In this book, top scholars in the field of mobile communication discuss the major issues related to the use of mobile phones in today's society, such as the tension between private and public, youth mobile culture, creative appropriations of mobile devices, and mobile methods. Each chapter unfolds as an open dialogue between scholars and graduate students of communication. They contain an introduction by a student, followed by a short lecture and a question and answer section with the students, and a closing statement by a student that responds to the scholar's argument. The book is a valuable resource not only for individuals interested in mobile communication, but also students and teachers willing to use the affordances of mobile media to expand the physical boundaries of classrooms and promote collaborative learning practices.
