The Preliminary Research On Greening Of Chemical Experiments In High School Of The People’s Press

In twentieth Century, the degree of pollution of the earth is gradually deepen, the environmental problems of the world are becoming more and more obvious. Based on the background Green chemistry emerges as the times require, it is possible to reduce the emission of pollutants by using modern science and technology, the human survival environment can be cleaner, the aim is to generate the emission of pollutants from the source to avoid. Green chemistry can represent the future trend of development of chemistry and direction, have the vital significance to the survival and development of human beings. With the improvement of environmental quality, the green chemistry research attract more and more attention all over the world.Compared with the former Peple’s Educationg Press of text books,the new ones have great change both in presents fomer and in content.. The newly-formulated Chemistry standard of high school pay more attention to the function of chemical experiments.By means of concrete chemical experiment,Students can experience and comprehend thought and conscious of greeng Chemistry, which is one important aims of chemical expriments in high school.The expriment content is more suitable for Student’s life and the present pattern is more reasonable, the final purpose is to forter student’s sense of social responsibility and scientific literacy.The implementation of goals of Green Chemisty needs from generation to generation green talents who understangd green knowledge and technology, have green chemical thinking.The training of Green talents requires green chemical education.The high school education is the most important in one’s study life.The impletation Green chemical education has positive and realistic meaning to students, which is propitious to form environmentai awareness and sustainable development of them.This study mainly uses the research methods such as literature method、 questionnaire survey、observational methods.In the first place this article has introduced the genesis and seed time of green chemistry, the development and the status of geeen chemistry and green chemistry education at home and abroad.; and then expounds the sense of realizing greening of chemical experiments in high school from sustainable development,the idea of STS,the development of chemistry, physical and mental of teachers and students and other aspects。 United with curriculum standard,we analyse the exprimentan content of 《High School Curriculum Standard Textbook Chmistry》,which ispublished by the People’s Education Press, invagate the situation of senior school chemistry expriments and analyze the reason.At length,the article discuss the principles of chemical expriments,and give concrete measures chemical expriments in high school.The author list one specific experimental teaching cases at the end of the paper.Conclusions:(1) Chemical experiments in the new testbooks which is published by the People’s Education Press is good at embodying the ideas of Green chemistry,however, there are still many improvements.(2)At present, it is impacted by the subjective factors and objectives factors,"three wastes" of chemical laboratory in high school.do harms to enviroment seriously。 Carrying out greening of chemical experiments in high school is in extreme urgent situation.(3) Chemical experiments in high school is system,various factor affect each other,we should use the systematic engineering method to realize greening of chemical expriments in high school.The strategies of realizing greening of chemical expriments in high school can be summarizedas follows:(1) green improment of experiments (2)standardization of experimental operation (3) extengding micro-chemical experiment.(4)green treatment of the "the wastes" of chemical laboratory (5)combing chemical experimental teaching with computer multimedia.Green chemistry experiment in high School of our country is still at the primary stage,More productive and systematic theories and practices are needed, the research level of author is limited, the green chemical experiments in senior high school is not profound, understanding and action possible deviations, further examination of the results have to be practical, expect to play a valuable role.
