This paper present a model of factors influencing the teaching-learning exchange in adult distance education, focusing on five factors that have primary influence on the teaching-learning exchange: the teacher, the student, the content, the environment, and the learning community. Several techniques are proposed to overcome the limitations of distance education, including a course Web site, a threaded discussion forum (HyperNews), Web-based dynamic feedback forms, visualization, and interactive lecture outlines. Examples are provided of how these techniques were applied in a graduate course for the management of research and development. Measurement of asynchronous adult student preferences regarding these techniques is presented. (Contains 18 references.) (MES)
