Celebration Animation:
One of the easiest ways to tell if your submission has gone through properly, is to enable the Canvas celebration animation in your profile settings. You can find these settings by logging into Canvas, selecting your profile photo, then the settings item. Scrolling down on the subsequent settings page will reveal the “User settings” under the heading, “Feature Options.” Within the “User settings” there is the option to enable and disable celebration animation. Enabling the celebration animation will allow a burst of digital confetti to display upon submission of an assignment.
View Submission:
After you have submitted your work, you will see information in the Sidebar about your submission. For file uploads, the sidebar provides a link to your submission to download if necessary. This should populate immediately, or upon refreshing the page and remain there indefinitely.
Re-Submission:
If you choose, you may resubmit another version of your assignment using the New Attempt button. You will only be able to view the details of your most recent submission in the Sidebar, but your instructor will be able to see all of your submissions.
*When you resubmit an assignment, you can only access and view your most recent submission. However, instructors can view all of your submissions.
Graded Submissions:
Once the instructor has graded your submission, the Grades link in Course Navigation displays a grading indicator.
You can also see details about your assignment and links to additional feedback in your Grades page.
