摘要
根据协作学习中学习者的关键特征类型,以异质分组为原则,设计了适用于计算机网络环境下的自动分组模型,给出了分组算法关键技术,进而采用PHP+Apache+MySQL组合技术开发了协作学习小组分组系统.该系统支持协作小组分组的自动实现,具有自主分组、异质分组、随机分组和同伴关系分组等功能,为协作学习提供了一个自动分组的支撑环境,是CSCL教学和研究的一种有效支持工具.
Computer- Supported Collaborative Learning （CSCL） is based on the learning groups with the help of the computers. Proper method of grouping can promote cooperation in learning procedure. The different forms of group formation produce different peer relationship and group structure that affect the quality of groups, including initiative, schedule, learning target and learning effect, Based on the students＇ characteristics in CSCL, the design of Group Formation System for collaborative learning groups in CSCL with the core of group formation according to the heterogeneous grouping is presented, and the detailed heuristic algorithms to form groups are given. Finally, the implementation of the system with PHP ＋ Apache ＋ MySQL technology to support the automatic group formation is described, The system has such functions as involuntary group formation, heterogeneous group formation, random group formation and partnership group formation, and so on. It can be applied to collaborative learning environment for automatic group formation independently and support the implementation and research of CSCL.
