An Experimental Evaluation of the Effectiveness of Selected Techniques and Resources on Instruction in Vocational Agriculture.
Kahler, Alan A.
The study was designed to test new instructional techniques in vocational agriculture, determine their effectiveness on student achievement, and compare individual and group instructional techniques. Forty-eight randomly selected Iowa high school vocational agriculture programs with enrollments of 35 students or more, were selected for testing the instructional approaches, using seven pilot programs and one control group. The eight approaches included (1) audio-tutorial, (2) single concept film, (3) prepared lesson plan, (4) field trip, (5) demonstration, (6) video-tape, (7) overhead projected transparency, and (8) traditional. Instructional materials, covering four different units, were designed by the investigators specifically for this study. Posttests indicated that all eight approaches had been effective, thereby suggesting that these techniques be considered by vocational agriculture instructors. (GEB)
