Research And Thinking On The Probability And Statistical Solution Of The College Entrance Examination

With the advent of the era of big data,the application of probability statistics has gone deep into all aspects of life and has become an indispensable part of the knowledge quality of every citizen.As an important content of high school mathematics and an important test point of the college entrance examination,its curriculum,teaching and inspection have also received more and more attention from teachers and students and educational researchers.However,compared with other countries,the teaching and research of probability statistics in China started late.Therefore,it is of great significance to strengthen the investigation and research of high school mathematics probability statistics and explore scientific and efficient teaching strategies.In an in-depth study of the study of ordinary high school mathematics curriculum standards,college entrance examination outline,high school probability and statistics courses,the national test probability and statistical answer questions of the college entrance examination for the past ten years,and related research documents,he visited the municipal and county levels of Hebei Province.Demonstrative high school,Conduct in-depth exchanges and interviews with dozens of frontline teachers,and conduct tests and various forms of interviews among students.A large number of data and materials have been collected,providing sufficient practical basis for relevant studies.On this basis,the last ten years of the college entrance examination National Science test probabilities and statistical solutions to the investigation of the situation.In the form of the test questions,the situation is novel,close to life,and the charts are diverse,rich in form,and long and difficult to understand;On the key ideas,we pay attention to the examination of sampling thoughts,statistical inference thoughts,and random thoughts;In the relevant mathematics ability,the emphasis is on the examination of mathematics reading ability,reading graph ability,data processing ability,mathematical modeling ability,computing ability,and text language expression ability;In terms of knowledge content,it has strengthened the examination of basic concepts and skills methods,important probability and statistical models,etc..At the same time,it reflects the integration of probability and statistics and the fusion of probability statistics and other knowledge.Combining the characteristics of combed out,the paper designed a targeted test questionnaire to detect the learning status of high school students’ probabilities and statistics,and analyzed the main problems in knowledge understanding,learning methods,and teaching settings.Based on the interviews with teachers and students on the first line,this paper analyzes the underlying reasons from the aspects of students,teachers and teaching patterns.According to the results of the research,combining with my teaching practice,I put forward the guiding teaching strategy from many angles: updating the teaching concept and improving the quality of teachers;Compaction the basic concept and master the basic model;Summarize skills and methods,improve literacy ability;Infiltration of core ideas,attention to knowledge integration;Strengthen practical application and cultivate innovation consciousness;Integrating information technology and infiltrating mathematics culture;Transform teaching mode,construct knowledge system,etc..A demonstration teaching design was set up,and a period of teaching experiments was conducted in a senior high school class for a period of time.Students’ performance was significantly higher than that of the control class from the aspects of daily performance and post-test.Therefore,it proves that the teaching strategy has a certain timeliness.
