Part one develops the methodology in general terms, and part two illustrates its application by examining the cost vtructure of instructional radio and television projects in developing countries. Part three contains nine case studies in educational radio and television cost analysis: the Nicaraguan Radio Mathematics Project, the Mexican Radioprimaria; the El Salvador Instructional Television System, the Stanford Instructional Television System, the Hagerstown Instructional Television System, the Korean Elementary/Middle School Project, and the Mexican Telesecundaria.
