This study develops a pedagogy for the teaching of ethical principles in information systems (IS) classes, and reports on an empirical study that supports the efficacy of the approach. The proposed pedagogy involves having management information systems professors lead questioning and discussion on a list of ethical issues as part of their existing IS courses. The rationale for this pedagogy involves (1) the maturational aspects of ethics, and (2) the importance of repetition, challenge, and practice in developing a personal set (...) of ethics. A study of IS ethics using a pre-post test design found that classes receiving such treatment significantly improved their performance on an IS ethics questionnaire. (shrink)
