The development of a Computer Assisted Language Learning for Information Organization and Production in Europe (CALLIOPE) program is discussed. CALLIOPE is a program launched by the European Community that is intended to provide computer-based foreign language instruction for the business and industrial environment. Program goals are two-fold: (1) to investigate specific terminology employed by participating companies; and (2) to include that terminology in a computer-based instructional program that affords efficient teaching of specialized second-language vocabularies. The development of a program providing relevant and made-to-measure courseware materials for one company is described in detail. Crucial to the program's success was a careful investigation of existing language needs in the company, the collection of company authentic data materials, intelligent analysis and coding of the materials for database use, and the formation of instructional strategies and user interfaces to increase the versatility and multifunctionality of the final program.
