An Educator's Guide for Changing the World Methods, Models and Materials for Anti-Oppression and Social Justice Workshops
This is a Verified resource
The Centre for Social Justice website provides teachers with a guide that provides activities so students can engage in social justice themed learning experiences. The content is designed within a principles-based education model. Topics include critical engagements with ideas of oppression and privilege, social transformation models, building awareness of difference, and building empathy. The teacher’s guide is available for download as a PDF. Background information and student materials are included.
