These slides compliment the webinar hosted by Lambda Solutions on the Moodle Gradebook, which is available on Vimeo: https://vimeo.com/62837761. These slides include some information on the Moodle Gradebook Aggregation methods, which can help users when setting up their Grading architecture.

4. Moodle Gradebook
 Setting up your Gradebook
 Setting up your activities
 Marking for your Gradebook
 Aggregation of Marks – weighting your grades

5. Aggregation

6. If wanted
Rubric for Class such as..
 Assignments = 20%
 Projects = 30%
 Exams = 50%
Then use…

7. Weighted Mean of Grades
 With this calculation method, the graded items will
be multiplied by the weight you give them and that
total will be divided by the sum of the weights.

8. If wanted
5 Assignments that are each equal in overall mark, even if
have different amounts by grade:
 1st Assignments (out of 10) = 20%
 2nd Assignments (out of 7) = 20%
 3rd Assignments (out of 36) = 20%
 4th Assignments (out of 13) = 20%
 5th Assignments (out of 9) = 20%
Then use…

9. Mean of Grades
 If you use this calculation method, Moodle will first
determine the percentage scores for each grade item.
It will then sum them those scores and divide that
sum by the total number of grade items.

10. If wanted
5 Assignments that are each equal in overall mark, even if
out of different amounts
 1st Assignments (out of 10) = 10 / 75
 2nd Assignments (out of 7) = 7 / 75
 3rd Assignments (out of 36) = 36 / 75
 4th Assignments (out of 13) = 13 / 75
 5th Assignments (out of 9) = 9 / 75
Overall = mark / 75 * 100
Then use…

11. Sum of Grades
 This is the only aggregation method that does not
internally convert scores individual grade items to
percentages. Using our previous example here is how
it would work.

12. Simple Weighted Mean of Grades
 Similar to Sum of Grades, but you manually edit the total.
 Similar to way Weighted Mean of Grades is calculated,
except that each item is weighted based upon the
maximum points possible for that item. Therefore, a 20
point discussion will have a weight of 20 and a 100 point
essay will have a weight of 100.
