Critical examination of factors affecting interaction on CMC

This study examines how computer-mediated communication (CMC) systems, e-mail, bulletin board, real time discussion and listserv, enhance and inhibit on-line interaction from four theoretical constructs and four different types of interaction. A comprehensive search of the ERIC database was conducted and the relevant studies were referenced for the discussion. Analysis reveals that CMC systems enhance and inhibit on-line interaction. The user's perceptions and the attributes of CMC that enhance interactions must both be examined. The successful use of CMC in the classroom requires the selection of the correct CMC medium and group specific instructional design. CMC does not replace face-to-face communication. CMC provides a more flexible delivery and a greater selection of communication channels for online users. The users are able to optimize their communication, on-line image (face), and on-line impression easier than in face to face encounters that require the simultaneous use of all communication channels. Communication models and distance education theoretical constructs are reviewed.
