The National Education Association (NEA) in conjunction with the National Aeronautics and Space Administration, the National Library of Medicine, The Alaska Broadcasting Commission, and the Pacific PEACESAT Network, conducted four satellite experiments designed to improve professional communication among teachers. These programs were the Satellite Seminar, the NEA-Alaska Hour, NEASAT, and the Pan-Pacific Satellite Pilot Series. The report concluded that: (1) teacher-to-teacher exchange is the program's most important aspect; (2) when the course is offered for credit there is less teacher participation; (3) sufficient time must be allowed to mail materials in advance of the programs; (4) a site coordinator is essential at every location, and (5) prior local coordination should be established with all potential users of a satellite radio station to select an optimum site. The advantages of using satellites as delivery systems for NEA programs were summarized. The appendix contains sample press releases, evaluation forms, and discussion questions. (NR)
