This study examined the relationship between complexity, accuracy and fluency (CAF), using longitudinal data. Conducted from the perspective of complex dynamic systems theory (CDST), this research adopted four CAF general measures to track the development of five Chinese undergraduates' English speech over a 15-week period. LOWESS graphs supported…

The present study investigated the potential of writing in English as a foreign language (EFL) for language learning by manipulating cognitive task complexity based on related models and hypotheses. English essays written by 59 Chinese postgraduate EFL students from different subject areas were analysed with reference to writing complexity,…

This study investigates the effects of teacher-focused feedback (TF) and automatic writing evaluation (AWE) on global writing performance as well as syntactic complexity, accuracy, lexical diversity, and fluency (CALF) of English as a foreign language (EFL) learners' narrative and argumentative writings. The participants were randomly assigned to…

Most U.S. colleges and universities expect students to improve their writing ability by taking first-year composition (FYC) courses. In such courses, non-native English (L2) writers with diverse language backgrounds study alongside their native English (L1) speaking peers. However, it is not clear how different these populations are in terms of…

This study explores the effect of collaborative writing (CW) and peer feedback (PF) practices on subsequent individual writing assignments. Two groups of university students in a Spanish as a foreign language course experienced both CW and PF (Group 1 CW then PF; Group 2 PF then CW), and pre and posttests were analyzed for syntactic complexity,…

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…

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…

Speaking constitutes one of the main goals of learning a second language (L2). Despite the increasing attention on the role of planning and language transfer in L2 learning, the combined effect of using different languages and pre-task planning on language production remains unclear. This study investigated whether the use of different languages…

Previous research has documented positive effects of pre-task planning on task-based performance, commonly analyzed in terms of complexity, accuracy, and fluency, in an L2. However, the sources of planning have rarely been examined in the research of task-based language teaching. The present study explored EFL learners' oral performance across the…

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…

This study investigated the optimum task sequence for second language (L2) novice learners of English. One set of task sequences was manipulated using a deductive and theoretical SSARC (simplify-stabilize-automatize-restructure-complexify) model, and two sets of task sequences were manipulated based on a teacher's inductive classroom observations.…

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…

In the digital age, technology-assisted language learning (TALL) has emerged as a pivotal approach to enhancing English linguistic skills among college students. This study explores the effectiveness of TALL innovations in enhancing English linguistic skills among college students. Employing a mixed-methods approach, data were collected through…

We investigated how native and fluent users of English segment continuous speech and to what extent they use sound-related and structure-related cues. As suggested by the notion of multi-competence, L1 users are not seen as ideal models with perfect command of English, and L2 users not as lacking in competence. We wanted to see how language…

Aim/Purpose: This study examines the effects of the mobile-assisted task-based language teaching (M-TBLT) approach on EFL learners' oral production. It evaluates three key second language acquisition measures: complexity (syntactic and lexical), accuracy (error-free clauses and correct verb forms), and fluency (unpruned and pruned speech rates).…
