Analysis Of Calculation Questions In National Physics Paper Of College Entrance Examination In The Past Ten Years

The research of college entrance examination questions is an important task for every educator and front-line teacher.The national examination questions are national examination papers,which are important and representative.At the same time,calculation questions occupy an important position in the college entrance examination physics,and they are also used to examine students' comprehensive analysis and problem solving.An important part of ability.This article mainly uses the literature research method to study the domestic research content and process,defines the two concepts of physical model and mathematical thinking and determines their classification standards,takes "Curriculum Standards" and "Examination Outline" as important documents,and then discusses the research content Using text analysis method and statistical analysis method,52 compulsory calculation questions in the National Physics Paper of the National College Entrance Examination from 2011 to 2020 are used for research.First of all,based on the college entrance examination physics exam syllabus,a statistical analysis of its score changes,knowledge points examined,physics knowledge sections and textbooks to which it belongs,it is found that the scores of calculation questions have not changed much in the past ten years,and the knowledge examined Mainly mechanics and electromagnetism,the textbooks involved are mainly compulsory one,compulsory two,elective 3-1 and elective 3-5.Secondly,the task situation in the research topic,from the source of the situational materials,the degree of combination of the problem and the task situation,and the level of the situation to the students' examination,52 calculation questions,a total of 104 questions,are textually analyzed,and it is found that the situational materials are mainly It is derived from science and technology,social life,and subject knowledge;the combination of situation and problem is better,mainly combined and embedded;situation has a higher level of examination for students,mainly for the extraction of key information,analysis,processing and application of the situation.Third,analyze the physical models according to their classification,and analyze the characteristics of the physical models with a higher frequency;from the perspective of mathematical thinking and methods,statistical analysis of the mathematical thinking and methods involved.Based on the above analysis conclusions and problem-solving methods,the main ideas and methods of problem-solving are as follows: determine the object model,condition model,process model and state model in order to obtain mathematical laws.Finally,according to the classification of mechanics and electromagnetism,the representative real questions are analyzed with examples.Finally,based on the above four aspects of research conclusions and summarizing teaching enlightenment,teachers need to focus on cultivating the following abilities of students:(1)lay a solid foundation and construct a physical knowledge system;(2)cultivate the ability to solve problems using physical models;(3)Cultivate students' abstract thinking and comprehensive application ability;(4)Cultivate students' comprehensive application ability;(5)Standardize students' problem-solving process.
