I think the grade book calculations in Moodle are pretty clear. If I can score max 18 points in my rubric, but I only achieve 9 points.. my grade is 5,0. This makes sense to me.
But it does not make sense to a lot of my teachers, who have totally different ideas.
First of all.... 0 points gives 1,0 grade. That seems to be the rule in education.
Then, they think that 9 points is way to low to be graded as 5.0. So they say: 12 points is 5.5, which also is the 'grade to pass'.
For this system there are special website like this: https://omzettingstabel.faistos.nl/
So in the top left, insert 18 points as max. score. Then... insert 12 points as 'cesuur' (which equals grade to pass). And now this websites calculates the grades for you according to the number of points.
Score = Grade
0 = 1,0
1 = 1,4
2 = 1,8
3 = 2,1
4 = 2,5
5 = 2,9
6 = 3,3
7 = 3,6
8 = 4,0
9 = 4,4
10 = 4,8
11 = 5,1
12 = 5,5
13 = 6,3
14 = 7,0
15 = 7,8
16 = 8,5
17 = 9,3
18 = 10,0
Question is: how do I get a score like this in Moodle? I have no idea.
Bad thing is: teachers make grades using a rubric, Moodle grades them accordingly, teacher tells student that Moodle grades are wrong and types the score in the feedback field.
That's not how I would like to work.
Does anyone know how to make scales like the above in Moodle? Notice that the difference between 17 points and 18 points is 0,7 grade and the difference between 0 points and 1 points is only 0,4 grade.
You are probably thinking like me... WHY???
It happens to be really common, that's why there are special websites for teachers to use grading tables.
