An Experimental Evaluation of the Effectiveness of an Audio-Tutorial Method in Teaching Vocational Agriculture.
McVey, Gary C.
To determine the effectiveness of an audio-tutorial technique in vocational agriculture, six treatment schools and six control schools were randomly selected from 48 Iowa high schools qualifying for participation in the study. While each school was provided the same reference material and teaching outline for the 14-day experimental period, the treatment schools were provided audio-tutorial machines and programs of 20 minutes maximum length with 59 slides or less in the four subject matter areas of instruction. Results showed no significant differences between the audio-tutorial and the control schools in magnitude of change in knowledge for each of the four class level comparisons. Statistical techniques to adjust for differences in mean scores resulted in a significant value for the audio-tutorial technique effectiveness in teaching farm credit. The audio-tutorial technique was as effective as the control technique in teaching animal health, commericial fertilizer, and small gasoline engines. This Ph.D. dissertation was submitted to Iowa State University. (GB)
