Learning is the attainment and application of knowledge or skill. Effective online instruction should integrate interactivity. Online interactivity 1) includes a message loop, 2) occurs from the learner's point of view, 3) provides for content and affective outcomes, and 4) is mutually coherent. These characteristics must be woven into online interactive devices such as discussion boards, PowerPoint slides, email, and chat rooms to insure learning. Interactivity must be consistent with the course objectives. Increased interactivity enhances learning in online courses just as it does on campus.
