Web上の知識マップを用いた数学的問題解決とその過程の分析

抄録

Although collaborative learning using the Internet has been extensively studied, little experience in mathematics learning has been reported. However, we have indicated that Web based collaborative learning was effective in a real mathematics classroom setting through our previous work and we will substantiate the effectiveness of such learning in light of new aspects in this paper. First, we briefly survey our previous work and NakSun, which is a bulletin board enhanced knowledge map we developed. Analyzing mathematical activities is observed throughmathematic problem solving in classes at Junior high school. Although in our previous research we provided only open-ended mathematics problems for learners, in this implementation we provided a single-solution problem. In our observation, the correct answer was posed to NakSun at an early stage of collaborative learning. Subsequently, however, we observed many useful mathematical views and ideas entered by the students. This finding indicated that Web based collaborative learning could be applid in a variety of mathematics learning, because the learners can conducteffective mathematical activities on the Web other than the collaborative activities, which aim to get results only.Moreover, although according to previous work the superiority of externalization as a knowledge map was emphasized, our observations showed that time ordered visualization and direct visualization of students' entries were also requiredby learners.
