Fundamental Research of Teachers' Work Station under Multi-Task Computer Environment

为了实现教师工作站（TWS），有两个方面很重要。一是提供大量的物质元素。教师可以在短时间内利用这些材料元素制作教材。二是丰富教材开发方法。去年，我们决定了文本、矢量和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250万个日文字符。科目包括日语、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版权的BUNKEIDO出版社请求允许我们输入并使用教科书作为材料元素。然后，输入选定主题的矢量数据和图像数据。虽然选择的主题不到教科书的1%，但矢量和图像数据的数量占用了10MB以上的硬盘空间。TWS的第二个方面是基于这样一个事实，即对某人来说，习惯的软件工具是最好的工具，即使没有为该工具提供优越的功能。我们为某些工具开发了标准化数据格式和特殊数据格式之间的双向文件格式转换器。日本汉字的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，-。Vec数据格式被广泛使用。为图像数据准备了两种不同的数据格式。今年年底，我们尝试使用材料元素开发教材。我们可以感受到物质元素的有用性和重要性以及数据的兼容性。数据格式和转换方法的技术信息在“本项目报告”中进行了总结。

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.
