Teacher Education for Arizona Mathematics and Science (TEAMS) is a technology-based program for preparing scientists and mathematicians for a career in middle school teaching. The metaphor of "reflective practitioner" guided the design and delivery of this program. Students did not respond well to journal keeping and many failed to comply with the requirement. Because of opposition to journaling, the requirement was modified. At the same time, faculty, staff, and students enrolled in a listserv called "Edteams." The listserv has generated an increasing volume of correspondence on a wide variety of topics, some relevant to the program and others not. Some students have recognized the interaction as a type of journaling. Listserv dialog has characteristics that are very different from typical classroom language. The roles of teachers and students are reversed, with students initiating conversations, teachers answering questions, and students reacting. Long and complex conversations develop on listservs, as students explore their developing understandings of both content and pedagogy. Most important, students find that listservs are fun, and they participate in them with enthusiasm. Contains nine references. (Author/ND)
