The Cultivation Investigation And Research On The Current Situation Of Particle Concept In Junior Middle School Chemistry Teaching

This paper mainly investigates the current situation of the cultivation of microparticle view in junior middle school chemistry teaching,in order to understand the influencing factors of the cultivation of microparticle view in junior middle school chemistry teaching,and lay a solid foundation for improving the effect of the cultivation of microparticle view in junior middle school chemistry and the professional quality level of chemistry teachers themselves.This paper includes the following five parts:The first chapter is the introduction of this paper.This paper mainly introduces the background of this topic,the purpose and significance of the research,the research content,the research ideas and framework.The second chapter is the theoretical basis of this paper.This paper mainly discusses the connotation and characteristics of the basic concept of chemistry,the connotation and characteristics of the concept of microparticle,and discusses the influencing factors of the cultivation of the basic concept of chemistry from the aspects of teachers,schools and students.In the third chapter,under the guidance of the second chapter,the current situation of the cultivation of particle concept in junior high school chemistry teaching is investigated.The content dimension of the problem survey is determined,and the corresponding questionnaire is prepared.The selection of the survey sample and the process of the implementation of the questionnaire are explained.The fourth chapter mainly uses SPSS statistical software to process and analyze the questionnaire data.It mainly includes the investigation data processing results of the training effect of microparticle view,students’ learning and teachers’ teaching,and analyzes and discusses these processing results.The fifth chapter summarizes the main conclusions of this research,puts forward some suggestions on the training strategy of junior high school particle concept,and reflects on the main problems in the research.
