Research On The Present Situation And Cultivation Strategy Of Mathematical Operation Literacy Of Senior Three Students

Mathematical operation literacy is one of the six core literacy in the "General High School Mathematics Curriculum Standards(2017 Edition and 2020 revision)",it is closely related to the other five core literacy,which is one of the training goals of high school mathematics teaching.The development of students’ mathematical operation literacy has attracted the attention of front-line mathematics teachers and scholars.Moreover,senior three students have systematically learned the theoretical knowledge of senior high school mathematics and accumulated certain problem-solving experience.The number of math problems will be increased,and the scope of knowledge examined will be broader and more comprehensive.Therefore,the main purpose of this study is to find out the existing problems,influencing factors and main causes of problems on the basis of understanding the development status of mathematical operation literacy of senior three students,and put forward effective cultivation strategies.In order to understand the development status of mathematical operation literacy of senior three students and find out the existing problems,influencing factors and the main causes of problems,this study adopts the literature research method,the investigation method and the statistical analysis method.This study also constructs the evaluation framework of mathematical operation literacy of senior three students and the two-way questionnaire list suitable for this study,and prepares the pre-test paper and questionnaire of mathematical operation literacy.By sorting out and analyzing the pre-test paper and questionnaire,the correlation analysis is made on the current situation of students’ mathematical operation literacy.The results show that the overall performance of senior three students’ mathematical operation literacy is general and needs to be improved,and there is no significant difference between boys and girls in mathematical operation literacy performance.The existing problems are as follows: in the familiar mathematical situation,the students’ understanding of operand object appears certain deviation;students do not really master the algorithm,and it occurs the algorithm negative transfer;the students’ thinking is rigid,and it is difficult to innovate ideas;students’ arithmetic ideas are not complete,and the arithmetic process is chaotic and not standard;students mechanically memorize mathematical knowledge,which leads to the inability to use it flexibly.Non-intellectual factors,operational habits,operational methods,teacher-student relationship,teaching methods and students’ performance of mathematical operational literacy are positively correlated,and influencing factors are as follows: student factors include non-intellectual factors,operational habits,operational methods,and teacher factors include teacher-student relationship and teaching methods.Among them,operational method is an important factor affecting students’ mathematical operational literacy,while teacher-student relationship has a weak influence on students’ mathematical operational literacy and is not the main factor.Combined with influencing factors,the main causes of the problems are as follows: on the one hand,student factors include students’ interest in mathematics,self-efficacy,confidence and firm perseverance to complete complex problems,good arithmetic habits and arithmetic methods;on the other hand,teaching method of teachers includes teachers’ blackboard writing demonstration,teaching model and teaching concept.In order to solve the existing problems,the author puts forward five cultivation strategies combining with its main causes and carries out teaching practice.Five cultivation strategies are put forward: analyzing the essence of concept and understanding the operand;carrying on the meaning memorization and mastering the algorithm;flexible use of knowledge and exploring operational ideas;standardizing the operation process and obtaining the operation result;summarizing operational methods and improving operational literacy.Two teaching cases "arithmetic progression and geometric progression" and "the sum of sequence of number" are designed by selecting the content of sequence of number.Experimental class and control class are set for teaching practice to test whether the proposed cultivation strategies and teaching cases in this study are effective.By means of investigation method and statistical analysis method,it is concluded that there are significant differences in the performance of mathematical operation literacy between the experimental class and the control class,and the performance of mathematical operation literacy of the experimental class is better than that of the control class.This study focuses on the research of mathematical operation literacy of senior three students,constructs the evaluation framework of mathematical operation literacy of senior three students and the two-way questionnaire list suitable for this study,and uses these research tools to assess the current situation of mathematical operation literacy of senior three students,providing certain ideas for other scholars to conduct research.At the same time,two teaching cases based on cultivation strategies,"arithmetic progression and geometric progression" and "the sum of sequence of number",are designed to provide reference for front-line teachers in teaching.
