Development of quantitative experimentation for school environmental education and scientific training of teachers

本研究以促进科学教育实验、提高教师的科学教学能力为目的，开展了适合初、高中环境教育的环境安全定量实验，并对教师进行了科学培训示范。1）改进了内陆水分析方法，使其不使用有毒物质、PRTR材料，减少了实验浪费。2）在比色分析中，通过改变还原剂的种类，使显色移到人类易于识别的波段。3）可以对标准色谱柱的判别进行感官信息分析。4）制作了简易光电比色仪，并对教师进行了水质分析的培训。5）利用色度计分析内陆水的环境安全性进行了科学教师培训，取得了较好的效果。我们开发环境安全教育和教师培训计划。

The aim of this study is promote science education experiment and skill up scientific teaching for teachers.We developed the environmental-safety quantitative experimentation for junior, senior high school environmental education and demonstrated scientific training of teachers.1) We improved inland water analytical method for without using poisoning substance, PRTR material, so reduce experimental waste. Teacher training of scientific experiment and observation carried out this method.2) On the colorimetric assay, by changing the type of reducing regent, it was made to shift for the coloration in wavelength band which the human is easy to recognize. It is able to determine the quantitative analysis easily.3) It was possible that on the discrimination of standard color columns carried out the sensory information analysis.4) Simple photoelectric colorimeter was made, and we are training analysis of water to teachers. This is proven to be effective.5) The analysis of the environmental safety inland water using colorimeter is carried out into science teacher training, it has been effective. We develop the environmental safety education and teacher training program.
