| The needs of human dominate the direction of chemical development,and with the increasing deterioration of the global environment,a new concept of "green chemistry" arises at the historic moment.In the 1990 s,the United States first proposed the term of "green chemistry",which advocated that it can eliminate the pollution from the source,high synthesis and low emissions,and all of the advantages make green chemistry get wide eyes and support from the governments and scholars.our country’s green chemistry education also have started to develop from university to middle school.but In the absence of ready-made experience,how to carry out green chemistry teaching in secondary school is a challenge to high school chemistry teacher.This topic through to the high student’s green chemistry knowledge understanding situation on Chad study found: freshman in existence for green chemistry knowledge narrow channel,the green chemical knowledge is poor,environmental protection consciousness is not strong,green,low carbon habits not well formed,using green chemistry knowledge solution actual problem ability is weak wait for a phenomenon;After the interviews with the chemistry teacher,teachers found that the main problems are: not enough knowledge on green chemistry,the teaching materials of green chemical material value,utilization rate is not high enough,the cultivation of student’s green chemistry concept and habit is less,single teaching methods,the new curriculum idea is difficult to convert to the actual teaching behavior,takes an exam the education purpose is very clear.At the same time also found that teachers’ teaching strategies and teaching attitude is influence of the concept of green chemistry and habits of students.In order to better use this article to build the green chemistry teaching strategies applied to high school chemistry teaching practice,this topic used the action research method,and in class,practice and experiment,inquiry learning,extracurricular activities for the platform to implement the teaching research,and the result of the action research data and materials were analyzed,and the results show that this topic of green chemistry teaching strategy is effective.The Purpose of green chemistry is that it can prevent pollution from the beginning rather than controlling pollution from the end,and we should meet the actual situation in Middle School Chemistry Teaching.I finished this research following this idea.In the first chapter of this article,it describes the green chemistry’s origin,meaning and principle,introducing the research situation on this subject from home and abroad.In the second chapter of this article,it analyzes the meaning of green chemistry and the survey of current situation in high school chemistry teaching.it also has a questionnaire about some chemistry teachers and students from a few part of the middle school of the Lushan county of PingDingShan city,and through this questionnaire we know how the teachers and students master the green chemistry and the reasons for this result.In the third chapter,I Propose and carry out several strategies about green chemistry teaching in senior high school and after these strategies,I think that it is effective.In the fourth chapter,I analyze the teaching effect of this year according to the exam questions from students,the experience of talking with students and some physical objects collected.Finally in the fifth chapter,I reflect on the deficiency of the research,and put forward the prospect of this subject,hope more learners to focus on this topic,hope this topic can be more mature. |
