Recognizing the demand for teaching concepts in teacher education programs, the Bureau of Educational Personnel Development in 1970 initiated an effort to train educational personnel to develop and use protocol materials--instructional materials, usually employing audio tape, video tape, or film, intended to illuminate a concept by showing instances to which the concept correctly applies. These instances typically involve the behaviors of children and adults as they appear in the classroom or in other community settings in which teachers might be expected to interpret behavior for purposes of education. Description is given of this protocol materials effort which is essentially a training program for project directors. The materials being produced, primarily films, cover the following subject matter areas: educational psychology, reading, literature, language acquisition, Black English, social psychology, teaching analysis, and social studies. Appendices list the eleven pilot projects which were funded initially and described a progressive evaluation system, developed by Richard L. Turner, which currently is used in training project directors as they develop protocol materials. (Author/SHM)
