The Teaching Research Of Probability And Statistics Based On The Reform Of New College Entrance Examination

The probability and statistics part is one of the important examination points of the college entrance examination,which has caused teachers and students' more attention in high school.Due to probability and statistics in the high school involved more knowledge points,a wide range of examination content,and the new curriculum standard on the probability and statistics module changes greatly,the college entrance examination site is also changed,which brings some trouble to the actual teaching.The teaching of probability and statistics is not only the mastery of knowledge,but also the comprehension of thinking methods and the application of practical problems.Therefore,it is of great significance to strengthen the investigation and research on probability and statistics in high schools and to explore better teaching strategies.Firstly,this thesis summarizes the research contents of domestic and foreign probabilistic and statistical literature,compares and analyzes the probabilistic and statistical contents of the old and new curriculum standards,and summarizes the probabilistic and statistical part of the national college entrance examination paper in recent years.Secondly,a large number of data were collected from senior high school students through the test investigation.The probabilistic and statistical part of the national college entrance examination paper in recent years was sorted out and studied.Summarize the characteristics of the answer to fill in the blanks and answer: the choice of the answer to fill in the blanks is broad,the focus is on the basic knowledge and basic skills.There are abundant charts involved in the solution,and there is not only the integration of probability and statistics,but also the integration of knowledge with other modules.Both the answer question and the fill-in question have various forms of examination,the questions are close to life,the focus is on the probabilistic statistical model and the practical application.Thirdly,in order to understand the students' grasp of probability and statistics,test paper was designed to detect the learning status of probability and statistics of high school students.Through the test results,the main reasons for the students' mistakes in solving the problem and the problems in doing the problem are analyzed.In this thesis,we also makes a comparative analysis of the content framework,knowledge arrangement and modification of the old and new curriculum standards,and finds that compared with the old curriculum standards,the new curriculum standards arrange knowledge points step by step,which is more in line with the law of students' cognitive development,the addition and deletion of content are reasonable,and the requirements of the new curriculum standards are more specific.Finally,based on the above three parts of the research results,we put forward the following five teaching suggestions: attaching importance to the teaching of ideological methods;focusing on comprehensive exercises;strengthening the integration of information technology and probability and statistics;developing students' core qualities in the course.At the same time,combining with the new teaching material,a teaching design is set up,and the teaching implementation is carried out in a class of senior two,and the good effect and evaluation are achieved.
