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用于微世界中的教材管理系统。在CAI系统中，教材的复用是系统开发和维护的重要环节。利用该系统可以动态地组合显示在屏幕上的对象并对其进行编程，开发了一个可以对教材进行自由编辑的CAI系统。相反，开发管理功能对于具有很大灵活性的CAI系统来说是非常重要的。因此，我们开发了教材，也开发了CAI系统的管理系统。在本研究中，（1）我们开发了一个教材库，我们可以通过尝试和错误来使用它们。我们开发了如何从教育材料的对象的结构，以及如何使用代码管理它们的代码。教育材料由复数代码组成，我们可以用代码将它们注册到游泳池。(2)当使用者（学习者或教师）使用资源库中的教材时，将相关教材分配到邻近的位置，并对资源库中的教材进行编码分类，使其可视化。我们开发的用户界面，能够无缝使用，对教育材料的使用和管理。我们研究了我们的系统的设计，以便于使用，作为教育材料的布局，数量和大小。

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.
