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.
