Researchers and educators in the field of second language acquisition (SLA) have long been interested in the role of corrective feedback (CF) in language teaching and learning (Cohen, 1975, 2018; Ellis, Loewen, & Erlam, 2006). The main goal is to explore how to provide CF, the kind of feedback to provide, when, and by whom in order to…

This paper aims to describe a computer-assisted English learning system using chatbots and dialogue systems, which allow free conversation outside the topic without limiting the learner's flow of conversation. The evaluation was conducted by 20 experimenters. The performance of the system based on a free conversation by topic was measured by the…

Using errors as a method of learning has been made explicit through a two-staged peer review and discussion. During organic chemistry discussion sessions, quizzes are followed by a structured peer review designed to help students identify and discuss student errors. After the face-to-face discussion, a second stage of review involves analyzing and…

In this paper we present a system for automatic correction of errors made by learners of English. The system has two novel aspects. First, machine-learned classifiers trained on large amounts of native data and a very large language model are combined to optimize the precision of suggested corrections. Second, the user can access real-life web…

Synchronous Computer-mediated communication (CMC) creates affordable learning conditions to support both meaning-oriented communication and focus-on-form reflection that play an essential role in the development of language competence. This paper reports how corrective feedback was negotiated through expert-to-novice collaborative efforts and…

This paper describes a project involving EFL learners in synchronous electronic discussions. The output of the students' interactions was analyzed qualitatively to uncover the main linguistic and interactional features. It was observed that the students' discussions contained a large number of spelling, usage, and grammatical errors, an almost…
