This guide is designed to provide information on planning assistance and available options to schools that are preparing for the use of technology for curricular improvement. The information presented here is current as of March 1, 1992, and is most relevant to school districts in Alaska, Idaho, Montana, Oregon, and Washington. The first of six technologies discussed is communications satellite television, two-way audio. This section describes organizations that produce complete courses or units of instruction in a variety of subjects and levels for students. The second technology discussed is satellite television providing one-way television programming with no interaction between receiver and sender. This section describes organizations that provide supplementary materials for use by teachers rather than full instruction in courses. The third technology considered is broadcast and cable television, which require only standard television receiving systems in the school, although a telephone line is needed for two-way voice contact for one of the services, and another offers videoconferencing as well as instructional programming. The fourth technology described encompasses computer and telecommunications services, which rely on computers, modems, telecommunications, phone lines, and electronic mail systems to provide complete courses; supplementary instruction; or information via databases, bulletin boards, and networks. Other sources of assistance are then described, including the Education Satellite Network, statewide networks such as those in Montana and Oregon, and private companies. The guide concludes with a listing of subscription publications useful in selecting instructional and inservice opportunities through distance education systems. A brief guide to planning and decision making and a glossary of terms are appended. (DB)
