Book excerpt: Just as the previous generation was raised in front of televisions, adolescents at the turn of the 21st century are being raised in an internet-enabled world where blogs, social networking, and instant messaging are competing with face-to-face and telephone communication as the dominant means through which personal interaction takes place. Unfortunately, a small but growing proportion of our youth are being exposed online to interpersonal violence, aggression, and harassment via cyberbullying. The mission of this book is to explore the many critical issues surrounding this new phenomenon. Key features include the following. Comprehensive – The book provides a comprehensive, up-to-date look at the major issues that teachers, school administrators, counsellors, social workers, and parents need to be aware of with respect to cyberbullying identification, prevention, and response. Practical – While the information is informed by research, it is written in an accessible way that all adults will be able to understand and apply. Expertise – Justin W. Patchin and Sameer Hinduja are Co-Directors of the Cyberbullying Research Center (www.cyberbullying.us). Chapter authors represent a carefully selected group of contributors who have demonstrated both topical expertise and an ability to write about the topic in clear, easily accessible language. This book is appropriate for teachers, administrators, parents and others seeking research-based guidance on how to deal with the rising tide of cyberbullying issues. It is also appropriate for a variety of college level courses dealing with school violence and educational administration.
