The Roots curriculum, for student-driven positive school climate. 

Designed for middle schools, grades 5-8. Princeton University, 2013

This curriculum is open access: Free for all interested parties 

Evidence demonstrating the positive effect of this curriculum on students' perceived norms of social conflict and on student behavior is described in the following peer-reviewed publication, based on a 56-school randomized controlled trial run in public middle schools, grades 5-8, in the state of New Jersey in 2012-2013. 

"Despite a surge in policy and research attention to conflict and
bullying among adolescents, there is little evidence to suggest
that current interventions reduce school conflict. Using a large scale
field experiment, we show that it is possible to reduce
conflict with a student-driven intervention. By encouraging a
small set of students to take a public stance against typical
forms of conflict at their school, our intervention reduced
overall levels of conflict by an estimated 30%. Network analyses
reveal that certain kinds of students (called “social referents”)
have an outsized influence over social norms and
behavior at the school. The study demonstrates the power of
peer influence for changing climates of conflict, and suggests
which students to involve in those efforts.
