The provision of corrective feedback in a spoken dialogue CALL system
نویسندگان
چکیده
In this paper we report on the development of a spoken dialogue system for computer aided language learning (CALL), and explore some of the issues involved in the incorporation of a corrective feedback module. We initially developed a small prototype system, and tested it for usability with visiting students of English as a foreign language. In the light of the positive results we obtained for this, we began to develop a more advanced system, with the aim of investigating how spoken dialogue systems might best be tailored to help language learning. The issue we focussed on was the kind of feedback on errors which might be most useful to the learner. We show the types of feedback we have considered, and highlight some of the problems associated with providing different types of feedback.

While some researchers have questioned the efficacy of corrective feedback (CF), other researchers believe that CF can be effective if implemented through new technology types, including e-portfolio (EP). However, whether EP can be used as a medium of providing CF for language learners at different levels of language proficiency is still unknown. The purpose of the present study, therefore, was...

متن کاملCorrective Feedback in Dialogue-based Computer Assisted Language Learning
Computer assisted language learning (CALL) systems are used by people to learn a language. CALL systems have provided a number of advantages for language learning such as their ability to provide consistent and flexible corrective feedback during the learning process. This feedback is expressed as information about what is ungrammatical or unacceptable in a target language. This paper presents ...
