Twelve multi-media adult education projects in nine countries are described in this 250-page book. The projects include England's Open University, Japan's Broadcast Correspondence High School and University of the Air, West Germany's Telecolleg, The Netherland's TELEAC, France's RTS-Promotion and Tele-CNAM, Poland's Politechnika Telewizyjna, and in the U.S., the Chicago TV College. The first section of the book outlines eight steps for building an efficient out-of-school instructional media project. The steps are: formulation of the educational problem, definition of the instructional objectives, definition of alternative media systems, identification of limiting conditions, evaluation of alternative media systems, planning the hardware and software, implementation of the project, and continuing evaluation and modification. Each of the case studies includes data about the background, organization, and current operation of each project. One of the case studies, Japan's Broadcast Correspondence High School, also includes data about costs. (MG)
