浅探初中数学一次函数的教学设计

AbstractThe primary function is very important,in junior middle school mathematics.It isthe opening chapter of the whole function field,so the mastery of the primaryfunction directly affects the subsequent learning of other functions.In the course ofteaching a function,how to carry out teaching design can improve the quality ofteaching,so that students can truly understand the concept of functions and master thebasic skills of solving problems with functions.This is the main research problem ofthis article.This article firstly makes a comparative analysis of the primary functionsections in the three major textbooks,and analyzes the students learning situation andknowledge structure,and then formulates the unit goals of the function chapteraccording to the students'cognitive level.,The instructional design of linear functionis given with reference to the teaching standards.I hope it can help in the teaching oflinear functions.Key words:Junior high school mathematics.Linear function,instructional design.
