We Gotta Work With What We Got: School And Community Factors That Contribute To Educational Resilience Among African American Students, Denae Bradley

Electronic Theses and Dissertations

This thesis examines how Black residents in the Mississippi Delta claim and deploy agency and resiliency in a rural community context entrenched in a legacy of oppression. Black, low-income communities are implicitly labeled non-resilient when macro-level community capitals and resiliency literature are applied. However, I find that resiliency is culturally distinctive and oftentimes detected in ritual, daily processes in Black communities. This thesis rejects dominant narratives that Black communities in Mississippi are only poor, backwards, and lacking. It questions the assumption that dominant institutions have created inescapable boundaries for Black people in this region and challenges the notion that the …
