Section I of this report provides a brief review of various experiments and studies conducted in the United States and abroad on the effectiveness of televised occupational-technical courses. Issues discussed include the packaging of televised instruction; the need for preproduction testing; the limitations of television teaching; teacher and student attitudes toward televised instruction; the effects of animation, dramatic presentation, humor, etc. on instructional television; and the effectiveness of various formats and instructional techniques. Section II describes the efforts of the Dallas Community College District to develop a television curriculum in the occupational-technical area. Pilot lessons were filmed of three specially selected courses: Computer Programming, Criminal Investigation, and Radiographic Positioning. The evaluations of these pilot lessons are presented. Section III presents the 1974-75 evaluation results of the four telecourses that were offered by the Dallas County Community College District. Enrollment averaged about 950 students per telecourse per semester. The majority of these students considered the telecourse to be an academically respectable and useful way to earn college credit.
