Dual language learners are a growing population in early learning and care settings. Young DLLs have the potential to develop proficiency in two languages when provided adequate supports; however, most teachers of young DLLs feel inadequately prepared to support DLLs. Cultivating Oral Language and Literacy Talent in Students (COLLTS) is an…

This study used a within-subjects design to explore two instructional conditions for developing vocabulary in second-grade Spanish-speaking English learners (ELs)--extended instruction and embedded instruction implemented during shared interactive reading. Words assigned to the extended condition were directly taught using a multifaceted approach…

The Common Core State Standards and the Next Generation Science Standards require students to understand and produce academic language that appears in informational text. Vocabulary is a critical domain of academic language, but English language learners (ELLs) come to the English Language Arts classroom with more limited English vocabulary than…

This research examines the processes which native Spanish-speaking learners of English and English-only students engage in when inferring meaning for unknown English words that have Spanish cognates.

The purpose of the current study is to elaborate on the statistical nature of the linguistic interdependence hypothesis (Cummins, 1979). It is argued that reading skills across the languages of bilingual learners are differentially robust to interdependence, falling along a continuum mediated by the commonalities between Spanish and English.…

English language learners (ELLs) who experience slow vocabulary development are less able to comprehend text at grade level than their English-only peers. Such students are likely to perform poorly on assessments in these areas and are at risk of being diagnosed as learning disabled. In this article, we review the research on methods to develop…

For the monolingual population, research has shown that vocabulary knowledge is closely related to reading achievement. However, the role of vocabulary has not been studied as extensively in the bilingual population. It is important to look at vocabulary to better understand reading achievement in the bilingual population in the United States.…

A structural equation model of second language (L2; English) reading comprehension was tested on a sample of 135 Spanish-speaking 4th-grade English-language learners (ELLs). The model included 2 levels: decoding and oral language. English decoding measures included alphabetic knowledge and fluency. English oral language measures included…

This study involves the collaboration of researchers with 24 teachers in a 3-year intervention study aimed at investigating and improving vocabulary knowledge and reading comprehension of fourth and fifth grade students for whom English is a second language. Cross-sectional and longitudinal data were collected on various aspects of vocabulary…
