Business terminology should be included in foreign language instruction because of: (1) the need to be able to operate in an international business arena; (2) an increasingly linguistically diverse population; (3) real-world communication needs; and (4) business transactions being part of daily living. Language instruction must be made more relevant to secondary school students, and business-related language functions can provide the reinforcement of language skills needed to move students up the proficiency scale. Introduction of business and economic terminology is best accomplished through units, not specialized courses, at this level. Teachers must become more knowledgeable about this terminology in order to teach it, and inservice training is available in a variety of forms. Techniques used in economics, such as the case study, may be useful in the second language classroom. Instructional materials taking this approach are currently available for direct use or adaptation by the teacher. A 28-item bibliography is included. (MSE)
