Arguments for the inclusion of computers in the schools and guidelines for the effective use of computers in educational settings introduce this outline of a college course designed to train students and teachers to successfully utilize microcomputers in prekindergarten through third-grade classrooms. The argument is made that, since computers are being touted as a revolution in pedagogy, teachers must become knowledgable about the potential of computer technology. Only when equipped with such knowledge will teachers be able to assess proponents' claims and to lead in appropriately introducing computer technology into educational settings. Specifically, it is asserted that teachers must consider the context in which computer technology is introduced and the various potential uses of computers. In line with this recommendation, the course described, entitled "Teaching with Microcomputers: The Early Years," offers undergraduate and graduate students the opportunity to use the computer as a tutor, a tool, and a tutee. Tutored by the computer, they experience, evaluate, modify, and write instructional/managerial programs across early childhood subject matter domains. Using the computer as a tool, they learn about word processing and information management for themselves and children. Using the computer as tutee, they "teach the computer," learning to program and to teach young children to program in Logo. Finally, teachers are advised that others will take leadership in providing instruction with computers, if they do not. (RH)
