Teaching Research On The Principle Of Chemical Reaction Based On The Idea Of Change And Balance

Today,with the rapid development of science and technology,the training of students′ creative thinking and practical application has become an important aspect of subject teaching,and in these aspects,it shows the basic quality of chemistry.It is a kind of quality and core quality that can enable students to have lifelong learning and adapt to social development.The concept of change and balance is a key factor in chemistry,which reflects a special chemical thinking method and a basic concept,and plays a positive role in improving students’ cognitive and emotional ability.The principle of Chemical reaction is an important chemistry course in senior high school,and it is also a very important course.This course pays attention to the cultivation and cultivation of students’ needs for the new era and the new era,and highlights the combination of "change" and "balance",which is conducive to the cultivation and improvement of students’ core literacy in chemistry.For this reason,the subject of "the basic principles of chemical transformation and equilibrium" is discussed in this paper.By reviewing the relevant materials,this paper has studied the current middle school chemistry classroom on the cultivation of students’ change concept and equilibrium consciousness,through the understanding of the meaning of "change and equilibrium thought",this paper has made a comprehensive analysis of the characteristics of the knowledge structure of chemical reaction principles and their quality in the past five years,and has combined these two factors,and has carried on a series of teaching plans.it has constructed the teaching strategies of “Integrating curriculum resources,excavating knowledge intension deeply”,“Creating real situation,promoting the change of learning mode”,“Exerting experimental function,improving subject understanding ability”,“Seeking problem clues,guiding students to explore independently”,“Designing teaching evaluation,realizing teaching evaluation integration”.According to the teaching strategy,this paper designs the teaching case of chemical reaction principle,which trains the students’ changing idea and the balanced thought,and carries out the teaching practice.The results of the teaching practice are as follows:(1)the students’ interest in learning chemical knowledge has been enhanced,and their fear of difficulties in understanding the principles of chemical reaction has been effectively relieved;(2)Students have a deeper understanding of“material change”and a more comprehensive understanding of“Chemical balance”;(3)the transfer ability of students’ chemical knowledge has been improved,and their academic performance has been effectively promoted;(4)the way students cognize chemical knowledge has changed,the chemical core competencies of the idea of change and balance has been cultivated.The paper is divided into four parts:the first part,the research background,objectives and significance,tracking the research status,determine the research methods.The second part,carding research literature,clear research theory,define the concept of research.The third part,in-depth teaching,to find out the existing problems in the teaching of the idea of change and balance,to build a chemical reaction with the characteristics of the principle of knowledge to cultivate students’ concept of change and balanced idea of teaching strategies.The fourth chapter tests the experimental results through experiments,summarizes and summarizes the experimental results,and puts forward the experimental results and experimental results.Research conclusions:(1)to arouse students’ enthusiasm for learning by setting up classroom situations;(2)to change the way of understanding students through experiments and exploration;(3)to promote students’ understanding of students through the combination of teaching and evaluation;(4)to combine learning methods with practice to cultivate students’ basic quality.
