The measurement of bilingual abilities: central challenges

In this handbook chapter I analyse the concept of bilingual abilities. Bilinguals vary widely in what they can do with their languages or in the ways in which they use their languages on a daily basis. This means that there is a great deal of variability in what the term covers. While many researchers subscribe to the holistic view of bilingualism, in the academic literature bilinguals are still often described in negative terms as having a "deficit" in one or another subsystem of their languages. The key aim of this chapter is to identify what makes individuals with bilingual abilities unique speaker-hearers in their own right, avoiding the fractional view of bilingualism, and how these abilities can be measured

First-language skills of bilingual Turkish immigrant children growing up in a Dutch submersion context

The interdependence between the first and second language of bilingual immigrant children has not received sufficient attention in research. Most studies concentrate on mainstream language skills of immigrant pupils. In some studies, the gaps in the language development of immigrant children are documented by comparing mainstream pupils with immigrant children. The competence in the first language receives very little attention. In order to show the role of first language competence in second-language acquisition and lower school achievement, we present the findings of our empirical study by comparing bilingual Turkish immigrant children (n = 30, mean age = 67.27 months) in the Netherlands and monolingual Turkish speakers (n = 30, mean age = 66.97 months) in Turkey. The evidence presented in this paper shows that compared to monolingual Turkish speakers, Turkish immigrant children lag behind in their first language cognitive concepts, lexical, syntactic, and textual skills. Mothers’ education level turns out to be an important factor in explaining the performance differences of immigrant children. This would have an effect on their concept and cognitive development as well as on their second-language acquisition
