The rise of service-learning in higher education has been critiqued as little more than community service that encourages students to "do good," but fails to generate original scholarship or social change. In this article, we argue that service-learning gives geographers the opportunity to challenge these critiques, by demonstrating the practical and political implications of collaborative research methodologies, while conveying powerful conceptual understandings of inequality. We begin by interrogating the philosophical overlap between experiential and service-based learning in the educational philosophy of John Dewey. Using this foundational approach, several theoretical and methodological debates in geography are examined, celebrating and drawing lessons from classic and current service-learning programs. We conclude with a discussion and reflection on experiences with implementing similar pedagogical projects.
