The development of basic standardized program of micro-computer to display the more real color of chemical substances on CRT.

首席调查员属于教育学院（教师培训学院）。教师培训课程的课程包括广泛的学术领域，因此我们学院的学生必须选择许多课程。化学应该作为一套讲座，练习和实验在任何级别。学生只有经历了大量的化学实验才能掌握，因此必须尽可能多地进行化学实验，即使是通过计算机辅助教学也不行。学生在化学实验中首先对离子反应引起的颜色变化感到惊奇，然后开始对化学产生一定的兴趣。近年来，计算机辅助教学已被广泛应用于化学教学中，但由于CRT显示的颜色种类少，无法再现化学物质的真实的颜色。因此，我们针对如何在CAI教学中再现化学教材中的真实的颜色进行了研究，取得了如下成果：（1）“化学物质的真实的颜色的显示“，J.阿索.化学家个人计算机，（2），75（1989）（2）“用微型计算机显示无机定性分析中沉淀物的真实的颜色“，J.阿索.“用微机显示pH指示剂的真实的颜色变化“，Chem.Education，38（3），338（1990），上述结果可为琦玉大学教师进修班的化学实验教学提供参考。我们学院的学生对这些CAI系统给予了良好的评价。目前，本研究的目的可以认为是在化学实验教学中利用计算机辅助教学系统达到的。

Head investigator belongs to the faculty of education ( teacher training faculty ). The curriculum for teacher training course is included broad academic fields, so students in our faculty must select many courses. The chemistry should be taught as a set of lectures, exercises, and experiments at any level. They could master it only when they have gone through many chemical experiences, therefore they must be given chemical experiments as many as possible, even if by CAI.Students wonder first at the color changes depend on ionic reactions at chemical experiments and then begin to have some interest in chemistry. In recent years, CAI has been adopted in chemical education, but real colors for chemical substances can't be reproduced the because kinds of color displayed on CRT are few. We aimed therefore, how to reproduce the real colors for chemical teaching materials in CAI education.We got the following results and so on ;(1) " Display for real color of chemical substances ", J. Asso. PC for Chemists, (2), 75 (1989)(2) " Display for real color of precipitates at inorganic qualitative analysis by micro-computer ", J. Asso. PC for Chemists, 12(1), 11 (1990)(3) " Display for real color changes of pH indicators by micro-computer ", Chem. Education, 38(3), 338 (1990).These above results could have really contributed to teaching chemical experiments of teacher training course of Saitama university. Students in our faculty have favorably evaluated these CAI systems. Now, the aim of this research could have been considered to be attained in teaching chemical experiments by CAI systems.
