The Research Of Yunnan College Entrance Examination Physics Questions In Recent Six Years Based On SOLO Classification Theory

The national college entrance examination is an important examination way for the selection of talents.Therefore,the quantitative analysis of the examination questions can get representative characteristics of the college entrance examination exercises,so as to put forward targeted teaching suggestions for the college entrance examination and promote the development of teaching.SOLO classification theory means observable learning results,and it has strict grading standards and operability for thinking operation in the learning process.Since its birth,SOLO classification theory has been widely used in test question evaluation and teaching research.Based on the SOLO classification theory,a standard scale for grade division was developed.The physics questions of Yunnan province's college entrance examination in recent six years were coded according to the standard scale for grade division.Then,qualitative and quantitative comparative analysis was conducted on the coded data,and then the overall test questions were compared and analyzed.The statistical results of knowledge modules,test difficulty,percentage of points and high-frequency test points of physics in Yunnan college entrance examination in recent six years are as follows:First,Yunnan province in recent six years of college entrance examination physics questions mainly examine the level of the relevant structure.The whole part focuses on mechanics,followed by electromagnetism,and atomic physics.The knowledge topics of mechanics mainly focus on A1(mechanical motion and physical model),A2(interaction and Newton's laws of motion)and A4(mechanical energy).The topics of electromagnetic knowledge mainly focus on B2(circuit)and B3(magnetic field).For the questions involving mechanics and electromagnetism,the most level of SOLO classification is the level of correlation structure,which requires students to think at a medium level.Second,The difficulty of the physics questions in the college entrance Examination of Yunnan province in the past six years shows a trend of decreasing first,then increasing and then leveling off.The overall difficulty is between 2.9 and3.2,with an average difficulty of 3.14935,which is at a medium and low level.Third,After one-way analysis of variance,it is concluded that there are significant differences in the difficulty gradient of the physics questions in yunnan province in recent six years,which can meet the purpose of selecting talents of different levels in the college entrance examination.After the homogeneity of variance test of the other party difference analysis results,it was found that the variance of the proportion of the score values at different SOLO classification levels among the physics exams in yunnan province in the recent six years was homogeneous,that is,there was no significant difference between the physics exams in Yunnan Province in the recent six years.It can be seen that the overall difficulty of physics examination questions in yunnan province in recent six years is at a relatively stable level,and there is no sudden change in difficulty.Fourth,Taking the subjects of multiple choice questions,experimental questions and calculation questions of the physics examination questions in Yunnan province in recent six years as the statistical basis,comparative analysis is made and found that: The topics with the highest frequency of examination were A2(interaction and Newton's laws of motion),A3(throwing body motion and circular motion),A4(mechanical energy),A6(law of universal gravitation)in mechanics and B3(magnetic field)and B4(electromagnetic induction)in electromagnetism,with a frequency of 100% in 6 years.Finally,the "large unit" teaching mode is proposed for SOLO classification level in multi-point structure level knowledge points,and the "reverse" teaching exercise lesson teaching idea is proposed for SOLO classification level in correlation structure level,expanding abstract structure level.
