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...

This study seeks to investigate the effect of explicit and implicit corrective feedback on the narrative writing of advanced Iranian EFL learners.

Usually writing teachers feel commitment to provide their learners with corrective feedback (CF) to their linguistic errors. The study investigated whether two types of written corrective feedback, indirect focused corrective feedback and indirect unfocused corrective feedback, produced differential effects on the accurate use of grammatical forms by high intermediate EFL learners. In this stud...

  This study investigated the effect of gender and type of written corrective feedback (WCF) on Iranian pre-intermediate EFL learners’ writing. Four intact classes were assigned to experimental and two intact classes to control groups. The learners were homogenized using a pre-test which was followed by sixteen sessions lasting one hour and forty five minutes. After receiving instruction on how...

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...
