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 study explored the impact of metacognitive instruction provided in conjunction with corrective feedback, investigating the moderating effects of two types of implicit corrective feedback (input-providing conversational recasts vs. output-prompting clarification requests) that targeted English third-person singular "-s" and…

This study investigated the relative effectiveness of two instructional interventions (implicit and explicit feedback) as a function of implicit sequence-learning ability. Second language (L2) attainment was measured by means of a self-paced reading task, which shows online sensitivity to language errors. Implicit sequence-learning ability was…

This study investigated the effects of teaching English prepositions using schematic diagrams inspired by cognitive linguistics in a computer-based tutorial system called the English Preposition Tutor. Training was designed based on the theoretical framework of the Competition Model and a cognitive linguistic analysis of prepositions. Sixty-four…

The study compared the effects of two types of form-focused written feedback--direct corrective feedback (DCF) and metalinguistic explanation (ME) given to the whole class--on Japanese university students' accuracy of use of two grammatical structures: indefinite article and the hypothetical conditional. Both types of feedback were given with…

This study investigated the effect of direct and indirect comprehensive corrective feedback (CF) on second language (L2) learners' written accuracy (N = 268). The study set out to explore the value of CF as a revising tool as well as its capacity to support long-term accuracy development. In addition, we tested Truscott's (e.g., 2001, 2007) claims…

This study investigated the effects of negative feedback type (i.e., explicit correction vs. recasts), communication mode (i.e., face-to-face communication vs. synchronous computer-mediated communication), and target structure salience (i.e., salient vs. nonsalient) on the acquisition of two Turkish morphemes. Forty-eight native speakers of…

Sixty-five Japanese learners of English participated in the current study, which investigated the acquisitional value of form-focused instruction (FFI) with and without corrective feedback (CF) on learners' pronunciation development. All students received a 4-hr FFI treatment designed to encourage them to notice and practice the target feature of…

This study reports on a meta-analysis on the effectiveness of corrective feedback in second language acquisition. By establishing a different set of inclusion/exclusion criteria than previous meta-analyses and performing a series of methodological moves, it is intended to be an update and complement to previous meta-analyses. Altogether 33 primary…

Input exposure is essential for nonprimary language learning, but the importance of explicit instruction and corrective feedback continues to be debated. If instruction is required, how might it be optimized in terms of its nature and timing? In this study, 65 Spanish-English bilinguals were introduced to Latin through an interactive computer…
