The Preliminary Comprehensive Difficulty Analysis Of The National College Entrance Examination Mathematics Test

National College Entrance Examination Mathematics Volume II has covered Qinghai,Gansu,Inner Mongolia,Heilongjiang,Jilin,Liaoning,N ingxia,Xinjiang,Tibet,Shanxi,Chongqing,Hainan and other provinces,so it is of great significance to evaluate the difficulty of National College Entrance Examination Mathematics Volume II(Science)questions.O n the basis of Shao Zhifang's CTA and Bao Jiansheng's comprehensive difficulty evaluation framework,this paper presents the concept of comprehensive difficulty in advance,and constructs a comprehensive difficulty evaluation framework with operation level,reasoning level,knowledge level,cognitive level,background level and thinking mode as evaluation indicators.In this paper,the framework of comprehensive difficulty evaluation is used to evaluate the comprehensive difficulty of the mathematics test questions of the National College Entrance Examination Volume II(Science)in 2013-2018.It is verified that the framework has high consistency and reliability.The collected data are analyzed and analyzed by mathematical statistics.The following main conclusions are drawn:(1)In the National College Entrance Examination Mathematics Volume II(Science)from 2013 to 2018,the subjects with the highest comprehensive difficulty value in advance are all the 21 questions(Functions and Derivatives).The subjects with the lowest comprehensive difficulty value in advance appear in the first few questions of the choice questions or the fil ing-in questions.(2)In the National College Entrance Examination of Mathematics Volume II(Li)from 2013 to 2018,the examination degree of operation level and reasoning level is relatively high among the six indicators,while the examination degree of background level is relatively low among the six indicators.(3)In time series,the comprehensive difficulty ranking of National College Entrance Examination Mathematics Volume II(Science)is 2016 > 2017 > 2015 = 2018 > 2013 > 2014.(4)The stability test of each index and the overall difficulty of the National College Entrance Examinatio n Mathematics Volume II(Rationality)from 2013 to 2018 is carried out by using the inverse sequence test method.The results show that the comprehensive difficulty of the National College Entrance Examination Mathematics Volume II(Rationality)from 2013 to 2018 is stable.(5)By using SPSS19.0,the regression analysis of each index of the comprehensive difficulty in advance and the difficulty after the event is carried out,and a regression equation is obtained which can predict the difficulty after the e vent by using the comprehensive difficulty in advance:Ex post difficulty =(10)-094.0267.0 Arithmetic level(10)0.106 Reasoning level(10)0.091 Knowledge level...
