The articles in this collection on the relationship of learning, dialog and technology, combine different views of dialogic learning stemming from a multiplicity of discipline backgrounds and research interests including educational design, educational science, epistemology, cognitive linguistics, cultural studies, and mobile learning, to name a few. The authors discuss and explore a variety of topics that range from knowledge building over learning communities to dialogic technologies for knowledge co‐construction. Discussing technology and learning against this broad background is indispensable, as the gap between what learners actually need for successful learning and what current technology offers becomes increasingly wide. This book provides reviews of recent developments in the area of technology supported learning for everyone who is interested in educational technologies, collaborative learning, and dialog.
