The publication contains a brief description of three revised programs for teaching senior history. A major aim is to help students understand themselves in relation to the world. Comparison studies relate past to present and an overall interdisciplinary method strengthens the study of history. The focus is on the principle that the course objectives determine the teaching method used and emphasize the development and application of concepts and skills in studying history. Enrichment of the programs by team teaching is recommended utilizing specialized teacher talents, and a broad framework encompassing the varying abilities of students is suggested. The first program, "The Legacy of the Ancient and Medieval Worlds", and the second program, "The Origins of the Modern World", offer broad-based thematic possibilities for study, suggested historical concepts, and include topic suggestions. The third program, "Canada in North America", provides a basis for examining national problems in an historical context relating to international problems. Canadian and American themes are presented from which students and teachers can select. A unit on Central and South America emphasizing current problems is also described. (SJM)
