Research On The Teaching Design Of Infiltrating Model Thought In Junior Middle School Mathematics Teaching

Due to the "compulsory education mathematics curriculum standards(2011Edition)" put "model thinking" into the top ten "core concepts",primary and secondary schools pay more attention to the cultivation of students' model thinking.In this paper,taking the textbook of the first volume of the eighth grade of Beijing Normal University edition as an example,we deeply study how to design the teaching design,so as to better infiltrate the idea of model into the middle school mathematics classroom teaching,and comprehensively improve the students' application ability of mathematical knowledge.Firstly,this paper uses the method of literature analysis to collect and sort out the relevant research situation of domestic scholars on the application of model thinking in junior high school mathematics,and discusses the necessity of the application of model thinking in junior high school mathematics classroom teaching.Secondly,through the way of questionnaire survey,from the four aspects of mathematical model concept,mathematical model in life,the application of mathematical model in classroom learning and in life,we know that the eighth grade students in our school don't know much about the idea of mathematical model and lack of understanding and application of mathematical model.Then,based on the theory of constructivism and Bolia's theory of problem solving,combined with the investigation of the idea of infiltration of mathematical model,this study puts forward the teaching design method of infiltration of model thought in junior middle school mathematics teaching,that is,creating the scene,perception model thought;Guide the inquiry,experience the model thought;Connecting with practice,applying model thought;Expand practice and test model ideas.Finally,on the status of the junior middle school mathematics,teaching target,content,structure and learning is analyzed,such as in Beijing normal university version of the mathematics teaching material the days of the eighth grade,for example,select "number and algebra","graphics and geometry","probability and statistics","comprehensive and practical" four plate part of teaching design and make a case analysis.
