Comparative Study On The Contents Of "Statistics And Probability" In Primary Mathematics Textbooks

With the continuous development of information technology,people's daily life and all kinds of data more closely,probability and statistics knowledge as the basic theoretical tool of data processing applications in various fields have become increasingly prominent,so the education sector has increased importance of probability and statistics knowledge,and constantly improve the relevant content in the textbook module.The students first contact with the content of "statistics and probability" is in the primary school stage,at this stage of education,as the carrier of knowledge of the textbook,a guiding role in the development of education,directly related to the quality of education.With the implementation of the new curriculum reform,there have been many versions of primary school textbooks in our country.Due to the different writing ideas,there are some differences and relations between them.In this paper,Beishi and Sujiao version of the one to the sixth grade of primary school mathematics textbooks as the research object,from the teaching objectives,contents,spiral arrangement,material selection,presentation of five aspects in the two edition of the textbook of "statistics and probability" sections of the similarities and differences found:(1)In the teaching goal,Beishi textbook focuses on cultivating the students' understanding of knowledge and statistical concepts and random thoughts;Jiangsu bias in the application of knowledge.(2)In the content scope,Beishi textbook arrangement is relatively uniform,but in the third grade 2 content arrangement is too simple;Jiangsu teaching knowledge points less,compared to textbooks lack of fair play,too late to learn knowledge selection and application of fan charts and various statistical graphs.(3)In the arrangement,the two edition of the textbook the Jiangsu edition textbook more in the number of statistics section spiral,spiral time is more uniform;Beijing normal university edition textbook in the probability of spiral number.(4)In the source material,the two edition of the textbook material in the tendency of city was higher than rural tendency in urban and rural areas is not balance;Jiangsu should improve the natural environment of source material proportion,also should increase the proportion of family life source version.(5)In the presentation,use of textbooks textbook charts,language of characters is more concentrated,Jiangsu more dispersed;textbooks more emphasis on using the statistical table shows,Jiangsu on statistical chart presentation.Based on the findings,this study gives the following suggestions and opinions:(1)the textbook should strengthen the cultivation of students' thinking,cultivate students' statistical ideas and random thoughts.(2)in the breadth of content,the Soviet version should increase the probability of the contents of the content,the early learning sector statistics and the selection of various types of statistical map of the contents of the chapter,the average number of courses increased.(3)Sujiao should increase the number of spiral part of textbooks should be part of the increase in the number of spiral statistics.(4)Sujiao should improve the natural environment of source material proportion,also should increase the proportion of family life source version.(5)Sujiao should reduce the presentation of the use of charts and tables both in the lower grades,textbooks should be uniform and set up the statistics presentation.
