| In our country,the college entrance examination is the only way for thousands of students to go to colleges.The college entrance examination is extremely important for every student and even every family.With the announcement of the revision of the 2017 exam outline,The elective 3-5 of the physics subject becomes a compulsory module,and the 2-2 module is deleted.This makes the physical examination papers of the college entrance examination changed again,the biggest change of which should be the calculation part.Elective calculation questions from three to two,and the momentum knowledge of elective 3-5 is also highly likely to be examined in the compulsory calculation part.In the examination of physical examination papers for college entrance examination,the most can test the examinee ability is the physical calculation part,the five abilities required for the examination outline are examined in varying degrees.Besides,the score of physical calculation is large,the scoring rate is low,and it is difficult to solve.Therefore,the importance of the research on the physical calculation questions of the college entrance examination is self-evident.This paper mainly adopts mathematical statistics,literature research and comparative analysis to do the following research on the physics calculation of college entrance examination:(1)Compare and analyze the changes of the examination outline in the last five years before and after the revision of the exam outline,in order to understand the trend of the change of knowledge points in calculation part.By comparison,the exam outline of 2013-2015 has not changed significantly,and the outline of the exam in2016 and 2017 has changed significantly from the previous years.In 2016,the scope of adjustment is larger,which can be said to be the prelude to the change of the exam outline.When the exam outline revised in 2017,the 2-2 module is deleted,and the elective 3-5 of the physics subject becomes a compulsory module.(2)Count the knowledge points and the occurrence frequency of the calculation part in the college entrance examination of the volume I and the volume II before and after the exam outline changes from 2013 to 2017,in order to understand the propositional characteristics of the physical calculation questions in the college entrance examination.Through the study,it is found that: the compulsory question 24 mainly examines the knowledge of "force and movement",the question 25 mainly examines the knowledge of "electromagnetics".The elective question 33(2)mainly examines the state equation of ideal gas in Boyle’s law,Gay lussac’s law and Charlie’slaw,the elective 34(2)mainly examines the refraction of light,the law of reflection,and the examination of mechanical vibration and mechanical wave,the 35(2)before the revision is mainly the examination of the knowledge of momentum.(3)Based on the analysis of the physical calculation of the college entrance examination from 2013 to 2017,summarize the characteristics and features of the physical calculation questions of college entrance examination in past years.(4)Based on the research of the college entrance examination physical calculation question,combined with the current physical classroom teaching situation.This paper discusses the enlightenment to physical teaching in senior middle school,and combines with the change of the examination outline,gives teaching suggestions of the elective 3-5.It is hoped that this study can help teachers and students to know more about the knowledge and test characteristics of college physics calculation questions in recent years,provide references for teachers in physical calculation teaching and lay a foundation for training students’ calculating ability. |
