This study contributes to the literature via a qualitative meta-analysis that illuminates the role of schools in preventing and countering violent extremism and hate crimes globally. By examining and analyzing recent studies at the intersection of peace education and countering or preventing violent extremism (CVE/PVE), the present study develops themes that provide essential lessons for teachers and other educational leaders looking to prevent and reduce violence, as well as build more peaceful school cultures. These themes include the role of power dynamics in the classroom and beyond, the importance of fostering social and community connections, and fostering in students certain relevant cognitive and affective skills.
