A classroom study was designed to test the hypothesis that explicit knowledge is used by second-language (L2) learners in a free written response task if that knowledge is present. Eighty-one 12-18-year-old learners of Dutch as an L2 took part in a computer-assisted language learning experiment receiving either explicit or implicit instruction…

We studied how Dutch children learned English as a second language (L2) in the classroom. Learners at different levels of L2 proficiency recognized words under different task conditions. Beginning learners in primary school (fifth and sixth grades) and more advanced learners in secondary school (seventh and ninth grades) made lexical decisions on…

In most post-secondary Spanish language programs in the U.S., heritage language (HL) learners and second-language (L2) learners are enrolled together, in the same courses (Ingold, Rivers, Tesser, & Ashby, 2002). Nevertheless, there is scant empirical research on what actually goes on in these classrooms and what the nature of learner-learner…

This paper reports on an instructed second language acquisition study that investigated the effects of explicit phonetic instruction on second language pronunciation by adopting two different outcome measurements (i.e. a rubric of accentedness as well as comprehensibility). Twenty native Japanese learners of English in ESL (English as a second…

The purpose of this study is to analyse the effect of metalinguistic instruction on students' metalinguistic knowledge on the one hand, and on students' performance in metalinguistic and oral production tasks on the other hand. Two groups of primary school students learning English as a foreign language were chosen. One of them (Rule group) was…

The optional use of morphology attested in second language learners has been attributed either to a representational deficit or to a "surface" problem with respect to the realization of inflectional affixes. In this article we contribute to this issue by providing empirical data from the early interlanguage of Greek learners of Turkish. Three…

This chapter presents the results of a study on interlanguage variation. The production of four L2 learners of Italian, tested four times at yearly intervals while engaged in four oral tasks, is compared to that of two native speakers, and analysed with quantitative CAF measures. Thus, time, task type, nativeness, as well as group vs. individual…

With the increasing use of integrated tasks in assessing writing, more and more research studies have been conducted to examine the construct validity of such tasks. Previous studies have largely focused on reading-writing tasks, while relatively little is known about graph-writing tasks. This study examines second language (L2) writers'…

This study investigates dominant language transfer (from English) in adult Spanish second language (L2) learners and Spanish heritage speakers. We focus on contrasting properties of English and Spanish definite articles with respect to generic reference ("Elephants have ivory tusks" vs. "Los elefantes tienen colmillos de marfil") and inalienable…

This exploratory qualitative case study reports the impact of using a public-speaking structure (Powerful Oral Language Lab [POLL]) in teaching preservice Chilean English pedagogy students. It describes how this task-based method of English as a Foreign Language (EFL) teacher training is related to language strategic competence. Twenty students…

This volume brings together theoretical perspectives and empirical studies in second language (L2) acquisition and bilingualism and discusses their implications for L2 pedagogy. The book is organized into three sections that focus on prominent linguistic and cognitive theories and together provide a compelling set of state-of-the-art works. Part I…

This study compares Spanish morphosyntax error types and magnitude in monolingual Spanish and Spanish-English bilingual children with typical language development (TD) and language impairment (LI). Performance across groups was compared using cloze tasks that targeted articles, clitics, subjunctives, and derivational morphemes in 57 children.…

The present study investigated the effects of two categories of interactional feedback--recasts and elicitations--on learning linguistic forms that arose incidentally in dyadic interaction. The study also identified implicit and explicit forms of each feedback type and examined their subsequent effects immediately after interaction and after 2…

Previous language learning research reveals that the statistical properties of the input offer sufficient information to allow listeners to segment words from fluent speech in an artificial language. The current pair of studies uses a natural language to test the ecological validity of these findings and to determine whether a listener's language…

This study examines the relationship between learners' production of modified output and their working memory (WM) capacity. The task-based interactions of 42 college-level, native English-speaking learners of Spanish as a foreign language were examined. A relationship was found between learners' WM test scores and their tendency to modify output.…
