The field-based masters degree program at Emporia State University was designed to meet the needs of fully employed teachers and supervisors. The curriculum materials and delivery system sought to address the following research-based needs: (1) create an ongoing organizational policy making structure; (2) develop a method of shared decision making at an individualized teacher level; (3) relate the majority of the inservice program to the university graduate credit system; (4) extend preexisting university graduate degree programs into a field-based mode for curriculum development; and (5) engage all participants in an ongoing cyclic process of learning-innovating-implementing-evaluating. Research and development products were adapted and packaged for the inservice instruction as substitutes for the requirements of the regular degree program. Courses focused on needs assessment, developing instructional plans, supervision of instruction, and interpersonal communication. The delivery system was supported by both the university and the local education agency, and a Teacher Corps group helped in bringing about the needed institutional change. (DS)
