Investigation And Research On The Numeracy Ability Of Third-grade Students

Operation ability is one of the three basic abilities of mathematics,and also one of the ten core concepts proposed in the curriculum standard,which accounts for a large proportion in mathematics learning and application.Primary school is an important period to cultivate students' operation ability.In order to understand the current situation of the third grade students' arithmetic ability of addition and subtraction within ten thousand,according to the requirements of the curriculum standard,and according to the mathematical subject ability model of Professor Lin Chongde and the theory of thinking,a test paper was compiled,with 280 students in a primary school in Xinzhou City,Shanxi Province as the survey object.The collected data were analyzed,and the following results were obtained through SPSS 23.0 data statistics and qualitative analysis:1.Overall performance of operation ability: the overall level of operation ability of grade three students in addition and subtraction within ten thousand(2)is not high,there is no significant difference between boys and girls,but girls' performance is better than boys'.2.The specific performance of operation ability: in addition vertical calculation,the students in the three groups of high,middle and low are not affected by the increase of carry times;in subtraction vertical calculation,the influence of the increase of abdication times is less,and will be affected by the 0 number of the subtracted.3.The expression of thinking quality in operation: in the expression of students' thinking quality in operation,the profundity is the best,and the creativity is the worst;There is no significant difference between boys and girls in their thinking quality.Girls' thinking quality is better than boys' overall performance;Each thinking quality is related to each other,and has a very significant correlation with the overall performance of thinking quality.4.There are subjective and objective factors that affect the development of students' mathematical operation ability.The subjective factors include the errors and omissions of students' short-term mental memory,the negative influence of thinking set and the lack of good thinking quality,as well as the influence of non intelligence interest and habit of operation.Objective factors include the influence of teachers' teaching methods,teaching ideas and the arrangement of teaching materials.Based on the above conclusion,the following suggestions are put forward toimprove the students' operation ability of addition and subtraction within ten thousand(2): pay attention to calculation teaching,improve students' logical ability,cultivate students' thinking profundity;analyze and utilize students' mistakes,cultivate students' thinking criticality;diversify calculation methods,cultivate students' thinking flexibility;encourage creativity,cultivate students' thinking creativity ?...
