The document outlines several key differences between online and face-to-face teaching. Online learners may be unfamiliar with expectations and procedures, so instructors must clearly spell out instructions. Online learners are also more likely to quit quickly if the course does not meet their needs, so instructors should provide encouragement and interaction from the start. While face-to-face classes have participators who ask questions, online instructors must be prepared to answer more questions individually. Despite these differences, some principles remain the same, like ensuring clear expectations, regular communication, and quality interaction between students.
