abstract the extent to which teachers’ written corrective feedback (wcf) is conducive to esl learners’ improvement has been discussed since truscott’s claim in 1996. the mentioned debate continues because there has been lots of contrastive research studies with different results. this paper presents the results of a 2-month study of the effectiveness of wcf to 65 low intermediate iranian learne...

This study addresses the impact of 2 types of written corrective feedback (WCF) on the acquisition of the third person singular -s in English. The study followed a quasi-experimental design: 2 experimental groups and 1 control group that included 57 preservice teachers from a Chilean university. The experimental groups underwent a treatment based on the provision of direct metalinguistic feedba...

Direct manipulation, which is the dominating “interaction style” for mobile computers, fails to meet the conditions of many mobile use situations. In particular, it demands too much visual attention of the user. We introduce a new, complementing interaction style (and system) for mobile computers, called MOTILE, which addresses three main requirements of interaction with mobile computers: (1) n...

background: morning report sessions had long-standing history in medical education. morning report management is an important aspect of professional medical education. methods: to evaluate the contents of the morning report sessions, including management, staff training, deep learning, attention to learners at different level of education, record keeping, feedback, and final summarizing, direct...

The present study explores the effect of providing different types of written corrective feedback (WCF) on 79 Iranian EFL learners’ writings over time through a pre-test, immediate post-test and delayed post-test. In this way, the study first aims to investigate the extent to which different types of WCF result in improved accuracy in writing over a period of two months, and then maintain...

The present study attempts to uncover language teachers’ beliefs about oral corrective feedback. It also explores the role of teachers’ experiences in their choice of error correction techniques. To achieve the purpose of the study, 137 foreign language teachers were asked to fill out the developed questionnaire and follow-up interviewed were conducted with 10 teachers, five novice and experien...

A loudspeaker feedback system is built in this project. A class D switching amplifier and the loudspeaker are placed in a closed loop. The switching power amplifier is a simple pulse width modulator, but without the conventional output filter that is made up of expensive inductors and capacitors. The band-pass loudspeaker replaces the output filter. Feedback is achieved by an electret condenser...

We propose an approach for the direct design from data of controllers finalized at solving tracking problems for nonlinear systems. This approach, called Direct FeedbacK (DFK) design, overcomes relevant problems typical of the standard design methods, such as modeling errors, nontrivial parameter identification, non-convex optimization, and difficulty in nonlinear control design. Considering a ...
