The Research On The Connection Of Chemistry Knowledge Between Junior Middle School And High School And It's Teaching Strategies

Since I was engaged in high school chemistry teaching,I have found a phenomenon,that is,the students with good chemistry scores in junior high school are not particularly good after high school,and their enthusiasm for chemistry learning is greatly reduced.I think the main reason is that in the process of junior high school into senior high school,teachers did not do a good job in the connection of chemical knowledge,junior high school knowledge is very basic,more close to life,senior high school knowledge is more disciplinary,more difficult.This causes students to feel at a loss for the knowledge of high school,and also increases the difficulty of teaching chemistry teachers in high school.Therefore,in the context of new curriculum education,the author expounds and studies the above problems.Most of the chemistry knowledge in senior high school is based on junior high school chemistry.Compared with junior high school,the difficulty has been greatly improved.Therefore,in the process of students' chemistry learning,teachers need to compare the teaching materials of junior and senior high schools,find out the place of convergence for sublimation,and then put forward more useful and effective convergence teaching strategies,which is the content of this paper.This paper mainly includes literature analysis,case analysis and questionnaire.The paper is divided into six chaptersThe first chapter is the introduction.It mainly includes:background of topic selection,research progress at home and abroad,research purpose and significance,research content and methods.The second chapter is the core concept and theoretical basis.It includes the concepts of chemistry knowledge,cohesion and teaching strategy.This paper is based on the theory of constructivism learning,recent development zone and knowledge transfer.The third chapter is the cohesion analysis of chemistry knowledge in junior and senior high school.The chemistry teaching materials of junior and senior high schools were compared,and the core knowledge was selected,including five parts:redox reaction,metal and its compounds.This paper studies the presentation and cohesion of these five parts of knowledge in textbooks,and summarizes the cohesion characteristics of each part of the content.The fourth chapter is the teaching strategy of the connection of chemistry knowledge in junior and senior high school.Eight teaching strategies are put forward from three aspects of curriculum content,teachers' teaching method and students'learning method:one is to fully explore the content of chemistry teaching materials in junior and senior high schools;the other is to pay attention to the connection between new and old knowledge;the third is to attach importance to experimental teaching;the fourth is to assist macro and micro teaching with technical means;the fifth is to connect with nearby chemistry for teaching;the sixth is to teach in problem situation to cultivate students' thinking ability;the seventh is to learn The eighth is to establish thinking map and form knowledge network.The fifth chapter is the case design and practice of the connection of chemistry knowledge between junior high school and senior high school.According to the proposed teaching strategy for teaching practice,and analysis of the results.The sixth chapter is the research conclusion and prospect.
