The ethics and economics of supplemental teaching are discussed by a dean of continuing education. It is suggested that the provision of opportunities to faculty that take them away from their primary responsibilities is a minor aspect of the ethical problem. Continuing education overload compensation is generally low, and there are many people outside the university who seek to teach in the university's continuing education program. However, ethical conflicts for university faculty created by continuing education teaching may become more serious in the future. Three possible alternatives to faculty overload teaching are the expanded use of nonfaculty instructors, increasing the number of full-time continuing education faculty, and increasing the proportion of continuing education teaching by regular faculty as part of their normal teaching load. Nonfaculty instructors are generally people with strong educational qualifications and extensive experience in the field in which they are teaching. Full-time continuing education faculty are specialists not only in their subject fields but also in teaching those subjects to adults. However, a full-time staff is more expensive than a part-time faculty. It is possible that continuing education may come to be regarded as an integral part of campus instructional responsibilities of regular faculty members. (SW)
