PEER is an educational research lab looking at education as a tool to prevent extremism, violence, and oppositional behaviour. Founded in 2015 at 捆绑SM社区, PEER aims to study the understanding of the concept of extremism among teachers, principals, students, and parents in multicultural Canadian public schools. The growing violence in the world triggered by religious and right-wing extremism has been a serious concern and carries 鈥渃ommunal, local, national and international implications in addition to threatening personal security.鈥� One way to counter or minimize this global concern is through preventive educational strategies in a country like Canada where students should develop a mutual and thorough understanding of concepts such as diversity and difference (religious, cultural, gender etc.) in all educational subject. The goal of PEER is thus to explore how teachers, school administrators, students, and parents comprehend violent extremism in multicultural Canadian public schools.
