This loose-leaf book is a guide to an interdisciplinary course stressing a humanities approach to the study of American civilization. Each of the 90 lessons in the guide lists specific goals, materials, procedures, and alternative or additional suggestions on ways to teach about American civilization in the 1920s, the 1930s, and in the period from 1945 to 1960. Lessons are arranged in groups according to subject matter. Topics of the groups are: culture, history, popular culture (radio, movies, and best sellers), architecture and painting as artifacts, poetry and plays as artifacts, and dancing and music as cultural exemplars. Concluding lessons deal with the term project, student evaluation, and the final test. Six appendixes contain material on such topics as extending the American Humanities course and decade novels as artifacts. An extensive bibliography is also included. (TS)
