基于网格的协同学习环境资源管理模型研究与实现

研究表明协同学习具有更好的学习效果，但通过计算机技术构建协同学习环境对资源管理有着特别的、更高的要求，目前的学习管理系统很难适应和达到协同学习环境对资源管理的需要。在分析目前主流学习管理系统在资源管理方面缺失的基础上，引入网格资源管理中间件GRAM，构建了一种基于网格的协同学习环境资源管理模型。并选择开源的、成熟的I_inux, Apachc, MySQI、和PHP构建实验实施环境，采用〔}`I}4作为网格服务，对模型进行了测试，实验结果表明实现了模型的设计预期，能够较好地支持协同学习环境资源管理的需要。

Research and Implementation on Grid-based Resource Management Model for Collaborative Learning Environments

Collaborative learning is a more effective approach than other learning under many circumstances, but the construction of collaborative learning environment is very difficult because of the high requirements met the resource management. Now it is hardly any learning management systems met the requirements of resource management in collaborative learning environment. In this paper, based analyzing the drawbacks of resource management in the mostly popular learning management system, we introduced grid resource management middleware-GRAM(the Grid Resource Allocation Manager) , and presented one resource management model for collaborative learning environment based grid.The model is tested with implementation of the open source, matured technologies including Linux, Apache, MySQL and PHP, and adopting GI'4 as grid services, the results show that expected design of the model is realized, and the the model could well surport the requirements of resource management in collaborative learning environment.
