RESEARCH TECHNIQUES EMPLOYED TO EVALUATE THE EFFECTIVENESS OF THE PEACE CORPS ETV PROJECT STEMMED FROM TWO MODELS OF FEEDBACK. INFORMATION PROVIDED IN "INDIVIDUAL FEEDBACK" IS OF VALUE AT A PRAGMATIC LEVEL, WHEREAS INFORMATION FROM "PROJECT FEEDBACK" CAN BE USED BY ADMINISTRATORS FOR POLICY DECISIONS. THE MAJOR TOOL FOR PROJECT FEEDBACK, TREATED ALONE IN THIS REPORT, WAS SELF-COMPLETION MAIL-RETURN QUESTIONNAIRES, DISTRIBUTED BY PEACE CORPS VOLUNTEERS WORKING IN THE FIELD AND DESIGNED TO MEASURE COLOMBIAN TEACHERS' ATTITUDES TOWARD THE PROJECT. RESEARCHERS WERE PLEASED WITH THE METHODOLOGICAL SUCCESS OF THE QUESTIONNAIRES, WHICH WERE USED IN SIX PROJECT SURVEYS. QUESTIONNAIRE ITEMS COVERED SATISFACTION WITH THE TELEVISION CURRICULUM, DISSATISFACTION WITH THE CURRICULUM (THROUGH A SPECIALLY DEVELOPED "CHECK-LIST" PROCEDURE), SATISFACTION WITH TELEVISED COURSES FOR TEACHERS, AND EVALUATION OF TEACHER GUIDES FOR PREPARING LESSONS AND MOTIVATING STUDENTS. ADDITIONAL RESEARCH TECHNIQUES TO OBTAIN FEEDBACK WERE SYSTEMATIC TEACHER INTERVIEWS, SCHOOL AND CLASS VISITS, SMALL SCALE TESTING, USE OF AN ETV LABORATORY, AND THE CRITICAL INCIDENT TECHNIQUE. APPENDICES INCLUDE QUESTIONNAIRES IN BOTH SPANISH AND ENGLISH, WITH REFERENCES TO DISCUSSION OF ITEMS IN THE TEXT OF THIS REPORT. (LH)
