Abstract— Statistics show that many dual language learners (DLLs) growing up in the United States are at risk for poor educational outcomes. As a result, national attention has focused on the promotion of DLLs’ academic abilities, beginning in the preschool years. Despite this interest, our understanding of DLLs’ language and literacy development is limited. The purpose of this article is to discuss the current state of knowledge about the language and literacy development of DLLs during early childhood, and to present a research agenda designed to enhance the field’s understanding of DLLs’ development, which, in turn, can help improve the educational outcomes of children who are learning two languages.

在美国长大的双语学习者的语言和读写能力发展：研究呼吁。

摘要——统计数据表明，许多在美国长大的双语学习者 (DLL) 面临着教育成果不佳的风险。因此，从学龄前开始，全国的注意力都集中在提升 DLL 的学术能力上。尽管有这种兴趣，我们对 DLL 的语言和读写能力发展的理解是有限的。本文的目的是讨论有关幼儿期 DLL 语言和读写能力发展的当前知识状态，并提出旨在增强该领域对 DLL 发展的理解的研究议程，从而有助于提高学习两种语言的儿童的教育成果。
