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 investigated the effect of the digital Down Syndrome LanguagePlus (DSL+) intervention on vocabulary outcomes through a school-delivered randomized controlled trial. A national sample of first graders with Down syndrome from 91 schools was allocated to an intervention group (n = 50), which received daily intervention for 15 weeks, or a…

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,…

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…

Purpose: The present study examined the nature of the effects (direct or indirect) of vocabulary, phonological and morphological awareness on early reading skills in the consistent Greek orthography by testing a unifying model of early reading development in a sample of 141 first-grade children. Method: Vocabulary, phonological and morphological…

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…

The acquisition of passives is well-studied in many languages, with evidence of crosslinguistic differences in the age at which passives are acquired. The aim of this study is to add to the existing knowledge of child acquisition of passives by providing data from Afrikaans and isiXhosa, two under-researched and typologically different languages…

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,…

Research on the implementation of CLIL at the onset of primary school is limited and has largely overlooked the role of other sources of individual differences. This study investigated the effects of the CLIL approach to English learning, together with the effects of out-of-school exposure to the language through media and other sources of…

Early vocabulary knowledge is vital for later reading comprehension and academic success. Studies have found that augmenting explicit teaching of word meanings with nonverbal visual aids, particularly pictures and gestures, assists young learners in building rich lexical representations. Research has focused on the effects of visual supports in…

We investigated the role of linguistic and cognitive processes in reading precocity from kindergarten to grade 2. A sample of 33 precocious readers was identified that did not differ on age, gender, and parental education to a control group of 259 typical readers. The effects of verbal ability were also controlled. All children were administered a…

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,…

It is well-documented that there is a strong relationship between vocabulary and reading comprehension in school-age children. Limited vocabulary knowledge can impact a student's reading achievement, as may be the case for school-age English Learners (ELs). This study aims to analyze the role of vocabulary in predicting reading comprehension…

Measures of decoding and oral language have been shown to predict early reading comprehension across a wide variety of languages, though the timeframe and strength of the predictions vary by orthographic depth. This study is the first to examine predictors of early reading in Vietnamese, a transparent orthography of Romanized letters and…

Purpose: First, we sought to extend our knowledge of second language (L2) receptive compared to expressive narrative skills in bilingual children with and without primary language impairment (PLI). Second, we sought to explore whether narrative receptive and expressive performance in bilingual children's L2 differed based on the type of contextual…
