Developing Telecommunication Linkages for Microcomputer-Aided Instruction. TDC Research Report No. 1.
Blinn, Charles R.; And Others
A project undertaken at the University of Minnesota evaluated two microcomputer teletraining systems (audiographic conferencing) to determine the effectiveness of this technology for point-to-point and multipoint distance education. System design requirements included broadcast keystrokes, error checking, master-slave linkages, simultaneous voice and data transfer over one telephone line, simultaneous file transfer, and feedback utility. Four pilot tests were conducted with systems by two vendors (Tori and Optel). System components at each location included a modem, a standard telephone line, a device for amplifying voices, and appropriate software. A commercial teleconferencing bridge was used to facilitate linking the instructor with two or more locations. Results indicated that microcomputer teletraining can greatly reduce costs without sacrificing effectiveness. To pay back the initial investment, this technology is recommended where long-term training requirements are conducted on a frequent basis to multiple remote sites. Recommendations for using the technology and for further research are listed. Tables provide background data on the pilot tests and cost comparisons of teletraining and instructor travel. Twelve references are listed. (Author/MES)
