The First Semester Is Based On The Research On Teaching Strategies Of Solving Problems "speaking Mathematics"

"Talking Math" is the unity of the means and goals of mathematics learning,and the ability to solve mathematical problems is an important symbol of students' mathematical literacy.In practical teaching,students' ability to solve mathematical problems and expression are facing difficulties.The mathematics curriculum standard for compulsory education emphasizes that students can understand and master basic mathematical knowledge and skills,mathematical ideas and methods,and obtain basic mathematical activity experience through mathematical expression.In the first learning section,"Talking Math" is mainly a visual mathematical language,which is an oral expression based on operations and situations with specific mathematical problems.Students' ability to solve problems and the ability to "Talking Math" affect each other.The lack of students' ability to solve problems will lead to unclear mathematical expression,which will expose the confusion of students' ideas to solve problems.Based on the problem-solving teaching of mathematics in the first learning stage,this paper takes the "Talking Math" activity as the teaching starting point,and explores relevant teaching strategies to improve students' mathematical expression ability and problem-solving ability.The first chapter is the introduction,which mainly discusses the research background,significance,content,methods and research ideas.Firstly,this paper uses the literature research method to understand the existing research results and shortcomings of "Talking Math" and mathematical problem-solving at home and abroad.Based on the curriculum standards of compulsory education and the teaching materials of people's Education Edition,this paper analyzes the problem-solving teaching examples in the first learning stage,and determines the teaching content to be studied in this subject.Then,through the methods of questionnaire and interview,this paper understands the speech and "problem-solving" situation in mathematics classroom from the two dimensions of students and teachers,and the guidance and demonstration role of teachers in "Talking Math",obtains some suggestions for carrying out "Talking Math" activities from the teacher interview,and carries out a post-test on students' "Talking Math" after practicing the strategy of "Talking Math",It is observed that students "Talking Math" is somewhat better.Using the method of empirical research,this paper presents the process and characteristics of students' "Talking Math" through the "problem-solving" classroom in the first learning paragraph 6,compares the students' expression ability and problem-solving ability before and after teaching practice,and tracks the practical effect.Finally,based on the characteristics of students' "Talking Math",this paper puts forward effective strategies.This paper summarizes the characteristics of "Talking Math" of students in the first learning period in teaching practice:(1)there are certain teaching procedures.(2)The presentation content is based on the problem situation.(3)Diversity of subject level.(4)The essential feature is interactive communication.(5)The integrity and organization of the expression are insufficient,but they are strengthened step by step.Based on the above characteristics,this paper puts forward corresponding strategies on how to operate the procedure of "Talking Math",use the problem situation,guide students at different levels to "Talking Math",improve students' "listening" and "speaking",promote classroom communication and interaction,and guide the integrity and organization of "Talking Math".
