Domestic immersion (DI) is an effective context for postsecondary language learning, given that DI's instructor-curated environments promote meaningful second language use while providing abundant support for learners. However, DI is at present understudied within second language acquisition research, especially when compared to its more…

Defined as a combination of perseverance and passion for long-term goals, grit has been hypothesized to be as important as talent in determining the success of students, adding incremental predictive validity for achievement criteria above and beyond natural or inherent ability. In this study, we tested this hypothesis by comparing the effects of…

Although English and German are both Germanic languages, due to various historical changes, many of their cognates are no longer easily recognizable. This study examined whether knowledge of language history can be beneficial to learners when learning English-German cognates. Thirty-five English-speaking second language (L2) learners of…

The rationale behind this special issue is to underscore the importance of studying instructional materials in context--that is, how materials and textbooks are used by teachers and learners. Research on teaching materials needs to reach beyond traditional 'armchair' analyses and evaluations to appreciate the place of instructional materials in…

Willingness to communicate (WTC) is an important individual learner difference that can help account for varying rates of language-learning success across individuals. As learner talk is considered to be a key pedagogical activity, instructors and researchers often strive to identify and manipulate key variables that will increase and arouse a…

Motivational interactions during multiple language learning have been largely neglected in language motivation research. To fill this gap, we investigate longitudinal relations between Swiss German students' value beliefs in English, French, and German in upper secondary schools and whether there are differences in motivational development between…

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 investigates how visual context influences second language (L2) long-term structural priming for the Chinese "ba" construction. The experiment consisted of a baseline phase, an exposure phase, an immediate posttest, and a delayed posttest. L2 Chinese learners (N = 120) were assigned to 1 of 4 groups for the exposure…

Cognitive psychology research has shown that interleaving, wherein learners practice multiple skills or concepts at once, facilitates learning more than does blocking, wherein learners practice only one skill or concept at a time. Despite the advantage of interleaving over blocking observed across a number of domains, limited attention has been…

While an elicited imitation test (EIT) has been widely used as a measure of oral proficiency in second language acquisition (SLA) research, it is still unclear the extent to which memory capacity impacts EIT performance. In light of this gap, the present study sought to clarify the nature of elicited imitation by examining the relative…

This article reports the results of the first longitudinal study that systematically investigates the acquisition of verb agreement by hearing learners of a sign language. During a 2-year period, 14 novel learners of Sign Language of the Netherlands (NGT) with a spoken language background performed an elicitation task 15 times. Seven deaf native…

This study compares the effects of distributed versus massed corrective feedback (CF) on Spanish differential object marking (DOM). Forty-eight Spanish learners completed three communicative tasks with a researcher on three consecutive days, one task per day. Partial recasts were used to reformulate DOM errors. The distributed group (n = 16)…

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…

The emerging interest in grit, referred to as sustained perseverance and passion for reaching long-term goals and conceptualized as a facet of conscientiousness, has shown that language-specific grit is positively linked to foreign language (FL) achievement. Evidence from recent studies on intended effort and academic buoyancy--constructs…

This study proposed a set of measures for assessing noun phrase (NP) complexity in second language (L2) Chinese writing and compared the predictive power of these measures for L2 Chinese writing quality to that of a set of syntactic complexity measures based on the topic-comment unit (TC-unit). Our data consisted of 101 narratives written by…
