Computer conferencing (CC) is rapidly becoming a viable and useful adjunct to many distance education delivery systems. This paper deals with the general questions of what might constitute exemplary practice in using CC for teaching and learning, as well as features to look for when selecting a CC system. The "Do's" include: test the technology thoroughly; provide high quality instructional materials and documentation; provide high quality technical support; build CC skills gradually; provide study guides; make CC integral and relevant; plan for information management; plan for group development; keep discussions focused; specify expectations; use a variety of pedagogical techniques; and create discussion summaries. In a CC environment, there are also practices to avoid. These"don'ts" include: using computer mediated communication as an add-on; monopolizing and/or sermonizing; allowing any individuals to dominate; permitting inappropriate exchanges; including "fluff" in the course; and underestimating the work involved.
