Teachers have a significant role to play in developing citizens committed to social justice. They can best fulfill this role by guiding students to examine injustice, seek out multiple perspectives on social problems, and develop concrete strategies for improving their communities and nation. This work is best supported by the development of a socially just and empowering classroom community. Thus, education need to teach not only "about" but also "for" social justice, in their personal relationships with students as well as in society as a whole. This article defines social justice, provides a few examples of the ways teachers across the country teach for and about social justice every day, presents steps in developing lessons for social justice, and discusses strategies for teaching social justice.
