Analysis Of Chemistry Test Questions In 2021 National College Entrance Examination Based On Subject Core Accomplishment

With the official proposal of the core literacy in the "General High School Chemistry Curriculum Standards" of 2017 Edition,it means the starting of the new college entrance examination reform by the general high school curriculum standards.What the experts and scholars have focused on is the research on the proposition of the college entrance examination.The main research and teaching direction of front-line teachers lie in how to strengthen the core literacy examination of disciplines.The research of this thesis aims at analyzing the examination method or performance form of core literacy in the 2021 college entrance examination chemistry test questions,how to achieve the echo of discipline knowledge and practical application,and how to focus on the cultivation of students’ comprehensive ability and core literacy while comprehensively examining students’ basic knowledge level.The methods such as literature research,comparative research,statistical analysis and so on are adopted in this thesis to conduct a comprehensive analysis on the2021 college entrance examination national paper chemistry questions by taking the five core literacy as the starting point.According to the analysis results,it indicates that the proportions of the national A and B chemistry test questions for the core literacy "evidence reasoning and model cognition" account for 31% and 30% respectively.The examination proportion of "macro identification and micro analysis" of core literacy in A and B chemistry test questions accounts for 22% and 26% respectively.The examination proportion of "change concept and balance thought" in A and B chemistry test questions accounts for 17% and 18% respectively.The examination proportion of the core literacy "scientific exploration and innovation consciousness" in the A and B chemistry test questions accounts for 18% and 17% respectively.The examination proportion of the core literacy "scientific attitude and social responsibility" in the A and B chemistry test questions accounts for 12% and 9% respectively.Based on analysis of chemical tests a and b roll core literacy test in five disciplines are very seriously,determined to carry out the fundamental task of khalid ents,pay attention to subject core quality oriented,focus on essential knowledge and key ability,reflect the reform of college entrance examination content,at the same time,pay attention to students all-round development as the objective,material selection situation proposition as the carrier,It fully embodies the new situation of teaching and educating people with equal emphasis on quality and knowledge,ability and moral accomplishment.Based on the analysis of the national chemistry examination questions in the national college entrance examination,this paper puts forward the cultivation strategies of strengthening the core literacy of chemistry in the conventional teaching: paying attention to the core concept teaching and the triple representation teaching,and enhancing the ability of macro identification and micro analysis.Analyze examples,sort out the knowledge framework,pay attention to chemical changes,and cultivate the idea of balance.Combined with model structure,improve knowledge system,stimulate students to develop thinking construction,and train their evidential reasoning and model cognitive ability.Reflect the importance of experimental content in teaching materials,improve the learning environment,provide a variety of choices,strengthen the awareness of scientific inquiry and innovation.Pay attention to subject hot spot,strengthen social practice,establish scientific attitude,strengthen social responsibility.The analysis on the 2021 national college entrance examination chemistry questions(A and B)is carried out from the perspective of the core literacy of the discipline.However,the analysis results may be one-sided because of the limited knowledge reserve and ability level of the author.In future teaching practice,I hope to continue to pay attention to and value the importance of discipline core literacy in knowledge transfer.
