One of a series of units designed to acquaint secondary school students with business issues, this packet focuses on the decisions facing American companies doing business in South Africa. Teacher and student materials are provided in separate sections. The teacher's guide presents an overview, objectives, five detailed lesson plans, suggested follow-up activities, answer keys, handouts for a student simulation, a review of relevant media resources, and background readings. The student materials contain six activities to help students understand the political and economic situations in South Africa that make United States trade with that country a complex and controversial issue. A reading, summarizing the history, population, government, homelands of South Africa, as well as South African civil liberties, and the Sullivan codes, is followed by 10 discussion questions. In a culminating activity, students role play stockholders of an American company with a factory in South Africa who must decide if their company should terminate its South African operations because of apartheid. A vocabulary worksheet helps students review the terms used in this unit. (LP)
