The study examined how learners' motivational dispositions predict the complexity, accuracy, fluency of their oral task performance and their overall second language proficiency. Eighty-one speakers of English as a second language in the United States completed a regulatory focus and a regulatory mode questionnaire, an oral interview task, and a…

Background: Previous studies on language production in normal ageing have primarily focused on distinct dimensions of older adults' spoken language performance, such as fluency and complexity. However, little attention has been paid to the complex, interconnected relations between these dimensions. Additionally, older adults have been treated as a…

As integrated writing tasks in large-scale and classroom-based writing assessments have risen in popularity, research studies have increasingly concentrated on providing validity evidence. Given the fact that most of these studies focus on adult second language learners rather than younger ones, this study examined the relationship between written…

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking…

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…

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…

The present study was focused on acquisition of Chinese relative clauses (RCs) by second language (L2) learners and whether this acquisition was influenced by RC linguistic features, learners' Chinese proficiency levels, and their first language (L1). Data were gathered via a Chinese reading comprehension test, a grammaticality judgment task, a…

This study examines the influence of pre-departure proficiency on English as a second language (L2) oral development after a semester studying abroad in two distinct learning contexts. The data analysed were collected from tertiary level students (N = 33) who undertook an ERASMUS exchange semester in a European country where English was either the…

This study reports on how project-based language learning in which L1 Japanese EFL learners created short videos affected L2 oral proficiency. Students took short speaking tests before and after the class, and the fluency, complexity and accuracy of the pre- and posttests were measured to see which, if any, of these three aspects of proficiency…

Many studies that have investigated the educational value of online machine translation (MT) in second language (L2) writing generally report significant improvements after MT use, but no study as of yet has comprehensively analyzed the effectiveness of MT use in terms of various measures in syntactic complexity, accuracy, lexical complexity, and…

Second language (L2) writing has been determined to be influenced by what is read, with language learners tending to borrow words and short phrases from input texts while writing (e.g., Wang & Wang, 2015). This phenomenon is referred to as lexical alignment. Only one empirical study has investigated the influence that the linguistic complexity…

Research has painted a pessimistic picture of students' second language (L2) writing skills in secondary education. One innovative tool that may help students foster their L2 proficiency, including writing ability, is in-class debate. Debate is commonly associated with oral communication and argumentation skills. However, debate may also offer…

Investigating the effects of task design and implementation features on second language (L2) production is necessary, as the findings can provide potential insights into pedagogical and assessment task design and sequencing as well as into the nature of L2 learners' attentional resources. To this end, this study probed into the effects of task…

While there is ample evidence that study abroad (SA) enhances oral fluency in a foreign language, the effects of different types of learning context on other aspects of oral skills, such as vocabulary use, have not received much attention in academic research and are less clear. The present study tries to fill this void by investigating lexical…

This study determines the fine-grained bottom-up linguistic features involved in successful second language (L2) English academic group oral tutorial discussion through the use of a spoken learner corpus composed of more than 20 hrs of L2 production. Student performances were graded by teacher-raters using a can-do rating scale, which assessed…
