Starting from a current overview of the significance of media for adolescents, this textbook practically unfolds the foundations, research perspectives, and action concepts of media education. It provides an overview of the changed conditions of growing up in our increasingly mediatized society and introduces the perspective of media education. Current developments in children's and adolescents' media usage are outlined, addressing both the new opportunities and the associated dangers. After a brief look at the roots of media educational thinking and action, central research perspectives are developed, and action concepts, target groups, and fields of application of media educational practice are presented. The main target group consists of students in bachelor's programs in education, educational science, social work, and media education.
