This pre- and post-test study examined value system changes resulting from a media ethics course. Over three semesters, 74 students participated in the study. They were given M. Rokeach's lists of terminal and instrumental values on the first day and again on the last day of class and asked to rank each value on the lists in terms of its importance to them. The study was designed to answer several questions about the degree to which formal instruction in ethics could be influential in students changing the relative importance of several values, particularly those deemed important and less important to contemporary, postmodern culture. Results indicated that, for the most part, students were very much in step with postmodern culture. Only small changes were observed in their value systems.
