Collaborative Learning Group Formation with Density Clustering
Mengxiong Zhou,Yanming Ye,Yizhi Ren,Yueshen Xu 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.6
The formation of the collaborative learning group is a challenging problem, especially the principle construction and multi-objective optimization. In this paper, we propose an improved density clustering algorithm, and further implement the group formation based on the proposed algorithm. The proposed algorithm first constructs the distance matrix for learners, and clusters learners into different groups. After the random selection of the initial cluster centers, our algorithm achieves superior clustering result by iteratively adjusting the clustering centers. We conduct sufficient experiments and the experimental results demonstrate that the proposed algorithm well satisfies our aim, that is, inter-group heterogeneity maximization and intra-group homogeneity maximization.
Research On Adaptive Courseware By Using SCORM
Yue Shen,Fei Yu,Ying Xu,Ling-fen Zhang 한국어정보학회 2006 한국어정보학 Vol.8 No.1
Sharable Content Object Reference Model is the most widely accepted publication of Advanced Distributed Learning, In this paper, we are going to using SCORM Sequencing Definition model to construct adaptive courseware. At first introduces the architecture of the whole system; Then introduces the way to build adaptive courseware, Finally gives a conclusion and some work in the future.
