Corrective feedback has received significant attention in English language teaching, and its role has been highly substantial. Considering the importance of corrective feedback in EFL classes, this study aimed at finding the effects of indirect and gradual CF on Iranian EFL learners' grammatical development and their beliefs toward CF. Twenty EFL learners, meeting the c...

an equitable risk allocation between contracting parties plays a vital role in enhancing the performance of the project. this research presents a new quantitative risk allocation approach by integrating fuzzy logic and bargaining game theory. owing to the imprecise and uncertain nature of players’ payoffs at different risk allocation strategies, fuzzy logic is implemented to determine the value...

This paper studies output feedback control of pure-feedback systems with immeasurable states and completely non-affine property. Since availability of all the states is usually impossible in the actual process, we assume that just the system output is measurable and the system states are not available. First, to estimate the immeasurable states a state observer is designed. Relatively fewer res...

We introduce a notion of complexity complex ℓ \ell -adic sheaves on quasi-projective variety and prove that the six operation...

While the importance of feedback to learning is well acknowledged in the pedagogical literature, the perceptions of multiple forms of feedback among learners is yet to attract significant attention, particularly in the IS context. Consequently, this research investigates the antecedent constituents of feedback and how they contribute to an overall perception of feedback in an introductory IS co...

the wisdom of crowds, an innovative theory described in social science, claims that the aggregate decisions made by a group will often be better than those of its individual members if the four fundamental criteria of this theory are satisfied. this theory used for in clustering problems. previous researches showed that this theory can significantly increase the stability and performance of lea...

The present study-both qualitative and quantitative--explored fifty EFL learners’ preferences for receiving error feedback on different grammatical units as well as their beliefs about teacher feedback strategies. The study also examined the effect of the students’ level of writing ability on their views about the importance of teacher feedback on different error types. Data was gathered throug...
