In this paper, we describe the development of a Web bulletin board system and its implementation and evaluation in school mathematics classes. In our dynamic studies of Web-collaborative learning during the past few years, we have found that problems with such computerized systems lie in their inability to show how notes relate to each other through links. To solve this problem, we developed a Web bulletin board system enhanced by a knowledge map. The system is called NakSun. Using NakSun, learners can determine the coordinates, or location, of a node that has been entered. They also can link notes together in the windows. Moreover, they can enlarge any area they select on the screen, and they can reflect on the discussion's progress using the playback function. NakSun was implemented in mathematics classes in a few junior high schools in Japan three times to the same students. As a consequence, students gradually became oriented to the notes, which motivated them to master their assignments. They began to discuss and solve their mathematics problems eagerly and actively once they had become comfortable with the knowledge map and had grasped the meaning of linking notes. That is, although the knowledge map is comparatively effective in collaborative learning, our results indicated that it is essential that students obtain sufficient experience in using the system. Furthermore, our results of great interest made it clear that displaying all notes in sequential order is also essential for learners to take a glance at the many ideas and views.
