Students use technology in natural ways that allow them to do what they want: communicate with anyone they want, in the time and space that suits them best. 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.
