This chapter provides a broad overview of the findings of research on bilingualism and second-language learning and analyzes how theories in these areas have been reflected in thinking about the education of language-minority children in the United States. The literatures associated with these traditions are diverse in their methodologies and epistemologies and have undergone dynamic changes over the course of their history, extending back well over a century. They have developed largely independently from the educational and programmatic concerns that are the focus of this study, but they provide the fundamental science for the linguistic aspects of our inquiry. By necessity, a broad overview of these rich traditions involves a high level of synthesis.
Bilingualism and Second Language Acquisition
The goal of this study was to understand how language exposure influences the receptive vocabulary development of simultaneous bilingual children. To this end, we targeted nine German—French children growing up in bilingual families. Their exposure to each language within and outside the home was measured, as were their receptive vocabulary abilities in German and French. The results indicate that children are receiving imbalanced exposure to each language. This imbalance is leading to a slowed development of the receptive vocabulary in the minority language, while the majority language is keeping pace with monolingual peers.
Second-language acquisition SLA , second-language learning , or L2 language 2 acquisition , is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. The field of second-language acquisition is a subdiscipline of applied linguistics , but also receives research attention from a variety of other disciplines, such as psychology and education. A central theme in SLA research is that of interlanguage , the idea that the language that learners use is not simply the result of differences between the languages that they already know and the language that they are learning, but that it is a complete language system in its own right, with its own systematic rules. This interlanguage gradually develops as learners are exposed to the targeted language.
