教学概念是进行判断、推理和建立定理的基础,清晰的概念是正确思维的前提,概念教学是数学教学的重要组成部分.而由常量数学过渡到变量数学是初中数学难关之一,因此,初中函数概念的入门学习尤为重要,下面是本人在教学中的一些尝试,请各位老师批评指正.1创设情景,生动有趣地引入 Concept of teaching is the basis of judgment, reasoning and establishing theorem, the clear concept is the premise of correct thinking, concept teaching is an important part of mathematics teaching, and the transition from constant mathematics to variable mathematics is one of the math difficulties in junior high school. Therefore, Introduction to function concepts is particularly important, here are some of my attempts in teaching, please criticize the teachers correct .1 create scenarios, vivid and interesting introduction
