An evaluation of the instructional materials used by high school and college students who participated in the Model United Nations Program showed that the program is uncritical of the United Nations (U.N.) and biased against the United States and the West in general. These materials are strongly promoted by many prominent educational professional organizations. Examples of some of the biases found follow. The core curriculum being taught through the materials is the New International Economic Order (NIEO), which teaches that capitalist nations are exploiting poorer nations and that the solution to this exploitation is the massive redistribution of wealth from the developed nations to the Third World. There is no analysis of the internal problems of developing countries. Other curricula support the U.N. continual condemnation of Israel and South Africa, never mentioning PLO terrorist activities, the training of Angola troops by Soviet advisors, or the extensive U.N. funding of Marxist guerilla groups. Other areas of bias were found in the way the materials treated population, food, disarmament, U.N. peacekeeping, and human rights. A balanced program in international affairs is urgently needed. (RM)
