A report on the 1985 Higher Education Utilization Study provides estimates of the availability, use, and support of instructional telecommunications technologies (video, audio, and computers) in U.S. colleges and universities. Use patterns of these technologies in postsecondary teacher preparation programs are also reported. A census survey was conducted with 2,830 public and private two-year and four-year postsecondary institutions included in the Higher Education Directory. Availability of video and audio for instruction concentrated on whether there were various central reception/distribution facilities. Institutional support for instructional technologies was demonstrated in several ways, including consortia membership or services, faculty training programs and expert assistance provided by institutions, and financial support or incentives for use. During 1984-1985, video, audio, and computer technologies were available in some form for instructional use by faculty and students in more than 90% of the institutions. Availability of most forms of equipment, particularly of larger or more sophisticated and expensive equipment, was substantially greater among public than private institutions. Appendices include the questionnaires, information on study design and procedures, a list of members of the Study Advisory Committee, and 126 data tables. (SW)
