A Study And Practice Ofinfiltrating Green Chemistry Education In Senior High School Chemistry Teaching

The problem of environmental pollution caused by the rapid development of industrialization is becoming increasingly serious.People gradually realize that the rapid economic growth must not be promoted at the cost of the environment.Green chemistry and sustainable development are reflected in the new high school chemistry curriculum and high school textbooks.The concept of green chemistry points out the direction for environmental protection and more in line with the concept of beautiful China put forward by general secretary Xi Jinping.Therefore,it is inevitable for green chemistry to enter the field of education.At present,China's green chemistry education is widely used in college chemistry teaching,but how to infiltrate the concept of green chemistry in high school chemistry teaching has relatively few experiences to learn from.Playing the value and function of green chemistry education according to the requirement of the new curriculum reform is a brand new subject in high school chemistry teaching.This study discusses to integrate green chemistry education into senior high school chemistry teaching,explores the related problems of green chemistry education in senior high school chemistry teaching and the teaching strategy of cultivating senior high school students' green chemistry concept and environmental protection awareness,so as to enhance the implementation of green chemistry education in senior high school.First of all,in the form of a questionnaire,the students and teachers in Kaifeng,Zhoukou and Zhengzhou in the first grade of high school were investigated to understand the cognition of green chemistry,experimental treatment and environmental protection behavior of high school students.In terms of teachers,it is necessary to understand their cognition of green chemistry,the status quo of green chemistry education and their attitude towards green chemistry education.The survey results show that currently high school students have a strong interest in learning green chemistry.From the feedback of environmental protection behaviors,generally high school students have a strong sense of environmental protection,but some students need to further improve their green ideas.Green chemistry teaching is popular among students and teachers,but due to the pressure of entering a higher school,the green chemistry material hidden in the textbooks has not been fully explored,and teachers have a weak awareness of infiltrating the green chemistry concept.Secondly,based on the careful analysis to study the domestic and foreign relevant theoretical knowledge and experience of green chemistry education research results,the ordinary high school curriculum standard and are associated with green chemistry required a textbook content,according to the experimental requirements,based on the results of the survey of the green chemistry education found in deficiency,the author constructs the classroom penetration,experimental chemistry history penetration,penetration,extracurricular activities,the teaching strategy of infiltration.Thirdly,according to curriculum standards and textbook requirements,the teaching steps of green chemistry education in senior high school chemistry teaching are discussed to realize the application of teaching strategies in specific teaching links.The practical cases have been worked out taking "Nature and Use of Sulfur Dioxide" and "Ammonia" which highlight environmental protection as examples.Finally,the teaching practice was carried out in Kaifeng A High School.The teaching practice was post-tested in the form of green chemistry special and comprehensive topic.By comparing the results of the experimental class before and after the experiment,the experimental class and the control class,the effectiveness and feasibility of the teaching strategy were clarified.The results show that green chemistry education can cultivate students' interest in chemistry study,establish the consciousness of protecting environment and protecting nature,and effectively improve students' academic performance.This teaching strategy and method is helpful to improve students' scientific literacy,establish the concept of sustainable development,and make contributions to the cultivation of high-quality talents with green consciousness and ability.Meanwhile,it enriches the teaching method of high school chemistry and provides some teaching ideas for high school chemistry teachers.
