The Practical Research On The Inquiry Activity Of Junior Middle School Chemistry Experiment

Chemistry is a subject based on experimental inquiry,and experimental inquiry activity is an important part of chemical experiment,which can promote the all-round development of students.There are still many problems in the current junior middle school chemistry experiment exploration activities.For example,some schools have incomplete chemistry laboratory conditions;some parents do not approve of experiment exploration activities;some teachers still use the traditional chemistry experiment teaching mode because of their outdated teaching ideas.This paper takes "experimental inquiry activity" as the main line to carry out practical research,and adopts constructivism learning theory,dialectical materialism theory,Dewey's activity teaching theory and Bruner's cognitive discovery theory as the powerful theoretical support to carry out practical research in junior middle school chemistry experiment teaching,and guides practice with theory.Through the comparative practical analysis of two parallel classes,the necessity,feasibility and effectiveness of carrying out experimental inquiry activities in junior middle school chemistry teaching are verified,so as to accumulate preliminary experience for junior middle school chemistry teachers to organize and carry out experimental inquiry activities in chemistry experiment teaching.The first chapter briefly describes the research background,purpose and significance.On the basis of collecting and consulting a large number of related documents,this paper analyzes the existing research results in related subject areas.Then explain the domestic and foreign related research situation,clarify the theoretical basis of the subject research,and define the core concepts.Finally,determine the research object,research content and research method.The second chapter investigates the teaching status of junior middle school chemistry experiment inquiry activities and analyzes the main problems.Through student questionnaire surveys and chemistry teacher interviews,after collecting and sorting out the answers,combined with the data to analyze and summarize the existing problems.The third chapter formulates related solutions and shows practical teaching cases.In view of the existing problems,formulate relevant solutions and apply examples to verify them in teaching practice.The fourth chapter analyzes the effect of practical teaching.Through student interviews and comparative analysis of academic performance,classroom participation,and extracurricular performance among students in experimental and control classes,the effectiveness of the program is verified and conclusions are drawn.The fifth chapter gives the research conclusion and prospect.Generalization and summarization,briefly describe the shortcomings of this paper and put forward expectation for the follow-up research on this topic.
