Foreign language (L2) learners' speaking proficiency is often quantified using two dimensions: intuitive human ratings and analytical, linguistic complexity, accuracy, and fluency (CAF) indices. While previous research and assessment practices have predominantly focused on either the subjective approach to L2 speaking or the objective one, it is…

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…

Task design features have different effects on second language (L2) production and can be adopted for different pedagogical purposes. However, the synergistic effects of task features were left unexplored in the extant task-based literature. The present study investigated the synergistic effects of two task design features, namely, prior knowledge…

To test the predictive power of the SSARC (stabilize, simplify, automatize, reconstruct, and complexify) model of pedagogic task sequencing in second language (L2) writing development, the present study explores the performance of written decision-making tasks with varied levels of cognitive complexity in a simple-to-complex sequence in comparison…

Although a number of studies have been conducted to explore how various individual difference (ID) factors such as aptitude, motivation, and anxiety contributing to L2 learners' speech performance over a period of time of L2 learning, only a few examined the effect of the three ID factors on learners' L2 speech performances based on classroom…

This article reports on a study which examined the effectiveness of a 7-minute writing technique whereby students regularly wrote as much as they could in 7 minutes three times a week for a period of 10 weeks. The study was conducted with four classes of first-year and third-year students at a university in Vietnam. The study looked at the…

While there exists a considerable body of literature on task-based difficulty and second language (L2) fluency in English as a second language (ESL), there has been little investigation with French learners. This mixed methods study examines learner appraisals of task difficulty and their relationship to automated utterance fluency measures in…

The constructs of complexity, accuracy and fluency (CAF) have been used extensively to investigate learner performance on second language tasks. However, a serious concern is that the variables used to measure these constructs are sometimes used conventionally without any empirical justification. It is crucial for researchers to understand how…

This study aimed at exploring the impact of mentor text modelling on Iranian English as a Foreign Language (EFL) learners' accuracy and fluency in writing tasks with different cognitive complexity in comparison with two conventional approaches to teaching writing; namely, process-based and product-based approaches. To this end, 60 Iranian EFL…

Despite the stream of directives about improving students' English communicative ability from the Japanese Education Ministry since 2003 [1-4] significant development has remained elusive. One obstacle to communication (as an individual and a cooperative faculty) is the inflexible "one-size-fits-all" philosophy of commercial textbooks…

Recent literature in second language (L2) perceived fluency has focused on English as a second language, with a primary reliance on impressions from native-speaker judges, leaving learners' self-perceptions of speech production unexplored. This study investigates the relationship between learners' and judges' perceptions of French fluency under…

Applied linguists have identified three components of second language (L2) performance: complexity, accuracy, and fluency (CAF) to measure L2 development. Many studies researching CAF found trade-off effects (in which a higher performance in one component corresponds to lower performance in another) during tasks, often in online oral language…

Recently task-based language teaching has attracted many researchers', testers' and syllabus designers' attention and consequently a lot of studies are carried out in this field. This study was conducted in the task-based realm too. The main purpose of this study was to investigate the effect of teacher's presence on learners' performance in doing…

This study contributes to the research on learner autonomy by examining the relationship between Little's (1991) notions of "independent action" and "decision-making", input, and L2 production in computer-assisted language learning (CALL). Operationalizing "independent action" and "decision-making" with Dam's (1995) definition that focuses on…

The impetus of the present study was to scrutinize the impact of planning and proficiency on 172 EFL learners' written task performance regarding concept load, fluency, complexity and accuracy. Planning was operationalized at two levels: pretask planning (PTP) and online planning (OLP). Participants of this study were two groups, high and low…
