The Exploration Of The Misconception In Chemical Equilibrium Shift

“Chemical equilibrium”is one of the core concepts of high school chemistry conceptual system,which is the basis for studying ionization equilibrium and sedimentation equilibrium.This part of the content is complicated and has a certain degree of abstraction,students often have a lot of misunderstanding in the related learning.Among them,the chemical equilibrium shift is the integrated use of chemical equilibrium,but also the most difficult part of the students are learning in chemical equilibrium in the learning process,there are many misconceptions of students in this part of the learning process.On the basis of the analysis of the new chemistry curriculum standard for senior high school and senior high school chemistry textbook on the basis of chemical characterization and transformation from the three perspective of compiling two section chemical equilibrium shift test.A survey of 142 high school students in a middle school in Ningbo area was conducted to explore the myth of the students' chemical equilibrium shift.And the results of the survey from the dimensions of the representation of the conversion,the content of the different dimensions and different types of comparative analysis,in-depth exploration of the reasons for the misconception of students.Through the analysis of senior high school students from learning in the “chemical equilibrium shift” misconceptions,and analyze the causes of misconceptions,from the aspects of the use of textbooks,teachers and teaching resources of "chemical equilibrium shift" teaching to put forward the following suggestions: Firstly,we should add the corresponding explanation of the micro graphic and symbolic representation corresponding to the macro representation.Second,clear the effect of temperature,concentration and pressure on the balance and the relationship between the three.Third,using a variety of questions,to enhance the diversity of students' ability to express.Fourth,enrich the multimedia visualization tools to strengthen the students' understanding of the “chemical equilibrium shift”.
