Development of Authoring System for Teaching Materials Using Huge Data Storage

本计画的主要工作如下：1）开发一套适合教材制作的大型资料储存设备2）建立教材制作的电脑支援环境1）开发一套以数位录音带（DAT）为基础的储存设备原型。原型机器的型号名称为DF-700。DF-700的内存容量为800 MB。这个容量几乎等于700个2 HD软盘。800 MB的容量足以保存图像数据。本机的特点是：（1）3个驱动器的RAM磁盘存储器改善了磁带机随机存取的缓慢性;（2）DAT到RAM磁盘的加载既可以通过脱机切换，也可以通过联机命令。这些特点对教材的制作和再利用是有益的。关于2），（1）素材元素的数据转换，使许多软件工具成为编辑工具，（2）素材元素的收集是重要的。用于数据转换 ...更多信息 在此基础上，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，我们开发了常驻程序，可以剪切文本和图像中的数据处理中使用任何软件。作为数据的收集，我们输入了25个初中教科书的所有句子。它变成了超过250万个日语字符。科目是日语、社会研究、数学、科学和英语。将矢量和图像数据添加到文本。数据总量将超过1GB。在进行这些活动之前，我们请求拥有这些教科书版权的BUNKEIDO出版社允许我们输入和使用教科书作为材料。通过在多个都道府县的教育中心举办的教师培训项目的试验，制作教材的材料元素的有用性得到了提高。数据格式和转换方法的技术信息在该项目的最终报告中进行了描述。少

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.
