Hi April,
I am teaching a conceptual physics course with mostly asynchronous delivery, but I have live chat sessions during the week with the students so that they can ask questions, get clarification, etc. I also prepare a few questions or discussion topics in case they don't have much to say!
I have 4 sessions scheduled per week, and each student is required to attend at least one a week. I have them sign up in the LMS and I limit how many can be in each session so I have more managable groups.
So far has been working out… >>>
