Supported by the Learning by Giving Foundation or other philanthropic sources, many college courses are allowing students to give away charitable grants to nonprofit organizations. In this article, the author shares the experience of a Learning by Giving Economics of Altruism class taught at an introductory level. The class is taught using best practices from service-learning, and its course design, curricular content, challenges, and outcomes are discussed. The class provides the unique opportunity to teach microeconomic principles to a diverse population of students while making a positive impact on the community. Data show that student learning and overall experience with the service-learning exceed their initial expectations.
