Black Lives Still Matter: Freedom Schools As An Embodiment Of Critical Literacy Through Reflection And Action, Elena M. Venegas, Lakia M. Scott

Bilingual and Literacy Studies Faculty Publications

The continuation of racial inequities in the United States has ignited the recent Black Lives Matter Movement, a protest of police brutality and gun violence. Black lives matter in public school classrooms, too—where students of color face barriers to equitable educational experiences. The Children's Defense Fund Freedom School program is a major component in developing critical literacy skills through critique, inquiry, and transformation through social justice and action. Critical literacy is enacted through identity—mainly as difference, self, consciousness, narrative, and positionality. Historical and contemporary relevance of Freedom Schools connects to the urgency of the Black Lives Matter Movement.
