许多研究证明，持续的注意力对学生的学习成绩有很大的影响。然而，教师要及时感知每个学生的注意力水平是一个挑战，特别是在在线学习环境和大规模的物理课堂中。在这项研究中，我们提出了一种评估学生注意力水平的方法，该方法使用可穿戴设备测量的光电容积描记图（PPG）信号，平均精度为0.69。一种新型的注意力监测系统是在一个大规模的开放式在线课程（MOOC）环境中为教师和学生用户开发的，该环境提供了一个方便的界面，用于可视化单个学生和学生群体的实时注意力水平。为了验证该系统的可靠性，在MOOC环境下进行了一项实证研究，初步探讨了注意状态与学习内容的关系。本研究的结果提供了一个宝贵的资源，选择和设计视频讲座的在线学习。该系统还可以扩展，以提供适当的调整，在课堂和无处不在的学习环境。
Many studies have proved that sustained attention strongly affects student learning performance. However, it is challenging for teachers to perceive the attention level of every student in time, especially in online learning environments and large-scale physical classes. In this study, we propose a method for assessing students’ attention levels that uses a photoplethysmogram (PPG) signal measured by a wearable device, with an average accuracy of 0.69. A novel attention monitoring system was developed for both teacher and student users in a massive open online course (MOOC) environment that provides a convenient interface for visualizing the real-time attention levels of both individual students and groups of students. In order to verify the reliability of the system, an empirical study was conducted in the MOOC environment for a preliminary exploration of the relationship between attention states and learning content. The results of this study provide a valuable resource for selecting and designing video lectures for online learning. The system can also be extended to provide appropriate adjustments in both classroom and ubiquitous learning environments.
