Development of Educational Materials on Green Chemistry and Fostering Students to Make Their Decisions

1.教材的开发与实践作为绿色可持续化学的范例，我们编写了化工过程变化的教材，并在8所学校和1个教育中心进行了实践。作为实践的结果，我们发现大多数学生对材料感兴趣，并忠实地进行了处理。从基于一页档案袋评价的学习历史记录表的描述来看，学生对科学技术和材料的态度都是积极的，我们通过问卷调查了一年前已经学习过绿色和可持续化学材料的学生，以检验其效果。80%的学生回答了，几乎所有的学生都能正确回答什么是绿色和可持续的化学。60%的学生回答说，他们在过去的一年里有机会记住绿色和可持续的化学，而绿色和可持续的化学知识是有用的。新评价的开发与实践我们制作了基于一页档案袋评价的学习历史记录表，并将其作为评估我们开发的教材效果的方法。此外，我们还制作了类比，以便从定性的角度分析学生在试卷中的描述。实验材料的开发与实践在中学化学教材中，实验中使用的化学物质很少，我们发现用催化剂做实验很困难。我们从预防危险、化学品重复利用和废物处理的角度开发和实践了实验材料。根据学生的要求，还在教材中增加了氨碱法和二氧化硫的实验。

1. Development and Practice of Educational MaterialsWe developed the educational materials on the changes of processes in chemical industries as examples of the green and sustainable chemistry, and practiced them in eight schools and an educational center. As the results of practices, we found the most of students were interested in the materials, and tackled them faithfully. Judging from the description in the learning history sheets based on one page portfolio assessment, students had favorable attitude toward both science and technology and the materials.We asked the students who had learned the material before one year about green and sustainable chemistry by questionnaires in order to check the effects. Eighty percents of the students answered them, and almost all students could answer what is green and sustainable chemistry correctly. And sixty percents of students answered they had the occasions to remember about green and sustainable chemistry last one year, and the knowledge of green and sustainable chemistry was useful.2. Development and Practice of New AssessmentWe made the learning history sheets based on one page portfolio assessment and used them as the method to assess the effects of the educational materials we developed. Besides it, we made rubrics in order to analyze the students' descriptions in the sheets in the point of qualitative view.3. Development and Practice of Experimental MaterialsIn the secondary chemistry textbooks few chemicals were used in experiments, and we found it difficult to do the experiment with catalyses which we planed at the beginning. We developed and practiced the experimental materials in the points of view of prevention of danger, reuse of the chemicals, and treatments of waste. The experiments also developed on ammonia-soda method and sulfuric oxide in the educational materials at students' requests.
