Proctor's work focuses on the intersections between English literacy development and bilingualism among upper elementary school-aged children who speak languages other than English in the home and at school. His theoretical and applied work is carried out in urban settings with attention to cognitive models of English reading comprehension, cross-linguistic transfer, the role of bilingualism and biliteracy in students' schooling achievement, and heritage language maintenance. Findings from these studies inform Dr. Proctor¹s literacy intervention work, which has been carried out with fourth and fifth grade children from English monolingual and Spanish-English bilingual backgrounds.
