大数据背景下学习分析可视化呈现技术研究

The Research Status and Future Prospect of Big Data-Based Learning Analysis

大数据背景下,个性化学习和自适应学习的需求对学习者泛在学习过程的监测、反馈、评价提出要求,以此为目的的学习分析技术应运而生。学习分析可视化呈现技术是学习分析应用与实践中重要的一个环节,其直接关系到服务对象的使用体验与沟通效果。该文讨论了数据可视化技术的内涵和特征,学习分析可视化的价值,梳理了学习分析可视化常用工具,探讨了学习分析可视化呈现系统架构,为相关学习分析系统构建和实践研究提供借鉴。

In the background of large data,personalized learning and adaptive learning are needed to be monitored, be fed back and be evaluated, and the learning analyst techniques for this purpose come into being. Learning analysis Visual presentation technology is an important part of learning analyst application and practice, which is directly related to the service experience and communication effect of service object. This paper discusses the connotation and characteristics of data visualization technology,analyzes the value of visualization, analyzes the common tools of learning analyst visualization, discusses the architecture of learning analysis visualization presentation system, and provides reference for the construction and practice of related learning analysis system.
