Development of Questionnaire in Internet answering intelligibly about Chemical Concept and Phenomena.

琦玉大学教育学部化学实验室主页是为理科（化学）教育而开发的。本报告介绍了其主页的内容和进展情况。主要内容包括问卷调查、自动化（服务器端）。服务和模拟化学实验。在过去的两年里，问卷板上写了68个问题。对这些问题的易懂答案已尽快通过电子邮件发送，并在董事会上公开。大多数问题都很简单，但很难回答，例如，光和颜色、溶解现象、电子壳层和化学键、酸和碱、氧化和还原、气体和蒸汽、溶液制备等。已经开发了使用互联网的计算数据和水溶液（盐溶液、盐酸、乙酸溶液、氨水和氢氧化钠溶液）制备的自动服务。这些程序可以下载并离线运行。还开发了利用互联网的自动服务器端服务，用于回归分析和绘图。这些程序处理的文件是Microsoft Excel类型和Java Applet类型。已经开发了用于模拟酸碱滴定（盐酸或乙酸溶液-氢氧化钠溶液或氨水）的自动服务。

Home page of Chemical Laboratory in Faculty of Education of Saitama University has been developed for science (chemical) education. This report describes its contents and progress of the home page. The main contents are composed of questionnaire, automatic (server side.) services, and simulation of chemical experiments. Sixty-eight questions have been written on the questionnaire board during the past two years. The intelligible answers to these questions have been sent by e-mail as soon as possible and opened publicly on the board. Most of the questions are unsophisticated, but difficult to answer, e.g., light and colors, dissolution phenomena, electron shell and chemical bonds, acid and base, oxidation and reduction, gas and vapor, preparation of solutions, etc. Automatic services by using internet have been developed for calculated data and preparation of aqueous solutions (saline solution, hydrochloric acid, acetic acid solution, ammonia water, and sodium hydroxide solution). These programs can be downloaded and run off line. Automatic server side services by using internet have been also developed for regression analysis and drawing. The files treated with these programs are Microsoft Excel type and Java Applet type. Automatic services have been developed for simulation of acid-base titration (hydrochloric acid or acetic acid solution -sodium hydroxide solution or ammonia water).
