The first half of this report is a description of the funding, the concepts, the programs, and the evolution since 1955 of the Research and Development Center for Teacher Education in Austin, Texas. The second half is concerned with the program of the center which, in 1968, was reorganized to focus on two areas within the framework of individualizing teacher education: (1) the effects of teacher education on teaching behavior including the effect of this behavior on child learning and (2) the development of a teacher education system composed of "instructional modules" which explain, improve, and objectively measure teaching competency. Guidelines for instruction of teachers developed from research include psychologically sequential studies, early and varied involvement in teaching, a personalized and individualized curriculum, adoption of tested innovation only, a multimedia library of resources, systems of interaction analysis, information on behavioral science, and an effective instructional procedure. Also included are construction steps in teaching procedures for the "instructional modules." Future work includes further research on teacher behavior, instructional modules, and new kinds of teacher educators. An 84-item bibliography is included. (SM)
