Languaging--that is, using language to mediate thinking, orally or in writing--facilitates second language (L2) learning. As languaging requires the deliberate, analytical action of L2 learners, learners with higher language aptitude are likely to benefit more from languaging than those with lower aptitude. Thus, this study investigated the extent…

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…

As second language (L2) research adapts to the dynamics of multimodal instruction, researchers are exploring the role of captioning and textual enhancement (TE) on learner development. The present experiment assesses the differential effects of textually enhanced captions on learners' elicited imitation of L2 Spanish grammar. Twenty-eight…

This special issue contains reports of research on a variety of variables that are hypothesized to have an impact on how practice affects language learning. This includes spacing of practice opportunities, the provision of feedback, training working memory, and oral versus written input. Each study is complex and clearly contextualized within the…

This study draws on multimodal conversation analysis to emically account for moments in second language (L2) English interaction in which speakers appear to be visualizing text as they talk. One way they do this is by slotting out elements of a turn-in-progress in the air, shifting their hand in a slotting gesture from left to right as they say…

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…

We examined the role of modality in learning second language (L2) grammar and forming implicit (unconscious) and explicit (conscious) knowledge. To this end, we isolated the effects of the physical medium of input (i.e., aural or visual) from those of the presentation method (i.e., word-by-word or simultaneous). We also explored the role of test…

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…

The aim of this article is to show that the use of Spanish grammatical aspect is biased by inherent aspect depending on the learner's first language (L1). It considers both the Lexical Aspect Hypothesis (LAH; Andersen, 1986, and his followers) and the L1 Transfer Hypothesis (Izquierdo & Collins, 2008; McManus, 2015), and it compares the use of…

This study investigated the effects of extensive versus intensive recasts. The focus was on the effect of feedback on learning English articles, which, as nonsalient target structures, have been shown to be difficult for many second language learners. Intensive recasts were operationalized as recasts provided on article errors only, while…

This study launched an investigation into the extent to which textual enhancement in captions can promote learner attention to and subsequent development in second language (L2) grammar. Using eye-tracking, it also intended to extend research on the relationship between attention and L2 learning. A pretest-posttest experimental design was…

This empirical study investigated the occurrence of meaning negotiation in an interactive synchronous computer-mediated second language (L2) environment. Sixteen dyads (N = 32) consisting of nonnative speakers (NNSs) and native speakers (NSs) of English performed 2 different tasks using videoconferencing and written chat. The data were coded and…
