Research On Primary School Mathematics Teaching Improvement From The Perspective Of Uncertainty

Uncertainty,as an important attribute of education,is often weakened and ignored when it encounters strong mathematical certainty,which eventually leads to the narrowing of mathematics courses and teaching.Based on this,the primary school mathematics teaching is reflected from the perspective of uncertainty,trying to arouse the due attention to uncertainty,rebuilding the harmony and balance of certainty and uncertainty in the mathematics curriculum and teaching,and deepening the primary school mathematics curriculum and teaching change.The main content of this study consists of the following parts:First,explain the rationality of uncertainty in mathematics teaching in elementary schools.To clarify the uncertainty through the overview of the source and use of primary school mathematics,the order of individual growth and the abundance of life,the rules of uncertainty and the charm of uncertainty in mathematics teaching in primary school,combined with the pursuit of "education" in mathematics education It is an indispensable component of elementary school mathematics teaching.Secondly,it analyzes the representation and value of uncertainty in elementary mathematics teaching.From the two perspectives of individual development and teaching process,it discusses the connotation of the uncertainty of mathematics teaching in elementary schools,and clarifies the three aspects of its uncompetitiveness,subjectivity,and disorder.And further discuss the value of uncertainty,which is conducive to teachers' re-recognition of mathematics teaching,the deepening of the mathematics teaching process in elementary schools,and the "re-creation" of mathematics learning in elementary school students.Based on the representation and value,the four aspects of mathematics teaching in primary schools(teacher concept,teaching content,teaching process,evaluation feedback)are specifically analyzed.Thirdly,from the perspective of uncertainty,it analyzes the "determined" mathematics teaching in primary schools and its causes.It was found that the "determined" elementary mathematics teaching would be embodied in the conservative orientation of teachers' ideas,the inheritance and dominance of the teaching content,the procedural tendency of the teaching process,and the reliance on evaluation feedback standards.Relying on uncertainty,try to find out the crux of the "determined"elementary school mathematics teaching,that is,the confrontation of certainty and uncertainty caused by binary thinking,and the uncertainty caused by utilitarian pursuit is ignored.The specific crux of matching with the problem is the generalization of the certainty consciousness of primary school mathematics teachers,the challenges of teaching and learning caused by the characteristics of uncertainty,the contempt of primary school mathematics teaching for subjectivity,and the dominance of absolute authority of primary school mathematics evaluation.Finally,the improvement of elementary mathematics teaching based on uncertainty.Four major aspects of primary school mathematics teachers' practice of "teaching" and "education",dialectically presenting certainty in primary school mathematics content,vividly highlighting the attributes of life in primary school mathematics,and multi-level care and development of primary school mathematics evaluation have been improved.Explore the value of uncertainty in elementary school mathematics teaching,with a view to bridging the narrowing of mathematics caused by "determination",better dialectically implement the direction and pursuit of cultivating mathematics literacy in elementary school mathematics teaching,and restore the rich and generative Mathematics teaching ecology.
