A Statistical Analysis And Teaching Research Of Higher Education Examination Papers

Since we entered into the era of big data,we have found that probability and statistics have a wide range of applications in real life.It has penetrated into all aspects of life and production and has become a part of the knowledge quality that citizens need to improve.Probability and Statistics is an important knowledge points of high schools teaching and college entrance examination.Since the curriculum reform,Probability and Statistics has undergone major changes in the curriculum provision,the degree of difficulty and general direction of questions in the college entrance examination,etc.,which have aroused great attention of educators.Compared with the United Kingdom and the United States,the study in this area in China started relatively late.Therefore,it is of significance to sort out the examination questions related to probability and statistics and explore related teaching strategies.Through the literature review,statistical method and comparison,this paper made a statistics and analysis of the questions related to probability and statistics in the 2011-2020 National College Entrance Examination Mathematics Exam ?(Science-oriented)from the proposition background,mathematical thinking methods,core literacy perspectives.Further,the laws,characteristics and sources of questions related to probability and statistics in National College Entrance Examination Mathematics Exam ?(Science-oriented)in the past10 years were studied,hoping to provide a reference for the teaching of Probability and Statistics.This paper is divided into four parts,and the main content of each part is as follows:The introduction part describes the background,objective and significance of the research,and other related content,and summarizes the current research status at home and abroad.The second part summarizes and analyzes the distribution law and source of questions related to the probability and statistics in college entrance examination in the past ten years,aiming to explore the propositional pattern of college entrance examination through data analysis,and provide teaching suggestions for front-line teaching.The third part provides constructive suggestions for students' learning and teachers' teaching based on the characteristics of the exam questions.The fourth part carries out a teaching design with geometric probabilities in probability statistics as examples.
