In response to calls for an assessment tool that provides a separate performance dimension from the linguistic quality-oriented measures of complexity, accuracy, and fluency (CAF) and guided by systemic functional linguistic (SFL) theories, this study introduces a set of fine-grained objective measures of communication/content/function…

Previous research has shown that task repetition can positively affect L2 oral performance. However, few studies have explored the effects of task repetition on young EFL learners' production. Also, task repetition research has paid little attention to effects of "spacing" examined through longer time intervals between the two occasions…

This study reports on anxiety, enjoyment, and breakdown fluency of L2 English learners under the monologue and dialogue conditions using an idiodynamic approach. Eight Mandarin-speaking undergraduates from a top university in China voluntarily participated in the study, with half completing in a monologue condition and the other half in a dialogue…

The development of L2 utterance fluency has been extensively researched, whereas that of cognitive fluency has rarely been examined. This study investigated the longitudinal development of L2 utterance and cognitive fluency and their relationship. Thirty-one Chinese learners of English completed speaking tasks and a set of tasks for cognitive…

The current study investigated disfluency and self-repair in L2 presentational and interpersonal speech to determine whether speech modes may affect L2 self-repair. Knowledge of self-initiated repair behavior in L2 speech is particularly relevant for understanding psycholinguistic processes of L2 speech production. Different speech modes, such as…

This study compared the effects of task repetition only (TR), task repetition with grammatizing (TR+GR), and grammatization with no task repetition (GR) on 94 EFL learners' oral task performances. Participants' productions were measured both in terms of complexity, accuracy, and fluency as well as receptive knowledge (measured by an error…

This study explores the application of the task-based teaching method in English education, particularly from the perspective of big data. Traditional English teaching models often fail to meet the diverse needs of students, with the task-based approach, despite being student-centered, encountering challenges such as task difficulty control and…

The current study examined the effects of task condition (TC; single vs. dual) and proficiency level (PL) on self-monitoring of second language (L2) speakers. Data were collected from sixty-six female L2 learners of English performing two speaking tasks under two task conditions. While performance in the single-task condition involved only…

This study investigates the differential effects of a task-based inside-school intervention and an outside-school project intervention on the development of speaking skills of 56 beginner second language (L2)-learners. The study extends previous research by looking at development across multiple occasions instead of two (i.e., a pretest and…

Task-based language teaching (TBLT) and instructed second language acquisition (ISLA) have much in common in terms of theory, research, and educational relevance. The distinguishing characteristic between the two is that TBLT adopts communicative tasks as the central unit for instruction and assessment, whereas ISLA comprises a broader range of…

Research is scarce about the lexical processes undertaken by thousands of L2 learners worldwide who already command one or more languages. Some aspects involved in lexical organisation and production, such as clustering and switching, have been traditionally approached through manual methods, which depend on subjective judgments of semantic…

The impact of task complexity on integrated writing performance is under-researched. This study purports to investigate the effect of graph complexity and planning time on graph writing performance as well as graph description strategies. Ninety-six EFL learners of English were assigned into three groups to examine the effect of three planning…

For many people, learning a second language as an adult is a challenging endeavor. Much interest in the study of adult second language learning has concerned the type of input that learners receive in their second language, with findings suggesting that second language learners are often exposed to a register of speech called 'foreigner talk' that…

Researchers have been investigating the effects of different planning conditions on learners' second language (L2) writing performance. However, whether such effects differ regarding specific planning conditions and task complexity has remained underexplored. This study examined the effects of pre-task planning (PTP) versus unpressured online…

Students studying in beginning level foreign language classrooms often lack the opportunity to speak spontaneously (Kogan, 2023). Task-Based Language Teaching (TBLT) is a pedagogical approach to language instruction that advocates for the use of tasks to develop learners' second/foreign language (L2) abilities. Games can act as tasks that prepare…
