Research On Teaching Design Of Mathematical Modeling Activity Lesson In Senior High School

Under the background of the rapid development of modern society,the importance of mathematics has become more and more important.Nowadays,the application scope of mathematics has been extended to all aspects of people's daily life.The society's demand for mathematics is mainly manifested in: to deal with specific problems in real life through the application of mathematical thinking and mathematical knowledge,so as to obtain higher social and economic benefits.Mathematics is an abstract cognition of real life,and mathematical modeling is a link between mathematics and the outside world and is also an important form of mathematical application.The senior high school mathematics curriculum standard(2017 edition)regards mathematical modeling literacy as a core mathematical literacy,and includes mathematical inquiry activities and mathematical modeling activities into the curriculum content,with a learning duration of 10 hours.In recent years,the research on the core literacy of mathematics has become a very hot topic,but few researches are aimed at mathematical modeling activities.As a kind of mathematics activity lesson,the research and practice of its teaching form and method,how to arrange the mathematics modeling activity class and how to design the teaching content are still in the exploration stage.In addition to theoretical guidance,the teaching of mathematical modeling activities must also involve students.The reason is that the implementation effect of this teaching activity is directly affected by students' mathematical modeling literacy level,while the latter will be improved by the implementation of the former.Therefore,it is necessary to cultivate the students' core qualities of mathematical modeling and carry out mathematical modeling activities course,and draw out specific teaching strategies.The writing structure of this paper includes six parts: The first part studies the senior high school mathematics modeling activities under the new curriculum standard reform,including the research background,ideas,contents,methods,significance and innovations.The second part introduces the relevant concepts and literature.First,it summarizes the history and current situation of the research on mathematical modeling at home and abroad,focusing on the analysis of the achievements,shortcomings and the correlation between the research to be launched and the existing research.The second is related concepts and theoretical basis.It mainly defines related concepts such as mathematical modeling,mathematical models,mathematical modeling literacy,mathematical activity classes,mathematical modeling activities and so on,and sorts outthe differences and connections between related concepts.Secondly,it studies the theoretical basis of mathematical modeling.It mainly analyzes the theoretical basis of mathematical modeling from the requirements of Curriculum Standard for mathematical modeling,Piaget's constructivism teaching theory,Freudenthal's mathematical education theory and metacognition theory.The third part focuses on the analysis of the current situation of the development of mathematical modeling activities in senior high schools and the existing problems in practical teaching.The fourth part is based on the high school mathematics modeling activity teaching present situation,unifies the related literature,carries on the design to the high school mathematics modeling activity class,and gives the teaching strategy.The fifth part is a detailed demonstration of teaching lessons.The sixth part is the research conclusion and reflection of this article,and puts forward the research prospect based on the author's research deficiency.
