This research aims to assess the efficacy of electronic feedback (e-feedback) and traditional oral on undergraduate students’ English writing over 12 weeks teaching. Three treatment groups were involved: Asynchronous written e-feedback through Microsoft Word Track Changes; teacher–student metalinguistic conferencing; no control group. Two grammatical features (i.e., conjunctions articles), most...

Following the administration of a standardized language proficiency test (Preliminary English Test), sixty-two participants were selected and were randomly assigned to the control (direct-only correction) and experimental (direct meta...

A coupled system of two singularly perturbed linear reaction–diffusion two-point boundary value problems is examined. The leading term of each equation is multiplied by a small positive parameter, but these parameters may have different magnitudes. The solutions to the system have boundary layers that overlap and interact. The structure of these layers is analysed, and this leads to the constru...

Corrective feedback has received significant attention in English language teaching, and its role has been highly substantial. Considering the importance of corrective feedback in EFL classes, this study aimed at finding the effects of indirect and gradual CF on Iranian EFL learners' grammatical development and their beliefs toward CF.

This paper describes methods to recognize English utterances by Japanese learners as accurately as possible and detects grammatical errors from the transcription of the utterances. This method is a building block for the voice-interactive Computer-Assisted Language Learning (CALL) system that enables a learner to make conversation practice with a computer. A difficult point for development of s...
