Findings are presented from the fourth survey of the educational services provided by public television licensees (in this case, n=168), which covered the period from September 1, 1982, to August 30, 1983. Results for a companion survey on the financing of public television's educational services covering Fiscal Year 1983 are also included, and public broadcasting trends are identified, wherever possible, by comparing findings to those of the 1978-1979 survey. Special sections cover current and planned uses of Instructional Television Fixed Service (ITFS) and financing of educational services, and licensee's descriptions of innovative educational research or evaluation activities. An introduction describes the study's purpose, methodology, and data treatment and analyses. Following a summary of the findings, individual chapters detail results regarding the public television licensees; elementary/secondary (K-12) and postsecondary educational services; future educational services; Fiscal Year 1982 instructional income and expenses; and some comparisons of findings. Appendices contain the survey instrument, a summary of reported public television educational services by licensees, and a description of the study methodology. Thirty-seven tables display survey data. (LMM)
