We evaluated the long-term effects of a supplemental, small-group kindergarten vocabulary intervention in fall and spring of first grade and winter of second grade. Participants included students from two studies, an initial efficacy study and a subsequent replication study, identified as at risk for language and learning difficulties, who were…

This study aimed to examine language at the teacher/classroom level among second-grade classrooms that differ in socioeconomic backgrounds. Measures of teachers' vocabulary input across the school day throughout the school year were examined. There was a significant difference in the proportion of academic word use between classes that differed in…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results. This study investigated the effects of exposure and age of onset of acquisition (AOA) of L3-English, as well as first and second language (L1/L2) skills and use, in the development of…

Learning academic vocabulary is a crucial task for all students, but especially challenging for students with speech, language, and communication needs (SLCN) and those who are multilingual. Following a participatory research strategy, we analyze whether iconic gestures can be integrated in teaching routines in an inclusive elementary school and…

This study examines the intricate relationships between home language use, oral language skills (phonological awareness, morphological awareness, and receptive vocabulary), and literacy skills (word reading and spelling) in English and Chinese among young bilinguals. The sample includes 249 first-grade and 263 third-grade bilingual students in…

How the construct of vocabulary is defined remains unclear although multiple theories have been put forth. In light of the lack of empirical work investigating the dimensionality of vocabulary knowledge in Chinese, the present study investigated the factor structure of Chinese print vocabulary in a sample of 111 Taiwanese children in Grades 1 and…

Vocabulary acquisition is a fundamental element of mastering the English language, necessitating a comprehensive lexicon that evolves through experiential learning to facilitate accurate comprehension and production of language. The current study examined the impact of Total Physical Response (TPR) tasks on the vocabulary acquisition of Thai…

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,…

Purpose: Elementary-age dual language learners (DLLs) from Spanish-speaking homes in the United States are often characterized as at risk for low vocabulary in both Spanish and English. This longitudinal study examined conceptually scored receptive and expressive vocabulary development among DLLs from Spanish-speaking, low-income homes and…

The present study examined the reading comprehension and receptive vocabulary skills of children with poor reading comprehension despite adequate decoding using a regression-based matching technique. Participants included five cohorts of children who were identified as typical readers (N = 70,493 - 75,553) or as children with specific reading…

Purpose: We investigated four theoretically based latent variable models of word learning in young school-age children. Method: One hundred sixty-seven English-speaking second graders with typical development from three U.S. states participated. They completed five different tasks designed to assess children's creation, storage, retrieval, and…

The purpose of this study was to examine how classroom language contexts characterized by peer language skills and proportions of dual language learners (DLL) influenced English language development for DLL and non-DLL children. Participants were 2,131 children from 135 classrooms across preschool through Grade 3. Children were classified into…

This study investigated contributors of English reading comprehension outcomes among predominantly U.S.-born 1st- and 3rd-grade (N = 73) dual language learners (DLLs) from Spanish-speaking, low-income homes who attend English-only instructional schools in the Southern region of the United States, which is experiencing historic rates of school-age…

This study aimed to investigate if a universal 24-week oral language and emergent literacy programme delivered to students in the first year of schooling positively impacts reading performance 2 years post intervention. Eighty-nine participants were second grade students from three primary schools in low socio-economic status areas. Using a…

We investigated the associations between teacher-rated and direct assessments of early elementary students' speech and language skills to explore whether using teachers as primary screeners yielded assessment data that reliably identified young students with language difficulties who many need a more comprehensive evaluation. We assessed first-…
