If you have existing assignments that can easily be transferred to Canvas (such as written assignments, oral interviews, presentations, tests), consider using Canvas as a “home base” or guide of sorts through the content you set up, whether you are providing links to existing external online resources with a guided pathway through content, or whether you are creating/uploading your own learning materials directly to Canvas. In either case, create a clear set of deadlines for completed work so that students have a solid understanding of how to proceed through your class.
Some assignments and coursework are more difficult to transfer to Canvas without significant alterations (such as live, synchronous class discussions or debates). In the latter case, consider revising or altering those assignments. If not possible, consider using Zoom for small group or whole class synchronous video chat (taking into account student time zones and access to the Internet).
