Plan and, if possible, implement a discussion activity in your course.
If you are using the course template, it comes with a course-wide, Question and Answer discussion board.
How else do you plan to use Canvas Discussions in your course? Will you have graded discussions? How will you plan to integrate face-to-face discussion with online discussion (if you do)? How will you attempt to foster better discussions?
Part one: document how you plan to use Canvas Discussions in your class?
Part two: if possible, or even just as a test, set up a discussion in your class, using the appropriate options (graded or not, etc), and linked in your course or module(s) as appropriate.
