浅探初中数学二次函数的教学设计

AbstractQuadratic function as an important part of mathematics teaching in junior highschool,and it is the link of function learning in junior high school and senior highschool.In the classroom teaching of quadratic function,Through the design ofreasonable teaching design,make students systematically master the basic knowledgeof quadratic function,feel the mathematical thought of quadratic function,and maketeachers smoothly are the main problems studied in this paper.This paper firstintroduces the basic concept of teaching design,then puts forward several teachingsuggestions in the teaching of quadratic function,and finally discusses all the ideasfor the teaching design of junior high school mathematics quadratic function,anddesigns the teaching design of quadratic function,and explains in detail the designpurpose of each step in the teaching process,Some ideas of teaching design ofquadratic function are put forward.Key words:instructional design;quadratic function;Junior high schoolmathematics;classroom teaching
