This collection seeks to define the emerging field of "ubiquitous learning," an educational paradigm made possible in part by the omnipresence of digital media, supporting new modes of knowledge creation, communication, and access. As new media empower practically anyone to produce and disseminate knowledge, learning can now occur at any time and any place. The essays in this volume present key concepts, contextual factors, and current practices in this new field. --From publisher's description.
