The important role of the teacher in developing morally sensitive individuals is widely acknowledged. This paper examines the integration of context-specific moral development interventions within a four-year undergraduate teacher education programme in Ireland. The intervention strategy employed a case-based pedagogical approach where participants (n = 123) explored and discussed classroom scenarios to prepare them for a six-week school-based placement. Using the Defining Issues Test, results indicate statistically significant increases in levels of moral reasoning post intervention, suggesting that the use of a layered case-based pedagogical strategy provides students with alternative perspectives on their classroom practices and challenges their lay theories.
