Designed to be used in combination with standard high school textbooks in U.S. history and government, these lessons on the U.S. Constitution can be used singly or in varying combinations and most can be completed in one or two class meetings. There are five chapters. Chapter I is an introduction for teachers. Chapter II includes lessons about the origins and purposes of the U.S. Constitution. The third chapter contains lessons about principles of governmental organization and power in the Constitution. Chapter IV has lessons that feature formal and informal means of constitutional change. The fifth chapter contains 20 digests of landmark Supreme Court cases. Worksheets containing questions to help students analyze the cases are provided. Students are expected to read and answer questions regarding the lesson selections, which include short readings, case studies, and primary source materials. They also read and discuss books, view films, and clarify their own decisions and analyze the decisions of others by filling in a chart known as the "decision tree." Each lesson contains materials for students and lesson plans and notes for the teacher. Lists of additional print and nonprint materials are also provided. (RM)
