The Mandarin resultative verb compound (RVC; e.g., "tui dao" "push fall" and "pa shang" "climb ascend") encodes complex events composed of an initiating action and resulting activity or state. This study investigated when Mandarin-speaking children acquired this language-specific device. Specifically, we…

This paper presents the effects of using digital games on improving language learning in Tanzanian preschools. A gamified learning prototype system was developed for making alphabetical sound articulation more engaging and fun. The study was conducted with twelve preschools in Tanzania. The results revealed that preschoolers' learning performance…

Pronunciation learners can benefit from peer feedback in a Computermediated Communication (CMC) environment that allows them to notice segmentals and suprasegmentals. This paper explores the intelligibility judgments of same-L1 peers using P-Check (Version2, https://ver2.jp), a Learning Management System (LMS) plug-in that aggregates peer feedback…

The United States has witnessed a rise in dual language immersion (DLI) programs in recent years, with instruction delivered both in English, the majority language spoken in the wider society, and in another language, often referred to as the partner or minority language. But while accountability mandates have focused on students' performance in…

This review article presents evidence for the claim that frequency effects are pervasive in children's first language acquisition, and hence constitute a phenomenon that any successful account must explain. The article is organized around four key domains of research: children's acquisition of single words, inflectional morphology, simple…

Cognitive linguists argue that certain sets of knowledge of language are innate. However, critics have argued that the theoretical concept of "innateness" should be eliminated since it is ambiguous and insubstantial. In response, I aim to strengthen theories of language acquisition and identify ways to make them more substantial. I…

The purpose of this project was to investigate the effectiveness of a language-focused professional development programme on the knowledge and behaviour of preschool practitioners (sometimes called early years practitioners) in the UK. In Study 1 we determined whether the training received by practitioners is effective in improving their knowledge…

The purpose of this study was to explore the use of code-switching in the narratives of dual-language Latino preschoolers, specifically by examining its incidence, types, functions, and grammaticality. Previous work has investigated code-switching in younger children and in older children and adults, but relatively little work has investigated…

Language development in early childhood education and care (ECEC) has received increased policy attention in the past 20 years. Yet, few empirical studies have explored language assessment from the standpoint of ECEC teachers. Transnational organizations, such as the Organization for Economic Co-operation and Development (OECD), have increased…

Purpose: This study examined the use of African American English (AAE) among a group of young Latinx bilingual children and the accuracy of the English Morphosyntax subtest of the Bilingual English-Spanish Assessment (BESA) in classifying these children with and without developmental language disorder (DLD). Method: Children (N = 81) between the…

Translanguaging through story documents the progression of an emerging bilingual preschooler who draws on his full linguistic repertoire to story his experiences with others. Over the course of the school year, Diego progresses in his ability to tell a complete story in both English and Spanish. Repeated engagement in storytelling provides the…

The quality of early care and education affects a wide range of children's experiences and developmental outcomes. Family Child Care (FCC) is no exception, and attention to increasing the quality of Family Child Care is needed. The purpose of the current study was to examine an experimental case of intensive Professional Development (PD) in FCC…

Quantificational elements such as some pose a challenge to young language learners, given their vague meaning and ability to take on an upper-bounded interpretation (relative to "all") in certain contexts. The challenge is enhanced when a child is acquiring multiple languages that do not share a one-to-one mapping between their lexical…

This book will provide school personnel with functional information and the necessary academic tools to manage the instructional needs of children with auditory disorders -- either peripheral hearing loss or auditory processing disorders. Treatment strategies to help mitigate the detrimental effects of hearing disorders in the classroom are…

Research Findings: This study used the Theoretical Domains Framework (TDF) to examine barriers to teachers implementation of a supplemental academic language curricula. Despite high satisfaction with this scripted curriculum, three past studies indicated heterogeneity in teachers fidelity of implementing the curriculum as well as difficulty going…
