If you are used to adding standard Moodle assignment activities, you’re probably wondering how you edit start and due dates for TurnItIn assignments. This is accomplished a bit differently.
Once your TurnItIn assignment is created, click the assignment link from the course page. You will see the assignment details, including the start/due/post dates. To adjust these, click the pencil/paper icon that sits to the far right of the dates.
Note: the “Post Date” is when students are able to access and view their corrected assignment. If desired, this date can be adjusted beyond the due date to give you time to correct.
