"Le Choc de Multinationales" is a microcomputer game for students in an upper-level commercial French couse, to be played by two opponents, one of whom may be another student or the computer itself as a direct business competitor. The game's requirements for language use and knowledge of business and economics theory and principles are moderate, but the game uses basic economics, international trade, and banking vocabulary and concepts. During the game, which revolves around economic competition, students are required to answer multiple-choice questions or respond to questions posed in French. World news events affecting the economics of the game are randomly reported. The game provides practice in applying business strategies, making decisions, and handling the stockholder-manager conflict of interest. It demands high-level cognitive activity, and it engages the student in an interactive situation in which language study is not the primary focus but in which interesting and relevant subject matter is studied using the second language as a means of communication.
