Observational studies comparing child outcomes in early care and education classrooms of differing quality are often confounded by between-child differences. A within-child design, tracking children across contexts, can identify the effects of quality with less confounding. An analysis of Australian children (N = 1128, mean age 5 years, 48%…

Children continuously engage in developing theories about how the world works as they inquire through play and interactions with others. In this study, we investigated children's in-process thinking in the form of working theories about language as they participated in engagements around dual language picturebooks in an afterschool club. Our…

Two distinctive types of complex predicates found in English are separable verb-particle combinations ("particles") and adjectival resultatives ("ARs"). Snyder ties both to the positive setting of the Compounding Parameter ("TCP"). This predicts that during the acquisition of a [+TCP] language, any child who has…

This practical book will help literacy teachers operationalize research on culturally sustaining pedagogy (CSP) to reach all students. The authors guide pre- and in-service educators in creating classroom environments and learning experiences that foster students' literacy and language development, engagement with school, and critical…

This quantitative study evaluated how teaching models for language acquisition--the Integrated, the Stand-Alone and the Mixed Model--and student characteristics--gender and disability status--relate to growth in language skills among ELL students. In this study, the New York State English as a Second Language Achievement Test scores of the…

The purpose of this study was to determine whether there is a difference in the vocabulary knowledge of Spanish-speaking English Learners (ELs) when controlling for developmental language norms. This research was essential given the multitude of literature indicating the connection between vocabulary skills and later academic success and the…

Data-driven learning uncontroversially plays a role in human language acquisition--how large a role is a matter of much debate. The success of artificial neural networks in NLP in recent years calls for a re-evaluation of our understanding of the possibilities for learning grammar from data alone. This dissertation argues the case for using…

Deaf children of hearing parents (DOH) are at risk for early language delays (ELD) due to environmental and etiological factors, compounding the previously reported higher incidence of ELD in deaf children of deaf parents (DOD) compared to the general population. Archival data from the online database of the Visual Communication and Sign Language…

This study aims to compare the effects of "questioning with minimal evaluation" (PE) and "prompt-evaluate-expand-repeat" (PEER) used in dialogic reading (DR) on children's language development. This study included 119 typically developing (TD) and 107 Chinese children with autism spectrum disorder (ASD) by using a pre- and…

The paper presents the first comprehensive look at the language development of Romani-speaking children from resource-poor Roma communities in several European countries. 250 participants aged 3- to 10-years participated. The experimental tasks assess knowledge in eight key areas of grammar and morphology, including fast mapping of novel items.…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

This study explores the perspectives of the two authors, who have very different language backgrounds, reflecting the subtleties of first and additional language development. We distinguish between a 'literacy-track' (i.e. starting from written language) and an oracy track (starting from spoken language). We draw on duoethnography for our dialogic…

In their first year, infants begin to learn the speech sounds of their language. This process is typically modeled as an unsupervised clustering problem in which phonetically similar speech-sound tokens are grouped into phonetic categories by infants using their domain-general inference abilities. We argue here that maternal speech is too…

This research investigates the development of constraints in word learning. Previous experiments have shown that as infants gain more knowledge of native language structure, they become more selective about the forms that they accept as labels. However, the developmental pattern exhibited depends greatly on the way that infants are introduced to…

Using a sample of 1,117 families living in low-wealth rural areas, the current study focused on how home literacy practices for 3-year-old children were related to the children's language skills at ages 3 and 4. Three types of home literacy practices were explored: parent-to-child literacy practices, child literacy practices, and parent literacy…
