Research On The Teaching Practice Of Cultivating The Concept Of Green Chemistry For Senior High School Students Under The New Curriculum Standard

As a new concept of preventing and controlling pollution from the source,green chemistry is conducive to environmental protection and social development.Under the situation of advocating the construction of ecological civilization,green chemistry has become a new direction of chemical development.China's green chemistry education has gradually penetrated into middle school chemistry teaching.In 2017 the New Curriculum Standards proposed new requirements on green chemistry,the concept of sustainable development and the sense of social responsibility.Therefore,how to cultivate high school students' green chemistry concept has evolved as a crucial concern for teachers in the middle school.This thesis is divided into the following five parts.The first part includes the research background,the research status of green chemistry at home and abroad,and introduces the research contents,ideas and significance.The second part covers the meaning and core contents of green chemistry,analyzes the new People's education press high school chemistry curriculum standards and People's education press compulsory teaching materials,and clarifies the contents and requirements of green chemistry teaching.The third part surveys the level of green chemistry ideas of high school students through questionnaires,and then statistics and analyzes the results of the questionnaire results and draws research enlightenment to further clarify the importance of cultivating high school students' green chemistry concept.According to the analysis of People's education press high school chemistry textbook and the New Curriculum Standards,the fourth part takes the first lesson of "ammonia nitric acid and sulfuric acid" in the third section of People's education press Chapter 4 as an example to design the green chemistry teaching plan,and conducts the practical teaching and the evaluation of teaching effect.The fifth part conducts a summary of the shortcomings and practical problems of this research and proposes the research direction.
