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,…

The reported study highlights the importance of an L2 curriculum integrating authentic linguistic and cultural input to promote learners' linguistic, communicative, and cultural competencies. Through content analysis, the researchers evaluated the linguistic and cultural authenticity of the Grades K-6 "Mandarin Matrix Curriculum"…

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…

Syntactic complexity has long been used to gauge language learners' performance, proficiency, and development, offering language teachers valid recommendations for syllabus design and materials development. Progress in syntactic complexity research foreshadows the imperative of measuring syntactic features at a high level of granularity, which…

One of the critiques of proficiency as defined by scales, such as that of ACTFL, is its lack of grounding in linguistic realities. Measures of complexity, accuracy, and fluency provide a route in which proficiency can be quantitatively measured by identifying linguistic correlates (see Brown et al., 2017; Long et al., 2012). This project aimed to…

The effects of learner- and task-related variables on second language (L2) writing syntactic complexity (SC) have been extensively investigated. However, previous research has rarely assessed the reliability of computational tools for analyzing the SC of L2 spoken production, and we know less about the effects of such variables on L2 speaking SC.…

Language immersion programs seek to develop multilingual, multiliterate individuals able to engage with academic content. Studies of immersion students' language development provide details regarding language proficiency and accuracy, yet they generally do not address how features of written, academic language, for example, syntactic and lexical…

Background: Bilingual assessment is particularly difficult in the very first period of children's second language (L2) exposure. This exploratory, longitudinal study examined L2 learning after 1 and 2 years of L2 exposure by young immigrants and how it is affected by their age at first exposure to the L2 (AoE). Method: Participants were 18…

This study investigates whether statistical learning ability, conceptualized as a cognitive ability to learn regularities implicitly, is a good predictor for L2 learners' online language processing performance. Native-English-speaking adults, as a control group, and native-Korean-speaking adult L2 learners of English participated. They completed:…

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,…

The research on language acquisition and retention has primarily focused on monolinguals and bilinguals, with comparatively few studies including trilinguals. To address this gap, the current study compares the acquisition and retention of a novel morphosyntactic rule in Spanish in twelve monolinguals, twelve bilinguals, and twelve trilinguals.…

Studies analysing the metatalk generated in collaborative writing (CW) tasks have primarily targeted secondary or adult students who wrote either in L1 or L2, and have seldom examined the process of their writing in two languages. Furthermore, these analyses have mostly focused on accuracy discussions and have ignored discussions aimed at making…

Task-based research has investigated the learning opportunities (e.g. language related episodes) that emerge during heritage and second language learner interactions during writing tasks. However, to date, it is unknown how these peer interactions involving heritage language learners contribute to written texts. Further, given the rise of social…
