Negation is a cornerstone of human language and one of the few universals found in all languages. Without negation, neither categorization nor efficient communication would be possible. Languages, however, differ remarkably in how they express negation. It is yet widely unknown how the way negation is marked influences the acquisition process of…

Although research on content and language integrated learning (CLIL) has shown that CLIL instruction may enhance students' second or foreign language learning compared to regular foreign language instruction, there are also studies that have indicated similar language development between CLIL and non-CLIL students. However, CLIL can be organized…

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…

The paper applies language management theory to study the interactions of international with local workers (simple management) and language policies (organised management) in 10 Czech video game studios. By longitudinally interviewing foreign game developers from Central-Eastern and Western Europe, as well as North and South America, I identified…

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…

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…

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…

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…

This true longitudinal study explored the lexical development of L2 university English major students in Thailand using two learner corpora. This study analyzed the natural learners' English language writing assignments from two writing courses and tracked their lexical development over a relatively long period (three years with five batches of…

Research has established the link between socioeconomic status (SES) and children's reading development. However, the theoretical mechanisms underlying the association between them have yet to be fully understood. Moreover, few previous studies exploring the mechanisms tapped both first language (L1) and second language (L2) at the same time. In…

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…

Foreign or second-language (L2) pre-service teachers (PSTs) are simultaneously learners and teachers of the target language, adding to the complexity of teacher education. How these two identities are intertwined with their pedagogical beliefs and dominant ideologies has not been fully investigated, especially with PSTs in longitudinal studies. To…

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…

Research on "parentese," the acoustically exaggerated, slower, and higher-pitched speech directed toward infants, has mostly focused on maternal contributions, although it has long been known that fathers also produce parentese. Given recent societal changes in family dynamics, it is necessary to revise these mother-centered models of…

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…
