摘要

电子学习的有效交付依赖于对学生注意力的持续监控和管理。在传统的课堂环境中,教师可以很容易地通过凝视线索来评估人群的注意力,而这些线索在在线学习环境中基本上是不可用的。为了应对这一挑战并突出我们研究的重要性,我们收集了20名学生的眼动数据,并开发了四种可视化方法:(a)热图,(b)椭圆图,(c)两个移动条,(d)垂直条,这些方法覆盖在13个教学视频上。我们的研究结果揭示了教师们意想不到的偏好。与预期相反,他们并不喜欢在线直播教学的既定热点图和竖条。相反,他们选择了侵入性较小的椭圆可视化。尽管如此,热图仍然是回顾性分析的首选,因为它的信息更详细。重要的是,所有的可视化都被发现是有用的,有助于恢复在线学习中的情感联系。总之,我们创新的人群注意力可视化显示出广泛应用的巨大潜力,从电子学习扩展到所有在线演示和回顾性分析。我们研究的重要结果强调了这些可视化将在提高未来电子学习体验的有效性和情感联系方面发挥关键作用,从而促进教育前景。

Behind the Screens: Exploring Eye Movement Visualization to Optimize Online Teaching and Learning
The effective delivery of e-learning depends on the continuous monitoring and management of student attention. While instructors in traditional classroom settings can easily assess crowd attention through gaze cues, these cues are largely unavailable in online learning environments. To address this challenge and highlight the significance of our study, we collected eye movement data from twenty students and developed four visualization methods: (a) a heat map, (b) an ellipse map, (c) two moving bars, and (d) a vertical bar, which were overlaid on 13 instructional videos. Our results revealed unexpected preferences among the instructors. Contrary to expectations, they did not prefer the established heat map and vertical bar for live online instruction. Instead, they chose the less intrusive ellipse visualization. Nevertheless, the heat map remained the preferred choice for retrospective analysis due to its more detailed information. Importantly, all visualizations were found to be useful and to help restore emotional connections in online learning. In conclusion, our innovative visualizations of crowd attention show considerable potential for a wide range of applications, extending beyond e-learning to all online presentations and retrospective analyses. The significant results of our study underscore the critical role these visualizations will play in enhancing both the effectiveness and emotional connectedness of future e-learning experiences, thereby facilitating the educational landscape.
