Vocabulary size is a crucial early indicator of language development, for both monolingual and bilingual children. Assessing vocabulary in bilingual children is complex because they learn words in two languages, and there remains significant controversy about how to best measure their vocabulary size, especially in relation to monolinguals. This…

Despite the growing body of technology-assisted vocabulary intervention studies, few have addressed learning outcomes beyond target vocabulary and the interaction between the interventions and English language learners' (ELLs) initially different levels of vocabulary knowledge. The study examined the differential effects of a texting-based…

Purpose: Despite the increasing population of dual language learners (DLLs) in the United States, vocabulary measures for young DLLs have largely relied on instruments developed for monolinguals. The multistudy project reports on the psychometric properties of the English--Spanish Vocabulary Inventory (ESVI), which was designed to capture unique…

Although a "semantic receptive-expressive gap" appears to be a universal feature of early bilingualism, little is known about its development. We sought to determine if the magnitude of the discrepancy between receptive and expressive standard scores changed over time in bilingual children's two languages. In this longitudinal study,…

Writing is a skill that has increased in significance for both researchers and classroom teachers due to changes in recent standards. Currently, many high school English Learners (ELs) are struggling to master this priority skill. A strategy that has been shown to be effective for adolescent writers is Self-Regulated Strategy Development (SRSD).…

This study examined the writing skills of first-grade students who are English Language Learners (ELLs) or Native English Speakers (NESs). We examined the roles of transcription and oral language skills on contextualized spelling, writing fluency, and writing quality outcomes for ELL and NES students. Thirty-four ELLs (Mean age (A) = 78.03 months,…

Few studies have considered academic vocabulary interventions for students who have learning disabilities (LD) and also are English learners (EL). This research explored the effects of the third year of the Creating Habits that Accelerate Academic Language of Students (CHAAOS) vocabulary intervention for eighth-grade students who received English…

This study examined the effects of older siblings' L1/L2 use on the vocabulary and fast mapping skills in preschool-age children who learn Cantonese (L1) as a home language and start to learn English (L2) in preschool settings. Two groups of bilingual children participated in this study: (1) children whose older siblings used mostly L1 at home…

Science students are increasingly challenged to use technical language related to the topics that they are studying, and therefore, science teachers benefit from knowing which tools are effective to support students in learning to use new terms. This study examined the impact of using one such tool--sentences frames--to teach science vocabulary,…

There is a dearth of research describing the small population of students who have significant cognitive disabilities and are also English learners (ELs). This study expands what is known about this population by describing EL students who participated in Dynamic Learning Maps Alternate Assessments in 16 states during the 2016-2017 year. Data…

In this multi-year study, we taught English/Language Arts teachers of students with learning disabilities in middle school to incorporate 15 min of daily vocabulary activities with students in their intact special education English/Language Arts classes. During Year 1, teachers taught 48 words to their sixth grade students, who learned and…

The present study investigated whether the bidirectional cross-lagged paths between teacher--child language interactions and receptive vocabulary would be significantly different between English language learner (ELL) and non-ELL children. The FACES 2009 cohort was used to address the research goals. Cross-lagged analysis was conducted with the…

The increasing diversity in classrooms throughout the U.S. calls for teachers who are culturally competent and have quality professional development in working with dual language learners (DLLs) in order to ensure children from diverse groups are receiving equitable and high-quality education. This study focuses on teacher characteristics that…

This study is a randomized control trial of full- versus half-day prekindergarten (pre-K) in a school district near Denver, Colorado. Four-year-old children were randomly assigned an offer of half-day (4 days/week) or full-day (5 days/week) pre-K that increased class time by 600 hours. The full-day pre-K offer produced substantial, positive…

Reform initiatives around the world are reconceptualising science education by stressing student engagement in science practices. Yet, science practices are language-intensive, requiring students to have strong receptive and productive language proficiencies. It is critical to address these rigorous language demands to ensure equitable learning…
