Presentations from an International Seminar for Teachers organized at Rungstedgaard in October 1971 are included in this report. The study conference presented seven approaches to the teaching of world affairs: (1) the nation-state which is still dominant on the world scene; (2) the strategy and power-politics relationship between states; (3) the systems theory, in which an integrated complex of interdependent parts--such as the world transportation network--is studied as an interacting whole; (4) peace research and conflict resolution--the causes of war, the conditions of peace, and the changing of attitudes; (5) the role of technology; (6) the concept of collective security--something more than a classical alliance, yet less than a global supranational government; and (7) the relationship between values and foreign policy. Summary discussions following each presentation include the diverse opinions of the Rungstedgaard group as to the proper approach for teaching about conflict and security. Appendixes provide a list of participants, materials for the teachers, and some addresses for teaching aids and information. (Author/DE)
