While mobile technologies such as mobile phones, personal digital assistants (PDAs) and digital music players (mp3 players) have permeated popular culture, they have not found widespread acceptance as pedagogical tools in higher education. The purpose of this e-book is to explore the use of mobile devices in learning in higher education, and to provide examples of good pedagogy. We are sure that the rich variety of examples of mobile learning found in this book will provide the reader with the inspiration to teach their own subjects and courses in ways that employ mobile devices in authentic and creative ways. This book is made up of a collection of double blind peer-reviewed chapters written by participants in the project New technologies, new pedagogies: Using mobile technologies to develop new ways of teaching and learning. - Preface.
