Analysis And Countermeasure Of The Concept Of Permeable Green Chemistry In Middle School Chemistry Teaching

With the improvement of the level of economic development,people's pursuit of a happy and good life has been on the rise,and at the same time,there are new requirements for the living environment.Green chemistry is also known as "environmentally friendly chemistry","clean chemistry",its purpose is to eliminate pollution fundamentally,it is characterized by the beginning of the use of scientific means to prevent pollution,so the process and terminal are zero emissions or zero pollution.Green chemistry is not only a discipline,but also an environmentally friendly concept of life.Middle school is an important stage of forming personal primary values,high school chemistry education in the critical period to the penetration of the concept of green chemistry in student,this can not only cultivate students learning interest in green chemistry,form the consciousness of protecting the environment,improve chemical core literacy for middle school students,and to boost our country to improve environment and promote sustainable development of our country citizen concept has an indelible important meaning to improve.Since green chemistry has been developed in recent years,the penetration of green chemistry concept in middle schools under traditional chemistry education has yet to be investigated.Through literature research,questionnaire survey,interview and other methods,this paper investigated three middle schools in Y city,analyzed the status quo of the concept of permeating green chemistry from both teachers and students,and found the reasons affecting the concept of permeating green chemistry.(2)a single channel for learning green chemistry.(3)there are limited opportunities for experimental operation,and there are certain limitations in the idea of permeating green chemistry through experiments.(4)fail to integrate the concept of green chemistry into daily life;The main problem among teachers is(1)different teachers attach different importance to green chemistry education.(2)teachers' experience limits the penetration of green chemistry concept.(3)limited teaching conditions affect the penetration of the concept of green chemistry.In order to actively permeate the concept of green chemistry,this paper puts forward the countermeasures of permeating the concept of green chemistry by referring to relevant literature and combining with the actual situation.In the process of research strategies,through the collection of the literature found that,although many scholars have put forward some advice on green chemistry education,but there is no detailed analysis to the teaching material,nor for the teaching material of the green chemistry knowledge involved in the detailed teaching advice,so based on the study of countermeasures to fully summarizes the teaching materials of green chemical knowledge,and summarized the detailed contact actual situation teaching Suggestions.Finally,the countermeasures are drawn :(1)the concept of green chemistry is purposefully permeated in daily classroom teaching.Firstly,teachers should improve their ideological understanding.In the course of lesson preparation,they should strengthen their understanding of green chemistry by continuing to learn.They should grasp the teaching materials and use them reasonably to permeate the green chemistry concept.(2)permeate the concept of green chemistry in chemical experiments(exploration experiments and demonstration experiments).The concept of green chemistry is permeated from the aspects of experimental principle,design of experimental equipment and disposal of laboratory waste.(3)permeate the concept of chemistry in practice activities,and let students learn green chemistry through practice activities;(4)using the concept of green chemistry in daily life,teachers are in the process of classroom teaching more contact with students' real life,let the students can apply green chemical concept to daily life,such as green chemistry advocate saving,no pollution,save water and electricity in our daily life,the living garbage classification,green travel,and so on.
