CSCLを用いた高等教育カリキュラムのデザイン実験

―知識構築活動を支援する学習環境の構築―

抄録

This study reports design experiments for a university course with a CSCL system as a knowledge building tool across two consecutive years. The CSCL system used in this study is Knowledge Forum (KF), the second generation of CSILE (Scardamalia, & Bereiter, 1996). About 50 students in each year took the course and engaged in collaborative learning with KF. In the first year, we designed the course with students online communication as the core of the curriculum. Results of their performance on the final essay and discourse activities on KF showed that they worked as independent learners rather than engaged in the practice of collaborative knowledge building. Our lessons from the first years design experiment made us drastically revise the course curriculum so that students in small groups were engaged in more articulate project-based learning through their face-to-face intensive discussion as well as communication between groups on KF. Results showed that the second year students essay performance and discourse activities on KF significantly outperformed those in the first year. The differences in students performance are discussed for drawing some principled knowledge of implementing knowledge media technology like KF in the learning context.
