll work this out and get back to them....
Ray is pretty helpful. I'm sure he'll help us both out here as I'm sure there are probably 50 other people or more in the world with the same issue.
Thanks, Ray, for your help and thanks to you, Martin Koops, for posting this question.
