ELI has released a new white paper, Collaboration Tools, by Cyprien P. Lomas (The University of British Columbia), Michael Burke (The University of Tennessee), and Carie Lee Page (EDUCAUSE). This paper discusses how easily accessible and user-friendly collaboration tools allow students to explore, share, engage, and connect with people and content in meaningful ways that help them learn. By relying on the familiar ways students use these tools, faculty can enable new forms of communication and engagement in the classroom, permitting extensions and variations of the informal interactions already occurring in classrooms and hallways, and creating new frontiers for collaboration across geographic boundaries.
