Research On Teaching Design Of Mathematical Calculation In Primary School Based On Basic Mathematics Activity Experience

With the continuous progress of the new round of basic education curriculum reform,the requirements of mathematics curriculum standard for students are not only the former"double base",but also changed into "four bases",namely basic knowledge,basic skills,basic ideas and basic activity experience,which makes clear the important position of mathematics activity experience in mathematics teaching.Mathematics activity experience,as a subjective and individual knowledge in the process of learning mathematics,can be obtained through a series of activities such as conjecture,operation,verification,etc.,which can provide the corresponding learning reference and guidance for mathematics learners to learn mathematics more efficiently.The classroom is the main position of mathematics education.Because "the basic activity experience is the experience gained by students who have experienced the activity process in person or indirectly",relying on the calculation teaching content of "calculation law" in the classroom,students are guided to participate in mathematics activities in an all-round way,gain basic activity experience in the activities,stimulate students' interest in learning,and urge them to be active and rich under the guidance of teachers Learn individually and creatively.By using the methods of literature,case study and text analysis,this paper defines the basic activity experience of primary school mathematics,puts forward the characteristics of the basic activity experience of mathematics,analyzes the basic procedures of primary school mathematics teaching design,designs and expounds from three aspects:preliminary analysis,teaching design,teaching implementation and reflection,and uses the post teaching test and questionnaire survey to understand the implementation effect。It is found that the teaching design of the fourth grade students based on the basic mathematical activity experience has achieved some results,such as the enhancement of students' interest in learning,the improvement of students' participation in the classroom,the reduction of homework error rate,and the enrichment of their mathematical activity experience.At the same time,we should also improve the situation introduction,the grasp of classroom teaching time,the form of interaction between teachers and students.
