The oral language proficiency of students in early education is crucial as teachers draw on this as a resource when developing literacy. There is a need to better understand what this oral language resource consists of at school entry, particularly the diversity amongst children so as to address inequalities. This article reports a study on a key…

Background: Children's language abilities set the stage for their education, psychosocial development and life chances across the life course. Aims: To compare the efficacy of two preschool language interventions delivered with low dosages in early years settings (EYS): Building Early Sentences Therapy (BEST) and an Adapted Derbyshire Language…

Purpose: This study explores whether the quality of parent-child interaction is associated with language abilities cross-sectionally and longitudinally up to preschool-age among children with developmental language disorder (DLD). Method: Participants were 97 monolingual children with DLD and their parents from the Helsinki Longitudinal SLI study,…

Background: Recent research has shown that socio-emotional and language competencies are positively associated with each other. However, few studies have explored these associations for the second language competencies (L2) of young dual language learners (DLLs). Aims: This longitudinal study investigated possible bidirectional associations…

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…

Despite acknowledgment that language-minority children come from a wide variety of home language backgrounds and have a wide range of proficiency in their first (L1) and second (L2) languages, it is unknown whether differences across language-minority children in relative and absolute levels of proficiency in L1 and L2 predict subsequent…

A large linguistic distance exists between spoken Arabic and the Modern Standard Arabic (MSA) the literary language (a diglosia). Novice readers, therefore, struggle with the complex orthography of Arabic as well as the mastering of MSA. Here, we tested whether structured activities in MSA would advance kindergarteners' MSA aptitude by the end of…

This study examined the concurrent relations of English (EL) and heritage language (HL) proficiency to executive functions (EF) among low-income dual language learners (DLLs) from immigrant families. In a sample of 90 children (age = 38-70 months) from Chinese-speaking Chinese American and Spanish-speaking Mexican American families recruited from…

In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…

The population of Spanish-speaking preschoolers in the United States continues to increase and there is a significant need to develop psychometrically sound early language and literacy screening measures to accurately capture children's ability in Spanish. In this paper, we describe the innovative design and calibration process of the new…

This study examined the relations between problem behaviors and early learning outcomes among 138 children in dual-language pre-K programs who were identified at the beginning of the school year to be at risk for difficulties in early language and literacy development. Children's expressive and receptive vocabulary, listening comprehension, and…

We conducted two studies to examine the effects of an interactive read aloud and vocabulary intervention on the vocabulary knowledge of Spanish-speaking preschoolers living in the U.S. In Study 1, 68 children (n = 34 in the treatment group) and 6 parents in the treatment group received the intervention in Spanish at home, and in Spanish and…

Research Findings: The purpose of this study was to examine within-group individual differences in the code-related and oral language abilities of an economically stressed Spanish-speaking English language learner (ELL) preschool sample and to evaluate the predictive relationship of these differences to later listening comprehension. Latent class…

The DAPPLE (Dynamic Assessment of Preschoolers' Proficiency in Learning English) is currently being developed in response to a clinical need. Children exposed to English as an additional language may be referred to speech and language therapy because their proficiency in English is not the same as their monolingual peers. Some, but not all, of…

THIS STUDY WAS DESIGNED TO DEVELOP METHODOLOGICAL APPROACHES FOR OBTAINING AND ANALYZING CONTINUOUS EXPRESSIVE LANGUAGE SAMPLES USED BY PRE-KINDERGARTEN CHILDREN WHEN THEY COMMUNICATE WITH EACH OTHER. IT ALSO WAS TO CONSIDER MEANS FOR ANALYZING THESE SAMPLES THAT WOULD YIELD CERTAIN QUALITATIVE AND QUANTITATIVE METHODS. FOUR INVESTIGATORS WERE…
