A Comparative Study Of Probability In New And Old High School Mathematics Textbooks

In 2003,the Ministry of Education issued the general high school mathematics curriculum standard(Experiment),which provides guidance for the practice of high school mathematics curriculum reform in the past ten years.With the development of the new era,the Ministry of education restarted the revision of high school curriculum standard,and promulgated the general high school mathematics curriculum standard(2017 Edition)in 2018.The revision of the new curriculum standard puts forward some suggestions for the compilation of teaching materials The content of probability is different from the traditional mathematics teaching.The research object of probability is random phenomenon,which provides an important thinking mode and problemsolving method for people to understand the objective world from the perspective of uncertainty.The content of probability occupies an important position in the high school curriculum.Therefore,this paper compares the probability content of the new and old high school textbooks to promote teachers' understanding and grasp of the probability content of the new textbooks,so as to better guide teaching.This paper selects "ordinary high school textbook � Mathematics(people's education A Edition)" and "ordinary high school experimental textbook � Mathematics(people's education A Edition)" as the research object,adopts literature research method,comparative research method,content analysis method and other research methods,from the curriculum standard,textbook structure,knowledge system(including knowledge structure and specific knowledge points,content breadth and depth),auxiliary knowledge construction This paper compares the probability content of the two editions from six aspects,including mathematical exploration,information technology,mathematical examples,exercises and difficulty of teaching materials,and draws the following conclusions:(1)the new textbook inherits and gives full play to the chapter structure characteristics of the old textbook,and enhances the learning guidance;(2)the new textbook follows the concept of "highlighting the main line and selecting the content" of the curriculum standard to analyze the probability content The curriculum content has been adjusted to improve the probability knowledge system;(3)the new textbook focuses on the construction process of probability knowledge,enriching the mathematical activity resources of probability part;(4)the new textbook focuses on the ways to solve probability problems,providing more method guidance;(5)the new textbook updates the selection of background materials and teaching tools of probability content,reflecting the changes of the times;(6)The new textbook enlarges the breadth,depth and comprehensive difficulty of the probability part.Based on the comparative content and the above research conclusions,this paper puts forward the relevant teaching suggestions of probability content:(1)grasp the key and difficult points of probability according to the requirements of curriculum standard;(2)grasp the probability knowledge as a whole to help students establish the probability knowledge system;(3)pay attention to the penetration of mathematical thinking methods in probability teaching to promote the development of students' literacy;(4)advocate the experience inquiry type of probability learning In order to promote students' understanding of probability content,we should strengthen the connection between probability and reality,enrich the creation of probability situation,and pay attention to the deep integration of information technology and probability content,so as to improve the effectiveness of probability teaching.
