Critically Reflective Teacher Dialogue In Asynchronous Computer-Mediated CommunicationMark Hawkes, Ph.D.Dakota State UniversityInternational Conference on Advanced Learning Technologies, August 2001
Computer-Mediated Communications The use of computers and computer networks as communication tools by people who are collaborating with each other to achieve a shared goal, which do not require the physical presence or co-location of participants, and which can provide a forum for continuous communication free of time constraints. (Kaye, 1991, p. 5)
Synchronous Communication • Takes place in real time, just as if two people were talking on the telephone • Examples: group decision support systems, virtual hallways, network video conferencing, Internet relay chat, and MUDs (Multiple User Dimensions)
Asynchronous Communications • These communications are sent to an intended receiver but are not delivered until the receiver physically accesses them. • Examples: Internet, e-mail, newsgroups, listservs, electronic bulletin boards
Characteristics of Asynchronous Communications • Interactivity • Time Independence • Place Independence • Multi-participant Capacity • Communication Storage and Retrievability • Text Orientation

Comparison of communication mediums on levels of reflectiveness
Influences on Critical Reflection • Discourse Moderator • OnLine Rules of Etiquette • Conversational Floor • Discourse Focus • Asynchronous Dialogue • Text Orientation • Time
Computer-Mediated Communication • Facilitates teacher reflection • Satisfies knowledge-based professional development needs • promotes teacher collaboration
Suggestions for Implementing CMC Professional Development • Moderator with limited facilitation role. • Assists participants in gaining access to conversational floor • Ensures technical topics do not dominate discourse • Helps maintain discourse focus • Synthesizes contributions and points out how reflective ideas were processes and how individual messages contributed to the reflective discourse
Suggestions (cont.) • Discourse Focus • Immediately applicable to the classroom • For K-6 teachers: age-level focus • For 7-12 teachers: content area focus • Anchored in pedagogy, not technology
Suggestions (cont.) • Participant Composition • Narrow participation--Homogeneous grouping • Convergent tasking activities--curriculum development, study group, study task force • Broad participation--Heterogeneous grouping • Divergent tasking activities--brain storming, anecdotal/experience sharing . . .
Suggestions (cont.) • Access at home • Better/faster access at home • More time at home • Teachers do a good deal of their professional work at home
Suggestions (cont.) • Teacher Skills Training • Screen for presence of appropriate prerequisite skills • Provide training concurrent with reasonable technology access • Provide technical assistance away from the discourse forum either through e-mail or as a separate conference thread • Provide pointers to helpful online documents (FAQs)
Research Needs • A study of threads of discourse rather than chucks/single messages, including the sustainability of reflection, the diversity of contributions, and the utility of CMC participation in improving teacher practice • The effects of conversational pace, purpose, and range of participants on reflection • Task/role analysis
