Abstract: Abstract Instant messenger (chat) Computer-Supported Collaborative Learning (CSCL) chat is one of the most important tools which can be used effectively for Computer-Supported Collaborative Learning (CSCL) because it is possible to share and exchange thoughts between learners and teachers, and build collaboratively knowledge. Furthermore, its main role in the application is that of information transferring and interaction between participations in CSCL environment in order for a chat to become one of the most important applied software which is meant for educational purposes. Also, it is a real representation of virtual classes which are designed by information technology, because of the properties of the CSCL chats with their interactive tools, connection tools and a number of participants and it depends on synchronized connection regardless of the participants’ places. On the other hand, the chats can be with written text, spoken or video chats. Moreover, one of the advantages of CSCL chats is the control of educational inputs such as the educational material and the presentation of argumentative questions and illustrative examples, in addition to the possibility of using established educational tools to make educational material simpler or explain examples as (multimedia or web pages), and this is similar to educational dialogues in traditional learning, but CSCL chats are more exciting and interactive for participants. Although CSCL chats have many advantages, they also face many challenges. One of them is that there are almost no supportive technical mechanisms able to analyze chats to assess individual and collaborative participations, in addition to the difficulty of recognizing the threads discussed, and this is one of the most important reasons that impede officially the use of CSCL chats in education, because of the inability to assess learners’ dialogue. Also, there is no feedback from the teachers to be able to assess students’ participation, the learners needing to know the extent of their participation in the educational discussion. The manual assessment of the discussion participation in the chat could be difficult or impossible even because of the huge amount of mutual information. This thesis presents a system that is assumed to enable teachers in assessing chats automatically. It also shows the results obtained from the analysis in the form of statistics and graphics. Moreover, the proposed model in the thesis is based on assessing individual participations through identifying the most important threads, discussed by each participant in the chat, relying on Mikhail Bakhtin’s dialogism theory and Trausan-Matu’s polyphonic model. As to the collaborative assessment, the model used an effective way to find associative relationships among the important threads discussed by students, the Rhetorical Structures. Accordingly, the collaboration is represented in the form of associative relationships resulting from linking cue phrases (“and”, “or”, “but”, etc.) between the participants' contributions with each other, which represent the important threads in the chat. Then, the collaboration is assessed by studying the relations resulted from linking the important threads using cue phrases. In addition, it is analyzed the content of the chat considering the altruistic dimension and, its reverse, selfishness. Accordingly, the inferred altruistic dimension of the conversation is computed by the ratio of the number of utterances referring to the threads of the other students and the number of utterances a student is referring to its own thread. The altruistic dimension helps teachers and students assess the success of the achievement of the dialogue of the educational group. This would be reflected on how students manage their discussions away from hooking to their own ideas and knowing the extent to which students accept the ideas and opinions of others, in addition to achieving the main goal of collaborative learning and in unifying ideas to reach valuable information that helps in raising the level of teamwork.
