Adjusting student scores with calculationsWays instructors can adjust student scores including scaling.
Verify the formulas before using them and make sure that you are getting the results you expect.
Note: the formulas will work directly on grade items without adding a category, but they will not work for activities such as quizzes or assignments. Categories must be added to get the Calculation function for quizzes or assignments.
Step 1: Go to the gradebook and click Settings
Step 2. Add a category and place a quiz or assignment in that category by itself.
Step 3. Click on the Calculation icon for the category created above
Step 4. Enter one of the formulas with the correct Scale factor (F2) and ID Number. Click save and view Grader report. Hide the actual quiz and display only the category score, which is the adjusted score. See attached example.
* Add the same number of points to each student's activity grade in a category=sum(researchp1,5)
This example adds 5 points to every students score.
* Use a Multiplier=(researchp1*5)
This example multiplies the original points the students earned by same number in this case times five (5).
*Apply Grading Scale
This grading scale scheme is from the following resource http://www.trottermath.net/personal/gradscal.html
From the resource the formula for the Adjusted score
= 100-(F2*100 +F2*OriginalScore)
See the online resource for the scale factor (F1 and F2).
Moodle version of the formula
Simplified formula for above ilearn version example is
Formula by itself
=sum(100, sum((-F2*100),(F2*ID Number)))
- Add extra credit
- Add grade item set it to = the quiz grades eg. =quiz1
- Hide and exclude all students from the original quiz so that grade item is the only grade that is aggregated.
- Lower the number an assignment is worth
