How do I add media to my assignment submission?
You can add media to your assignment, either as part of a text entry, or as your entire submission.
Any attachments added as part of a graded assignment submission are uploaded into your user files but are not counted against your user quota. However, once the file has been uploaded as a submission, you cannot delete the file.
Note: Your instructor will decide what type of submissions are allowed. One or both of these options may not be available.
Click the name of the assignment.
Record/Upload Media via Text Entry
To embed media as part of a text entry assignment, click the Text Entry tab.
Select Media File
Record/Upload Media via Media Tab
If you can submit media as the entire assignment, click the Media  tab to upload or record media. Click the Record / Upload Media  button.
