Lecture Notes in Computer Science- P39:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers | Collaborative Learning Tool Applying to C Programming Language 179 the effectiveness of collaborative learning 4 5 and 6 . During the collaborative learning process all teammates will benefit from each other 7 . The approach to education that is more suitable to the educational environment through group collaborative learning. In this paper we introduce the system architecture which we have developed that include audio and text information communication to support co-operation and teamwork and it has program co-editor interface 8 . The rest of this paper is organized as follows Section 2 presents related work about our research. Section 3 introduces the main research of the system architecture implementation. Section 4 we will discuss with the difference of other collaborative software and our tool. Section 5 concludes this paper and discusses the future works. 2 Related Work In this section we are going to introduce the related work about this paper. First we will present the theoretical background about collaborative learning. Collaboration defined working together to complete the shared goals 9 . Collaborative learning allows students to share their knowledge and information each other within the problem-solving process 10 . Second we present the ways of teaching learning C programming language. At last we will talk about the theoretical foundations of VoIP the technology we use in our system. Collaborative Learning Studies have shown that collaborative learning procedures have proved to be more effective than traditional instructional methods for student s learning and academic achievement process. It also improves participants satisfaction with the learning 4 11 . Learning is sharing and more shared that is more learned. It is even supposed that students are learning as much from each other as from teaching material of course or from the teacher in the class. In America the studies have also presented that students who usually use the collaborative .
