The potential value of the use of television in teacher training in Iran to help fill the gap between the present work force of teachers and the number needed for full enrollment of the nation's children at the elementary and secondary levels is considered. A computer model which has been developed to permit quick and easy assessment of the impact of alternative educational strategies, including educational television (ETV), is provided for use by Educational Radio and Television of Iran (ERTI) in planning its role in teacher training. The report contains a summary of the major findings and recommendations, description of the background research which led to the development of the analysis, and the analytical model and its result. Appendix A presents a brief overview of how ETV has been successfully used in a range of applications at the elementary, secondary, and post secondary levels outside Iran. Appendix B includes detailed information from a survey on ETV use in such institutions as Chicago TV College, Outreach Consortium, Oregon State University, and British Open University. (VT)
