Designing a Scaffolding-based CALL System with corrective feedback

Abstract

With the development of the technology today, more advanced and powerful Computer Assisted Language Learning (CALL) systems are applied into language learning classroom to help students acquire English ability. However, several surveys show that some CALL systems are lack of theory-based and corrective feedback to meet pedagogical requirement and indicate learners’ language faults. Thus, this paper presents a theory- based student-centered CALL system to support elementary school students learning English. The framework contains four parts elements and it is developed based on the scaffolding theory. The learning activities are set as main-scaffolding to support step by step individual learning and the corrective feedbacks are set as sub-scaffolding to give learners detail explanation of how to correct their language faults.
