Research On The Teaching Design Of The "Comprehensive And Practical" Activities Of Primary School Mathematics From The Perspective Of "Three Connections"

For the first time,the "Compulsory Education Mathematics Curriculum Standards"clearly emphasizes that "integration and practice" activities are an inseparable part of primary school mathematics teaching.This is also a reform and breakthrough of the traditional mathematics teaching model.The "integration and practice" of mathematics is the touchstone for primary school students to master mathematics knowledge,and also the result of students' test learning.The teaching of "comprehensive and practical" activities is the standard for testing students' application of theoretical knowledge to practice.Teachers consistently act as guides and encourages in the process of integration and practice,constantly guiding students to discover mathematical problems,analyze mathematical problems,find ways and ways to solve problems,and give students timely encouragement and establish correctness.Learning concept.Guide students to learn to communicate,communicate and cooperate with their peers.In order to achieve this goal,teachers should spare no effort to emphasize the important role of "three links in teaching in the process of mathematics teaching.The so-called "three links"are the connections between the internal knowledge of exponential;the connection between mathematics and life;the connection between mathematics and other disciplines.It is an important research direction to improve the teaching of "comprehensive and practical"activities in primary school mathematics from the perspective of "three links".Through a self-developed "three links" perspective,"The Current Situation of Mathematical Integration and Practice Teaching in Primary Schools",a questionnaire survey was conducted randomly among mathematics teachers in many primary schools in Chongqing,supplemented by classroom observation and Teachers conduct interviews and use real classroom cases to conduct in-depth research on the teaching of "comprehensive and practical" activities in primary mathematics,focusing on the frequency of teaching,the basis for making goals,and the achievement of goals,the source of the theme,the theme determiner,and the topical focus.The teaching methods and teaching focus have been investigated and analyzed in detail.It is finally found that in the actual teaching process of primary school mathematics,the teacher's concept of using "three links" in real life is very weak,which leads to There are various problems in the design of mathematical activities,which makes the application of "three links" in the process of mathematics teaching not obvious.On this basis,the author obtained the teaching design principles and strategies of "comprehensive and practical" activities of primary school mathematics from the perspective of "three links",and selected two typical "comprehensive and practical" activities of "experience kilometer" and "intelligent surveyor" for teaching design.Through research,this paper concludes that in the teaching design of mathematics "comprehensive and practical" activities,there are mainly the following problems: the teaching goal is not rigorous enough,the teacher ignores the importance of activity theme design,the teaching process attaches more importance to the result than the process,and the subject status of students in comprehensive practical activities is not obvious.In view of the above problems,the author,after deeply studying the relationship between "three links" and primary school mathematics,drew three principles and three strategies for the teaching design of "comprehensive and practical" activities.Based on the above conclusions,the author conducted a reflection on the design and research of teaching cases.
