Study On Types And Teaching Strategies Of "Problem Solving" Examples In Mathematics Textbooks For Primary School Publishers

With the development of the times,the previous problem-solving models for "problem-solving" problems cannot meet the development needs of today’s students.Problem-solving,as the product of the era of core math literacy,has the trend of keeping pace with the times.Its educational significance lies in the comprehensive study of problem-solving,which is conducive to promoting teachers’ teaching,improving teachers’ ability to study textbooks and students’ learning,and realizing students’ innovative consciousness and personalized development.How to correctly grasp the concept of "problem solving" as well as apply it to the integration and improvement of students’ problem solving ability,it has become a difficult problem that front-line mathematics teachers have been tackling,but also an important link in the re-understanding of core literacy.Based on the literature research,it is concluded that most scholars focus on the research of "problem solving" in a certain grade,the comparative study of "problem solving" in China and abroad,and the comparative study of different textbooks.This research mainly studies and analyses 81 "problem solving" examples in the 1-6 grade mathematics textbook,divides the examples into different types,and makes a detailed study of different types according to students’ learning conditions,classroom observation and curriculum standard analysis,and puts forward the teaching strategies and teaching cases of each type of examples.This study first uses the general objective of the curriculum standard to analyze the elements of "problem solving" examples,which provides a solid theoretical basis for the following teaching focus,teaching strategies and teaching cases;secondly,classifies the examples through textbooks and makes a detailed study of their nature and characteristics;thirdly,through the analysis of curriculum standards for grades1-6,the analysis of students’ learning conditions for Grades 1-6 and teachers.Teaching analysis,specific analysis of various types of examples,for the follow-up teaching strategies and teaching cases to provide practical basis;the final conclusion of this study is that: "problem-solving" examples are mainly divided into picture type,text type,combination type and practical type,with the "problem-solving" case element analysis as the main line to propose different types of teaching strategies and teaching cases.
