The interactions among cognitive, affective, and linguistic factors have received scant attention in task-based writing research. To address this gap, this study aims to examine the relationships among task complexity, task motivation, task engagement, and syntactic complexity in second language (L2) writing. One hundred L2 learners enrolled in an…

Comprehensibility has emerged as a useful and intuitive means of globally evaluating second language (L2) speakers in many research and instructional contexts. In most cases, L2 speakers' comprehensibility is assessed by external listeners who do not engage in extensive communication with the speakers, even though the degree to which a speaker is…

This article examines how second language (L2) interactional competence is manifested in students' use of "and"-prefaced turns when doing meaning-focused oral tasks in pairs and small groups. Drawing on video recordings from English-as-a-foreign-language upper-secondary classes recorded in Czechia and Finland, 86 sequences involving…

Concept-based language instruction (C-BLI) is a pedagogy guided by sociocultural theory, which has been shown to be effective in facilitating second language learning. Typical activities include materialization by using a schema for a complete orienting basis of an action (SCOBA) and languaging, through which learners' internalization of…

This study investigated the impact of synchronous computer-mediated communication (SCMC) mode and familiarity with partners on learner engagement in second-language task-based interaction, and whether learner engagement is linked to subsequent joint-written-text quality. Ninety-eight Vietnamese learners of English were assigned into (±) familiar…

Task-based research has shown the benefits of using tasks in various instructional contexts across different age groups. Although task-based language teaching promotes language learning through authentic real-world tasks, previous research has mainly used controlled pedagogic tasks. The current exploratory, intact-classroom, multi-case study…

This study examined how mode of input affects the learning of pronunciation and form-meaning connection of second language (L2) words. Seventy-five Japanese learners of English were randomly assigned to 1 of 3 conditions (reading while listening, reading only, listening only), studied 40 low-frequency words while viewing their corresponding…

Learner corpus studies using syntactic complexity as a construct for characterizing learner proficiency have found that higher proficiency permits learners to produce more complex syntactic structures. However, the majority of previous studies have focused on writing, almost exclusively with adult second language (L2) learners. Given the…

Little is known about the effects of different instructional approaches on learner affect in oral interaction in the foreign language classroom. In a randomized experiment with Dutch pre-vocational learners (N = 147), we evaluated the effects of 3 newly developed instructional programs for English as a foreign language (EFL). These programs…

This study reveals hitherto overlooked effects of age of onset (AO) in immersive school contexts, using multiple measures over time so as to focus on fluctuations and trends in individual data. The second language (L2) English development was studied in 91 children who received 50-50 content and language integrated learning (CLIL) instruction in…

With use of self-assessment (SA) of young language learners on the rise, educators of young learners often want to know what SA captures and how best to use it in order to assist their students' learning. This study focuses on understanding how young learners' processes for responding to SA items differ by age and by context of implementation…

Despite an increased awareness of language learner performance in task-based instruction, little is known about how learners perceive and respond to different task factors. This study investigates the effects of task complexity and modality on (a) learners' perception of task difficulty, skill, and its balance, and on (b) learners' task…

This study investigates the influence of the semantic heaviness of verbs (i.e., heavy or light verbs) and language proficiency on second language (L2) learners' use of constructional information in a sentence-sorting task and a corpus analysis. Previous studies employing a sentence-sorting task demonstrated that advanced L2 learners sorted English…

The current 2-part study investigated the relative contributions of English language training (ELT) and computerized Cogmed working memory training (WMT) to improvements in English-as-a-foreign language (EFL) proficiency and working memory capacity. In Study 1, Japanese undergraduate EFL learners were randomly allocated to 1 of 3 experimental…

Working with Korean university-level learners of English, this study provides a detailed analytical comparison of 2 task work groups that were video-recorded, with 1 group scoring very high and the other relatively low based on the results of a Group Work Dynamic (GWD) measuring instrument. Adopting a complexity theory (CT) perspective and…
