Research On The Training Strategy Of The Combination Of Numbers And Shapes In Senior High School Under The Subject Core Literacy

Since the new century,mathematical literacy has become the basic literacy of modern citizens.China has begun to study mathematics literacy in the year of 2000,the purpose is to let students have the basic mathematics literacy that citizens should have,in order to promote the overall development of society and individuals.According to the mathematics curriculum standards of senior high school(2017 Edition)definition and explanation of the mathematics core literacy,it requires six of which to be integrated into the actual teaching,this has brought new opportunities and challenges to the teaching research of the combination of numbers and shapes.This paper uses the methods of literature research,questionnaire,analysis,interviewing and observation to serve the study.First of all,it aims to define and study the connotation of mathematical core literacy and the combination of numbers and shapes and studies the relevant theories.Secondly,the combination of numbers and shapes is divided into three categories:shapes by numbers,numbers by shapes,numbers and shapes,and the application of the combination of numbers and shapes in the problems of set,trigonometric function,function and equation,vector,conic and so on.Again,by consulting the relevant literature,and combining with the textbooks,the combination of numbers and shapes is divided into three dimensions,the author complied the teacher interview test papers,the test papers of the combination of numbers and shapes and the questionnaire of influencing factors of the combination of numbers and shapes.The test objects of this paper are senior three students in Yanji city high school,in order to understand the situation better,the author randomly selected individual students and teachers to interview when collected the test papers.This paper analyzes the data of the test papers from three aspects:the overall development of the combination of numbers and shapes of senior three students,the situation of the students in the experimental class and the ordinary class,and the differences between the students of different genders.In addition,the author also analyzes the influencing factors of the combination of numbers and shapes of the senior three students.According to the analysis of the results of the questionnaire and combined with some summaries in the research process,this paper puts forward the training strategies of the combination of numbers and shapes based on the core literacy of mathematics:Pay attention to the teaching of the combination of numbers and shapes in the new curriculum reform to improve the mathematical abstract literacy;Study the typical examples of the combination of numbers and shapes in the textbook to pay attention to students’ foundation and basic skills;Guide the students to summarize and sum up,train the thinking of the combination of numbers and shapes,improve the logical-reasoning literacy;Through the use of information-based teaching technology,enhance the ability of drawing,improve the visual imagination literacy;Add the practical problems to situational teaching,improve the mathematical modeling literacy.In a word,it is necessary to train students’the thinking of the combination of numbers and shapes,train their thinking of logical-reasoning,improve the skills of visual imagination,implement the requirements of the mathematics curriculum standards of core literacy,improve the combination of numbers and shapes and internalize it into students’ core literacy.
