Investigation On The Present Situation Of Mathematics Expansion Practice Teaching In Primary Schools Implementation Strategy Study

"Compulsory Education Mathematics Curriculum Standards(2011 Edition)" points out that mathematics teaching should be oriented to all students and meet the needs of students at different levels.But the actual implementation is difficult to put in place,especially under the large class teaching,to meet the development needs of middle and upper level students can not be reflected.In addition,changes in the overall environment cause the lack of internal learning motivation of primary school students,students have no interest in learning,no goals and other problems are common.By combing relevant literature at home and abroad,this study defines the two concepts of "extended curriculum" and "extended practice of primary school mathematics",and clarifies the research status of extended practice of primary school mathematics.Combined with relevant theories and research basis,this study is carried out from two aspects: the current situation of extended practice of primary school mathematics and the exploration of teaching strategies.Through investigation,interview and analysis,it is found that there are the following problems in the implementation process of mathematics expansion practice teaching in primary schools: teachers lack of awareness of teaching objectives,selective teaching and coping teaching behaviors;The content source of extension exercise is single,which is in the present situation of emergence only teaching,and the resources are lack of systematization.It is difficult to implement the hierarchical teaching of extended practice;There is a contradiction between the high expectation of students and the low attention of teachers.The teachers ignore the instrumental function of the extension exercise and do not play a role.The evaluation method of teaching implementation process is simple and the feedback effect is low.In the research process,empirical research method was adopted to try to put forward corresponding strategies for the problems existing in the teaching implementation.The teaching was carried out with the help of front-line teaching advantages.Through the analysis of the implementation process and results,the strategies were adjusted and modified to determine feasible teaching strategies: teachers should establish a teaching concept of "meeting the needs of different students";Relying on the mathematics teaching objective,it is clear that the teaching objective of extended practice;Expand the resources of extension exercise and form the systematic content of extension exercise;With the help of information technology platform,to achieve hierarchical exercises;Give students positive expectations,and promote the unity of needs and actions;Increase the successful experience of students and make good use of the tool function of the expansion exercise;Optimize the evaluation mechanism of extension exercises,and provide feedback to help students learn.
