CSC/ECE 517 Fall 2021 - E2158. Grading audit trail

Problem Definition

After an instructor gave a grade to an assignment, there is no way to track who gave the grade. Any instructor can assign/edit a grade freely. There is no way of tracking who did it.

A grading audit trail must be created and the following information needs to be stored:

1. When a grade is assigned by an instructor, there needs to be an indication of who did it and when it was done.

2. Comments previously provided by other instructors must also be preserved.

This information needs to be stored every time an instructor edits a grade/comment and clicks the save button.

Currently, there are two places need to add grading audit trail:

1. Review grade: Log in as instructor -> Manage -> Assignments -> View Review Report

2. Submission grade: Log in as instructor -> Manage -> Assignments -> View submissions

Additionally, the grading audit trail can probably be a pattern of the submission records history on Expertiza. The related page can be reached by logging in as instructor -> Manage -> Assignments -> View Submissions -> History

At the minimum, a grading log entry must include the instructor id, assignment id, student id, grade, comment and timestamp.
