xAPI解决了传统SCORM标准存在的结构复杂性以及数据传递单一性等问题，以“活动流”的形式更加有效地支持开放学习环境下对学习者的全面评价和个性化学习支持服务。文章通过对xAPI数据标准以及开放学习者学习行为分析，发现：（1）通过对开放学习者的学习行为进行语义分解，总结并扩展了20个“以学习者为中心”的学习行为动词；（2）提出基于xAPI的开放学习分析架构以及开放学习者行为分析模型，以更好地支持开放学习数据挖掘和学习分析；（3）以一位开放学习者的xAPI格式下的学习行为数据为例，进行开放学习者行为画像分析，为全面理解xAPI在支持开放学习者行为分析方面的作用具有重要意义。
【英文摘要】：
Experience API can support comprehensive evaluation and personalized learning support service for learners in open learning environment in the form of "activity flow", which breaks through the boundaries of traditional SCROM standards such as structure complexity and the monotony of data transfer. Through the analysis of xAPI data standards and open learners' learning behaviors, this paper summarizes and expands 20 "learner-centered" learning behavior verbs based on semantic decomposition of open learners’ learning behaviors. Also this paper puts forward an xAPI-based open learning analysis framework and a behavior analysis model of open learners in order to better support data mining and learning analysis of open learning. Moreover, taking the learning behavior data of an open learner under xAPI format as an example, this paper carries out behavior profiling analysis, which is important to fully understand the role of xAPI in supporting behavior analysis of open learners.
