Teaching Research Based On The Core Competence Of High School Students’ Mathematical Opertions

With the development of the times,the influence of mathematics is growing.Under the curriculum reform,the implementation of the core literacy of mathematics in teaching is indispensable,and the literacy of mathematical operations,as one of them,also plays an important role.Through the analysis of the research results of the core literacy of mathematical operations,the dimensions of the effective implementation of the core literacy of mathematical operations are determined,and the investigation and research are carried out from multiple angles and levels,and the strategies and ways to effectively improve the core literacy of mathematical operations are proposed from the two aspects of teaching and learning.In the process of educational practice,the author has learned that students’ mathematics ability is generally low through the demonstration of the calculation process on the blackboard by the students in the classroom,the results of the mathematics calculations of the students in the correction of homework,and the teachers’ infiltration of mathematics literacy during the course of listening to the class.It has not really been implemented.Therefore,in order to be able to understand the reasons in depth,empirical research was carried out.First of all,by consulting a large number of documents,we understand the definition of the core literacy of mathematics,the research of mathematical operation literacy,and the research of mathematical operation ability at home and abroad,and analyze the literature on the investigation and research of mathematical operation under the curriculum reform.On this basis,combined with the actual situation of the students in their internship school,the evaluation standards for the core literacy of mathematics have been formulated,mainly starting from the content(sets,functions)of high school students’ learning,and four-dimensional analysis: operation object,operation Rules,calculation ideas,calculation results,and horizontal division of the four dimensions.The test papers and questionnaire surveys were carried out according to the evaluation standards.109 students were tested and the results were analyzed;teacher interviews were also conducted.In response to the analysis of the results,the teaching strategies to implement mathematics literacy are proposed from the teacher level:(1)Under the curriculum reform,change concepts and be familiar with the new textbooks;(2)the new curriculum requires teachers’ professional quality;(3)improve students Mathematical operations interest:(1)The transformation from the instructor to the facilitator,(2)Establishing a good teacher-student relationship;(4)The application of mathematical operations literacy,mainly from the mastery of concepts,the understanding of arithmetic,and algorithms to mathematical thinking and methods Infiltration,so as to simplify mathematical operations with multiple solutions to one problem.From the student level,it is proposed to cultivate the learning of mathematical operation literacy:(1)Correct learning attitude and develop good operating habits;(2)Strengthen the learning of basic knowledge.Only when the basic knowledge is solid can the students’ mathematical operation ability improve;(3)Master the internal connections of knowledge and repeatedly train(4)Memorize and use formulas and conclusions proficiently to facilitate mathematical operations;(5)Strengthen calculations,so as to save time and increase speed in the process of mathematical operations.
