The impact of DEEP on 14 participating school systems, levels K-12, is discussed in terms of origin of curricular materials, and its influence in prompting new directions, ideas, or programs. Part II includes reports from individual schools. Each school reports on curriculum development process, objectives, summer institute, nature of the project, evaluation, and summary. Part III is a largely subjective summary statement by DEEP reporters on aspects of decentralization and curriculum. Part IV contains the introduction and summary of the EPDA Institute for Advanced Study in Economics' for Wisconsin DEEP personnel. These aspects are evaluated: relations with USOE, relations with school administrations, pre-institute preparation, physical facilities, field trips, participant communication, full time vs. part time staff, visiting faculty, use of new materials, participant activities, and follow-up arrangements. The two primal objectives of the Institute, yielding an understanding of basic concepts and theoretical structure of economics, and demonstrating procedures, methods, and materials, were in large measure achieved.
