Lecture Notes in Computer Science- P89: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 | Design on Collaborative Virtual Learning Community 429 asynchronous communication. Besides virtual learning community refers to the concept of visual process chart VPC so that it can visualize the learning process. Visual Process Chart VPC VPC as a chart tool can display the learning process of group member or between the group members. According to the collaborative learning factors of affecting learner s learning involve group s division participation of group members task distribution and teachers help in time progress test and so on. The paper illustrates one of the factors named the participation of group members to design VPC. The measure of learning participation contains learner s sending message replying message looking message neglecting other factors. Each group members contribute to their group s online communication in certain message. In VPC red circle presents group member while grey circle presents a group 10 . The same group agglomerates together with dashed Circle. As shows in figure 4 it is assigned into 3 groups in a class. Fig. 4. Screenshot of the VPC For example observing the encircled part we can see there are four red circles which stand for group members and one grey circle which presents a group. They are around the group tightly. In VPC the distance between circle and group circle named line segment LS points out the length of sending message. We called information content IC for short. If a circle is near the group then its IC is more compared to far away. Circle s diameter implies the quantity of a learner s average message we called it information degree ID for short. If a circle is smaller it means the message quantity is less compared to those bigger ones. According to this we can know the group circle in the same way. If the grey circle is bigger in other word the diameter of which is longer the ID is bigger compared to the smaller one. If LS between group and class is longer the information content is less. Therefore students
