How does maternal education influence the linguistic environment supporting bilingual language development in child second language learners of English?

Aims: In monolingual situations, mothers with higher levels of education are more likely to provide their children with enriched linguistic input. However, in bilingual situations, the relationship between maternal education and input is more complex because education may have occurred in one, but not both, of the languages. This study details this complexity by examining the relationship between maternal education and linguistic input in a group of children learning English as a second language (L2). Method: Participants were 89 immigrant/refugee children, living in Canada with diverse first languages (L1s). They completed a story-telling task in their L2 and parent reports provided a measure of L1 development. Parents also answered detailed questionnaires about family demographics and linguistic input within the family. Results: Regression modeling revealed that cumulative exposure to the L2 in school, maternal L2 fluency, relative quantity of L1/L2 use by the mother (input) and by the child (output) all influenced children's L1 and L2 development. Relative quantity of input and maternal L2 fluency were, in turn, influenced by the amount of education mothers had completed and the language in which that education occurred. In instances where mothers were educated primarily in the L1, higher levels of education were associated with relatively more L1 input. For mothers who were educated predominantly in the L2, higher levels of education were associated with relatively more L2 input. Across both groups, mothers with higher levels of education had higher L2 fluency. Conclusion: This study revealed a complex relationship between the amount of education a mother has, the language in which that education occurred and the linguistic input she provides to her children. This complexity highlights that monolingual studies about input and environment may not offer a sufficiently nuanced perspective to account for the greater levels of variability found in bilingual situations. Originality: Previous research has offered valuable insights into the relationship between individual difference factors and bilingual acquisition. This study moves the field forward through the consideration of the interaction between factors in shaping bilingual acquisition.
