This study explored the effects of practice schedule on the processing of new second language (L2) vocabulary and resulting knowledge. Participants were 107 low-achieving adolescents attending a vocational high school in Korea. They were randomly assigned to one of three practice groups and completed a L2 English-L1 Korean paired-associates…

This study examines learner deliberations over their discursive plans during second language (L2) instructional tasks, which we call "intersubjectivity negotiation episodes" (INEs). We argue that these provide essential contexts for negotiations over L2 form-meaning mappings, known as "language related episodes" (LREs). Our…

This study demonstrates how conversation analysis can illuminate the interactional practices through which the Present-Attention-Co-construction-Extension (PACE) approach to grammar instruction, which involves a guided, inductive co-construction of grammar rules with learners, is realized in the classroom. The data consist of three whole-class…

We conducted a multisite replication of Yang and Lyster's (2010) study investigating the effects of recasts and prompts on learning English regular and irregular past tense. Our study was conducted with intact high school and vocational school classes in Italy and Bosnia. Our participants were young adolescents (14-15 and 16-17 years old), a…

This article focuses on the role of crosslinguistic patterns with verbs in the mapping of noun phrases/semantic roles to positions in morphosyntax, with a particular focus on second language (L2) development of Spanish "se." The data set derives from high school learners of Spanish in the United States under broadly deductive and…

The interactionist hypothesis holds that conversational interaction facilitates second language (L2) learning by providing learners opportunities to receive meaningful input, modify their output, and attend to language form. Although research has often explored the efficacy of different types of L2 instruction (deductive or inductive), few studies…

This study employed a multisite design to investigate the differential impact of deductive and guided inductive instruction for second language (L2) grammar development in ecologically valid classroom contexts. Students (n = 138) from eight intact third-year L2 Spanish classes in three public high schools in the United States received deductive…

This study investigated classroom interaction through the framework of "stancetaking" (Du Bois, 2007) to understand how Spanish second language (L2) learners positioned themselves when participating in communicative language learning activities. Data came from transcribed audio and video recordings of three 90-minute lessons in one…

Answering calls to map college-level proficiency development (Modern Language Association, 2007) and longitudinally chart language learning (Barkaoui, 2014; Ortega & Byrnes, 2008), we mapped the oral proficiency growth of 1,922 lower-division college students of Chinese, French, Russian, and Spanish (in the second, third, or fourth semester of…

This 8-year longitudinal case study of Fabiola, a Spanish-English bilingual, investigated her argumentative writing development, focusing on her use of evidence to support and develop arguments over time from high school through university. Data sources included 36 writing samples. Texts across grade levels and course types were analyzed to…

This classroom-based study explored links among second language (L2) learners' interaction mindsets, interactional behaviors, and L2 development in the context of peer interaction. While peer interaction research has revealed that certain interactional behaviors (e.g., receiving corrective feedback and engaging in collaborative interaction) assist…

This descriptive observational study aimed at exploring the form-focused instruction (FFI) interventions used by four French and four English as-a-second-language high school teachers to draw their students' attention to form. With the help of an Intervention-on-Form(s)-Observation Scheme (IFOS) developed and tested for this purpose, each FFI…

The Foreign Language Classroom Anxiety Scale (FLCAS) has been challenged on the grounds that it may also assess language learning skills. In this study, 128 students who had been administered measures of first language (L1) skills in elementary school were followed from 1st to 10th grade. Fifty-three students had completed second language (L2)…

The study examined whether individual differences in high school first language (L1) reading achievement and print exposure would account for unique variance in second language (L2) written (word decoding, spelling, writing, reading comprehension) and oral (listening/speaking) proficiency after adjusting for the effects of early L1 literacy and…

The acquisition of English verbal morphology has been mostly tested as a second language (L2) in English-speaking settings (Bardovi-Harlig, 1992a, 1992b, 1992c, 1998; Bardovi-Harlig & Bergstrom, 1996; Bayley, 1991, 1994), more rarely as a foreign language (e.g., Robison, 1990, 1995), in only one cross-sectional study with native speakers of French…
