Research On The Cultivation Of Mathematical Modeling Literacy In High School Mathematics Teaching

This paper is a special research on the teaching principles,methods,practices and training strategies of high school mathematics teaching based on mathematical modeling literacy.Mathematical modeling literacy is one of the important factors to test whether middle school students can use mathematical knowledge to solve problems in life.To master the core literacy of mathematical modeling is an inevitable requirement for middle school students in the new era of the 21 st century.Mathematical modeling is one of the important research topics in the field of mathematical education.This paper attempts to solve the following two problems.Question 1:the understanding of mathematical modeling literacy of the current mathematics teachers and the level of mathematical modeling literacy of high school students;Question 2: what kind of teaching methods and training strategies can better cultivate students' mathematical modeling literacy? In this paper,literature analysis,questionnaires,tests and other methods are used to study the current situation of mathematical modeling literacy in high school mathematics teaching.Then,under the guidance of mathematical modeling literacy theory,the teaching principles,methods and cultivation strategies of mathematical modeling literacy in teaching are proposed.Finally,the teaching practice research is carried out.The basic content of this paper is as follows: first,introduce important aspects of the paper including the background,methodologies,significance,etc.Then the concept of mathematical modeling literacy is fully explained and the relationship between mathematical modeling literacy and problem-solving abilities are entirely given.The mathematical modeling qualities are obtained through exploration: essential modeling characters and key modeling abilities.Secondly,design the questionnaire and the test paper,and then carry out a survey on the status of mathematical modeling literacy of the respondents.And analyze the results from the survey.Third,four teaching principles based on mathematical modeling literacy(" combining theory with practice ","from simple to deep,from simple to difficult","teamwork,clear division of labor","proximate development zone")and four teachingmethods(direct method,image method,general rule method,approximation method)are proposed.According to related achievements,put forward the cultivation strategies of mathematical modeling literacy : "from the perspective of the normal teaching,develop essential modeling characters ","from the mathematical modeling of thematic teaching activities,improve the key modeling abilities","value model classifications,and improve the key modeling abilities","modeling attaches great importance to the teachers' training,improving teachers' teaching abilities","attaches great importance to the development of teaching materials,enabling teachers to write the school-based curricula".Fourth,the teaching methods,teaching principles and training strategies proposed will be implemented in practice.After practice,case analysis and reflection will be conducted and the analysis of after-class test paper will be conducted.Finally,focus on the conclusions,shortcomings and possibilities of this paper.
