Research On The Concept Teaching Strategy Of Chemistry In Senior High School Under The Combination Of Macro And Micro Literacy

The development of society,the progress of science and technology,the strength of the country depends on talents,the most important thing to train talents is to improve their quality.Our country has made clear the core quality that the student development needs to have,this is the quality that every student must have,it is the foundation that grows into the person of lifelong development.The core accomplishment of chemistry is the embodiment of the education value of chemistry."Macroscopic analysis and microscopic identification" is the basis of chemistry core accomplishment.Conceptual knowledge is an important carrier of students' development accomplishment.In order to identify and analyze matter from the macro level and micro level,and to describe matter in a specific form,it is necessary to integrate macro level with micro level and chemical concept.Therefore,it is particularly important to carry out the research on the teaching strategy of chemistry concept to improve the quality of chemistry teaching and promote the formation of "macro-micro combination" accomplishment.On the basis of summarizing the research background,significance and method,this paper expounds the research concept,and tracks the research status of "macro-micro combination" accomplishment and chemistry concept teaching.The existing problems in chemistry concept teaching are investigated and analyzed,and the characteristics of chemistry concept learning in senior high school are analyzed.This paper explores the theoretical support of chemical concept teaching and constructs the teaching strategies that accord with the law of concept learning.According to the teaching strategy,the teaching cases of typical concepts are designed and the practice of concept teaching is carried out.Through the analysis of practice results,the teaching practice results are obtained: the students' "macro-micro" thinking is improved;Students' "macro and micro combination" quality has been developed.The Suggestions for the implementation of teaching strategies are: to stimulate thinking in the context;Constructing chemical concepts in problems;Master learning methods in construction;Stimulate students' curiosity in the experiment.The paper is divided into four parts:The first part discusses the research background,purpose and significance,and design research ideas.The second part is to sort out the relevant literature,track the relevant research and define the research concept.The third part analyzes the problem of concept teaching and constructs the teaching strategy according to the teaching theory.The fourth part,carry on the teaching practice,carries on the practice summary,obtains the implementation suggestion.To improve the quality of chemistry concept teaching,teaching strategies corresponding to the concept connotation are needed.The teaching strategies of "creating problem situation,stimulating cognitive perception","providing guidance materials,trying to understand the concept","setting contrast experiments,distinguishing and analyzing chemistry concept" are constructed,which are in line with the characteristics of chemistry concept learning.Teachers are required to carry out teaching design according to local conditions,select appropriate teaching strategies,carry out reasonable teaching design,launch the teaching process generative,implement the "macro and micro combination" of chemical concept teaching strategy,help students to construct conceptual knowledge,develop chemical thinking,and cultivate the core quality of chemistry.
