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...
Abstract This study examined the effect of two types of feedback, post-text as a written feedback and recast as an oral one on written grammatical accuracy of Iranian intermediate EFL learners. To this end, 45 intermediate students who were studying at Ideal Language Institute in Sari were selected based on their performance on the Nelson proficiency test, and then divided into three groups (tw...
the research was aimed at finding out the effects of the implementation of writing feedback techniques and students’ writing anxiety on students’ writing ablity. experimental method of 3x2 factorial design was employed in the research. there were three experimental groups of students who were taught by using teacher feedback, peer feedback and the combination of peer and teacher feedback writin...
abstract tasks nowadays are at the center of attention in sla research. task types is one of the critical issues in this regard, their effectiveness and suitability to any particular context, their characteristics and the result they yield are among some of these issues. on the other hand, discourse markers (dms) have been very much investigated and their effectiveness in conveying the meaning...
In this work, we consider the problem of boundary stabilization for a quasilinear 2 × 2 system of first-order hyperbolic PDEs. We design a new full-state feedback control law, with actuation on only one end of the domain, which achieves H2 exponential stability of the closedloop system. Our proof uses a backstepping transformation to find new variables for which a strict Lyapunov function can b...
this research chiefly focused on the application of mitigation strategies and traditional form of feedback in writing development of the fifth semester university students majoring in tefl and english translation fields based on vygotsky’s sociocultural theory in general and the notion of “zone of proximal development” in particular. to that end, this study relied on a pre-posttest experimental...
One skill that student teachers need to develop during their academic studies is the capacity to produce accurate and well-organized texts. This study reports on the comparative impact of metalinguistic feedback (MLF), teacher interactive feedback (TIF(, and the peer-feedback (PF) on the accuracy and organization of postgraduate ELT student teachers’ writing. The participants were 57 postgradua...
We consider optimal dynamic multidrug therapies for human immunodeficiency virus(HIV) type 1 infection. We describe an optimal tracking problem attempting to move the state of the system from an “unhealthy” state (high virus load and low immune response) to a “healthy” one (with low viral load and high immune effector levels). We consider feedback control with full state as well as with partial...
time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. the stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. it is well-known that the stabi...
