A Study On Greening Of Chemical Experiment In High School Chemical Experiment Teaching

Sustainable development calls for Green Chemistry which belongs to the new development and important feature of modern chemistry. All the countries nowadays are carrying out the research of Green Chemistry, and paying great attention to the education of it. How to infiltrate Green Chemistry education into chemical education is a new research topic of the era. The newly-formulated Chemistry Curriculum Standard of High School (Experimental) attaches great importance to enable students to experience and comprehend the concept of Green Chemistry. In the context of the new curriculum, as an important component of the textbook material, whether in present form or in content has a great change. The high schools in Guangxi are also going to use the new textbook. In such a context, based on High School Curriculum Standard Textbook Chemistry which is published by the People's Education Press for greening of chemical experiments in high school chemistry experiment education, the study has a certain degree of theoretical and practical significance. Based on the above analysis we make this topic.This study is combined with the experiment content of High School Curriculum Standard Textbook Chemistry which is published by the People's Education Press to address the principles and strategies of greening of chemical experiments in high school chemical experiment teaching. The purpose of this study is infiltrating the concept of Green Chemistry into the students to enable them to learn how to use Green Chemistry's principles and methods to prevent and control the experimental contamination and set up the concept of Green Chemistry.This study mainly uses the research methods such as literature research method, survey study, natural science research methods. Firstly, the study finds the development and the status quo of Green Chemistry and Green Chemistry Education with literature research method, and then elaborates the significance of this study from sustainable development, the development of chemistry, chemical curriculum reform, quality education, physical and mental health of teachers and students and other aspects. Through classroom observation and questionnaires and interview survey to understand the situation of high school chemistry experiments, we summarize the problem and analyze the reason. Combined with curriculum standard, we analyze the experimental content of High School Curriculum Standard Textbook Chemistry which is published by the People's Education Press with the view of Green Chemistry. Finally, we discuss the principles of greening of chemical experiments of high school, and propose the principal strategies greening of chemical experiments in high school chemical experiment teaching combined with the specific experimental cases and experimental teaching cases.The findings of the study can be stated in brief. (1) Now the greening of high school chemical experiment in a worrying situation, the urgent need for carrying out greening of chemical experiments in high school chemical experiment teaching. (2) Based on statistics and analysis of experiment content in High School Curriculum Standard Textbook Chemistry which is published by the People's Education Press, we find that the experiment content is good at reflecting the ideas of Green Chemistry, but there are still some shortcomings.To deal with these problems, we propose the principles and strategies of greening of chemical experiments in high school chemical experiment teaching. The strategies include: (1) green improvement of experiments, (2) regulating experiment operation, (3) carrying out micro-chemical experiment, (4) green treatment of the "three wastes" in chemical laboratory, (5) chemical experiment teaching combined with computer multimedia.In china, Green Chemistry Education of high school is still in its infancy, and the author's knowledge of its is not enough in-depth,so the research is still relatively superficial. What's more, as the limited of the researcher's theoretical and practical experience, and the research methods and the steps to be perfect, so the study need to be further improved and developed.
