This project included three separate studies undertaken to determine the effectiveness of television instruction as a method of effectively delivering information about solar energy systems to present and future workers in related industries, and as a method of delivery for adult continuing education instruction. All three studies used a series of five half-hour videotapes. A survey of the general public in the Las Cruces area was conducted to determine the number and occupational status of people watching the series on a local public broadcasting station. Surveys of random samples then assessed the prior level of knowledge on solar energy of residents from differing socioeconomic strata and any increase in knowledge after viewing the series. The worker study included apprentices, journeymen sheet metal workers, and materials handlers. These workers were given a pretest, shown the television series, and given a posttest. The relative effectiveness of television and regular instruction were compared in solar energy related vocational classes at two postsecondary institutions, and student attitudes concerning television instruction were assessed. Findings were generally favorable in all three studies, and television is recommended as a means of enabling adults of varying educational and age levels to participate in educational activities. Data, survey questionnaires, and references are included. (MER)
