This paper describes utilizing wiki technology, small group workshops, and reflective writing assignments to "flip" a community engagement/service-learning course for college undergraduates who are tutoring culturally and linguistically diverse students in K-12 schools. Flipped classrooms are gaining popularity in the teaching of science, accounting, and other traditionally lecture-based college courses. In this flipped structure, in-class faculty lectures and presentations are replaced by assignments in a wikispace featuring multimodal resources that students hear, view or read and write about weekly. During class, students rotate through a series of three learning workshops facilitated by faculty and student leaders.
