Two activities are described in this report, both of which focus on the multi-disciplinary approach in the development of a consumer education curriculum for high school students. The first activity, which demonstrated the feasibility of a multi-disciplinary approach using local school personnel and resources and university faculty in curriculum development, is a study which developed a set of tested, validated prototype consumer education materials in five steps (each of which is described): operational definition of consumer education, identification of broad areas of competencies, development of specific performance objectives under each broad area of competency, selection and writing of appropriate instructional materials and teaching strategies, and the construction of objective-referenced tests for the measurement of pupil achievement. The second activity described in this report is phase one (of two phases) of Project PACT (funded by the Michigan Department of Education), which focused on how secondary students were affected by teaching performance and teaching context (classroom learning environment/process and student teacher relationships) when teachers taught towards selected consumer education objectives using processes and materials of their own choice rather than systematically designed instructional materials. It is concluded that the success of a consumer education program lies in the training of high school teachers in implementing such a program using an interdisciplinary approach with input from various disciplines as well as educators, teachers, and students.
