An on-line interactive audiographic learning system

Abstract

An on-line interactive audiographic learning system is described. The system is able to deliver synchronized narrative and line-graphic learning information to learners at remote locations via regular telephone lines. A quasi-conversational mode of instruction allows learners to control the interaction by using Touch-Tone telephone signals. Individualized instruction is achieved by providing the learner with the possibility of selecting, stopping, reviewing, and skipping instructional materials at his own desire and pace. Instructional information in both audio and graphic forms are stored electronically on regular stereo audio tapes in modular forms. Multiple tape units are used to store the learning data base. A PDP-8/I computer is used to control the process. Instructional modules are redundantly stored to permit access by multiple learners at different learning stations. Learning activities of each user are recorded. The hardware and software of the system is described. The procedures of course generation, editing, processing, and up-dating are described.
