You have a student with a display that they (or perhaps you) wish to change, have no fear, you are able to do this from your teacher dashboard.
Changing the display name makes sure that the login name that the student chose is never displayed on anything that other students see. Note that changing a student's display name DOES NOT change the students login name. In the case that a student wishes to change their login name, it is better to erase the account and have the student pick a login name that they will remember and is appropriate.
Step 1 - Click on the Student whose name you would like to change
Step 2 - Click on ‘Edit’
Step 3 - Select the ‘Display name’ and change it to something that gives you the last laugh. Ha! No wait, you should be nice. You are better than that.
Step 4 - Hit ‘Save’ - and you’re done!
