This booklet describes the relationship of service learning to the social studies and examines public policy issues as a crucial step in the service learning process. Service learning is defined and explained using the ACT (Active Citizenship Today) approach whereby students: (1) define and focus on their community; (2) research community problems, select one, and research it more fully; (3) analyze and evaluate public policies related to the problem; (4) design and implement a service project to address the problem; and (5) reflect upon and evaluate the process. Student handouts are included, as well as a resource list for further information. (EH)
