基于xAPI的数字化学习过程数据跟踪

Data Tracking of Digital Learning Process based on xAPI

为了更好地跟踪学习者的学习情况、准确把握学习者的学习能力、客观评价学习者的学习效果,文章提出引入xAPI来解锁LMS的学习过程数据。为此,文章基于对SCORM标准跟踪原理与xAPI跟踪存储原理的对比分析,提出了同步跟踪和异步跟踪两种策略,详细解说了这两种跟踪策略的原理和实现方式,并对同步跟踪策略进行了验证。文章的研究既为数字化学习中对学习者的评估分析提供了数据支持,并可通过数据全面掌控学习者在学习过程中的综合表现,也为基于SCORM的数字化学习注入了活力。

In order to better track learners’learning situation,grasp learners’learning ability accurately and evaluate learners’learning achievement objectively,experience API(xAPI)was proposed to unlock LMS learning process data.Thus,based on the comparison of standard tracking principle of sharable content object reference model(SCORM)and tracking storage principle of xAPI,two strategies of synchronous tracking and asynchronous tracking were proposed.Meanwhile,the principles and implementation methods of two tracking strategies were explained in detail,and the synchronous tracking strategy was verified.The research in this paper provided data support for the evaluation analysis of learners in digital learning,grasped learners’comprehensive performance in learning process through data thoroughly,and injected vitality into digital learning based on SCORM.
