Research has demonstrated that features of lexical and lexicogrammatical use are important predictors of productive second language (L2) proficiency (e.g. Kyle et al. 2018). While some features of lexical use have been studied with L2s other than English (e.g. Tracy-Ventura 2017), multivariate lexical and lexicogrammatical approaches in these L2s…

This study examined second language (L2) learning difficulty of 13 Chinese grammatical constructions on the basis of teachers' perceptions and associated the L2 learning difficulty of Chinese grammatical constructions with teacher-perceived learner grammatical competence and with the instructional levels. A total of 77 experienced teachers were…

This chapter examines the lexical availability of students of Spanish as a foreign language (SFL) and observes how their semantic networks change as their proficiency in Spanish increases. The analysis focuses on 150 students with different levels of proficiency and the two centres of interest: "acciones y actividades habituales"…

The measurement of second language (L2) productive lexical proficiency has driven a great deal of research over the past two decades. Research has indicated that more proficient speakers and writers tend to use a wider range of words and that more proficient writers tend to use words that are more sophisticated (less frequent in reference…

The purpose of this paper is to investigate students' grammar performance and attitudes toward inductive and deductive approaches to teaching grammar in English. A mixed-method study in higher education tested the effectiveness of inductive, deductive, and a combination of both approaches on student performance on grammar tests using eight…

Frequency and proficiency have been found to play an important role in second language (L2) phrasal processing. However, existing research has largely focused on English and other European languages, with other commonly used languages, such as Chinese, being largely disregarded. To fill this gap, we carried out two experiments to investigate how…

The use of AI-powered chatbots has recently been extensively examined for second language (L2) learning. While their positive effects have been widely reported regarding L2 English learning, studies involving less commonly taught languages (LCTLs) are scant. The current study incorporated an AI chatbot called Iruda in L2 Korean teaching, to…

In this brief forum article, I draw from the disciplinary orientation of linguistic anthropology to discuss how a collection of linguistic and semiotic resources gets "enregistered" as the "language" for specific communicative activities. Enregisterment is an ongoing social and ideological process whereby a semiotic corpus gets…

The present study examines grammatical gender knowledge in offline production (gender marking on indefinite articles) and online gender processing (visual world paradigm) in adult second language (L2) learners of Norwegian with three different first languages (L1s): Greek, Russian, and Turkish. In particular, it investigates the role of the…

Second language acquisition (SLA) in English can be revolutionized by artificial intelligence (AI) because it can provide personalized learning methods for learning English. Although AI has made advancements in this area, the standard SLA systems that are familiar with often fail to provide real-time, personalized feedback that can enhance…

The present study performs a three-level meta-analysis to investigate the overall effectiveness of automated writing evaluation (AWE) on EFL/ESL student writing performance. 24 primary studies representing 85 between-group effect sizes and 34 studies representing 178 within-group effect sizes found from 1993 to 2021 were separately meta-analyzed.…

The present continuous tense can be problematic among L1 Thai learners due to the variation in contexts in which the tense can be used (Boonjoon, 2017; Khattiya, 2018; Kongthai, 2015). The present study aimed to examine the functional use of the English present continuous tense by L1 Thai learners under the theoretical framework of the…

The proficiency of English language in Thailand is considered as a crucial factor prioritized across various sectors to enhance the population's capacities. All educational institutions, from kindergarten to tertiary levels, emphasize the improvement of English competence through diverse pedagogical approaches and the application of the Common…

Background/purpose: Despite its informal setting, it is astonishing that the members of online English-speaking club (ESC) are adept at speaking. Employing a mixed-methods approach, more specifically a descriptive case study, this study aimed to evaluate the ESC contribution to its members' speaking competence development, to examine their…

Acquisition of the perfective marker "-le" in Mandarin Chinese is a daunting task for second language learners. To date, there has been no consensus on what it is about "-le" that makes it such a challenge to learners. This study investigates the acquisition of "-le" from both a lexical perspective and a discourse…
