In a 3-year, federally-funded program, faculty at St. Olaf College (Minnesota) have developed a series of behavioral and natural science courses in which students with at least the fourth semester of foreign language do a portion of the course readings in the second language and meet once a week to discuss them in that language with the regular course instructor and a colleague from the relevant foreign language department. In addition, a limited number of immersion courses were offered. The federal grant provided support for summer course and materials development, course "overload" stipends and released time, released time for faculty language study, and library materials acquisition. By the end of the 1991-92 academic year, eight classes had been given and five repeated. Languages offered include French, German, and Spanish. The report details development and design of the program and evaluation results, and contains extensive supporting materials consisting of a faculty foreign language survey, 29 references, faculty development workshop materials, a sociology course outline, a faculty course evaluation survey, and articles about the program in scholarly journals.
