【摘要】 实时采集并分析课堂学习状态,有助于教师及时掌握课堂动态、提升教学效果,但现有的方法存在实时性较弱、准确率不高等问题。对此,文章提出了一种包含学习状态判定标准、学习状态识别方法和课堂表现实时评价方法的学习状态实时采集与动态分析(Learning Status Real-time Collection and Dynamic Analysis,LRD)方法。文章首先阐释了LRD方法的工作原理,之后研发了课堂学习状态实时采集与动态分析系统,最后通过此系统的性能实验和有效性实验,验证了LRD方法具有实践可行性和有效性。文章提出的LRD方法能够实时、准确地识别和分析学生的学习状态,提高教师掌握学生课堂表现的水平,为智慧教育的发展提供了一种新的研究思路和技术储备。更多还原

【Abstract】 Real-time collection and analysis of classroom learning status can help teachers grasp classroom dynamics in time and improve teaching effect, but the existing methods have problems of weak real-time and low accuracy. In this regard, the paper proposed a learning status real-time collection and dynamic analysis(LRD) method containing the criterion of learning status, the recognition method of learning status and the real-time evaluation method of classroom performance. Firstly, this paper explained the working principle of the LRD method. Secondly, a classroom learning status real-time collection and dynamic analysis system was developed. Finally, by the property and effectiveness experiments of this system, the practical feasibility and effectiveness of the LRD method were validated. The LRD method proposed in this paper can identify and analyze students’ learning status in real time and accurately, improve the level of teachers to grasp the students’ classroom performance, and provide a new research idea and technical reserve for the development of wisdom education.更多还原
