Development of the database type educational system using WWW and CD-Rom

多媒体使新的视听教具得以创造，它吸收了各种图像数据等。此外，充分利用信息检索和编辑功能，有望有效地实用于计算机教学。本研究针对基于结构化数据库的内联网多媒体教学系统的开发进行了以下研究：作为素材库建设的基础研究，以初中数学为研究对象，在学习过程中考察学习者的问题解决过程中所需要的概念、技能等，能够对有效学习的过程进行讨论，能够明确应用问题的解决方法，能够从初中数学教师那里获得解决结构的基本信息。为了解决教师和每个学习者的概念结构，对从小学到初中的部分应用题进行了电子化处理。虽然研究了应用题的特征分析方法和句法分析方法，但没有得到充分方法的决定。设计了一个检索式教育系统的原型，它通过显示适合学习者学习目的的内容来进行学习，进行概念形成，并通过处理文本、图形数据来实现学习，从而实现了对文本、图形数据的处理和动画数据，并输入学习者自己想要学习的内容的关键字。即在WWW服务器上建立素材库的教学系统的基本设计。

Multimedia enabled creation of the new audiovisual education aids which took in various image data etc. Moreover, the effective practical use to the education of a computer is expected by making full use of information retrieval and an edit function. In this study, the as follows study were done aiming at development of an intranet type multimedia education system using the structure-ized database.As basic study of material database construction, focusing on junior high school mathematics, when learning, a learner's problem solving process was examined for required concept, skill, etc.Discussion about the process made to learn effectively was able to be performed, the solution method about an applied problem was able to be clarified, and the basic information which solves structure was able to be acquired from the teacher of a junior high school.In the mathematics of a junior high school etc., in order to solve the structure of the concept of a teacher and each learner, a part of applied problem from an elementary school to a junior high school was processed electronically.Although the method of analyzing the feature of an applied problem was examined and the method of syntactic analysis was examined, it did not result by decision of sufficient method.The basic design of the prototype of a retrieved type educational system by which it learns by showing the contents fit for a learner's learning purpose, conceptual formation is carried out, and learning is realized was performed by being able to handle text, graphic data, and animation data and inputting the keyword of the contents which the learner himself wants to learn. That is, the basic design of an educational system which built the material database to the WWW server was carried out.
