Statistical instruction for graduate service courses in an off-campus environment is typified by three-hour evening classes of full-time employed students, who have high motivations to learn but diverse backgrounds and little time. Although the goals in teaching are no different from those in the usual campus setting, there are differences in projects and computer work, in textbook selection and use, in exams, and in content delivery. The key elements to efficient communication in this off-campus environment are organization and flexibility in incorporating diverse tools and strategies.
