Research And Practice Of Chemistry Teaching In Senior High School Based On The Concept Of Green Chemistry

With the development of the society,the deteriorating environmental problems are affecting human survival and development,in order to solve this problem,"green chemistry" arises at the historic moment,the term originated in the United States,developing countries around the world,is deep the support and advocation of governments and chemical workers,it is a new concept of preventing and controling of pollution from the source.With the vigorous development of the green chemistry and green chemistry education in our country are widely used in the university teaching,gradually penetrating into the chemistry teaching of middle school.About how to penetrate green chemistry idea in middle school chemistry teaching,there is few experience that teachers can draw lessons from,which is a huge challenge for middle school chemistry teacher.This paper is divided into six parts:The first part is the introduction,which includes the background and significance of the research,the purpose,content and thinking of the research,and the research actualities of green chemistry at home and abroad.The second part is the theoretical basis of the research,this part includes the meaning and principles of green chemistry,chemistry curriculum standards for high schools for the formation requirements of the concept of green chemistry and teaching material analysis.The third part researches the concept of green chemistry of the teachers and students,which includes the questionnaire investigation of high school students' concept of green chemistry,and interviews of high school chemistry teachers' concept of green chemistry,then statistics the questionnaire and the interview's results to come to decisions.The fourth part is the strategy research of permeating the green chemistry concept in high school chemistry class,which includes the traditional and innovative infiltration strategy.The fifth part is the practical research on the permeation of green chemistry concept in high school chemistry class,which includes the design of research scheme,implementation of teaching process and evaluation of teaching effect.The sixth part is the research conclusion and outlook,which includes the conclusion of this study,the reflection of deficiencies and the prospect of future research.The questionnaire and interview results show that the green chemistry concept of high school students is weak,and the teachers are not paying attention to the infiltration teaching of green chemistry.The practical teaching results show that the teaching strategy is effective.Students' interest in learning has been enhanced,forming a good green ideology and social responsibility.
