A new error protection assignment scheme with applications to real-time wireless multimedia transmission is presented. The proposed scheme exploits the structure of scalable sources to ensure optimal assignment. This novel approach recasts the nonlinear optimization problem into a linear one, and then further remodels it into a discrete programming problem, thereby reducing the computational co...

The purpose of this paper is to review several studies on the effects language aptitude recast-driven acquisition L2 morphosyntax. Recasts are one most commonly used forms corrective feedback in second (L2) classrooms. It clear from research that there a variety internal and external factors affect ability learners benefit recasting. Among those factors, working memory analytic ability, as two ...

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...

Among the major issues raised by classroom SLA researchers is the debate on the degree to which teacher’s or learner’s attention should be directed to linguistic features. However, one of the relevant variables in corrective feedback studies which seem to be less operationalized is the differential impact of different types of feedback on the accuracy of the oral performance of the participants...

Recent action selection architectures ly on planning, reaction, orboth, ignoring the wide spectrum of architectures inbetween. This paper recasts the action selection problem in terms of projection, commitment, and abstraction.

The current study examined the provision of corrective feedback and learner repair following feedback in the interactional context of child-to-child conversations, particularly computer mediated, in an elementary Spanish immersion class. The relationship among error types, feedback types, and immediate learner repair were also examined. A total of 46, fifth-grade children participated in the st...
