Studies looking into second language development have shown that findings about a group of learners cannot be transferred to individual learners. In this study, we explored ways to meaningfully group individuals starting from the data and investigated whether this grouping can give extra information about learning trajectories that goes beyond the…

Well-being development in young people's formative years is crucial for their transition to adulthood. While research on well-being in formal education contexts is expanding, little attention has been paid to out-of-school educational settings, particularly supplementary tutoring for disadvantaged students. Adopting Sirgy's concept of positive…

Because of the need to provide fine-grained longitudinal diagnostic feedback, longitudinal cognitive diagnosis is an emerging approach that integrates cross-sectional cognitive diagnosis models (CDM) with longitudinal data analysis techniques. By adopting the generalized longitudinal higher-order log-linear CDM, this study attempted to track the…

In this paper, we report a longitudinal study of the effects of procedural task repetition on learners' task performance (i.e., syntactic complexity in relation to lexical complexity). We investigated how task repetition results in differences at the group and individual level across each task interval (T = 7). Intermediate-level Saudi learners of…

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…

Studying abroad entails international students' identity (trans)formation and social network development, but individuals' decisions and choices while engaging in these processes remain underexplored. Informed by the notion of agency in second language socialization theory, this longitudinal case study examined the interplay of identity and social…

This study adopted a three-wave random intercept cross-lagged panel model (RI-CLPM) to explore the longitudinal reciprocal relationships between social support and engagement in EFL learning among Chinese high school students. Two samples, including 3505 students (Sample 1 = 1794; Sample 2 = 1711), were tracked with their perceived social support…

Background: Differentiating typical language development (TD) and developmental language disorder (DLD) in a bilingual context is difficult. The societal language is often the only mutual language of the child and the SLT. It has been shown that when assessing second language (L2) performance using tools developed for monolingual children,…

This study investigates the longitudinal development of language attitudes towards Catalan and Spanish over a five-year period in the transition from primary to secondary education of a sample of students (N = 1,143) in Catalonia and Aragon. Two research questions were investigated: (1) How do language attitudes develop over time? and (2) How do…

Teachers of all subjects and grades must remain aware of the linguistic and cultural diversity among their students, as second language learners often experience educational disadvantages. Therefore, (pre-service) teachers must acquire pedagogical language knowledge and skills in linguistically responsive teaching (LRT), and develop positive…

Collaborative writing is a pedagogical activity increasingly used in second language education. Despite the increased research on L2 students' participation in collaborative writing, scant attention has been paid to student engagement in project-based collaborative writing and the possible engagement changes. This article reports on a longitudinal…

In this study, we conduct a longitudinal experiment to explore the effects of adaptive phonetic training on the identification of the English vowels /i/ and /I/ by learners in China. The vowel /i/ in English has a low F1 value, a high F2 value, and a long duration. In contrast, the vowel /i/ has a high F1 value, a low F2 value, and a short…

Many researchers have acknowledged the benefits of the production-oriented approach (POA) in teaching English as a Foreign Language (EFL) writing. However, the impacts of POA on students' foreign language writing anxiety and English writing performance were still under-researched. Therefore, this longitudinal quasi-experimental study investigated…

English-medium instruction (EMI) has burgeoned alongside two decades of L2 self-regulated learning research. In both areas, listening remains under-researched, longitudinal designs are under-employed, and in-depth studies are necessary to unpack learner development. In a context believed to initiate self-regulated learning, the current study…

For decades now, researchers and academics have lamented the mismatch between the representation of English in the classroom and the way the language is used in real-world contexts. Much of teaching is bound by curricula that determine not only the contents of their teaching but also the materials and assessment methods they use, they are crucial…
