Designed as an accompaniment to college level microeconomics lectures, (see SO 011 936), the package contains materials for four approaches to the microeconomics course. The course covers topics of economic concepts, issues, and tools; demand; supply; price and output determination in markets; marginal equivalency conditions and economic efficiency; the organization of industries; public goods and externalities; income distribution; international trade; and concepts revisited. Required texts are: "Economics" (Samuelson), "Microeconomics" (Lumsden, Attiyeh, and Bach), and "Study Guide to Accompany Samuelson), (Robinson). The four approaches are conventional, case study, TIPS (Teaching Information Processing System), and cases-TIPS. All courses are based on 25 fifty-minute lectures. The conventional approach uses lectures, texts, workbook, and study guide as teaching methods. The cases course package contains nine case studies on topics such as the effects of pollution, production decisions, and housing, which are used instead of the workbook and study guide. The TIPS package offers surveys relating to each of the lesson units used to provide progress feedback to students and instructors. The Cases-TIPS package combines the use of the case studies and TIPS surveys used above. Materials relevant to all four approaches are provided: an economics and mathematics pretest, student information questionnaire, psychological inventory, continuous and final student evaluation questionnaire, pretest of microeconomics comprehension, midterm, and final examination.
