While extensive research has explored Second Language Vocabulary Acquisition (SLVA) acquisition, there has been a lack of comprehensive bibliometric analysis on this topic. This study addresses this gap by investigating research trends and collaboration networks in SLVA over the past 24 years. Publications on SLVA were retrieved and analysed using…

Previous research shows that infants of parents who are more likely to engage in socially contingent interactions with them tend to have larger vocabularies. An open question is "how" social contingency facilitates vocabulary growth. One possibility is that parents who speak in response to their infants more often produce larger…

Code-switching occurs regularly in the input to bilingual children. Yet, the effect of code-switched input on language development is unclear. To test whether word learning would be affected by code-switching, Spanish-English bilingual children (N = 45, 19 boys, Mean[subscript Age] = 5.05 years; ethnicity: 37 Hispanic/Latino, six…

This systematic review surveyed research on the associations between sleep and the memory processes involved in word learning in infancy. We found only 16 studies that addressed this topic directly, identifying associations between infant sleep and the memory processes, the identification of word forms in running speech, and the stabilization and…

Subgroups of children with different speech profiles have been described however, little is known about the trajectories of speech development or stability of subgroups over time. This longitudinal study described both speech trajectories and subgroup stability of 22 autistic children, aged 2;0-6;11 years, over 12 months. Independent and…

This article reviews conversation analytic research on explanations in pedagogical interaction, particularly in language learning classrooms. In reviewing this literature, this paper aims to provide a comprehensive account of what is interactionally involved when giving pedagogical explanations so that future research investigating the…

This article presents an online application developed to improve vocabulary learning through games, quizzes and interaction with a chatbot. The application was tested experimentally on a sample of twenty proficiency-level students divided into two groups and tested on English vocabulary learning in two stages. In the first stage, the first group…

Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

How does one assess developmental change when the measures themselves change with development? Most developmental studies of word learning use either looking (infants) or pointing (preschoolers and older). With little empirical evidence of the relationship between the two measures, developmental change is difficult to assess. This paper analyzes…

Purpose: This study examined science achievement; science vocabulary knowledge; and the relationship between science vocabulary, language skills, and science achievement in school-age children with language/literacy disorders (LLDs) and typical language development (TD). Method: Thirty-nine sixth graders (11 with LLDs) completed standardized…

Purpose: The integration of mobile technology in ESL/EFL contexts has garnered significant attention from contemporary researchers, teachers, and learners due to the advancements in technology, dynamic features, and multimodal applications. With this growing interest, there is a need to synthesize the existing literature and identify current…

Purpose: The aim of the study was to describe the expressive sign vocabularies of a group of children learning Australian Sign Language (Auslan). Method: The spontaneous signs of 44 children aged 3.0-6.8 years enrolled in one early-years bilingual-bicultural educational program were documented using a new approach, the Handshape Analysis Recording…

Purpose: There are many aspects of words that can influence our lexical processing, and the words we are exposed to influence our opportunities for language and reading development. The purpose of this study is to establish a more comprehensive understanding of the lexical challenges and opportunities students face. Method: We explore the latent…

Comprehending texts in content areas can be challenging for students with learning disabilities (LD) because they may lack the necessary background and vocabulary knowledge needed to construct meaning from text. As more students with LD are educated in the general education classroom, it is necessary for teachers to implement strategies to…

Successful vocabulary acquisition hinges on the harmonious interplay of various factors. Despite some studies that have been conducted to examine the direct effect of self-regulation on vocabulary learning, few of them tapped into the relationship among self-regulation, motivational beliefs, vocabulary learning strategies and vocabulary…
