Relations Among the Home Language and Literacy Environment and Children's Language Abilities: A Study of Head Start Dual Language Learners and Their Mothers.

Results: This study explored the relations between Spanish-English dual language learner (DLL) children's home language and literacy experiences and their expressive vocabulary and oral comprehension abilities in Spanish and in English. Data from Spanish-English mothers of 93 preschool-age Head Start children who resided in central Pennsylvania were analyzed. Children completed the Picture Vocabulary and Oral Comprehension subtests of the Batería III Woodcock-Muñoz and the Woodcock-Johnson III Tests of Achievement. Results revealed that the language spoken by mothers and children and the frequency of mother-child reading at home influenced children's Spanish language abilities. In addition, the frequency with which children told a story was positively related to children's performance on English oral language measures. The findings suggest that language and literacy experiences at home have a differential impact on DLLs' language abilities in their 2 languages. Specific components of the home environment that benefit and support DLL children's language abilities are discussed.
