This paper proposes that integrated services digital networks (ISDNs) can be used to educate groups of people by means of dialogue featuring an interactive exchange of textual, voice, graphic, and pictorial information. Participants need not meet in the same place at the same time. Instead, they may be remote and dispersed, and they can exchange information asynchronously if necessary. Benefits secured from using this approach include an increased flexibility in the delivery of educational services, reductions in travel and other costs and, importantly, the ability to engage a large number of people with different backgrounds in a knowledge-gaining conversation without the necessity of their coming to campus. The article depicts a model seminar to illustrate the ways in which an ISDN conversation might be conducted
