A college language instructor recounts his experience in a retraining program in business German at the West Germany's Goethe Institute. Twenty-eight individuals from the United States and from five European countries participated in a program that offered (1) a 14-day immersion into business-related German, (2) establishment of German business contacts, (3) discussions with European instructors of business German, (4) materials collection for courses to be offered at home, and (5) research on one topic of particular interest. Research was done in small groups. Visits to industrial and government firms, and seminar excursions in small and large groups were also included. The professional and personal rewards of participation were found to be substantial. (MSE)
