Noting that teachers of young children can help protect children from getting involved in violence, this booklet provides research and practice-based information on preventing violence in young children's lives. The booklet asserts that young children need to feel safe and loved, need to watch peace-loving people, need to be protected from exposure to violence, and need immediate help from adults if they are victims of violence. Suggestions for early childhood professionals for preventing violence focus on helping children handle anger. The booklet identifies several possible reasons for children's anger, presents ways teachers can model managing their own anger, delineates ways to respond to children's anger, and presents a social problem-solving approach to handling anger. Discipline strategies are also discussed, including ignoring some behaviors, using natural and logical consequences, using timeout, and spanking. The booklet then examines media influences on children's behavior, focusing on children's exposure to television violence. Cautions regarding weapons are presented. Finally, the characteristics of high quality curricula for nonviolence are described. The booklet concludes with a list of print and Web site resources for further information. (KB)
