Undergraduate software engineering courses typically require students to work on team-based projects that reinforce disciplinary content and soft skills. At the same time, these students, particularly those at liberal arts institutions, are required to take courses that focus on civic issues, including on racial and ethnic inequality. Often, students perceive these courses to be outside their disciplinary areas, and may not comprehend how these topics are applicable to computer science and software engineering. Author 1 teaches Software Engineering while Author 2 teaches Penology at a primarily undergraduate liberal arts institution. Both had been individually pondering approaches to help students in their respective courses more deeply engage in their disciplinary content, and envision how this knowledge can be applied to help address issues related to racial injustice. The murder of George Floyd and the racial reckoning that followed in summer 2020 deepened each one’s commitment to making racial justice a focal point of her class in the fall 2020 semester. Wanting to focus specifically on racial injustice and mass incarceration, and embracing the benefits of interdisciplinary learning, project-based learning, they designed a collaboration between their classes and the local chapter of The Campaign to End the New Jim Crow, a community organization dedicated to ending racial injustice in the criminal justice system. This paper reports on the experience of Authors 1 and 2 as they and their students grappled with issues of racial injustice in the criminal justice system, and drew upon their own disciplinary backgrounds to apply computational thinking and software engineering principles to help the community better understand these issues and advocate for reform. The paper also describes the experience of teaching courses from different disciplines in a collaborative model, working closely with a local community partner to support its work on an identified social issue, and the learning outcomes, as well as the benefits and challenges of this approach. Future directions will also be considered.
