In the information and communication era, Computer-Supported Collaborative Learning (CSCL) is becoming prominent in higher education, and universities are gradually bringing argumentation in CSCL environments into the mainstream of their educational programs. The study proposed here is designed to identify the factors influencing ACSCL environments in order to promote the quality of the learning process and results. A comprehensive model for the factors influencing ACSCLearning is not yet available. So, the relevant literature has been reviewed to construct and develop a theoretical framework of factors which could influence the effectiveness of ACSCLearning. A preliminary model of ACSCL is proposed by identifying factors including student/peer, learning environment, learning processes and activities combined with possible sub-skills of argumentation thinking.
