Abstract
Based on the theory of concept mapping, this study combined co-creation and sharing of Web 2.0, and developed the Collaborative Concept Mapping System for elementary school students. The greatest feature of this system was its capability in providing two mapping models for individuals and their groups. Students could perform individual mapping through this platform and then join the collective collaboration to construct the group concept mapping. At the final stage, teachers' guidance and sharing were included. According to the preliminary feedback from students and teachers, this system not only enhanced students' concentration while learning, but also improved their conceptualization and speculation.
