The gradebook keeps a 'Grade history' of all changes made to grades. The Grade history report allows grading staff to view a history of what has happened to grades in their topic. This report is especially helpful if topics have multiple graders and a teacher needs to see if a grade/s from one grader (original grade) was altered by another (revised grade).
This is a useful record/overview for the moderator of topic grades.
In the topic, locate the Administration tab . Under Topic administration, select Grades
Click on the Grade history tab
The Grade history tab allows you to Select user (student), the Grade item (assessment activity) and Grader (student). You can select more than one user, all grade items or just one, and all graders or just one.
If you Submit, scroll below the Submit button to see the grade history for the students you have selected
