Designed for secondary school teachers who are at the initial stages of teaching global studies or introducing global concepts into their courses, this paper reviews ways (1) to introduce an awareness of global issues and the interdependence of our planet and (2) to develop related cognitive skills. Techniques and materials relevant to this teaching are presented. The first section describes 25 activities to help students build global perspectives in terms of cultural awareness, awareness of global interdependence, understanding of the overlapping nature of world problems, understanding the reciprocal roles of the world and the United States, and understanding the need to question and evaluate written and oral statements. Section two suggests 30 activities to help incorporate cognitive knowledge into a global perspective. These involve use of computers, local ecological studies, personal food intake records, map study, and statistical tables. Content areas in which these activities can be performed include economics, history, geography, mathematics, science, and foreign countries. This indicates that global studies is interdisciplinary in nature. An annotated bibliography of relevant materials lists 15 books, nine publications, three simulations, and 24 organizations. Addresses are given for all references. (AV)
