This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

This study investigates the impact of Filipina domestic workers (FilDWs), a marginalized group in Hong Kong (HK), on HK children's language development. It focusses on FilDWs' influence on the second language (L2) English of bilingual HK primary school children attending an English Medium of Instruction school. The elements investigated are L2…

This research was conducted to investigate AI integration in the development and evaluation of English oral communication skills, within both academic and professional practices. This study used a mixed-methods design, combining data from a quasi-experiment with qualitative data collected through interviews with students and instructors. Results…

This longitudinal study made the first attempt to employ Latent Growth Curve Modeling to analyze the development of L2 speaking accuracy and fluency through online scaffolding as well as the dynamic relationship between L2 speaking performance and self-efficacy. From the perspective of Complex Dynamic Systems Theory, it tracked the development of…

Writing and its role in English as a foreign language (EFL) context has been one of the primary areas of focus for many years. The present study examined the effects of mobile-based concept mapping on EFL learners' writing fluency and motivation. To fulfill the objective, 70 upper-intermediate level Persian EFL learners were assigned into one…

Previous studies have explored the roles of metacognitive instruction and collaborative writing, separately, in English writing. Little attention has been paid to students' writing complexity, accuracy, and fluency (CAF). The present study aims to bridge this gap through investigating integrated writing performances based on the linguistic…

The purpose of this study was to explore the effect of the listener's education and occupation on intelligibility, comprehensibility (ease of understanding), and accentedness in speakers of Russian-accented American English (RA), Southern-accented American English (SA), and General American English (GAE). Native English listeners (N=126) rated…

Whereas scholars have extensively researched the pedagogical potential of 4/3/2 activities (i.e. increasing time pressure in task repetition) for enhancing second language (L2) fluency, its impact on L2 accuracy remains unclear. To help L2 learners improve both fluency and accuracy, the present study examined the effects of adding accuracy…

Students who learn the language of instruction as an additional language represent a heterogeneous group with varying linguistic and cultural backgrounds, contributing to classroom diversity. Because of the manifold challenges these students encounter while learning the language of instruction, additional barriers arise for them when engaging in…

This study aimed at investigating the impact of story-based extracurricular tasks on enhancing the speaking skills of EFL learners. The parameters of grammar, pronunciation, vocabulary, and fluency were examined. A pre-test/post-test one shot case study design was adopted. A sample of 20 students, enrolled in the common first year program at Jouf…

A great deal of research explores how implicit vs. explicit instruction affects second language learners' grammatical accuracy, generally finding that explicit instruction increases accuracy. However, no research to date has examined the impact of implicit/explicit instruction on learners' fluency. Additionally, nearly all the research has only…

Verbal Fluency (VF) task total scores are widely used in language attrition studies, but they do not provide insight into the processes underlying optimal performance. We analyse the efficacy of clustering (subcategories within a category) and switching (shifting between these subcategories) strategies in phonemic (PVF) and semantic (SVF) tasks.…

Text messaging is the most popular form of communication (Lionbridge, 2019; Ceci, 2022), and mobile phone ownership is high, especially among university students (Chen & Denoyelles, 2013). Research on mobile language learning is increasingly found on the forefront of computer-assisted language learning (CALL) (Loewen et al., 2019; Stockwell,…

This study aimed to investigate whether and how willingness to communicate, communication in English anxiety, behavioural inhibition and action predict perceived second language (L2) fluency. The study also looked at whether L2 proficiency moderates the strength of relationships between these affective factors and L2 perceived fluency. One hundred…

Automatic Speech Scoring (ASS) has increasingly become a useful tool in oral proficiency testing for Second Language (L2) learners. However, limited studies investigate the alignment of ASS indices with the Complexity, Accuracy, and Fluency (CAF)--the three dimensions in evaluating L2 speakers' oral proficiency, and the subsequent impact indices…
