For anyone concerned about students' moral development, academic dishonesty presents a pervasive problem but also a promising possibility. The present paper describes the theoretical and empirical underpinnings of process-oriented, four-component model approach to promoting students' "moral functioning" related to academic integrity, and the research project currently underway that is providing Web-based professional development to teachers for using the model in their high school classrooms. In doing so, we hope to develop a scalable approach that offers teachers an opportunity to be the primary agents of change in transforming the problem of academic dishonesty into a possibility for positive youth development.
