| Six core qualities are proposed in the curriculum standards for general high school mathematics(2017 edition),among which the "mathematical operation" quality is the most basic and critical one.Therefore,the cultivation of students’ "mathematical operation" literacy has been widely concerned by researchers.However,these studies are limited to concentrate on the connotation of mathematical operations,existing problems,training strategies.In actual teaching activities,most teachers do not know how to accurately implement mathematical literacy.Therefore,it is urgent for teachers to know which factors mainly affect students’ mathematical operation literacy in the teaching process,so as to know which aspects to pay attention to in the teaching and better improve students’ mathematical operation literacy.This paper first describes the background of the problem and the previous research,clarify the main research problems,ideas,significance and methods;Secondly,the concepts related to "mathematical operation" literacy are explained;Thirdly,interview and questionnaire are used to obtain the current work of teachers to cultivate students’ "mathematical operation" literacy,Using the test method to obtain the students’ current "mathematical operation" literacy level,Through the analysis of AMOS,the main factors affecting students’ "mathematical operation" literacy were obtained.Finally,according to the main factors,this paper gives some Suggestions on how to improve students’ mathematical operation literacy in teaching.The research methods adopted in this paper are mainly divided into data collection methods and data analysis methods.Data collection methods include literature research,interview,questionnaire and test.Data analysis methods include encoding method and structural equation model method.Literature research method is to understand the research status and results of mathematical teachers’ training of students’ mathematical operation literacy,provide theoretical basis for this study,and provide guidance for the compilation of teachers’ questionnaires.Using the methods of interview and questionnaire,the work and activities of in-service senior high school teachers to cultivate students’ core qualities of mathematics are concluded.The degree of students’ current mathematical literacy under these factors is measured by means of tests.Through the structural equation model method,find out the main influencing factors of improving mathematical operation literacy.Through the establishment of structural equation,it is found through calculation that the positive factors that have a great influence on the mathematical operation literacy of high school students are: Detailed blackboard operation example process;For error-prone operations to clear reasoning;Improve the speed of students in class;Instruct students to compare the different solutions of one problem with many solutions of operational problems and seek for the optimal solution;Students are required to master the operation steps.The negative factors that have a great influence on the mathematical operation literacy of high school students are: Pay attention to the teaching of one problem with multiple solutions and one problem with multiple solutions;Make clear the concepts related to operations.According to the above main influencing factors,teaching Suggestions are given: First,in the classroom teaching process,the teacher must pay attention to the detailed blackboard operation example process.Second,the teacher must pay attention to the students easy to make mistakes in the calculation of the clearing.Third,the teacher must pay special attention in the class has the consciousness to enhance the student the computation speed.Fourthly,teachers should pay attention to guiding students to compare the different solutions of multiple solutions of operational problems and seek for the optimal solution.Fifth,the teacher must pay attention to requests the student to master the related operation step.Sixth,the teacher must reasonably use one question many solution and many questions one solution teaching strategy.Seventh,the teacher must grasp and the computation related concept explanation suitably. |
