基于xAPI学习记录的LMS网络系统架构研究

Research on LMS Network System Architecture Based on xAPI Learning Record

对学习者网络学习行为记录的标准是在线学习个性化研究和应用的基础。目前，SCORM标准结构的复杂性以及数据传递单一性等问题导致其无法获取完整的自身学习行为记录，特别是对于移动学习和个性化学习无法进行充分有效地支持。本文对xAPI(Experience API)规范下的网络学习模型进行了详细分析，对相关模型要素进行了语义成分分解，并针对学习管理系统(LMS)不同搭载源架构提出了基于xAPI学习记录的LMS网络系统三种架构的重构模式，从而支持xAPI规范下将LMS学习行为记录完整精确地传输到学习记录系统，实现跨学习环境的学习记录多维度分析，更好地支持数字化学习环境中的移动学习和个性化学习研究。

Standards to learner’s record of learning behavior is the basic of a personalized online learning research and applications. On account of the complexity of the structure and simplicity of the data transmission， the SCORM make it unable to obtain complete learning record. It cannot offer support for mobile learning and individual learning effectively. According to different platforms， under the analysis of the network learning model and relevant semantic elements， this paper presents three kinds of reconstruction models of LMS network system architecture based on xAPI learning record. In the xAPI specification， learning record can be transferred from LMS to Learning Record System completely， which can achieve multidimensional analysis for cross environment learning record， and that will lead to a better support for mobile learning and individualized learning.
