Study On The Characteristics Of Exercise Design And Achieving Strategies In High-quality Classroom Of Primary Mathematics

With the deepening of educational reform and the development of educational concepts,the effectiveness of classroom teaching has attracted the attention of educational researchers.As a part of primary school mathematics classroom teaching,the effective design of classroom exercises is of great significance to lighten students' schoolwork burden and improve the quality of teaching.Through literature review and analysis,it is found that there are some problems in primary school classroom exercises,such as unbalanced structure,monotonous content,closed form,high negative and inefficient.Therefore,it is hoped that through the study of the characteristics of practice design in high-quality primary school mathematics classroom,we can get the strategies to achieve effective design of primary school mathematics classroom exercises,and achieve the goal of "reducing burden and improving quality" of classroom exercises.Through literature reading,this paper explores the connotation,characteristics and value orientation of high-quality classroom and practice in elementary mathematics,and provides theoretical basis for the design strategy of classroom practice in elementary mathematics.And select high-quality classroom video as the research object,with the help of classroom interaction analysis system and Nvivo software to analyze the sample video,present the process of classroom practice in a quantitative form,analyze the visual results of some classroom practice teaching behavior in high-quality classroom,and combine with the analysis of the design of exercise content,get the design characteristics of high-quality classroom practice: first,from point to surface.” The second is to make full use of variants to construct conceptual cognition,and the third is to combine conceptual teaching with experiential teaching.Mathematics knowledge has strong systematic and scientific characteristics,and can be used as a basis for judging students' mathematics learning results through specific behavior.Therefore,based on the characteristics of the practice design of high-quality classroom in primary schools,this paper puts forward the strategy of designing the practice of primary school mathematics classroom by means of reverse design method,and the key points of the design are as follows: first,to analyze the needs of learners and ensure that the practice is suitable for students' life;second,to find out the "key problems" to promote the development of students' key mathematical abilities;and third,to ensure the typicality and appropriateness of the practice.Pay attention to the students' recent development zone.Some suggestions are put forward for the implementation process: firstly,teachers should correctly understand the mathematics classroom exercises so that each learning society feels listened to and respected;secondly,effective questioning should be carried out around the "key issues";finally,multiinteractive teacher-student relationship should be constructed to reflect students' subjectivity.Through "reverse design",students can accurately grasp the knowledge and skills they need to learn and master,but the specific implementation should also be adjusted according to the specific teaching content and students' actual situation,taking full account of teaching methods,teaching conditions and other factors,so as to achieve better classroom practice design effect.
