Five award-winning high school and college economics education projects of the Program for Innovative Teaching of Reasoning are summarized. Preceding the summaries, an essay by Marvin Bower of the Joint Council on Economic Education suggests that developing reasoning abilities creates a happier and more effective individual, a more effective voter, and a more effective and satisfied jobholder. The first project contains five lessons in economic reasoning for high school students. Students recognize choices, consider alternatives, develop criteria, apply knowledge, assess probable consequences, and take action based on cost-benefit analyses. The second project suggests experiential projects in population dynamics, agriculture, marketing, housing, and education for college economics students. The third project describes the Managing Independent Living Program for institutionalized adults in transition. The program teaches the process of reasoning to solve problems related to career and life planning, housing, and consumer needs. The fourth summary describes a comprehensive high school program which teaches the basic principles of economics, reinforces these principles with various activities, and requires students to apply economic logic to a variety of subjects and to hypothetical situations. The final summary proposes college economics course assignments, each based on an economic policy issue. (KC)
