Improvement of educational material based on learner' s biological data

许多研究都集中在学习支持系统技术上。随着网络和多媒体技术的发展，各种基于网络的自主学习培训系统应运而生。WBT的主要优点是，在网络环境下，无论是在大学还是在家里，学生都可以保持自己的学习节奏。另一方面，然而，一些学生可能会发现在一个孤立的环境中很难集中注意力学习；因此，如何保持学生的兴趣对WBT来说是很重要的。目前大多数基于网络的学习支持系统同步复制教师在其讲座中使用的视频和Microsoft PowerPoint幻灯片等讲座资源中的内容。这些系统在确认和/或复习讲座中可能错过的任何部分时非常有用。然而，他们没有考虑到学生在讲课时的注意力水平。为了解决上述问题，我们开发了一个具有自主学习支持功能的多媒体讲座系统。该系统将通过引入从每个学生的生理数据中提取的唤醒水平，帮助学生更有效地复习课程。多媒体讲座系统不仅提供了讲座资源中的多媒体内容，而且利用上述唤醒级别和讲座信息(如：大肠的问题/答案)。此外，该系统的用户界面专门针对交互式材料编辑界面进行了设计。

Many studies have been conducted focusing on the technology of learning support systems. With the progress of networks and multimedia technologies, various types of web-based training(WBT) systems have been developed for self-learning. The main advantage of WBT is that a student can keep his/her own pace when learning at university or at home under a network environment. On the other hand, however, some students may find it difficult to concentrate their attention on learning in an isolated environment ; therefore, it is important for WBT how to keep the students' interest. Most of the current support systems for web-based learning synchronously reproduce contents in lecture resources such as videos and Microsoft PowerPoint slides that a teacher uses during his/her lecture. These systems are very useful when confirming and/or reviewing any parts of the lecture that may have been missed. However, they do not take into consideration the attention level of the students during lectures. We have developed a multimedia lecture system with self-learning support functionalities to solve the above problem. The system will help students to review lectures more efficiently by introducing the arousal level, extracted from each student' s biological data. The multimedia lecture system provides not only multimedia contents in lecture resources but also various functionalities matched to student learning level by using the above-mentioned arousal level together with lecture information(i. e. questions/answers). Furthermore, the user interface of the proposed system is designed specifically for interactive material editing interface.
