Practical Approach to Teaching Scientific Fundamentals from Computer Mechanisms using Multimedia

科学基础教学的难点之一是如何让学生认识到科学基础为什么如此重要和有用。因此，本研究试图通过教授学生通常更感兴趣的计算机机制来教授科学基础知识来解决这一问题。例如，计算机的每个部件都可以用科学的基础原理和理论来解释；数学、物理等。我们利用多媒体对这些在线内容进行了实践研究。以学习管理系统（LMS）为主要内容，开发了在线教材、小测验、Java可视化小程序、Java3D虚拟实验、网络远程实验等；WebCT， Moodle等。国际化与地区系统和IMS实现了可移植性。远程实验不仅支持Java小程序，还支持简单的telnet命令与远程传感器通信。对于大型系统来说，多台服务器之间的协作是非常方便的，有时也是必要的，然而，它会在不同的服务器上产生身份验证问题。我们通过支持CAS和实现单点登录系统来解决这些问题。这种身份验证还可以为每个学生保存自己的模拟参数。在名为“熊本互联网Shiminjyuku”的NPO上，不仅可以为大学生提供学习内容，也可以为终身学习者提供学习内容。

One of the difficulties of teaching scientific fundamentals is how to make students recognize why scientific fundamentals are so important and useful. This study, therefore, tried to solve this problem by teaching scientific fundamentals through teaching computer mechanisms which are usually more interesting for students. For example, each computer part can be explained principally and theoretically by scientific fundamentals ; Mathematics, Physics etc. We did practical study on such online contents using multimedia.Online textbooks, quizzes, Java applets for visualization, virtual experiments using Java3D, remote experiments over the Internet etc. were developed as the contents mainly on Learning Management System (LMS) ; WebCT, Moodle and so on. The internationalization with locale system and IMS were implemented for portability. The remote experiments supported communications to remote sensors not only by Java applets but also by a simple telnet command. Cooperation of several servers is very convenient and sometimes necessary for large systems, however, it makes authentication problems on different servers. We solved these problems by supporting CAS and realizing a single sign-on system. This authentication also make possible to save own parameters on a simulation for each students. The learning contents can be available not only for university students but also life-long learners on the NPO named "Kumamoto Internet Shiminjyuku".
