Participants in an online course are visible when they take actions online that other participants in the course can see. In this paper we discuss the notion of instructor visibility and using visibility effectively. We base this discussion on our experience delivering a graduate degree in information systems by asynchronous learning network (ALN). Students in this program never attend a face-to-face class but interact extensively with instructors and fellow students.
