Dear All,
I have a course with two assessed components, both marked using a scale with twelve points. If my understanding is correct, this means the following boundaries if you mark in points and want the conversion (tested it with a TurnItIn assignment and seems to be working fine):
| 1 |
0 | 0-8 |
| 2 |
9.090909 | 9-16 |
| 3 |
18.18182 | 17-25 |
| 4 | 27.27273 | 26-33 |
| 5 |
36.36364 | 34-41 |
| 6 |
45.45455 | 42-50 |
| 7 |
54.54545 | 51-58 |
| 8 |
63.63636 | 59-66 |
| 9 |
72.72727 | 67-75 |
| 10 |
81.81818 | 76-83 |
| 11 |
90.90909 | 84-91 |
| 12 |
100 | 92-100 |
(scale points are on the left, the marks carried forward if you have weighted means of grades as a calculation in the middle, and the mark ranges that will give you this scale point in the right).
Now, I want the course total to be displayed in a scale with four points; again, from testing and understanding the following mappings hold:
| 1 |
0 | 0-25 |
| 2 |
33.3 | 26-50 |
| 3 |
66.67 | 51-75 |
| 4 |
100 | 76-100 |
(scale points, point carried forward in calculations and marks range).
What I am trying to understand is how the final mark will be calculated if, let's say, I assign 0.5 weight to both initial assignments marked on the twelve-point scale and then set the display type for course total to real and have the four-point scale selected.
My assumption is:
i) Moodle looks at the mark of assignment 1 on the twelve-point scale and the points carried forward (if that is nine, then the points carried forward is 72.73 and the weight is 50% so it will contribute about 36% for the final mark, which is a two);
ii) If the same is the case for the second assignment, this will give us another two on the four-point scale;
iii) So, we are aggregating two twos with a weight of 50% for each of them and this gives us a two.
Am I right, partially right or completely wrong? Please help as I am completely lost in how the calculations work.
Regards,
George
