Anti-bias education is an optimistic commitment to supporting children who live in a highly diverse and yet still inequitable world. Rather than a formula for a particular curriculum, it is an underpinning perspective and framework that permeates everything in early childhood education--including a teacher's interactions with children, families, and colleagues. Anti-bias education developed from the need to identify and prevent, as much as possible, the harmful emotional and psychological impacts on children from societal prejudice and bias. Its four core goals reflect research about these negative influences: (1) Identity; (2) Diversity; (3) Justice; and (4) Activism. [with Catherine M. Goins.]
