The planning and operation of Jefferson County (Colorado) Public Schools' foreign language camps are described. The weekend-long camps attempt to duplicate an authentic cultural experience in a foreign village through cultural activities and language immersion. French, Spanish, Russian, and German camps are conducted for county high school foreign language students. Activities such as cooking of foreign cuisine, crafts, singing, and shopping are all conducted in the target language. Teachers and native speakers assist in creating the atmosphere and experience. Participation in the camp weekends is voluntary and available at a low cost to each student. Format, planning and budget considerations, goals, and evaluation procedures are summarized. Response to the camps since their 1970 inception has been favorable and has led to increased foreign language enrollments. An evaluation instrument, a planning handout, and the 1982 financial reports for each of the four camp sessions are appended. (RW)
