1设计说明1.1学情分析本设计所选的五道例题主要是面向中等学业水平的学生。对完成新课阶段学习的学生而言,函数的概念最容易被误解,准确而熟练的运算是重点,“读图”、建立函数模型解决基本的实际问题既是重点也是难点。1.2设计思想本设计旨在借助典型例题帮助学生深入理解函数的概念,进一步提高分析函数图像的能力;在建立函数模型解决实际问题的过程中提高模型意识和运算能力。基础复习的关键在于厘清基本概念之间的
1 Design Description 1.1 Analysis of the situation The design of the five examples selected mainly for middle school students. The concept of a function is most likely to be misunderstood by students who complete the new lesson, and accurate and proficient computing is the key point. It is both important and difficult to establish a functional model to solve basic practical problems. 1.2 Design ideas This design aims to help students to understand the concept of function with typical examples to further improve the ability to analyze the function of the image; to improve the model awareness and computing power in the process of establishing a functional model to solve practical problems. The key to a basic review is to clarify the basic concepts
