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

首席调查员隶属于教育学院（教师培训学院）。教师培训课程涉及面广，因此我校学生必须选课较多。化学应该以一套讲座、练习和实验的形式在任何层次进行教学。他们只有经过大量的化学实验才能掌握化学知识，因此必须尽可能多地给他们做化学实验，即使是通过CAI。学生们首先对化学实验中离子反应引起的颜色变化感到惊奇，然后开始对化学产生兴趣。近年来，化学教学中已采用CAI，但由于CRT上显示的颜色种类较少，无法再现化学物质的真实颜色。因此，如何在CAI教学中再现化学教材的真实色彩是我们的目标。我们得到了以下结果；(1)“化学物质的真实颜色显示”，J. Asso。(2)“用微型计算机显示无机定性分析中沉淀的真实颜色”，陈志强，陈志强。化学计算机，12(1),11(1990)(3)“用微机显示pH指示剂的真实颜色变化”，化学。教育，38(3),338（1990）。以上结果对埼玉大学教师培训课程的化学实验教学有一定的帮助。本系学生对这些CAI系统评价良好。现在，本研究的目的可以认为是在化学实验教学CAI系统中达到的。

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.
