Development and Valuation of a Chemical Education System Using a Graphic Data Base of 3-D Structure of Molecules

现代文明的生活方式和我们的生活是由许多化学物质来支撑的。相应地，人们需要更多地了解化学物质的作用和性质。为了进行化学教学，我们开发了一个以分子三维结构图形数据库为基础的微机辅助教学系统。该系统由七个软件组成，包括：（1）名称、分子式、分子量、分子式、和化合物的分子结构，（2）球杆模型和空间填充模型的分子图形和立体视觉，（3）物理性质、来源、制备方法、反应、用途的简要信息，这些软件被命名为“分子电子图鉴”，因为它们以3-每个软件的标题分别为（1）“基本有机化合物”、（2）“分子与生命”、（3）“蛋白质与核酸”、（4）“生物活性物质”、（5）“基本有机化合物2”、（6）“富勒烯C_ -C_的分子数据分子图形<60><84>“和（7）“一个学习化学的软件：这些软件作为自由软件由日本化学软件协会公开，受到高度评价，并于1994年获得该协会的“技术”奖。不久的将来，这些软件将集成并以光盘形式出版。进一步计划开发一种多媒体软件，将生活必需品和自然资源的静止视频或视频与分子图形联系起来。

Today, a civilized way of living and our lives are supported by many chemical substances.Accordingly, people need to know more of the roles and the properties of chemical substances.For chemical education we have developed a micro-computer aided instruction system using a graphic data base of 3-D structure of molecules.The system consists of seven softwares which contain (1) names, molecular formulae, molecular weights, and molecular structures of compounds, (2) the molecular graphics both ball-stick model and space filling model and stereovision, (3) brief informations on physical properties, the origin, methods of preparation, reaction, uses, bio-activities of about 500 species of compounds.These softwares were named "Electronic picture book of molecules" because they are characterized by 3-D molecular graphics.The titles of each software are (1)"Basic organic compounds", (2)"Molecules and life", (3)"Protein and nucleic acids", (4)"Bio-active substances", (5)"Basic organic compounds 2", (6)"Molecular data molecular graphics of fullerenes C_<60>-C_<84>", and (7)"A software for learning chemistry : The world of molecules illustrated by pc".These software were open to the public by the chemical software society of Japan as free software and valued highly and awarded a "technical" prise of the society in 1994.In the near future these softwares will be intergrated and published using CD-ROM as media.The development of a multimedia software which connects still-video or video of the necessities of life and natural resources with graphics of molecules is planned further.
