By Dr. Becki Cohn-VargasNot In Our School Director In a recent NIOT blog, we shared how student leaders from the Not In Our School anti-bullying campaign at Marshalltown High School in Iowa were the ones who spoke up and averted a school shooting. In this four-part series, we will explore the issues of school violence, show one elementary school's activities to stop school violence and offer a two-part exploration of the restorative justice model, a promising strategy for interrupting and ending cycles of violence. Youth Violence Adults distinguish between brutal teasing, bullying, fighting, and a school shooting, but all these behaviors are part of a continuum of youth violence. Behaviors on this continuum can easily escalate. The Center for Disease Control (CDC) considers youth violence a public health issue. In 2010, 4,828 young people ages 10 to 24 were victims of homicide—an average of 13 each day.
