Since telecourses were first offered in the Dallas County Community College District in the fall of 1972, consistent efforts have been made to evaluate their instructional effectiveness and the degree to which they satisfy the needs of enrolled students. This report presents a summary of the evaluation projects which were conducted during the first three years of the program. Administrative organization of the courses and telecourse design and development procedures are described, followed by summaries of the findings of student surveys for each course. The surveys elicited information on student characteristics, and student assessment of instructional techniques, administrative factors, and use of television as an instructional mode. Appendices include tables comparing enrollments and grade distributions for televised and nontelevised sections of the same courses; the questionnaires used in the various student surveys; the results of a study designed to determine reasons for student withdrawal from a particular telecourse; the results of a study designed to examine the success of English 101 telecourse students in English 102; and a comparison of the characteristics of telecourse students and on-campus students.
