This book introduces the interdisciplinary field of media education. It presents the dimensions, models, and theories that underlie empirical and applied projects. The development of media education is illustrated historically and in an international comparison. Media socialization, media education, and media didactics are related to one another. Media educational research and its implications for training and pedagogical practice are discussed. The study book offers a compact and easily understandable introduction to media education and includes numerous references to further literature and information sources. Questions at the end of each chapter provide prompts for further engagement with individual topics. For the third edition, the book has been thoroughly revised and updated.
