A Dual-Role Collaborative Learning Support System for Simultaneous Speaking Acquisition in English and Japanese

Learning a foreign language is becoming more vital in Japan as a result of globalization. It gives foreigners various reasons to study Japanese including working or living in Japan. They should exchange language and skills and generate opportunities for engagement. Assisting them in exchanging linguistic skills and knowledge is critical. This study first proposes a theoretical model of dual-role collaborative learning to improve second language learners' speaking skills. Learners will participate as facilitators in their native language and receivers in their second language. Some supporting features must be given, followed by a Computer-supported Collaborative Learning (CSCL) named BiTak which is a video chat system that allows strict turn-taking dual-lingual conversation. The learner’s progress is positively evaluated by language teachers using a Rubric scoring framework. Based on the experiment results, it was concluded that BiTak has turned users' perspectives of video chat programs into collaborative learning platforms, allowing them to act as facilitators and receivers.
