教育大数据的平台构建与关键实现技术

Platform Construction and Key Implementation Technologies of Educational Big Data

大数据现已成为驱动教育变革与创新的强劲力量,而平台建设是教育大数据落地的关键之所在,它覆盖了从数据采集、存储计算、分析挖掘到具体应用的整个生命周期。文章首先从广义的角度,对教育大数据的内涵进行了再认识。随后,文章基于教育大数据平台的需求分析,设计了教育大数据平台的架构。最后,文章从学习行为大数据采集、教育大数据存储与计算以及教育大数据分析挖掘三个方面,对平台的关键实现技术进行了研究。文章的研究可为教育大数据的理论研究与实践应用打下平台基础。

The big data has become to be a powerful driving force for educational reform and innovation. In addition, the platform construction is the key to the landing of educational big data, which covered the entire life cycle from data acquisition, storage calculation, analysis mining to specific application. Firstly, this paper recognized the connotation of educational big data from a broad perspective. Then, the architecture of the platform for educational big data was designed based on the requirements analysis of the platform for educational big data. Finally, this paper investigated the key implementation technologies of the platform from three aspects of the big data acquisition of learning behavior, data storage and computing of educatior^al big data, and the analysis mining of educational big data. The results of this paper could lay a foundation for the theoretical research and practical application of educational big data.
