This paper investigated how production task combined with teacher feedback (in the form of recasts) affects child second language development, and effects complexity on their performance. 92 learners English in three intact classes were assigned to tasks different (simple, +complex, ++complex). In response errors use present third person singular verb forms, participants received recasts. L2 de...

The amount and states of water in a polymer electrolyte significantly affect the material's morphology as well its mechanical transport properties, thus determine performance many important applications such fuel cells, electrolyzers, other electrochemical energy conversion devices. In this study, recast H+-Nafion® films were characterized using attenuated total internal reflection FTIR (ATR-FT...

OBJECTIVE To evaluate the effects of recasting on the biocompatibility of a commercially available Ni-Cr alloy. METHODS The alloy tested was cast and subsequently recast four more times. For each cast condition, 24 disk shaped specimens were fabricated (5 mm in diameter, 0.5 mm in thickness). All the recasting was performed without adding new alloy. After the first cast and following each rec...

Based on the controversial beliefs among L2 teachers about effective corrective feedback (CF) strategies, recast and prompts as 2 kinds of CF have drawn the attention of L2 researchers(e.g., Braidi, 2002; Iwashita, 2003; Loewen & Philp, 2006; Panova & Lyster, 2002; Sheen, 2004). Despite these numbers of studies, debate continues to exist about their usefulness as a CF technique. Whereas recasts...

This study investigated the possible relationship between educational context and English Language Teaching (ELT) teachers’ corrective feedback preference. To this end, 42 Iranian EEFL teachers from some private language institutes and 39 Iranian EFL teachers from different schools in Shiraz, Iran participated in the study. The Questionnaire for Corrective Feedback Approaches (QCFAs) was ...

recent interaction studies havefocused on the relationship between interactional feedback and l2 development.despite the large body of knowledge in this regard, few studies have examinedlearners’ preferences for interactional feedback. besides, different findingshave been reported concerning learners’ preferences for feedback and none hasexamined the factors accounting for the variation in the ...
