A computerized delivery system in consumer economics developed at the University of Delaware uses the PLATO system to provide a basis for analyzing consumer behavior in the marketplace. The 16 sequential lessons, part of the Consumer in the Marketplace Series (CMS), demonstrate consumer economic theory in layman's terms and are structured to focus on the cognitive behaviors of knowledge, comprehension, applications, analysis, synthesis, and evaluation, based on Bruner's theory of instruction. The model merges the content of consumer economics and the methodology emphasized in computer education into a "life-adjustment" agenda. The resulting conceptual approach provides a mechanism for serving a varied audience of college students, teachers with consumer education responsibilities, or interested adults without significantly expanding resources, while increasing the economics awareness levels of students and faculties in other disciplines. The CMS is divided into four segments focusing on the analysis of rational behavior in the marketplace and wise decision-making, increasing individual earning power, increasing consumer spending power, and the political and legal framework of society.
