A Study On The Application Of The Thought Of Combination Of Numbers And Forms In Mathematics Teaching In Primary School

The beginning of the 2011 edition of the Mathematics Curriculum Standard for Compulsory Education points out that "mathematics is the science of studying quantitative relations and spatial forms," and the visible number and form are the main research objects of mathematics.The combination of numbers and shapes can break the situation of number and shape splitting,and connect image thinking with abstract thinking by means of "helping numbers with shapes" and "solving shapes with numbers ",realize the complementary advantages of numbers and shapes,and promote the solution of problems.However,from the current situation of investigation,there are still some problems in the combination of infiltration number and shape,and the teaching level of teacher number and shape combination needs to be improved.Therefore,this study focuses on the key theme of the combination of numbers and shapes Using questionnaire survey method and test questions to investigate the students' understanding and application ability of logarithmic form combination,combined with the analysis of teachers' interviews and classroom observation,the research ideas are put forward on the basis of the research.It is found that most teachers have a certain understanding of the idea of combining numbers and shapes,and will also apply the idea of combining numbers and shapes in teaching.However,in teaching,teachers still have the problems of incomplete understanding,disjointed knowledge and practice,uncertain timing of application and insufficient evaluation.These issues require the attention of educators.Therefore,based on the analysis of teachers' teaching cases and combined with the investigation results,this study puts forward corresponding suggestions:strengthening teachers' own study and research on mathematical ideas,reflecting on practical teaching;constructing research teams in schools to form a learning community;and infiltrating the idea of combining numbers and shapes through various activities.Because the investigation object and condition of this study are limited,there is no practical demonstration on the teaching suggestions put forward,so the popularization degree and depth of the research results need to be strengthened,which will be improved in the future research,and the practical demonstration of the proposed suggestions will be carried out.
