初中函数是初中数学中重要的基本概念之一,它揭示了现实世界中数量关系之间相互依存和变化的实质,是刻画和研究现实世界变化规律的重要模型。面对如此重要的学习内容,由于学生没有相应的认知基础,多数学生感到难以入门。为了解决这个矛盾,我在初中数学函数的教学中主要从以下几方面着手,现将我的体会总结如下:
The junior middle school function is one of the most important basic concepts in junior middle school mathematics. It reveals the essence of the interdependence and change between the quantitative relations in the real world and is an important model to describe and study the changing laws of the real world. Faced with such important learning content, most students find it hard to get started because students do not have a corresponding cognitive foundation. In order to solve this contradiction, I mainly begin from the following aspects in the teaching of math function in junior high school. Now I will summarize my experience as follows:
