基于大数据技术的学习分析系统架构

Learning analytics system architecture based on big data technologies

通过电子书包、移动学习终端、在线学习应用等,可捕获大量的学习行为数据.如何利用这些大数据是目前教育信息化领域亟需研究的问题.本文首先分析了教育信息化领域对学习分析的需求和研究对象.接着引入大数据技术,设计以Hadoop为核心的学习分析系统,构建基于学习分析的智能数字化教育服务,并列举此技术方案的具体应用案例.最后,提出需要解决Hadoop应用在学习分析领域的技术问题.

First, this paper analyzed the demand and object of learning analytics in the e-Education. Then it introduced the technology of big data, designed learning analytics platform based on Hadoop, built intelligent digital education services supporting platform based on learning analytics, and illustrated the application cases of this technology scheme. Finally, the technical problems of Hadoop which still exist was pointed out, and their solutions was put forward.
