Perspectives on Second-Language Development: Implications for Bilingual Education

Abstract

This article provides a guide to basic research in second-language acquisition by characterizing distinct perspectives from foreign language teaching, first-language acquisition, psycholinguistics, and sociocultural factors. The research in these areas provides some answers to common questions about second-language acquisition, including those of optimum age, factors that facilitate learning, the consequences of bilingualism, individual differences, and assessment techniques. It is argued that the crucial insights of the sociocultural perspective must be introduced if we are to have adequate assessments of bilingual individuals or evaluation of bilingual programs.
