函数是高中数学的重要内容之一,知识点多,难度大。由于函数本身具有复杂性和抽象性,学生理解起来比较困难,再加上指数函数是高中学习的第一种基本初等函数,学生由于对指数函数的概念、性质理解不透,对所学知识一知半解,模棱两可,做题错了一次又一次。教学不仅需要教师努力,学生也应该清楚地认识到自己在数学学习中常碰到的错误,并及时找到错误原因,避免再犯错。因此,本文就指数函数中学生常见的几种典型错解举例剖析,供参考。
Function is an important part of high school mathematics, knowledge, more difficult. Because of the complexity and abstraction of the function itself, it is difficult for students to understand it. Coupled with the fact that exponential function is the first basic elementary function of high school, students have a poor understanding of the concept and nature of exponential function. Ambiguous, do the wrong thing again and again. Teaching not only requires teachers’ efforts, but also students should clearly recognize the mistakes they often encounter in maths learning and find out the reasons for the mistakes in a timely manner to avoid making mistakes again. Therefore, this article analyzes some common misunderstanding examples of students in exponential function for reference.
