Research Findings: Early childhood teachers' talk is a key ingredient in children's early language and literacy development, but there has been little systematic synthesis of observational studies that examine relationships between teacher talk and child oral language. In this systematic review of 54 studies, we investigate and synthesize the…

The purpose of this study was to compare developmental trajectories of oral language acquisition of children who are deaf and hard of hearing (DHH) and children with typical hearing across the preschool years. Thirty children who are DHH who use amplification and spoken language and 31 children with typical hearing completed an early language and…

Building on previous studies investigating the multidimensional nature of lexical use in task-based L2 performance, this study clarified the roles that the distinct lexical features play in predicting vocabulary proficiency in a corpus of L2 Oral Proficiency Interviews (OPI). A total of 85 OPI samples were rated by three separate raters based on a…

This paper represents a summary and discussion of the three studies presented at the morning session of the Fall 2022 JALT Vocabulary SIG. The papers, which were written by Ali Al-Hoorie, Masaki Eguchi, Derek Canning, Stuart McLean, Christopher Nicklin, and Joseph Vitta, represent a range of topics and study designs that are common in recent…

The development of 4- to 6-year-olds' narrative skills was investigated in relation to their receptive vocabulary, grammar, and home literacy environment. At Time One, 82 children aged 4 to 6 years completed standardised assessments of cognitive ability, vocabulary, and grammar. Narrative production and comprehension were assessed by the narration…

This study aimed to determine if the T3 framework for technology in education impacts students' vocabulary learning, oral language, and reading comprehension, specifically for students labeled as English Language Learners (ELLs). Students were asked to learn two root words a week for four weeks. During each instructional week, students were asked…

Developing L2 learners' productive mastery of vocabulary is a challenging task. Recent research has called for greater attention to understanding how receptive vocabulary may be transformed for productive use (Schmitt, 2019). Using a design-based research methodology, this study investigated adult ESL learners' productive oral vocabulary…

Young children with autism spectrum disorder (ASD) present with a broad range of spoken language abilities, as well as delays in precursor skills such as gesture production and joint attention skills. While standardized assessments describe language strengths, the Communication and Symbolic Behavior Scales (CSBS-DP) is a particularly robust…

Across languages, children map words to meaning with great efficiency, despite a seemingly unconstrained space of potential mappings. The literature on how children do this is primarily limited to spoken language. This leaves a gap in our understanding of sign language acquisition, because several of the hypothesized mechanisms that children use…

This action research study aimed to improve reading with understanding in a lower primary classroom in Fiji. Five emergent readers were selected through an examination of class running records. Peer observation, student worksheets, and class running records were utilized to collect data. The data analysis revealed that when teachers implement…

Family engagement and family literacy are two of the most important or components for building a strong foundation for children's academic success. Family engagement is about spending quality time with children every day by talking, playing, and asking questions, which builds bonds and promotes language development. Family literacy supports…

The study investigates how the test modality (spoken or written) of classroom weekly quizzes influences vocabulary learning strategies and facilitates learning the spoken and written knowledge of form-meaning connection in L2 words. Japanese university students in academic English courses were assigned to two experimental conditions (spoken test…

Eighty Japanese learners of English as a foreign language encountered 40 target words in one of four experimental conditions (three encounters, six encounters, three encounters with talker variability, and six encounters with talker variability). A picture-naming test was conducted three times (pretest, immediate posttest, and delayed posttest)…

Purpose: The aim of this study was to examine the degree to which quantitative aspects of dosage (dose, dose frequency, and total intervention duration) have been examined in intervention studies for children with developmental language disorder (DLD). Additionally, to establish the optimal quantitative dosage characteristics for phonology,…

While research has established a close relationship between children's oral vocabulary and reading ability in Chinese, the nature of this relationship is not clear. This study aims to examine if vocabulary knowledge of Chinese words facilitates learning novel orthographic forms during independent reading. We also investigate whether such oral…
