Bilingual preschool children’s second-language vocabulary development: The role of first-language vocabulary skills and second-language talk input

Abstract

Aims:In this study, we aimed to examine whether five-year-old children with varying first-language (L1) vocabulary skills benefitted differentially from second-language (L2) teacher-led group talk and peer-play talk when acquiring L2 vocabulary in preschool contexts.Design:The participants were 26 bilingual children, speaking Turkish (L1) and Norwegian (L2), who participated in a longitudinal study. At age five, they experienced variability in the amount and diversity of the L2 talk they were exposed to in interactions with teachers and peers.Data and analysis:Preschool L2 talk exposure was assessed by calculating the density of word tokens and word types in video-taped teacher-led group talk and in peer-play talk. The children’s vocabulary skills were assessed in L1 at age five and in L2 at ages four, five, six, seven and 10, using translated versions of the Peabody Picture Vocabulary Test-III. To obtain a more reliable estimate of the children’s L2 vocabulary skills we used data from all time points to ...
