There is a current 'theory crisis' in language acquisition research, resulting from fragmentation both at the level of the approaches and the linguistic level studied. We identify a need for integrative approaches that go beyond these limitations, and propose to analyse the strengths and weaknesses of current theoretical approaches of language…

Derivational knowledge, the ability to understand and produce derivatives of a word, is essential for vocabulary learners to expand their lexical knowledge. Earlier research (e.g., Schmitt & Zimmerman, 2002) has shown that L2 learners may have limited ability to produce derivatives compared to L1 speakers. However, the degree to which…

Studying the oral language growth of Spanish-speaking preschoolers in the United States is increasingly important given the critical role early language development plays in reading outcomes. In this article, we report on the Spanish and English growth trajectories observed in 124 bilingual preschoolers collected over 2 years in 36 classrooms…

This paper traces recent theorisation stemming from the multilingual turn and brings this into dialogue with assemblage thinking, discussing the critical potential of bringing these perspectives together to explore what language is and how it is understood. The argument maps salient features of the multilingual turn which have extended the fields…

There is a growing body of research from various perspectives in heritage language (henceforth HL) acquisition as an emerging field. Some studies proposed that HL acquisition is a differential acquisition compared with the baseline language (i.e., the language spoken by the parents or caregivers) (Kupisch & Rothman, 2018; Dubiel &…

Utilizing the framework of the L2 motivational self-system as its theoretical foundation, this study focuses on a total of 52 students who discontinue their English learning within a senior high school in Yangzhou, Jiangsu Province. The primary objective of this study is to discern the underlying motivations prompting students to discontinue their…

Despite some research attention given to expatriate native-English-speaking teachers' (NESTs) identities and the national educational ideologies that have led to their international recruitment, surprisingly little research has addressed their career trajectories as TESOL professionals. To address this gap, this case study explores the career of a…

Purpose: We examined the properties of mean length of utterance (MLU) in Czech, a morphologically complex Slavic language. We compared the scores of MLU calculated in different units and based on different sample lengths and assessed its validity against another transcript and test-based measures. Method: One hundred nine children were recorded…

The acquisition of quantifiers is a central topic in cognitive science. The present study investigated the emergence, frequency, and non-target-like production of the universal quantifiers "all," "every," and "each" in child English from a linguistic perspective, based on the data from longitudinal naturalistic…

This paper investigates the linguistic and semiotic resources that NGO coaches draw on to create safe spaces in their English language lessons for psycho-social support in refugee settings. We do so by applying the rapidly developing concept of translanguaging, using data from a multi-site linguistic ethnography study in an NGO in the Kurdistan…

The purpose of this paper is to describe and reflect on the position of what are called second additional languages in the language teaching landscape of South African schools. This landscape is crowded, with different South African languages vying for attention. Amidst efforts to increase the number of learners who offer an African language as…

The era of globalization and information and knowledge in which we find ourselves requires Higher Education to develop English-speaking proficiency in its students to adequately respond to academic and occupational challenges, taking advantage of the virtues of the variety of resources offered by technology. YouGlish is an online oral dictionary…

This study examines the extent to which verb argument construction (VAC) based indices of syntactic complexity could predict four different writing task conditions: a simple task with no repetition (S + NR), a simple task with repetition (S + R), a complex task with no repetition (C + NR), and a complex task with repetition (C + R). Ninety-six…

This study aimed to answer an ongoing validity question related to the use of nonstandard English accents in international tests of English proficiency and associated issues of test fairness. More specifically, we examined (1) the extent to which different or shared English accents had an impact on listeners' performances on the Duolingo listening…

The recent surge in studies on collaborative writing (CW) has provided valuable insights into the product and process of writing. When writing together, adults tend to produce better texts and generate and resolve a large number of language-related episodes (LREs). Also, analyses of the dialogues of collaborative writers show that learners are…
