Research On The Application Of Mathematical Experiment In Junior High School Statistics And Probability Teaching

Under the traditional policy of "test scores",mathematics as an effective m eans for cultivating students' thinking ability is only reflected in the students' problem-solving ability,or mathematics test results is good,but in the new cur riculum reform advocates,under the advocacy of mathermatics classroom teachin g should pay attention to stimulate students' interest in learning,pay attention to the practice of students,so that students can have enough time and space expe rience observation,experiment and mathematical process.The mathematical experi ment is a kind of inquiry learning based on students' active participation,is also a kind of efficient teaching mode,is particularly important for the developme nt of students' practical and innovative consciousness.Statistics and probability are one of the important contents of mathematics learning in junior high school,and they are widely used in real life.In the tea ching of probability and statistics,it is necessary for students to know the rela tionship between frequency and probability,to realize the relationship between t he sample and the whole,to realize the possibility of random events,to experi ence the process of data collection and sorting.The use of mathematical experi mental teaching,students can experience the whole process of data statistics,e xperience the randomness of the event,it can be seen that the mathematical ex periment in the teaching of probability and statistics is very important.Howeve r,in the classroom of probability and statistics on the reality,many teachers d o not want to spend time doing mathematical experiment,one reason is that th e delay time,can not complete the task of teaching,on the other hand,is una ble to do for the mathematics experiment teaching.Combined with the above s ituation,this dissertation puts forward the corresponding teaching strategies and design the corresponding teaching cases.On the basis of the daily practice in the junior high school mathematics t eaching experience,is divided into 5 chapters,the first chapter expounds the re search background and the problems;the second chapter through the literaturereview,the application status of mathematical experiment introduced the existin g in the teaching of probability statistics;the third chapter through access to re levant information,and read to the junior middle school this type of teaching,mathematical experiment in the teaching of probability statistics and the imple ment of mathematics experimental teaching necessity and feasibility;the fourth chapter is the main content of this study,one is to explain the theoretical basi s of this study,on the other hand,describes the mathematics experiment applic ation strategy in the teaching of probability statistics,mainly involves the desig n and application of three dimensions and related case learning environment,te achers' teaching and students' learning;the fifth chapter summarizes the study a nd reflection.Through the research,it is found that,in the teaching of probability and statistics,the main types of mathematical experiments are the use of computer simulation experiments and the use of teaching aids and other physical experim ents.The application of mathematical experiment in teaching probability and st atistics is necessary,can make statistical concepts become intuitive,can exercis e the students' application consciousness and the ability of the operation;the a pplication of modern information technology in mathematics teaching,the refor m of teaching methods and students' learning of teachers,making the applicatio n of mathematics experiment in the teaching of probability statistics is feasible.The implementation of the mathematics experiment should pay attention to the following strategies:(1)mathematical experiment the reasonable use of compu ter display;(2)pay attention to the penetration of mathematical thinking,inclu ding statistics,probability and statistics of random thoughts,the thought of mat hematics model;(3)pay attention to mathematics experimental interest,which mainly includes two parts.One is the material of mathematics experiment to b e interesting,two is the experiment tool of mathematics experiment to be inter esting;(4)pay attention to the cultivation of students' practical operation abilit y and application consciousness;(5)pay attention to the creation of good expe rimental environment.
