Upon editing or creating a rubric, instructors have the option to make it weighted.
Switching to weighted makes it so that the scores for each criterion are a specified percentage of the total points possible for the rubric as a whole. If you think about this in overall grade terms, it is similar scoring all of the assignments, exams, discussions in a class out of 100, and then weighting them as 10% discussions, 40% assignments, 50% exams in the final grade calculation.
What this means in the case of the rubric is that the highest rating level for each criterion needs to be calculated out of the total points possible for the overall rubric. For example, if the item that will be graded with this rubric is worth 100 points, then all of the criteria need to be out of 100 points for the highest level rating. That way, the correct number of weighted points will be awarded when rating levels are selected when grading.
Note: Instructors may only edit rubrics that are local to their site, and that have not been associated with an item for grading. Once a rubric is in use, it will appear with a lock icon next to it, indicating that it cannot be edited.
Select Rubrics.
In the target Sakai site, select Rubrics from the Tool Menu.
Select the # icon.
To make a rubric weighted, select the # [pound sign] icon.
Remember, locked rubrics may not be edited.
The Lock icon indicates that a rubric is associated with an activity in the site and it cannot be edited. To edit a locked rubric, either detach/unassociate it from the activity where it is being used, or make a copy of the rubric and edit the copy.
Rubric is ready for weighting.
The weighted rubric will display the % [weighted] icon, as well as Weight fields to enter a percent for each criterion.
Enter criteria weights.
Enter a percent weight for each criterion, and edit the points for each of the rating levels if needed.
Tip: IMPORTANT! Remember that the highest rating level for each criterion should be the same as the total possible points for the item that will be graded with the rubric. In the example above, the rubric is configured to be used with an activity worth 4 points.
Note: The total of percent weights entered for the rubric must equal 100%.
Select Save Weights.
After entering weights for all rubric criteria, select Save Weights.
When grading an item using a weighted rubric, the weighted points are shown in bold and parentheses inside each rating cell.
In the example shown above, the Initial Post criterion is 60%, so the weighted rubric will calculate 60% of 4, which is 1.2 points possible for that criterion. The Peer Engagement criterion is 40%, so the rubric will calculate 40% of 4, which is 0.8 points. Adding up the point values of the highest rating levels for each criterion should yield the total point value of the activity and associated rubric (2 + 2 = 4 points).
Students graded according to this rubric will receive a weighted amount of points for each rating level selected. In the example above, the student earned
