The two major goals of this study were: 1) to explore the comparative effects of service learning and community service on the cognitive and affective development of college undergraduates and 2) to enhance our understanding of how learning is enhanced by service. These questions were explored by means of a quantitative longitudinal study of a national sample of students at diverse colleges and universities and a qualitative study of students and faculty who participated in service learning at a subset of these institutions.
