项目摘要

In order to realize a Teacher's Work Station (TWS), two aspects are important. One is to supply huge amount of material elements. Teachers can produce teaching materials using these material elements in a short time. The other is to enrich methods for developing teaching materials.Last year, we decided the standardized data formats for texts, vectors and images. This year, we input all the sentences of 25 textbooks. It became more than 2.5 million Japanese characters. The subjects were Japanese, Social Studies, Mathematics, Science, and English. 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.Then, we input vector data and image data for selected topics. Although the selected topics were less than 1% of the textbooks, the amount of vector and image data occupied more than 10MB of a harddisc space.The second aspect of TWS is based upon the fact that the accustomed software tool for a somebody is the best tool even if the superior functions are not provided to the tool. We developed several bi-directional file format converters between the standardized data format and the special data format for some tool. Shift JIS code for KANJI characters is now common to many personal computers. Concerning the vector data format, -. vec data format is widely used. Two different data formats are prepared for image data.At the end of this year, we tried to develop teaching materials using material elements. We could feel the usefulness and importance of material elements and compatibilities of data.Technical Information of data format and conversion methods are summarized in "Reports of this project.

为了实现教师工作站（TWS），两个方面是重要的。一是提供大量物质要素。教师可以在短时间内使用这些材料元素制作教材。二是丰富教材开发手段，去年确定了文本、矢量、图像的标准化数据格式。今年，我们输入了25本教科书的所有句子。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。在进行这些活动之前，我们向拥有这些教科书的著作权的BUNKEIDO出版社请求，允许我们输入和使用教科书作为素材。然后，我们输入了选定主题的矢量数据和图像数据。虽然所选题目不到教科书的1%，但矢量和图像数据量却占据了超过10 MB的硬盘空间。TWS的第二个方面是基于这样一个事实，即即使没有为工具提供上级功能，某人习惯的软件工具也是最好的工具。我们开发了几个双向文件格式转换器之间的标准化数据格式和特定的数据格式的工具。汉字字符的Shift JIS代码现在在许多个人电脑上都很常见。关于矢量数据格式，-。广泛使用VEC数据格式。为图像数据准备了两种不同的数据格式。今年年底，我们尝试使用素材元素开发教材。我们可以感受到物质元素和数据兼容性的有用性和重要性。数据格式和转换方法的技术信息总结在“本项目报告”中。
