This dissertation is a quantitative analysis of language proficiencies through the lens of the dynamic model of multilingualism, using survival analysis to evaluate time until thresholds of foreign language proficiency are reached and nonparametric tests (Wilcoxon signed rank and Kruskal-Wallis) to compare proficiencies at distinct time intervals…

This longitudinal study (data collected from 2019 to 2023) examines the relation between Spanish-English bilingual Latino toddlers' (n=46; F=22; M=24) early gesture production (Mage=18.67 months; SD[subscript age]=1.02) and later language skills (M[subscript age]=36.87 months; SD[subscript age]=0.81). Video recordings at child-age 18-months…

Studies of non-linguistic statistical learning (SL) have often linked performance in SL tasks with differences in language outcomes. Most of these studies have focused on Western and high-income educational contexts, but children worldwide learn in radically different educational systems and communities, and often in a second language. In the west…

Non-word repetition tasks are widely used to assess phonological short-term memory (PSTM). Results of previous research on the performance of monolingual and bilingual children in PSTM tasks are inconclusive. Although in some studies bilinguals did outperform monolinguals in the repetition of non-words, most studies reported comparatively weak…

The practices of sorting things out and bringing things together, which I summarise under the term relanguaging, sit between fluid, situated languaging practices and the administrative standard grid in education that relies on bounded, named languages. Relanguaging, I argue, was invisible to socio- and applied linguists' analytical vision because…

In L1 attrition research, it's recognized that a previously acquired language can transform under the influence of a newly acquired one. However, the precise L1-L2 relationship is intricate and warrants further study. Some research suggest that L2 mastery might reduce L1 proficiency, while others show that both languages can be maintained. Age of…

Second language proficiency may be related to first language acquisition (Ganschow & Sparks, 1991), but relatively little is known about the relation between first and second language grammatical proficiency in primary school children who are in their first stages of foreign language learning. This study aims to determine whether differences…

Codeswitching is a common feature of bilingual language practices, yet its impact on word learning is poorly understood. Critically, processing costs associated with codeswitching may extend to learning. Moreover, verbs tend to be more difficult to learn than nouns, and the challenges of learning verbs could compound with processing costs…

The research report describes the ability of Kazakh preschool children to tell narratives relating to mental states, and the connection with theory of mind tasks about false beliefs. Three groups of preschool children (N = 29; 3-, 4-, and 5- year-olds) from the city of Almaty were tested in the Kazakh language. The results show very high…

Paradis' (2023) keynote article is a timely documentation of the ongoing shift in focus within childhood bilingualism research from investigating the factors that modulate majority or second language (ML/L2) attainment (Chondrogianni & Marinis, 2011) to understanding the sources of variation that lead to minority heritage language (HL)…

The English proficiency gap is one of the most significant problems for young students in South Korea as it widens inequality by limiting opportunities for their future. One unique learning center, located in the under resourced area in South Korea, has been available at cost-free to enhance language development. This qualitative case study aims…

The unprecedented time of COVID-19 has called schools and educators worldwide to think of transferring education from face-to-face based to become more digital oriented. This transformation has pros and cons. Scholars in the field are questioning investigating the challenges that online learning entails; however, one of the issues still not fully…

This study explored the efficacy of video podcasts (VODcasts) in fostering whole-language learning among college EFL students. Employing a quasi-experimental design with pre-tests, post-tests, and a control group, the research compared the effects of a one-year remedial instruction program. The experimental group received instruction incorporating…

Although most children learn to communicate in their first language (L1), there is normal and expected variation in their rate of acquisition across all components of the language system. Until recently, most second language acquisition and second language (L2) researchers have assumed that individual differences (IDs) in L1 acquisition are small…

With the rapid globalization occurring all around the globe, educational landscapes also underwent some dramatic shifts. One of those notable shifts is the rapid transition from teacher to student-centered approach. In Indonesian EFL productive language learning contexts; speaking and writing, problem-based learning activities can enable learners…
