Research into self-regulating capacity in vocabulary learning is recognized as a significant topic within the second language domain. The self-regulating capacity in vocabulary learning scale (SRCvoc; Tseng et al. 2006) is arguably the most widely used tool for assessing this construct. The common factor model, which is applied through…

Research comparing equal and expanding spacing schedules in relation to L2 single words is limited. Moreover, none of the existing studies has examined the learning of formulaic language. The current study aims to address this gap by investigating the impact of equal and expanding intervals on the long-term retention of L2 collocations in…

Domestic immersion (DI) is an effective context for postsecondary language learning, given that DI's instructor-curated environments promote meaningful second language use while providing abundant support for learners. However, DI is at present understudied within second language acquisition research, especially when compared to its more…

College-level deaf and hard-of-hearing (DHH) students and hearing students of English as a Second Language (L2) along with hearing native speakers (NS) of English were assessed in their knowledge of English resultative and depictive sentences. In "Kevin wiped the table clean," the resultative phrase "clean" indicates that the…

Neural Machine Translation (NMT) has gained increasing popularity among EFL learners as a CALL tool to improve vocabulary, and many learners have reported its helpfulness for vocabulary learning. However, while there has been some evidence suggesting NMT's facilitative role in improving learners' writing on the lexical level, no study has examined…

This study investigated how input frequency (i.e., type frequency and token frequency) and proficiency levels enhanced the perception of English nominal suffixes by first language (L1) Thai learners. Based on the Usage-based Account (Tomasello, 2003), it was hypothesized that input frequency, i.e., token frequency (frequency of derived forms…

Since its emergence, generative AI has significantly impacted various fields, including English language education. Numerous academic studies have investigated its capabilities in grammar correction, writing evaluation, and dynamics of user interaction. However, there have been insufficient investigations into whether texts generated by such AI…

This study aimed to propose a new method for scoring C-Tests as measures of general language proficiency. In this approach, the unit of analysis is sentences rather than gaps or passages. That is, the gaps correctly reformulated in each sentence were aggregated as sentence score, and then each sentence was entered into the analysis as a polytomous…

Establishing a cut score is a crucial aspect of the test development process since the selected cut score has the potential to impact students' performance outcomes and shape instructional strategies within the classroom. Therefore, it is vital for those involved in test development to set a cut score that is both fair and justifiable. This cut…

Multi-word expressions are formulaic language universals with arbitrary and idiosyncratic collocations. Their usage and mastery are required of learners of a second language in achieving naturalness. However, despite the importance of multi-word expressions to mastering a second language, their syntactic architecture and colligational…

This study examined the effects of watching gestures and lip movement on second language (English) listening comprehension. The participants were 30 high and 22 low proficient learners of English. There were six listening tasks combining two variables: modality and difficulty. The modality consisted of three types of assessments: Body (the upper…

Mastering correct pronunciation is crucial for effective Spanish language learning and communication. However, many existing language learning resources lack adequate coverage of pronunciation guidance and feedback mechanisms. This study aims to address this gap by developing SpanishBot, an innovative chatbot designed to facilitate the learning of…

This study explored the effects of listening-based lexical focus-on-form (lexical FonF) on the acquisition and retention of morphologically complex words. One hundred eighty-two adult English learners with two levels of English proficiency (higher and lower proficiency) from a public university in mainland China were assigned to three different…

Background/purpose: This study investigated the short-term and long-term impact of collaborative writing on lower-proficiency English as a foreign language (EFL) students in Saudi Arabia. It investigated whether co-authoring enhanced the writing standard, which areas effectively evolved and how effectively the students retained their writing…

In this mixed-methods study, we investigated the relationship between instructional approach, students' self-efficacy beliefs, and students' English language proficiency, as well as the perceptions of the instructor and students regarding problem-based learning (PBL) in a College English course in China. Using path analysis, we assessed the…
