This volume is the seventh in the Advances in Service-Learning Research series, and presents a collection of papers selected from those presented at the Sixth International Service-learning Research, hosted by Portland State University in Portland, Oregon in October 2006. The theme of the conference, which is also the title of this volume, was “From Passion to Objectivity: International and Cross-Disciplinary Perspectives on Service-Learning Research.” This theme was selected to showcase several important topics in contemporary service learning and community engagement research. Of key importance is the way in which the chapters selected for this volume reflect the evolution and maturation of research in the field of service-learning—moving from descriptive narratives of the passion for addressing social problems and inequities that was evident in much of the early research (and is still reflected today) to increasingly sophisticated research that draws on multiple methodologies, presents solid evidence, and offers the basis for replication and further exploration through future research.
