The Course Delivery Decision Model (CDDM; Brinthaupt, Clayton, Draude, & Calahan, 2014) presents a structured way of approaching the decision about what modality to deliver a course. The CDDM-Revised (Angela Harrison) has been adapted to support McMaster course designers and instructors to consider in greater detail the kinds of activities that are best suited for delivery asynchronously/synchronously and virtually/in-person.
