Construction And Application Of Comprehensive Difficulty Model For New College Entrance Examination Mathematics Questions

In 2014,China launched a new round of college entrance examination reform,the new college entrance examination goal from the test of the "four basics" mastery and application level to test the fundamental task of cultivating morality,the core literacy of the discipline and the implementation of key abilities,which put forward new propositional requirements for the new college entrance examination,and would undoubtedly make corresponding changes in the difficulty of the test questions and the measurement assessment.With the advancement and deepening of the new round of curriculum reform,the attention of all walks of life to the college entrance examination continues to rise,especially the difficulty of the new high school examination questions.The college entrance examination mathematics not only has the function of selecting talents,but also helps students to recognize the role of mathematics in solving problems and promoting social development.So how to evaluate the difficulty of the new college entrance examination mathematics questions is particularly important.Under the background of the new college entrance examination reform,this study constructs a comprehensive difficulty model of the new college entrance examination mathematics questions based on the “Evaluation System of China College Entrance Examination”.And uses this model to evaluate the new college entrance exam mathematics paper I and Ⅱ volume from 2020 to 2022.The specific research contents are as follows:1.Construct new college entrance examination nathematics questions.Firstly,Based on the“Evaluation System of China College Entrance Examination”,the comprehensive difficulty model of the existing literature was adjusted and optimized according to the examination characteristics of the new college entrance examination mathematics questions,so as to construct a new college entrance examination mathematics comprehensive difficulty index model with nine factors: question background,parameter content,calculation level,reasoning ability,intuitive imagination,knowledge synthesis,problem-solving thinking,cognitive level and openness.And then in view of the shortcomings of the existing model weighting method,we use the Interval value intuitionistic fuzzy best worst method to calculate the weights of the difficulty indicators and difficulty levels,so as to establish a more scientific and reasonable comprehensive difficulty coefficient model and further improve the comprehensive difficulty model.2.Application of comprehensive difficulty model of new college entrance examination mathematics questions.Firstly,we divided the new college entrance examination mathematics paper questions into three main lines of function,geometry and algebra,and statistics and probability according to the main line of content in the new course standard.Secondly,we applied the proposed comprehensive difficulty model of new college entrance examination mathematics questions to analyze difficulty characteristics of the new college entrance exam mathematics paper I and Ⅱ volume in 2020--2022 from the different levels of each difficulty index,each difficulty index and the comprehensive difficulty analysis.3.According to the overall study of the “one core,four layers and four wings” from“Evaluation System of China College Entrance Examination”,we made an overall analysis of the new college entrance exam mathematics paper I and Ⅱ volume in 2020--2022,so as to summarize the overall characteristics of the new college entrance examination mathematics paper.Then,based on the difficulty analysis of the new college entrance examination mathematics questions in 2020--2022,the difficulty characteristics of the new college entrance examination mathematics questions are summarized from each main line.4.Research feedback on the comprehensive difficulty of new college entrance examination mathematics questions.According to the previous three parts on the comprehensive difficulty model,application and difficulty characteristic analysis of new college entrance examination mathematics questions,we put forward to corresponding suggestions from the aspects of test paper ordering,teacher teaching,student learning,and prerequisite learning for the research conclusions.
