项目摘要

The main activities of this project was as follows.1) The development of a large data storage equipment suitable for making teaching materials2) To establish the computer supported environment for making teaching materialConcerning 1), we could develop a prototype memory equipment which was based on digital audio tape (DAT). Model name of the prototype machine was DF-700. DF-700 has a memory capacity of 800MB. This capacity is nearly equal to 700 2HD floppy disks. The capacity of 800MB was enough for saving image data. The characteristics of this machine are ; (1) RAM disk memory of 3 drives improves the slowness of random access of tape device, (2) loading from DAT to RAM disk can be done by both offline switch and online command. These characteristics are useful for making and re-using of teaching materials.Concerning 2), (1) data conversion of material elements for enabling many software tools as the editing tools, and (2) collecting material elements are important. For data convers … More ion, we decided the standard formats of text, vector and image data. These formats are widely used or treatable by software tools. We developed bi-directional data converters between these standard formats and the special formats for some software tools. Moreover, we developed the resident program which can clip texts and images in the midst of data processing using any software.As the collection of data, we inputed all the sentences of 25 textbooks for lower secondary school. It became more than 2.5 million Japanese characters. The subjects were Japanese, Social Studies, Mathematics, Science, and English. Adding vector and image data to text. The total size of data will become more than 1GB. Before doing these activities, we asked BUNKEIDO Publisher, who had Copyrights of these textbooks, to allow us to input and to use textbooks as the material elements. The usefulness of material elements for making teaching materials are improved by the trial of teacher training program held by Education Centers in many prefectures.Technical Information of data formats and conversion methods are described in Final Report of this project.

本项目的主要工作如下：1)开发适合制作教材的大型数据存储设备；2)建立计算机支持的教材制作环境；1)开发一个基于数字音频磁带(DAT)的存储设备原型。样机型号为DF-700。东风-700的内存容量为800MB。这个容量几乎相当于700张2HD软盘。800MB的容量足以保存图像数据。这台机器的特点是：(1)3个驱动器的RAM磁盘存储器改善了磁带设备随机访问的速度；(2)从DAT到RAM磁盘的加载可以通过离线开关和在线命令来完成。这些特点对于教材的制作和再利用是非常有用的。要注意2)，(1)素材元素的数据转换，使许多软件工具能够作为编辑工具，以及(2)素材元素的收集是重要的。对于数据转换器…进一步确定了文本、矢量和图像数据的标准格式。这些格式被广泛使用或可由软件工具处理。我们开发了这些标准格式和一些软件工具的特殊格式之间的双向数据转换器。此外，我们还开发了一个常驻程序，可以使用任何软件在数据处理过程中对文本和图像进行裁剪。作为数据的收集，我们输入了25本初中教科书的所有句子。它变成了超过250万个日语字符。这些科目包括日语、社会研究、数学、科学和英语。将向量和图像数据添加到文本。数据的总大小将超过1 GB。在进行这些活动之前，我们请拥有这些教科书版权的BUNKEIDO出版商允许我们输入和使用教科书作为材料元素。通过多地市教育中心开展的教师培训项目的试点，提高了教材制作材料要素的实用性。本项目的最终报告中介绍了数据格式和转换方法的技术信息。较少
