Teaching Design And Practice Of Mathematical Modeling In Junior High School Based On The Second Class

In the field of basic education,whether in "Compulsory Education Mathematics Curricul um Standard(2011 Edition)" or "Ordinary Senior High School Mathematics Curriculum Stan dard(2017 Edition)",mathematical modeling is one of the core concepts or core literacy.How ever,in the process of teaching practice,due to the tight time of First Class and the heavy teac hing tasks,it is difficult to effectively implement mathematical modeling literacy.Therefore,based on Second Class this paper studies the teaching design and practice of mathematical modeling in junior high school.In order to explore the teaching path of mathematical modeling in junior middle school which is in line with the current teaching practice and connected with First Class teaching of mathematics,and finally promote the normalization of mathematical modeling teaching in jun ior middle school,the specific research questions in this paper are as follows:(1)Based on the overall design of junior high school mathematics modeling teaching in Second Class,constru ct an asymptotic teaching practice plan to cultivate students' mathematical modeling literacy;(2)Based on elementary structure and key points of junior high school mathematical modelin g teaching design in Second Class,explore the strategies of junior high school mathematical modeling teaching design in Second Class.Following the research ideas of demand analysis,theoretical conception,practical resear ch and principle summary,this study preliminarily constructs the overall arrangement of math ematics modeling teaching in junior high school based on the second classroom,explores the corresponding teaching design strategies,and conducts practical research.The specific results are as follows:(1)The paper initially constructs the junior high school mathematics modeling phased te aching practice framework based on Second class,and accumulates a number of useful teachi ng cases with reference significance.(2)Formed an effective strategy for junior high school mathematical modeling teaching design based on the second classroom,including: develop mathematical modeling teaching re sources with rich content and suitable difficulty;follow the typical process of mathematical m odeling to set up the inquiry task after class;synthesize evaluation methods to promote the de velopment of students' mathematical modeling literacy.
