教育数据可视化:发展历史、研究热点及典型应用

Visualization of Educational Data:Development History,Research Hotspots and Typical Applications

随着大数据兴起,各领域掀起了大数据分析的浪潮,教育领域也不例外。近年E-learning的兴起形成了教育数据的海量存储,构成教育大数据。教育数据可视化即对教育大数据进行可视化分析,为学生、教师、家长等不同角色人群带来极大便利,在教育领域中存在着巨大潜在价值。与国际相比,我国的教育数据可视化起步较晚,研究与应用探索尚待进一步加强。文章基于citespace文献分析法,追溯了数据可视化从古至今的历史渊源,分析了数据可视化在教育领域的发展趋势和热点主题研究,重点探讨了数据可视应用载体的典型代表--学习仪表盘在教育领域的应用,指出在线学习系统可视化过程中存在的问题,并提出应在未来应用中注重隐私保护、关注学习风格、加强用户反馈,引入动态交互、融合线下数据等相关举措,借此为教育大数据可视化的发展研究提供可行性参考和借鉴。

With the rise of the era of big data,there has been a wave of big data analysis in all fields,and the field of education is no exception.The rise of E-learning in recent years has made it possible to mass-store educational data,and at the same time it has formed educational big data.The visual analysis of educational big data can bring great convenience to people of different roles such as students,teachers and parents.In the field of education,there is huge potential value.For example,it can realize the teaching of students in accordance with their aptitude and achieve individuality.Based on the literature analysis method,this paper traces the historical origin of data visualization from ancient times to the present,analyzes the development trend and hot topic research of data visualization in the field of education,and focuses on the typical representative of data visualization-the application of learning instrument panel in education field,so as to provide a feasible reference for the development of educational big data visualization.
