Violent crimes, especially those committed with guns, have been increasing at an alarming rate among children and teenagers. This manual is intended to help teach young people in Ohio how to prevent violence and to assist individuals, groups, and organizations in planning and implementing antiviolence conferences, forums, or workshops for children and teenagers. Included in the manual are materials for planning a youth conference or forum. Topics are (1) "Agenda Ideas"; (2) planning a "Timeline"; (3) "Things to Consider," which provides a list of things people can do to enhance the conference experience, supplies that might be needed, and ways to involve people; (4) "Do's and Don'ts of Conducting a Conference," which offers a short list of smart suggestions; (5) "Profiles of Effective Programs Statewide," which offers program resources; (6) "Speakers Resource List"; (7) "Fact Sheets," which includes "25 Things You Can Do to Promote Peaceful Relations" and "Statistically Speaking," which provides a bulleted list of statistical facts; (8) "Evaluation Form," and (9) "Program Profile Form," both of which are to be used to provide feedback to the Ohio Violence Prevention Center.
