The computing education research community now has at least 40 years of published research on teaching ethics in higher education. To examine the state of our field, we present a systematic literature review of papers in the Association for Computing Machinery computing education venues that describe teaching ethics in higher-education computing courses. Our review spans all papers published to SIGCSE, ICER, ITiCSE, CompEd, Koli Calling, and TOCE venues through 2022, with 100 papers fulfilling our inclusion criteria. Overall, we found a wide variety in content, teaching strategies, challenges, and recommendations. The majority of the papers did not articulate a conception of “ethics,” and those that did used many different conceptions, from broadly applicable ethical theories to social impact to specific computing application areas (e.g., data privacy and hacking). Instructors used many different pedagogical strategies (e.g., discussions, lectures, assignments) and formats (e.g., stand-alone courses, incorporated within a technical course). Many papers identified measuring student knowledge as a particular challenge, and 59% of papers included mention of assessments or grading. Of the 69% of papers that evaluated their ethics instruction, most used student self-report surveys, course evaluations, and instructor reflections. While many papers included calls for more ethics content in computing, specific recommendations were rarely broadly applicable, preventing a synthesis of guidelines. To continue building on the last 40 years of research and move toward a set of best practices for teaching ethics in computing, our community should delineate our varied conceptions of ethics, examine which teaching strategies are best suited for each, and explore how to measure student learning. 

While the CS education community has successfully incorporated tech-ethics assignments and modules into computing courses, we lack a defined process for instructional design to create these materials from scratch across the curriculum. To enable the development of such a process, we explore two research questions: (1) What specific instructional design challenges emerge when creating ethically-integrated assignments for CS courses? And (2) what strategies might overcome them? We address these questions using Research through Design, a method for critically examining design processes. Applying this method to our own process of creating ethics-integrated CS assignments yielded four key challenges: identifying an ethical context, maintaining a technical focus, eliciting both ethical and technical thinking from students, and making the assignment practical for the classroom. Further, the Research through Design approach revealed process-level insights for addressing these challenges, which can apply across the computing curriculum. This paper also serves as a case study of Research through Design for CS education, highlighting the importance of the instructional design process and the behind-the-scenes challenges and design decisions that go into tech-ethics materials. 

How can we teach AI students to use human concerns to guide their technical decisions? We created an AI assignment with a human context, asking students to find the safest path rather than the shortest path. This integrated assignment evaluated 120 students’ understanding of the limitations and assumptions of standard graph search algorithms, and required students to consider human impacts to propose appropriate modifications. Since the assignment focused on algorithm selection and modification, it provided the instructor with a different perspective on student understanding (compared with questions on algorithm execution). Specifically, many students: tried to solve a bottleneck problem with algorithms designed for accumulation problems, did not distinguish between calculations that could be done during the incremental construction of a path versus ones that required knowledge of the full path, and, when proposing modifications to a standard algorithm, did not present the full technical details necessary to implement their ideas. We created rubrics to analyze students’ responses. Our rubrics cover three dimensions: technical AI knowledge, consideration of human factors, and the integration of technical decisions as they align with the human context. These rubrics demonstrate how students’ skills can vary along each dimension, and also provide a template for scoring integrated assignments for other CS topics. Overall, this work demonstrates how to integrate human concerns with technical content in a way that deepens technical rigor and supports instructor pedagogical content knowledge.
