Although commuter students-those who do not live in institution-owned housing on campus-account for more than 86% of today's college students, their unique needs have neither been adequately understood nor incorporated into policies, programs, and practices. This sourcebook explains how to use what we know about commuter students' lifestyles and concerns to create communities of learners that meet the distinct needs of students who live off-campus. The authors show how curricular learning communities can help students overcome their sense of isolation from faculty and peers. They offer practical techniques to involve commuter students in teamwork and research. And they provide a range of other innovative ways to create communities of learners-from building a sense of community within individual courses to the creative use physical space, information technology, living-learning communities, and experiential education programs. Editor Barbara Jacoby concludes the volume by examining the obstacles to involving commuter students in learning, offering strategies that have proven effective across different institutional settings. This is the 109th issue of the quarterly journal New Directions for Higher Education.
