In this article, I describe the evolution of a problem-based service learning project in an undergraduate Abnormal Psychology course. Students worked in teams on a semester-long project to locate and evaluate information and treatment for specific psychiatric disorders. As part of the project, each team selected relevant bibliographic materials, made site visits to area treatment facilities, and prepared resource materials for people in the community seeking information on psychiatric disorders. I modified the process but not the content of the project over 4 semesters. Student evaluations improved significantly after I implemented students' suggested changes.
