Multi-Media Instructional Materials for Promoting Children's Understanding

本研究以认知模型解释儿童的理解过程，探讨多媒体教材的建构方法，开发多媒体教材的创作工具，并提出如何运用多媒体教材对儿童进行教学。本研究的主要成果如下：1、运用认知科学中的交互作用分析和心理模型理论来考察儿童的理解过程。提出了利用小学和初中数学教材促进儿童理解的建议。在此基础上，对超媒体的教育功能进行了思考从教育应用的角度出发，对超媒体图像数据库进行了研究。hypercard开发并安装了基于关键词的图像数据分类检索工具利用动态链接功能，开发了一个能够处理卡片属性和卡片间关系的创作工具。该工具既能满足幼儿查找卡片的目的，又能为教师提供更轻松的创作环境在HyperCard中编写了一些关于科学和社会研究的教学材料。运用社会学教材进行教学的计划和有效实施。

This research is made to explain the process of children's understanding with cognitive models, to investigate the method to construct multi-media instructional materials, to develop authoring tools, and to propose how to teach children by using multi-media instructional materials.Main results of our research are as follows :1 The processes of children's understanding are considered by using the interaction analysis and the mental model theory in cognitive science. A proposal on the assistance to promote children's understanding is made by using the instructional materials of mathematics in elementary school and junior high school. On the base of these results, the educational functions of hypermedia are considered.2 From the viewpoint of educational use, hypermedia image databases are considered. The tools that classify and retrieve image data by using key words are developed and installed in HyperCard.3 An authoring tool, which is able to deal with the attributes of cards and the relations between cards, is developed by using dynamic link function. This tool is able to accept the children's purpose of search for cards, and to provide teachers more ease authoring environment.4 Several instructional materials on science and social studies are developed in HyperCard. A teaching using the instructional material of social studies is planned and put into practice effectively.
