This paper is designed to propose a theoretical model of collaborative learning in simultaneous second languageacquisition. In order to achieve the model, we created a video chat system named BiTak, which employs strict turn-takingdual-lingual communication using recording function. BiTak aims to motivate the dual-lingual conversation between secondlanguage learners as well as to identify the mutual benefits through this kind of conversation for the need of improvingsimultaneous bilingual acquisition. We conducted experiments to evaluate the effectiveness of BiTak as well as the collaborationof learners through using it, and found that the system brings about the sense of language learning and favorably boost students’speaking skills. The learners unintentionally take roles in helping each other practicing second language as facilitators andreceivers.
