Research On Teaching Improvement Of “Measurement Of Figures” From The Perspective Of Primary School Mathematics Core Competence

Our country is at the intersection of two centuries of history,and the development of society has put forward new requirements for the quality of talent training.With the continuous deepening of basic education reform,the focus has gradually focused on the cultivation of the core literacy of students,especially the core literacy of the subject.From the perspective of the core literacy of mathematics,the research on the teaching strategy of“graphic measurement” plays an irreplaceable role in the development of pupils' thinking and the improvement of pupils' mathematics literacy.This research takes two teachers Z and S as examples,using classroom observation method to go deep into the front line of teaching and obtain first-hand materials by recording classroom teaching procedure,in order to explore the implementation of the cultivation of students' core literacy in mathematics through the observation and analysis of these two teachers' lessons.The current study has shown that the cultivation of students' core literacy in mathematics is involved in both two teachers' classes.It is comprehensive to some extent,but there also exists some problems.To begin with,the training of geometric intuitive literacy in students' hands-on training is not in place.Since then,students' overall spatial imagination ability is relatively weak.Furthermore,the number of exercises in the cultivation of students' mathematical operation literacy is not enough.Last but not least,the cultivation of mathematical abstract literacy lacks systematic generalization of knowledge and the design of teaching situations is unreasonable.Meanwhile,In the process of cultivating students' logical reasoning literacy,the study found that they lack conjecture in logical reasoning and their logical reasoning ideas are not clear enough.In the process of cultivating mathematical cultural literacy,students' mathematical language expression lacks of enough accurency and teachers neglect to teach students the history of mathematics;the mathematical language is inaccurate and the cultivation of mathematical teaching history is ignored.Last but not least,the information extraction is inaccurate when the teachers train students to form data analysis literacy.Based on the above analysis,this research puts forward the following suggestions for improvement: In terms of cultivating students' geometric intuitive literacy,attention should be paid to students' hands-on operation ability.At the same time,teachers should strengthen the training of students' spatial imagination ability.In terms of cultivating students' mathematical operation literacy,teachers should provide more consolidation exercises for students.In terms of cultivating students' mathematical abstract literacy,teachers should pay attention to students' cognitive foundation and the creation of teaching situations.Make reasonable conjecture and clarify logical thinking in the cultivation of students' logical reasoning literacy.Improve the accuracy of mathematical language when teachers cultivate students' mathematical cultural literacy,and they should help students understand the generation and development of mathematics.Finally,extract effective data in data analysis and should not ignor the cultivation of data analysis literacy as well.
