The use of new communication techniques has become a fixed part of teenagers’ lives and poses new challenges to our society. This development carries a lot of positive aspects, but also several threats. Many cases of cyber bullying have become public recently and it is continuously becoming more evident that there is a need for action. On the one hand there is lack of awareness among students concerning the dangers and the penal consequences lurking in the use of new media. On the other hand teachers often lack the necessary knowledge in this area; especially in the technological use of new media students are often way more capable than their teachers. Communication competencies, conflict management and confident educators are needed. An important factor is the structure within the institution of education. There is often a lack of defined processes for occurrences of cyber bullying, as well as no fixed rules. Many questions surface that concern causes, risk factors and consequences. The main focus of this book, however, is the call to implement prevention measures and intervention programs at German schools in order to prepare and aid teachers through practical suggestions.
