Ethical questions have long been the impetus for philosophical inquiry around the world. University teachers must wrestle with the challenging goal of incorporating millennia of ethics research from many cultures into the demanding environment of a college or university classroom. When ethical questions arise in the classroom, during advising or in other academic settings, university and college instructors may appeal to the ethical codes within their own discipline for guidance. The materials that follow briefly review teachingrelated sections of the professional codes of conduct from five disparate fields of scholarship (history, physics, engineering, nursing, and psychology) and seek common themes that can guide university and college instructors in general approaches to ethical dilemmas as well as specific situations. Across fields, ethical teaching reaches beyond classrooms; ethical teachers reinforce these ideas by modeling appropriate behavior, and ethical teachers seek to extend ethical behaviors beyond their students and into society at large. The article closes with appeals for explicit graduate education in ethics and for instructors to recognize the larger ethical context in which they teach.Discipline-specific ethics codes vary widely, and each code seeks to guide those involved in the variety of activities subsumed within the discipline. The disciplines chosen for this article reflect a range of theoretical scholarship, basic science, applied science, and physical and mental health care. Despite this extensive breadth of topical areas, the selected ethics codes share common ground, and each addresses appropriate education and training within a discipline. The materials briefly address differences in the approaches of the chosen ethics codes and then more thoroughly explore similarities, particularly those that translate into tangible classroom behaviors for university and college teachers. 39 4
