Research On The Problems And Countermeasures Of Teaching Of Operation Laws In Elementary Schools

Operation Laws are important content of elementary school mathematics knowledge,which have important disciplinary value and unique educational significance.As far as mathematics is concerned,Operation Laws are organically related to the operations,which is the basis of the operational method and the cornerstone of algebraic calculation.In mathematics teaching,knowledge of Operation Laws are an effective carrier to permeate mathematical thoughts.The exploration of Operation Laws are conducive to accumulating students’ experience in mathematical activities,the application of Operation Laws are conducive to improving students’ thinking quality,and the study of Operation Laws are conducive to improving students’ mathematical literacy.This study mainly adopts literature research method,questionnaire survey method,interview method and test method,taking primary schools S district of Fuzhou city as an example,to explore the current situation and problems of teaching of Operation Laws in primary schools.The main problems found in this study are: biased understanding of the value of Operation Laws,simplifying the process of exploration,ignoring the analysis of computational theory,and lack of attention to the meaning of Operation Laws.On the basis of exploring the causes,this study puts forward the teaching strategies of Operation Laws based on the theory of meaning construction.First of all,with the help of life situation to promote students to understand the Operation Laws.Secondly,it puts forward some enlightening questions to explore the meaning of Operation Laws.Finally,multiple help is provided for the flexible application of Operation Laws.Teachers can design hierarchical exercises for students,organize diversified exchanges and strengthen heterogeneous comparison and other substantive help,so that students can flexibly apply Operation Laws.
