When you first receive your course, if you did not elect to send in your rosters, your classes will be populated with generic account names which you will then assign to your students. You have the ability to edit student identification information in the system so that students' real first and last names will be shown in the grade book, etc. To save time, you can also have students change their own information when they login.
From the Participants page, click the pencil icon next to that student's current name (located in the First name/Last name column).
Edit first and last names
When you are finished editing, click the blue save icon. Note: Changing a user's first and last name will not change their username. Usernames cannot be edited. Editing first and last names will only change the way the user's name appears within the site and in your gradebook.
