Several of the problems typically associated with efforts to extend higher education opportunities to rural communities--including small class size, lack of qualified instructors, and maintenance of quality standards--are successfully addressed by an audio conference network. Students in remote locations can participate in classes offered through regional centers where class size requirements are already met and trained instructors are available. The addition of computer graphics capabilities to such a network increases the potential for classroom interaction and reduces problems associated with delivery of visual aids and other learning materials to distance learning sites. The Voice-Too modem incorporated in the Optel Telewriter II-PC system transmits voice and data simultaneously on one standard, dial-up telephone line, thus preserving the cost effectiveness of the audio conference method, a key to realizing the goal of providing equal opportunity in education to rural America. The Optel interactive computer graphics system was selected to enhance successful audio conference courses offered in northeastern Washington. The Optel system is relatively inexpensive (particularly as compared with interactive television), requires little training to operate, and is portable. The potential exists for a wide spectrum of uses by many sectors of rural communities. (JHZ)
