The instructional materials in this teaching guide for Course II, Unit IV, follow and build upon a previous sequential course described in SO 003 169 offering ninth grade students a study on the development of Western European Civilization. Focus is upon four periods of high development: The High Middle Ages (12th Century), The Renaissance (15th Century), The Age of Absolutism and Enlightenment (17th - 18th Centuries), and The Century of Progress (19th Century). Objectives are for students to gain a sense of human feeling and concern for the men and women of these periods who coped with the universal problems of mankind. Inquiry training is emphasized giving students freedom to inquire into and discuss the whole range of human affairs using a variety of social data to develop increasingly accurate and mature generalizations about the way of life of a given culture in time and place. Expository text reading on the Century in Review, The Major City of the Century, and the Transition (developments between the centuries of high development) with selected primary source readings, statistical data, and audio-visual aids, provide a body of authentic social data on the life of each century.
