I would love to see a "go live" feature in Canvas, similar to Facebook live. Ideally, this video would then be saved to my files (again like Facebook live), where I could share it for students to view later.
When I have an asynchronous online course, it would be really meaningful to be able to schedule a live interactive video session with my students. They would get important updates, and I would be able to check in with them and answer their questions.
I hold office hours on Zoom, but no one seems to come to them. But if they were already on Canvas doing assignments and then were notified that I was live, I think it could help with engagement.
