摘要:

分析在线教育系统生成的日志数据是改善教育系统并增加我们对学生学习方式的理解的重要任务。在这项研究中,我们调查了丹麦最大的小学数字学习内容提供商Clio Online以前从未见过的数据。我们考虑了2015-2017年期间14,810名学生的300万次会议的数据。我们分析了学生在一周内的活动。通过使用非负矩阵分解技术,我们得到软聚类,揭示一天中的时间,主题,活动类型,活动复杂性(衡量布卢姆的分类),和性能之间的依赖关系。此外,我们的方法可以跟踪个别学生随着时间的推移的行为变化,以及教育系统中的一般行为变化。根据研究结果,我们提出了行为改变的建议,以优化学习体验,提高绩效。

英文摘要:

Analysis of log data generated by online educational systems is an essential task to better the educational systems and increase our understanding of how students learn. In this study we investigate previously unseen data from Clio Online, the largest provider of digital learning content for primary schools in Denmark. We consider data for 14,810 students with 3 million sessions in the period 2015-2017. We analyze student activity in periods of one week. By using non-negative matrix factorization techniques, we obtain soft clusterings, revealing dependencies among time of day, subject, activity type, activity complexity (measured by Bloom's taxonomy), and performance. Furthermore, our method allows for tracking behavioral changes of individual students over time, as well as general behavioral changes in the educational system. Based on the results, we give suggestions for behavioral changes, in order to optimize the learning experience and improve performance.
