The Maryland Education Microcomputer Network and Marynet are electronic systems that focus on informal resource exchanges for individuals interested in curriculum applications of microcomputers in pre-school through twelfth grade and in teacher education. The network is free to all Maryland citizens involved with the mission of the schools. Others who wish to participate may make arrangements. An international user group participates through long distance services. The open-exchange process is shaped by its participants and their use of the system. The process is coordinated by a "networker" and several regional and topical "networkers." A research component of this effort focuses on systematic study of the network as "teaching" and "curriculum innovation." Network exchange processes are being studied through use of selected models from research on teaching and teacher education. Designs take several tracks; one focuses on the content of communication, and a second track examines the message system through use of a qualitative approach to disclose the characteristics of electronic communications in educational networking. The third track involves a survey of telecommunication activity to schools and colleges. (JMK)
