having in mind the high level of challenge in writing as a foreign language, this research provided iranian efl learners with audiovisual feedbacks as an alternative of common written feedback and focused on its’ meaningfulness in order to provide an incentive medium for the participants and increase their moti-vation. one hundred young adult female learners in addition to six english language ...

an enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. at first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. the advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...

in this paper we consider a petrovsky viscoelastic inverse source problem with memory term in the boundary condition. we obtain sufficient conditions on relaxation function and initial data for which the solutions of problem are asymptotically stable when the integral overdetermination tends to zero as time goes to infinity.

the present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in iranian efl setting. sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on nelson language proficiency test. then, their grammar ability was measured based ...

introduction: laser tissue soldering using albumin and indocyanine green dye (icg) is an effective technique utilized in various surgical procedures. the purpose of this study was to perform laser soldering of rat skin under a feedback control system and compare the results with those obtained using standard sutures. material and methods: skin incisions were made over eight rats’ dorsa, which w...

Research on written corrective feedback (WCF) has received sustained interest in the field of second language acquisition and education. This viewpoint article extends theoretical conceptual discussion WCF research by introducing notions “feedback literacy” ecology”. In this article, I first review three strands research. Then, argue for need to shift focus our investigation from information (f...

this research study aimed at investigating whether using peer-provided feedbacks rather than teacher-provided comments would result in any significance difference in iranian english undergraduate students’ ability in writing. in so doing, based on a pretest (an opt & a writing exam), 40 subjects were assigned to two homogeneous groups of equal number the subjects in the control group received m...

oral corrective feedback, according to many researchers’ points of view, plays a crucial role in facilitating and accelerating the process of the second language learning. the present study aims to identify persian learners’ error types, the teachers’ feedback types and learners’ uptakes; also it is aimed at determining the most and least frequent errors occurred on the basis of lyster and rant...

The main role and responsibility of second language writing teachers is to help learners to write with minimal errors. To do so, teachers need to provide students with appropriate types of feedback. In this research, the researchers examined the effect of post-text written corrective feedback on written grammatical accuracy of Iranian intermediate EFL learners. In the first phase, Nelson Profic...
