The Research On The Instructional Strategies Of Mathematics Operation Skills In Primary School

This study aims at summarizing the universal and effective instructional strategies on arithmetic skills of primary school.The study is helpful to implement the double-base target,helps students to accumulate math activity experience,perceive the mathematical thinking,and promote students’ core mathematics literacy.This study found that the main problems of teaching elementary arithmetic skills is no effective communication between the spontaneous method of students and general method.In this study,four general strategies are put forward.First,the macro level focus on the unity of operation content.Longitudinally,new skills assimilated by transferring the same computing skills;Transversely,Emphasizing the connection and transformation of different arithmetic skills;Second,middle level attaches the importance of algorithm and calculation witch promoting mutually,with the help of intuition on calculation to make algorithm promoted;with the help of generals of algorithm to integrating calculation,with mixing together to fuse algorithm and calculation;with help of experience of process to promote the results.Third,Micro level focus on sorting the hierarchy of arithmetic skills.the study process from the physical operation,intuitive imagination to symbolic representation is advocated.Fourth,the key is the relevance of action and mind,witch need to guide the students to achieve the following transformation:ing from the physical operation to symbolic operation gradually,simplifying from original operation to simple operation,thinking from operation to relationship.
