Training directors or managers of 160 major corporations of the "Fortune 500" were surveyed to assess the scope of computer use in the training domain; information was received from 56 of the companies. The study focused on five major areas: training applications, hardware, software, courseware, and number of students involved. An analysis of the data collected indicates that (1) the use of computer-based training (CBT) is becoming more commonplace in business and industry; (2) technical skills and management training are the most common uses; (3) the APPLE II is the most prevalent microcomputer in use; (4) software/courseware is primarily internally developed; (5) simulation is the most common instructional strategy used; (6) many of the efforts involve large numbers of employees; and (7) some companies are adopting a phased approach to the integration of CBT. Examples of microcomputer-based training projects in several corporations are described. Future prospects in microcomputer-based training are also discussed, e.g., the use of videodisc, videotext and videoconferencing services, and embedded training. Seven references are listed. (CHC)
