This paper attempts to describe the advantages of "narrow-band" applications of communications satellites for education. It begins by discussing the general controversy surrounding the use of satellites in education, by placing the concern within the larger context of the general debate over the uses of new technologies in education, and by challenging educators to harness the enormous power of satellite communications for both formal and non-formal educational goals and objectives. It proceeds to analyze the differences between narrow-band and broad-band technologies, and raises questions concerning the educational value for using broadcast television in the classroom, whether delivered via satellite or through terrestrial means. The development of "Open Learning" and non-traditional study programs is cited and discussed, along with the explosive growth of Citizens' Band radio, as examples of ways inexpensive and narrow-band technology can serve changing educational needs and requirements. A variety of narrow-band applications are then offered: Telephony, radio, slow-scan television, data and hard-copy, telex and facsimile, cable radio. A systems view is presented, as are some cost considerations. The paper concludes with the strong recommendation that educators assume a lead role in de-mystifying satellite technology. (Author)
