Development of Bilingual Phonological Awareness in Spanish-Speaking English Language Learners: The Roles of Vocabulary, Letter Knowledge, and Prior Phonological Awareness.

Theories concerning the development of phonological awareness place special emphasis on lexical and orthographic knowledge. Given the large degree of variability in preschool classrooms that house Spanish-speaking English language learners (ELL), this study controlled for classroom effects by removing classroom means and covariances based on 158 children from 40 classrooms. Path analyses of the child-level covariance matrices tested the extent to which vocabulary and letter knowledge in each language predicted growth in English and Spanish phonological awareness of 130 preschool-age, Spanish-speaking ELLs. Results supported cross-linguistic effects of prior phonological awareness and Spanish vocabulary in the development of bilingual phonological awareness. Implications for theory, instruction, and research methods are discussed. [ABSTRACT FROM AUTHOR]
