【英文摘要】：
Data is an important prerequisite for research on learning analytics. The development of sensing technology has greatly improved the ability of data acquisition in physics learning space and expanded the boundary of learning analytics. In order to grasp the application status and trend of sensing technology, based on the analysis of the characteristics and functions of sensing technology, this paper adopts literature research method to explore the application value of combining sensing data with learning analytics. A framework of learning analytics based on sensing data is constructed, including perceiving learning state, predicting learning performance, intervention and feedback learning process, etc. Based on the existing research results, the application of learning analytics based on sensing data is summarized into three fields: learning cognition, learning emotion and motor skill. Finally, this paper analyzes the challenges of sensor data acquisition, model optimization and feedback mechanism, and proposes the future research directions as well.
