Assignments include Quizzes, graded Discussions, and online submissions (i.e. files, images, text, URLs, etc.). Assignments in Canvas can be used to challenge students' understanding and help assess competency by using a variety of media. The Assignments page shows students all of the Assignments that will be expected of them and how many points each is worth.
Assignments can be assigned to everyone in the course or differentiated by section or user.
The Assignments page supports keyboard shortcuts. To view a window with a list of keyboard navigation shortcuts, press the Shift+Question Mark keys simultaneously on your keyboard.
