I teach a college course that is asynchronous,meaning that the students are not required to log in at a specific time. They are given deadlines to complete specific assigned tasks and assessments. In fact, they often are at different points in the course since they can start the course on just about any Monday. This provides many interesting challenges, as you might imagine. I would LOVE to hear from others that might be facing the same issues and be able to brainstorm together.
