This report summarizes findings from an investigation of instructional television and radio utilization in Scotland, which was undertaken in three stages: (1) interviews with head teachers and audiovisual technicians or auxiliaries in 100 primary and 100 secondary schools to study the level of broadcast use, organizational and attitudinal factors facilitiating or inhibiting use, teacher awareness of broadcasting resources, and school organization; (2) discussions with over 400 primary and secondary teachers to analyze school curriculum and its subject-by-subject relationship to available broadcast materials, and the integration of materials into teaching; and (3) staff and pupil interviews and observations of teachers in 24 primary and 18 secondary schools concerning broadcast use and attitudes toward broadcasts. Following a brief overview of the project, three main aspects of the findings are emphasized, first for primary and then for secondary schools: factors facilitating the effective use of broadcasting (school personnel role and attitudes, personnel training, and school resources); factors pertaining to the effective use of broadcasts; and pupils response. Conclusions and recommendations complete the paper. (LMM)
