Study of Presentation and Management for the Educational Materials in the Science-Experiment Microworld

本项目的目的是开发一个Microworid教材管理系统。教学素材在计算机辅助教学系统中的重用，对系统的开发和维护具有重要意义。我们的系统可以动态地合成屏幕上可视化的对象并对其进行编程，我们开发了一个可以自由重新编辑教材的计算机辅助教学系统。相反，对于具有很大灵活性的计算机辅助教学系统来说，开发一个管理功能是非常重要的。因此，我们开发了教材，并为我们的计算机辅助教学系统开发了一个管理系统。在本研究中，(1)我们开发了一个可以通过反复试验使用的教材池。我们开发了如何从教育材料对象的结构中生成代码，以及如何使用这些代码来管理它们。教育材料由多个代码组成，我们可以将它们与代码一起注册到池中。(2)当用户(学习者或教师)使用资源库中的教材时，相关的教材被分配到附近，我们考虑了将资源库中的教材按代码分类的方法，使其可视化。我们开发了能够无缝使用的用户界面，用于教育材料的使用和管理。我们检查了我们的系统的设计，以便于使用，如布局，数量和教育材料的大小。

The aim of this project is to develop a management system for the educational materials in the Microworid. Reuse of educational materials in a CAI system, is important to develop and maintain the system. Our system which can dynamically compose the objects visualized on the screen and program it, we have developed the CAI system which can re-edit the educational materials freely. On the contrary, developing a management function is important for the CAI system which has a lot of flexibility. We have therefore developed educational materials, and developed a management system for our CAI system, too.In this study, (1) we developed a pool of educational materials in which we can use them through a trial and error. We developed how to make codes from the structure of objects of educational materials and how to manage them using the codes. Educational materials consist of plural codes and we can register them with the codes to the pool. (2) When the users (learners or teachers) use the educational materials in the pool, the correlative educational materials are assigned to near.We considered the method to categorize the educational materials in the pool by codes, to visualize them. We developed user interfaces which are able to use seamlessly, on using and management of educational materials. We examined the design of our system to use easily, as the layout, number and size of educational materials.
