Transparency Masters for Agricultural Education. An Experiment in Cooperative Development and Use of Visual Aids by Vocational Agriculture Teachers. Interim Report.

The effects of involving vocational agriculture teachers in the development and experimental use of overhead projection masters were tested in this study. Sixteen teachers attended a workshop and outlined the content for an experimental set of masters. After experimental use of this set at a subsequent workshop, 35 vocational agriculture teachers evaluated the usefulness of the masters, recommended revisions, and suggested additional masters. The final set of experimental masters was made available to the state's teachers for use in their classes during the 1966-67 school year. Returned questionnaires indicated that 83 percent of the teachers used the masters during the school year, an additional 6 percent planned to use the masters as soon as equipment was available, and 89 percent desired access to additional material of this type. It was concluded that cooperative work on instructional materials by teachers stimulates interest in their use of such materials and broadens their concepts of instruction. Recommended uses of the masters, methods for using masters, methods for using masters to make transparencies, a prepared set of transparencies, and the questionnaire sent to the teachers are included in the document.
