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.…

This study advances previous research about the effects of explicit instruction on second language (L2) development by examining learners' use of verbal morphology following different types of explicit information (EI) and comprehension practice. We investigated the extent to which additional EI about the first language (L1) can reduce the effects…

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…

Linguistic complexity serves as an important measure of second language (L2) writing development. Complexity indices, however, rarely feature in the studies of learner languages other than English. Additionally, L2 writing studies have been criticized for the lack of consistency in defining proficiency. The current study addresses these gaps by…

Language teachers are expected to engage in classroom assessment practices and report on learners' progress aligned with proficiency standards, as well as prepare learners for external examinations. The term "language assessment literacy" (LAL) describes what the constituency of language instructors needs to know about assessment…

The question of cognition in second language (L2) acquisition later in life is of importance inasmuch as L2 learning is largely mediated by domain-general cognitive capacities. While a number of these capacities have been shown to decline with age, individual differences in cognition increase over the lifespan. This microdevelopment study…

This study examines first language (L1) English transfer in the acquisition of plural noun semantics in second language (L2) Arabic. Drawing on previous research on the L2 acquisition of plural noun interpretation, the study presents and discusses new production data of specific and generic definite plurals by English-speaking learners of Arabic…

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…

Applied linguists have been exploring approaches to second language acquisition and competence that move beyond a prioritization of cognition and grammar that was derived from the foundational structuralist legacy in linguistics. Recently, for example, they have collaborated in putting together an integrated alternative model (Douglas Fir Group,…

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 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…

This article reports on an experimental study addressing the second language acquisition of Mandarin temporality. Mandarin Chinese does not mark past, present, or future with dedicated morphemes; the native English of the learners does. It was hypothesized that, in their comprehension, learners would utilize the deictic pattern of expressing…

This study explores the effects of various motivational variables operating within 44 English classes on 1-year-long gains in the English reading proficiency of 1,149 Japanese university students. The study adds new knowledge to the recent outcomes of second language (L2) motivational studies in 3 major ways. First, the explanatory variables…

Written corrective feedback has been subject to increasing attention in recent years, in part because of the conceptual controversy surrounding it and in part because of its ubiquitous practice. This study takes a meta-analytic approach to synthesizing extant empirical research, including 21 primary studies. Guiding the analysis are two questions:…

One of the central considerations in the validity argument for the TOEFL iBT is the relationship between the language on the exam and the language required for university courses. Corpus linguistics has recently been shown to be an effective way to explore this relationship, which can also be considered as an aspect of authenticity. Applying…
