Step 1: To anonymously grade a Moodle review, click on the cog icon in the upper right corner of your class page and then click on Turn Editing On.
Step 2: Go to the desired assignment, select the Edit option, and from the dropdown menu, click Edit Settings.
Step 3: Scroll to the bottom of the page. Under the Grade section, enable blind grading by selecting Yes. Note that you may only enable blind grading before assignments have been submitted. Moodle will not allow you to change this setting after the first submission.
Step 4: Click Save and Return to Course.
Step 5: When you return to the grading screen, you will see that student names have been substituted with randomly-generated numbers.
