For this page on the website I will refer visitors to some resources I recommend- written by researchers and advocates who know more than I do on this evolving topic.
Elizabeth Englander, founder of the Massachusetts Aggression Reduction Center, has a new (2013) book based on the experiences of youth: Bullying and Cyberbullying: What Every Educator Needs to Know
Susan Limber, Robin Kowalski, and Patricia Agatston have written a research based curriculum and book, You will find their work at http://www.cyberbullyhelp.com/
Sameer Hinduja and Justin Patchin have conducted and published fundamental research in this field. You will find their work at http://www.cyberbullying.us/
Nancy Willard has been a tireless and effective innovator and advocate for law, policy, and helpful interventions in this field. You can find her work at http://csriu.org/ and her new website at http://www.embracingdigitalyouth.org/
And in addition, I recommend one more book: Teen Cyberbullying Investigated: Where Do Your Rights End and Consequences Begin? by Thomas A. Jacobs. Judge Jacobs presents teenagers with real court cases from which they can learn their legal rights and responsibilities.
