Misunderstanding Of Chemistry Teaching In Middle School:Causes And Countermeasures

With the development of human society and economic level,information technology has been widely used in all walks of life,such as education and teaching.Teachers' teaching takes great advantages as well as some drawbacks form Internet.Ag great many network data herein elucidate the relationship of the concentrations of the electrolyte solution particles,including some unscientific data,which may be directly passed on to the students without suitable correction and led to much misunderstanding in teaching.Therefore,it is necessary to study the teaching errors of the relationship among the concentration of the electrolyte solution particles,which would lead to analyze the causes,propose corresponding countermeasures and apply them in teaching.This paper is based on the literature research method combined with questionnaire survey,interviews and computer-aided methods to conduct research.First of all,through reviewing and collating a large number of related literatures,a comprehensive analysis of the current research status of the relationship between the concentration of electrolyte solution particles at home and abroad is carried out,and meanwhile the importance and necessity of this study are described.Then,the theoretical basis of the research,defines the related concepts,interviews with teachers and conducts questionnaires to students are conducted with aim to understand the teaching situation of particle concentration relationship of electrolyte solutions.Finally,according to the results,combined with literature research,the teaching errors and their causes in the concentration of electrolyte solution particles were determined with corresponding countermeasures.According to the idea of countermeasures,the electrolyte solution was classified and the formulas for calculating the concentration of each particle in the various electrolytic solutions were drawn,and the diagrams of the particle concentration of some common electrolyte solutions were plotted,which would provide materials for teaching.Finally,based on these teaching materials,we designed a teaching program to deal with the misunderstanding of the relationship between the concentrations of electrolyte solution particles so as to improve teaching.Six chapters are used to explain the causes and countermeasures of the teaching errors of the relationship between the concentrations of the electrolyte solution particles.In the preface of the first chapter,the research background,research status at home and abroad,research purpose,research significance and research methods are introduced.The second chapter explains the four theoretical bases and three related concepts of this study.The third chapter investigates and analyzes the teaching and learning status of the relationship between the concentrations of electrolyte solution particles.The fourth chapter makes an analysis on the causes of electrolyte solution particle concentration and the teaching conditions to solve teaching errors required,and then determine the corresponding countermeasures,and the calculated size of electrolyte concentration and drawing particle concentration diagram to explain.The fifth chapter is the teaching material arranged in this study,which is selectively applied to the teaching design,and the teaching reflection is carried out.The sixth chapter is the summary and prospect of this study.Based on the summary of the whole research topic,it points out the innovative points and deficiencies of the research,and puts forward the outlook for the future.In conclusion,we hope to provide new idea for chemical researchers as well as provide some teaching materials for high school chemistry teachers to deal with the misunderstanding of the relationship between electrolyte concentration via this study.
