With the advent of growing population of culturally and linguistically diverse children, the purpose of this study is to investigate literacy practices and identity construction of biracial multicultural children who enroll in an authorized multicultural school. I selected three biracial elementary children: an American Korean girl, a Vietnamese Korean boy, and a Jordanian Korean boy. Observations and interviews were conducted, and writing samples were collected. Based on the collected data, this study depended on thematic analysis throughout coding and comparative analysis. To capture the power dynamics and social relations, this qualitative study employs sociocultural perspectives and represents three participants’ literacy practices. Findings show that the American Korean student received sufficient feedback from teachers while multicultural children of minoritized languages did not have teachers’ help for biliteracy. Using the social theories of subjectivity, linguistic capital, and addressivity, I discussed how linguistic capital affects literacy learning in different positions and how literacy practices construct their identities in different time and space. Lastly, I propose the importance of the diversity model in multicultural education. (University of Florida)
