Parent inferential questions and child responses during shared reading predict DLLs' receptive vocabulary development.

The present study investigated whether parent–child interactions during shared reading in a diverse sample of 91 three- to five-year-old dual language learners (DLLs) in Norway supported the development of the children's first (L1) and second language (L2) vocabulary skills. The dyads spoke 11 different L1s (i.e., Arabic, Polish, Somali, and Urdu). The analysis of shared reading was based on predefined story elements in the book, and differentiated between whether central story elements were introduced as parent inferential questions and child responses, or as parent and child narrative statements. The children's L1 and L2 receptive vocabulary skills were assessed prior to the reading as well as 8 months later. Regression analyses revealed that parent inferential questions predicted children's L1 vocabulary development across the time-period. Child responses to adult inferential questions predicted their L1 and L2 vocabulary development. These findings support the growing research base that emphasizes the importance of eliciting child reasoning during shared reading. [ABSTRACT FROM AUTHOR]
