Based on behavior, our faculty can summarily remove a student from class for the day of removal and the next class meeting. The law that allows this was of course written without the online classroom in mind, and my college has struggled with how to handle this in our online classes. The ability to suspend a user from Canvas course access would make it easier for faculty at California's public institutions of higher ed to take our statutory role in supporting a safe learning environment.
Proposed workflow: The user details page that an instructor can access from the People page includes a Suspend User link. When selected, a window will display confirming the action. The user will not be able to access that Canvas course using any login method from any previously authorized tool, such as a mobile device. The user can be reactivated by selecting the Reactivate User link. A window will display confirming the action, as reactivation allows all logins for the user to log in to Canvas and regain access to that Canvas course.
Alignment with work in progress: This is already being proposed for sysadmins (User Suspension Link), so some of the work is already done. All that is needed is to expand its potential (make it a permission option for the Instructor role) and narrow its scope (make it apply only to an individual Course).
