Grade retention, the practice of holding a student back in the same grade, has been a controversial topic in the United States for decades. English learners, a growing population in US schools, are consistently identified for grade retention more often than their English-only counterparts. The purpose of this study is to test the impact of grade…

We examine the effects of a read aloud replication intervention designed to improve the vocabulary, comprehension, and expository and narrative language outcomes of first grade students. Thirty-nine first-grade classrooms from 12 schools were randomly assigned to a treatment (n=19) or comparison condition (n=20). Teachers in the treatment…

Purpose: The purpose of this quantitative, causal-comparative study was to determine whether English learners who participated in transitional kindergarten perform equally or better than English learners who did not participate in transitional kindergarten in the areas of oral language, written language, and overall language as measured by the…

The texts students encounter are becoming increasingly complex and multimodal. There remains a need to understand the semiotic resources students draw upon to make meaning with these multimodal texts. This study draws on social semiotics as a frame to explore the ways in which eight first graders with a wide range of literacy proficiency levels…

Background: The educational context in South Africa does not always support the development of bilingualism to enable the cognitive and social advantages of dual language proficiency. The emphasis on English as the language of instruction overlooks bilingual competence. This study attempts to show that by considering conceptual vocabulary,…

The purpose of this study is to determine if there is a difference in the English language acquisition of first grade students in transitional bilingual programs as compared to students in dual language programs during the 2017-2018 academic year. The Assessing Comprehension and Communication in English State-to-State (ACCESS) standardized…

The linguistic interdependence hypothesis (Cummins, 1979, 2000) states that children's second-language (L2) proficiency is, to some extent, a function of their first-language (L1) competence. Previous studies have examined this hypothesis with focus on a unidirectional relation from L1 to L2. In the present study, we examined…

This i3 scale-up study examined the implementation and effectiveness of a 3-year literacy intervention developed by the Children's Literacy Initiative (CLI). The study was a school-level cluster randomized controlled trial conducted in 55 elementary schools from four states. Implementation results showed a high level of fidelity of intervention…

Prior research has shown that EL classification is consequential for students, however, less is known about how EL classification impacts students' outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using nationally-representative data (ECLS-K:2011), we use coarsened exact matching to estimate the effect of EL…

This quasi-experimental study tested the efficacy of a research based biliterate reading strategy, Lotta Lara, that is part of a larger paired literacy instructional program. Its purpose was to investigate whether the biliterate reading strategy, which focuses on reading fluency, comprehension, and oracy through whole group instruction, impacted…

This study investigated the effect of mother tongue instruction and gender on second language acquisition using a causal-comparative quantitative research design. The two distinguishing groups compared were (i) learners that were taught in their mother tongue (Afrikaans) and (ii) learners that were not taught in their mother tongue but in English,…

Research Findings: Previous research has suggested that children from immigrant families face multiple stressors associated with acculturation. One component of acculturation that has not been widely explored in relation to children's socioemotional development is limited English proficiency (LEP). Given that English is the main language used in…

The aim of the current study was to examine the effects of bilingualism on letter and category fluency tasks. Participants were 1,600 monolingual and bilingual children from three cities in Iran: Tehran (Persian monolinguals), Tabriz (Turkish-Persian bilinguals), and Sanandaj (Kurdish-Persian bilinguals). We separately presented nine Persian…

The present study investigated the efficacy of early English immersion in the Shi Da Fu Elementary School in Xi'an, China. Three hundred and fifty one students were tested in Grades 1-6. There were two main purposes that motivated this longitudinal and cross-sectional study. The first goal was to compare the L1 and L2 language and literacy…
