Crisis intervention materials designed specifically for classroom teachers are still scarce, and their role in crisis prevention and intervention continues to be one for which teachers must take the initiative to educate themselves. With updates in crisis intervention programming and legislation; integration of recent research on school shootings and other forms of school violence; and the addition of such topics as cyberbullying, relational aggression, and the needs of military families, this second edition of Crisis Prevention and Intervention in the Classroom further widens teachers' perspectives on school crises and puts them in a better position to prevent and cope with these events.
