Abstract: One of the challenges of asynchronous online discussions is soliciting student responses that involve critical thinking. Too often students answer one another with “I agree” or “That’s what I think” and the discussion dead ends. By providing students with models of good questioning techniques instructors will see the class discussion take on new depth. This article provides online course facilitators with an approach to questioning that can deepen student interactions in asynchronous discussions.
