Despite the well-established role of lexis in proficiency in the four skills, a great deal of research has focused on the importance of vocabulary breadth and depth in reading. Therefore, the neglect of productive skills has motivated recent calls to inspect the impact of lexical dimensions on writing ability. Using Partial Least Squares…

While CLIL programmes have been extensively researched for their impact on L2 learning outcomes, the relationship between young learners' L2 proficiency and subject knowledge has received less attention. This study aimed to address this research gap by examining the science content knowledge of two cohorts of Grade 5 students (n = 100) from two…

This study examined the effects of involvement load-based tasks on vocabulary learning in a foreign language, as well as the extent to which task effects are predicted by learners' metacognition (i.e. metacognitive knowledge and regulation). A total of 120 Chinese university students of English as a foreign language (EFL) were randomly assigned to…

Self-assessment is an alternative assessment that can assess one's language ability, and it has been widely used, especially in classroom contexts. However, recent research has suggested different results regarding the correlation between student self-assessment and language performance. The accuracy of student assessment depends on various…

Usage-based theories of language development underscore the importance of children using language to learn language. Few investigations have applied usage-based theories to dual language learners (DLLs), who comprise a growing share of children attending early education programs in the U.S. Three studies were carried out to investigate the role of…

The purpose of this exploratory study was to examine the longitudinal, bidirectional relations between receptive and expressive Spanish and English language and internalizing and externalizing behavior problems in a sample of 97 preschool children from Spanish-speaking, homes who were enrolled in a U.S. Head Start program. Eight cross-lagged path…

The number of learners seeking to acquire an L2 by means of apps is ever-increasing. This study examined the effectiveness of using the app "Mondly" for the acquisition of L2 English vocabulary while accounting for differences in the acquisition of receptive and productive aspects of word knowledge. Twelve Danish young learners (aged…

This study examines the relationship between developing writer's vocabulary breadth, vocabulary depth, and writing abilities. Participants were EFL Chinese junior-high students, of whom there were 120 Grade 8 and 147 Grade 9 students. Measures included tests of vocabulary size, word association, and morphological awareness. Students' writing…

Language Instruction, especially teaching and learning English for specific purposes (ESP) with Computer-Assisted Language Learning (CALL) has grown in popularity for over a decade. Task-based Language Teaching (TBLT) is one of the appropriate teaching approaches used to make CALL more effective. This study attempts to develop, implement, and…

Research Findings: The aim of this study was to construct and validate "English Picture Vocabulary Test (EPVT)" that aimed to assess the very young learners' (VYLs) receptive and expressive vocabulary knowledge for specific content areas in English as a foreign language (EFL). In this context, EPVT was created in several stages. One of…

This paper examined to what extent causal explanation speaking tasks (CESTs) are cognitively appropriate for assessing young language learners' (YLLs) L2 speaking. Ninety-six YLLs (48 from Grade 4 and 6 each) in China performed two CESTs in both L1 (Chinese) and L2 (English). They also completed receptive and productive L2 vocabulary size tests.…

The robust relation between maternal education and child language that is observed in monolingual populations has not been reliably replicated among bilingual children from immigrant families in the United States. We hypothesized that a variable that operates in immigrant populations--the language in which mothers achieved their highest level of…

The present study explored the relationship between amount of dual language exposure, parents' language quality and bilingual competence among Chinese American children with autism spectrum disorder by using a cross-sectional correlational design. Thirty parent-child dyads participated in this study. Survey and observational data were collected…

This study examines low-intermediate to advanced ESL learners' awareness of semantic prosody. Semantic prosody is a word/unit association that expresses an attitudinal meaning (described as favourable, neutral, unfavourable), which emerges from the word's typical lexical environment. Sensitivity to and awareness of such associations is an…

This study investigated the learnability of multiple word knowledge aspects and the relationship between the word knowledge aspects. A total of 261 Thai high school students were measured on receptive and productive word knowledge aspects: word parts, the form-meaning link, and collocations. The current findings indicated that word parts are…
