The rapid pace of technological development often outstrips the ability of legislators and regulators to establish proper guardrails on emerging technologies. A solution is for those who develop, deploy, and use these technologies to develop themselves as moral agents—i.e., as agents capable of steering the course of emerging technologies in a direction that will benefit humanity. However, there is a dearth of literature discussing how to foster moral agency in computer science courses, and little if any research on the effectiveness (...) of such courses in computer science. This paper addresses this gap by providing an overview of an undergraduate course on technology ethics. It then shares and discusses a subset of data collected from a mixed-methods study using a pre-post design that sought to examine the course’s effectiveness in developing students’ moral, intellectual, and civic virtues, as well as related dispositions.
