36 Recent studies have highlighted the modulation and control of feedback gains as support 37 for optimal feedback control. While many experiments contrast feedback gains across 38 different environments, only a few have demonstrated the appropriate modulation of 39 feedback gains from one movement to the next. Here we extend previous work by 40 examining whether different visuomotor feedback g...

INTRODUCTION Medical students at the Faculty of Medicine, University of Geneva, Switzerland, have the opportunity to practice clinical skills with simulated patients during formative sessions in preparation for clerkships. These sessions are given in two formats: 1) direct observation of an encounter followed by verbal feedback (direct feedback) and 2) subsequent review of the videotaped encoun...

This study investigated the effects of two types of written feedback – direct corrective feedback (DCF) and metalinguistic explanation (ME) - on Iranian EFL learners’ implicit and explicit knowledge of English definite and indefinite articles. Assigned to three groups of DCF, ME, and control groups, the participants took four tests in three testing phases: pretest, posttest, and delayed posttes...

An effective wide band active control law through one kind of the Dynamic Vibration Absorber (DVA) is proposed and studied in this paper. With the help of mechanical impedance method, active DVA control law is formulated based on the passive mechanical model. The electrical DVA can generate multi-mode active damping to the structure. The host structure is an aluminum plate and acceleration sign...

this study is a typological description of written formative feedback in an efl context in iran. twenty m.a. students of tefl participated in the study. they were required to summarize a scholarly article in each session on which the instructor would provide written corrective feedback (cf). written formative comments were extracted, coded, and categorized into various types, such as asking for...

The present study aims to trace the long term effects of different types of feedback--direct, indirect, and content-on EFL learners' writing accuracy (the major concern of SLA researchers) and overall writing quality (the primary aim of L2 writing researchers). Data was gathered from three groups of Iranian EFL learners (N=44) randomly assigned to an indirect feedback, a direct feedback, and a ...
