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…

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 explored subprocesses of reading for 157 fifth grade Spanish-speaking English language learners (ELLs) by examining whether morphological awareness made a unique contribution to reading comprehension beyond a strong covariate-phonological decoding. The role of word reading and reading vocabulary as mediators of this relationship was…

The current study unites multiple theories (i.e., the orthographic depth hypothesis and linguistic grain size theory, the simple view of reading, and the common underlying proficiency model) to explore differences in how 113 fourth-grade Spanish-speaking English learners (ELs) approached reading in their native language of Spanish, which is…

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. Conducted within the context of a large-scale vocabulary intervention that taught word inferencing strategies, including a cognate strategy, this…

This three-year longitudinal study investigated the role of language of instruction in moderating the relationships between initial levels of English oral language proficiency and Spanish reading comprehension and growth in English reading comprehension. The study followed Spanish-speaking English language learners in English-only literacy…

This study describes the development and validation of the Extract the Base test (ETB), which assesses derivational morphological awareness. Scores on this test were validated for 580 monolingual students and 373 Spanish-speaking English language learners (ELLs) in third through fifth grade. As part of the validation of the internal structure,…

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.…

This paper describes the development and validation of the Cognate Awareness Test (CAT), which measures cognate awareness in Spanish-speaking English Language Learners (ELLs) in fourth and fifth grade. An investigation of differential performance on the two subtests of the CAT (cognates and noncognates) provides evidence that the instrument is…

The relation of language of instruction and vocabulary to the English spelling of bilingual first graders receiving either English or Spanish literacy instruction and of monolinguals in English literacy instruction was explored. Only bilingual students in Spanish literacy instruction (SLI) exhibited Spanish-influenced spelling, indicating a…

This study compares 2 measures of reading comprehension: (a) the Woodcock-Johnson Passage Comprehension test, a standard in reading research, and (b) the Diagnostic Assessment of Reading Comprehension (DARC), an innovative measure. Data from 192 Grade 3 Spanish-speaking English language learners (ELLs) were used to fit a series of latent variable…

This study explores influences on bilingual children's phonological awareness (PA) performance in English, examining the role of language of instruction and vocabulary. English monolingual and Spanish-English bilingual kindergartners and first graders receiving either English or Spanish literacy instruction were assessed in English PA and in…

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.…

This study explored a holistic model of English reading comprehension among a sample of 135 Spanish-English bilingual Latina and Latino 4th-grade students This model took into account Spanish language reading skills and language of initial literacy instruction. Controlling for language of instruction, English decoding skill, and English oral…
