Research On The Influence Of Chemical Model Of Teaching On Junior High School Students’ Chemical Modeling Ability

As a science subject based on natural science,chemistry occupies a very important position in the field of science and technology.At present,not only materials science,life science,environmental science,physical science and other aspects are involved in chemical-related substances and changes in their properties,At the same time,chemistry has become an important core of modern technology.Therefore,chemistry teaching is only very important in the development of science.The model teaching method has become the essential tool of the junior middle school chemistry curriculum standard teaching,so this article revolves around why to carry on the model teaching?What is model teaching?Junior middle school chemistry at present What is the status of model teaching?What are the manifestations and problems of chemistry model teaching in junior high school chemistry class at present?What is the effect of model teaching on students’ academic level?In this paper,literature,investigation and experiment are used to study these five core problems.This paper mainly analyzes the application of chemical model teaching method in junior middle school chemistry.The paper mainly studies the necessity of applying chemical model teaching method in junior middle school chemistry class through the study of chemical model teaching method theory,and through the junior high school.The investigation of the application status of chemical model teaching in chemistry class,focusing on the investigation of the subject of junior high school chemistry class and the understanding of chemical model teaching and the implementation of chemical model teaching;then,the paper analyzes the investigation based on the investigation The expression of chemical model teaching in the junior middle school chemistry class and the existing problems,the performance situation mainly includes the chart model,symbol model?algebraic model and so on in the chemical model;then,this article is fully integrated with the chemical model teaching,in a junior high school The teaching experinent research in the chemistry classroom,through the experimental class of two levels at the same level of learning,through the use of model teaching in the classroom teaching to give the classroom tasks of the experimental class,so that the model teaching can effectively improve the students’ Modeling ideas and modeling capabilities,To design modeling problem scoring significantly higher than students who do not perform teaching model;and in the non-modeling idea or topic score with less thought of modeling,modeling teaching and not teaching model did not differ significantly.Finally,the paper draws on the application of improved chemical model teaching in junior high school chemistry class.The research of this thesis mainly explores the role of the application of modeling ideas in the promotion of junior high school chemistry review,thus improving the trust of teachers and students in modeling thinking and modeling teaching,and improving the application of modeling teaching in junior high school chemistry teaching.Chemistry learning and teacher chemistry teaching provide corresponding reference value.
