Planning for accessibility doesn't automatically mean creating multiple versions or discarding activities, assignments, or content up-front because it could be inaccessible for certain students. It means having thought through what you would do if a student for whom that activity was inaccessible registered for your class.
Are you ready to support students needing accommodation for disabilities?
Review the activities and assignments in your online (or to-be-online) course and pick one that may provide challenges to students with visual, hearing, or motor disabilities.
What specific parts of the activity/assignment may be problematic?
How could you potentially revise the activity/assignment to improve accessibility?
What might an alternate version of the activity/assignment look like that would still meet the learning outcomes but eliminate the accessibility issues.
This assignment is not required as part of the badge. It is a thought exercise for personal use.
Can't change a rubric once you've started using it.
