Research On Progressions & Development Of Electronic Conservation Thought In Different Learning Sections Of High School Chemistry Study

Conservation thinking is one of the most important thinking in chemistry.Testing tools for the law of conservation are common,and such questions often appear in the college entrance examination,such as 2019 national paper III 28(4).But the formation of conservation thinking is not built directly,it needs to be in the process of high school chemistry teachers teaching and students learning.With continuous infiltration,students gradually develop and use conservation thinking to solve more complex chemical problems.Different grades refer to different grades,which are mainly compulsory and elective.The purpose of this study is to test the application of conservation of gain and loss by electricity in different levels of high school chemistry,including oxidation-reduction reaction,metals and their compounds,non-metals and their compounds.Also,to evaluate the learning progress of different groups of students in senior grade one & two,and the difference between male and female students in the same period.The conclusions are as follows:(1)The students in senior one have better ability of grasping the concept of electronic conservation and reasoning than grasping calculating;(2)The advanced mastery of electronic conservation of boys in senior one is better than that of girls,and there is little difference in the mastery of electronic conservation thought between male and female students in senior two.(3)With the progress of study,students have a better understanding of electronic conservation;the four levels of conservation are understood more and more deeply.At last,this paper summarize the importance and methods of cultivating this thought in the process of new lesson teaching.
