A Comparative Study Of The Problem Posing In Junior High School Mathematics Textbooks

With the development of information and innovation,problem-posing and problem-solving are complementary.Mathematical problems play an important role in fostering students' innovative power.At the same time,the compulsory education curriculum standard clearly states that the training of the ability to put forward problems will run through the whole nine years of compulsory education.Therefore,the compilation of problems in teaching materials has gradually become the focus that attracts attention in the field of mathematics education.This study uses literature review,content analysis and comparative research to make a static comparison among Qingdao edition,Beijing normal University edition and Su Ke edition of junior middle school mathematics teaching materials.This thesis analyzes the dimensions of the compilation and distribution of the problems in the three versions of the teaching materials,sums up the common points and differences existing in each dimension,and puts forward some corresponding suggestions according to the advantages and disadvantages of the problems,so as to perfect the compilation of the problems in the mathematics teaching materials.This thesis studies the three versions of mathematics teaching materials according to the total number of mathematical problems,the types to which the questions belong,the teaching links in which they belong,and the knowledge fields to which they belong.The examples are compared with the real situation and the seven dimensions of the sentence pattern type,and the following common points are found:(1)the number of questions raised is much lower than the number of mathematical problems in the textbook;(2)the problem setting in the textbook is the most common in the seventh grade and the least in the ninth grade.(3)the problem is written in the type,the teaching link and the knowledge field to which it belongs.The differences among the three versions of textbooks Nature:(1)Qingdao edition pays more attention to the setting of questions in teaching materials,mainly heuristic questions,(2)the textbook of Beijing normal University focuses on the compilation of open questions in exercises,and(2)the textbook of Beijing normal University focuses on the compilation of open questions in exercises.(3)Su Ke edition focuses on the activity operation of independent inquiry in the compilation of teaching materials.Based on the research on the setting of problems in junior middle school mathematics teaching materials,there are the following enlightenments.In the compilation of teaching materials,we should appropriately increase the compilation of questions and enrich the diversification of the types of questions raised.We should adjust the integrity of the teaching link in which the problem is put forward,balance the distribution of various fields of knowledge,and strengthen the realistic situation in the question-raising.The innovations of this study are as follows:(1)this thesis studies the compilation of problems in junior high school mathematics textbooks in Qingdao edition,Beijing normal University edition and Su Ke edition,and the research object is new.(2)the analytical framework proposed by constructing the problems in this paper is relatively novel.
