Research On Teaching Strategy Of Developing Senior High School Students’ Mathematical Modeling Literacy

Basic education curriculum carries the Communist Party’s educational policy and thought,and plays a key role in moral education.In 2017,The Mathematics Curriculum Standard for Senior High Schools(2017 Edition)proposed mathematical modeling literacy for the first time which became one of the six core literacy.In 2019,the senior high school mathematics textbooks in PEP version regard mathematical modeling activities and mathematical exploration activities as one of the four main lines.However,the author finds some unpleasant facts about mathematical modeling literacy in the real teaching after the overall observation.There are few mathematical modeling courses.The teachers have an unclear knowledge of it and the students have different levels of it.Therefore,the author investigates the problems arisen from the developing process of senior high students’ mathematical modeling literacy and the teachers’ educational practice,and puts forward some teaching strategies based on mathematical modeling literacy from the teacher’s perspective.After establishing the research ideas and research contents,the author consulted a large number of domestic and foreign literatures and designed a student questionnaire from the three aspects: cognition,emotion and volition.in order to know students’ cognition,emotion and will of mathematical modeling subjectively;Combined with the curriculum standard,the student test paper is designed to objectively understand the current level of students;Interviews with several teachers were conducted to understand the actual situation of teachers carrying out mathematical modeling courses and cultivating students’ mathematical modeling literacy.Through the survey,it is found that students generally affirm the significance and value of mathematical modeling.The level of "cognition,emotion and volition" of boys is higher than that of girls,and girls are more prone to fear and disgust.When the sophomores finish the senior high mathematics course,most of them can reach the high school graduation level,but there is still a certain distance away from the requirements of the college entrance examination.Combined with the questionnaire and test,it can be fully affirmed that secondary education has taken effect at this stage.However,when the author interviewed the teachers,they conveyed that under the existing evaluation mechanism,they did not pay enough attention to mathematical modeling literacy,lacked experience and resources,and mostly used traditional teaching methods.As a result,mathematical modeling teaching can not be carried out actively and effectively in senior high school.Based on the premise of analyzing these surveys,the research in terms of each teaching links deeply analyzes the new textbook,implements the teaching objectives of mathematical modeling,and raises strategies from four aspects: teaching plan,teaching content,teaching model and emotion quality.Firstly,it is found that 147 parts of the new compulsory textbooks have integrated with mathematical modeling literacy,which provides rich cases for the real teaching.Only when teachers bring it into the teaching plan and make good use of each lesson,can they implement the main goal;Secondly,This paper provides some teaching materials and suggests that senior high school teachers should adjust the teaching content and enhance the application of mathematics teaching;Thirdly,It is necessary to combine the teaching with information technology,for example graphic calculator,to realize mathematical "visualization" and invigorate mathematical modeling teaching;Fourthly,In teaching,we should start from the real world to the mathematical world,and then return to the real world,present the whole process of knowledge formation,add the emotion to the teaching,help students form a complete view of mathematics so that we can realize the educational value of mathematics teaching in senior high school.Finally,with the application of the strategy of the study,this paper designs the teaching case of the new lesson the basic idea and preliminary application of regression analysis,and expounds the five links: content analysis,analysis of students,teaching objectives(including educational objectives),teaching process and teaching reflection;at the same time,the paper also designs the teaching case of the exercise lesson solving mathematical modeling with the help of graphic calculator,and explains in detail the process of solving the problems for teaching practice.Furthermore,the rationality,validity and scientificity of the strategy is also verified.
