This learning package is a three-semester-hour, independent-study course in principles of economics designed for postsecondary, external degree students. Keyed to the commercially published textbook "Economics Today" (San Francisco, CA: Canfield Press, 1975), the package consists of an administrator manual, a student manual, 14 audiotapes, and a student unit study guide. The manuals describe the course and outline the roles and tasks of the tutor/grader and student. The audiotapes contain supplementary readings. The study guide, which serves as the student's instructor telling him what material should be read, when to read it, and how to evaluate his progress, contains specific objectives, diagnostic tests and keys, and supplementary readings for the eight units which comprise the course. Among these units are introduction to economics; assessing the nation's economic performance; introduction to the Keynesian theory of national income determination; and money, the banking system, and interest rates. Students read the objectives of each unit and take a diagnostic pretest. The guide refers them to textbook and supplementary reading assignments for items missed. Students check their mastery of objectives with posttests. Final exams are required. Only the administrator manual and the unit study guide are on microfiche. Hard copies of the learning package, with or without the textbook and including the examinations and audiotapes, are available from the Institute for Personal and Career Development. (Author/RM)
