Research On Physical Experiment Questions Of National College Entrance Examination In Recent Six Years

Physical experiment is the foundation of physics teaching,and the development of physics is inseparable from experiment teaching.Physical experiment plays an irreplaceable role in the study of physics,many physical formulas and conclusions are obtained by experiments,and the examination of physical experiment in the college entrance examination is only written test,and there is no way to directly test the experimental operation level of students.Then under the condition of the written examination of college entrance examination physics questions for students' experimental ability to test how,which also has a certain guiding role for the majority of teachers.This paper uses statistical method and case analysis method to conduct statistical analysis on the physical experiment questions of the National College Entrance Examination from 2015 to 2020.This paper mainly carries on from the following three aspects.First of all,the study of the national college entrance examination volume to build the framework of physics experiment,in the high school physics course standard and subject core literacy,on the basis of related literature,and determined from the following six dimensions as a focal point of study is the first elements of scientific inquiry,the second is scientific knowledge,the third is the experimental test,the fourth is the topic design,the fifth is a physical method,the sixth experiment topic proportion of score,and combined with the corresponding sample standard define each dimension analysis.Secondly,the physical experiment questions of the National College Entrance Examination in recent six years are classified and statistically analyzed from the aspects of scientific inquiry elements,scientific knowledge,experimental nature,question type design,physical methods and the proportion of the score of the experimental questions.Finally,combining with several typical cases of physical experiment questions in the recent six years,the characteristics and proposition trends of physical experiment questions in the college entrance examination are illustrated.After research and analysis,this paper draws the following conclusions:(1)In terms of scientific inquiry elements test,analysis and argument papers accounted for about 43%,the experiment topic design experiments and planning papers accounted for about 27%,the experiment topic experiment and collect evidence papers accounted for about 22%,experimental subject assessment papers account for about 4% of total experimental subject,guess and suppose papers accounted for about 3%,the experiment test question papers experiment topic about1% of total;(2)In the experimental questions of the scope of knowledge examination,mechanics and electromagnetism of the examination of the basic half,the test of the basic experimental equipment is less;(3)In terms of the nature of the experiment,measurement test questions accounted for about 44% of the total number of experimental questions,exploration test questions accounted for about 35% of the total number of experimental questions,verification test questions accounted for about 21% of the total number of experimental questions;(4)In terms of experimental questions,the fill-in-the-blank questions are the questions that must be examined in the national physical experiment questions,accounting for 100%,followed by the drawing questions accounting for about 43%,and the multiple choice questions are relatively small,accounting for about35%.Finally,the number of short answer questions is the least,accounting for only about 8 percent.(5)In the aspect of experimental physics method examination,the equivalent method is the experimental method which appears more in the physical experiment questions of college entrance examination,followed by the accumulation method,and the control variable method and trace method appear less in comparison.(6)In terms of experimental test score and proportion test,the total score of the physics experiment in the college entrance examination accounts for 13.6% of the total score of the physics test paper.The score of specific 22 and 23 questions may be6 and 9 points or 5 and 10 points due to the difficulty of the test paper.Generally speaking,there is not much difference in the score of the same question.From the point of view of specific case analysis and research,in the last six years,the physical experiment questions of the national college entrance examination are more and more presented from multiple perspectives.Emphasis should be placed on the extension and exploration of test questions in the elements of scientific inquiry.In terms of scientific content,the innovation of basic experiments should be strengthened and the connection between life scenes should be strengthened.
