The report is an evaluation of the economic content and teaching strategies in social studies textbooks that are used in grades 10, 11, and 12. The study, conducted by the Center for Economic Education, Purdue University, was part of a kindergarten through grade twelve assessment of the treatment of economics in social studies textual materials made under the direction of the Joint Council on Economic Education. The primary purpose of the project was to provide information that might lead to an improvement in social studies texts. A committee of economists and economic professors selected and analyzed a sampling of textbooks published after 1967 in the following categories: government (including civics), problems of democracy, geography, anthropology, and sociology. High school economics and history textbooks were not examined by this center. Content criteria used were those recommended by the Task Force Report. Major findings indicated that the ability to both identify an economic problem and to analyze economic issues will not be instilled by the materials. Economics was not treated systematically; errors of fact, out-of date information, and misapplication of economic concepts were found. Related documents are SO 006 759, SO 006 760, SO 006 762.
