The current placement of the "Submit" button creates a "slip" in user behavior where habit-clicking "Next" leads to an accidental final submission.
I think Canvas could easily fix this by:
- Moving the Submit button away from the navigation buttons (maybe above the question instead of below it)
- and/or Adding a "Confirm Submission" prompt.
I firmly believe improving this aspect of Canvas' assignment workflow will immediately and significantly impact students who like myself accidentally submitted a midterm without being able to check over my answers.
