Many schools offer service learning—community service linked to classroom studies—to help students become more effective participants in a democratic society. Different forms of service learning combine various amounts of discussion and analysis of social issues with engagement in activities that have real impact outside the classroom. What we call “Social Enterprise for Learning,” or SEfL, involves students in both thinking about a civic or public issue and doing something about it. In this paper we describe the process we have developed for organizing SEfLs in high schools and how they evolve together with local educational and community partners. We include brief accounts of several SEfLs in San Francisco, to demonstrate how this process can be successfully replicated.
