From Abstract Mathematics To Concrete Experience ——A Study On The Strategies Of The Life-based Mathematics Teaching Content In Primary Schools

Paying attention to students' existing experience is not only the internal requirement of primary school mathematics curriculum reform,but also the practical need of optimizing teaching practice.The life-oriented transformation of teaching content,that is,the transformation of abstract mathematical knowledge into children's specific practical experience,is the basis and premise of life-oriented teaching of mathematics in primary school.It is not only conducive to the scientific construction of primary school students' mathematical cognitive structure,but also conducive to the improvement of primary school students' mathematical core literacy.Through the method of literature research,this study makes a detailed study on the theory and practice of living teaching content at home and abroad,and combs the current situation from four aspects: the connotation of living mathematics,the significance of living teaching content,the current situation of living teaching content and the strategy of living teaching content.It is found that there are many researches on the theme of life-oriented teaching,and the special research on the life-oriented teaching content is relatively insufficient,that is,there is a lack of systematic research on how to return mathematical conclusions to children's specific experience.Based on Dewey's children's experience curriculum theory,Tao Xingzhi's life education theory and friedenthal's mathematical reality theory,this study uses the methods of questionnaire and interview to understand that although some front-line teachers have made a lot of exploration on life-based teaching,generally speaking,most of these experiences are fragmented and superficial,which have not risen to the height of theory and need to be further sorted out and summarized.The specific performance is that the implementation of life-oriented teaching content in teaching practice is scattered and random on the whole,and the consciousness and systematicness of teachers' implementation are not strong.According to the above problems,this study explores the implementation ways of the life presentation of mathematics teaching content in primary school.According to different sources of experience,it can be divided into the following three categories,The first type is based on children's daily life experience,which returns to the real object in life,the daily life situation,the common graphics and pictures and the children's life language respectively;The second is based on children's practical experience,which is materialized into children's hands-on operation activities,children's physical and mental coordination activities and children's game activities;The third category is to design small mathematical experiments and special inquiry activities based on children's special inquiry experience.On this basis,it further discusses the basic principles of the life-oriented teaching content,that is,to establish the concept of extensive application of mathematics,be good at accumulating life materials,accurately grasp the realistic performance of mathematics and expand students' access to practical experience.Based on the above principles and approaches,this paper explores the strategies of life-oriented mathematics teaching content in primary school,mainly including tracing the source based on life situation,excavating mathematical historical materials and seeking roots,restoring with the help of mathematical thought and method,transforming with textbook materials and childishness according to students' thinking level.According to these strategies and combined with the content of primary school mathematics curriculum,this paper designs typical cases in order to provide practical strategic reference for the life of primary school mathematics teachers' teaching content.
