离散型随机变量的数学期望的课堂教学设计

The Classroom Teaching Design of Mathematical Expectation of Discrete Random Variables

数学期望是随机变量一个重要的数字特征,在概率论与数理统计占有重要的作用。本文就以离散型随机变量的数学期望为主题展开,浅谈如何在课堂中让学生掌握数学期望的本质概念,并结合例题让学生了解到知识的应用性,学以致用。

The mathematical expectation of random variables is an important feature, plays an important role in the theory of probability and statistics. This paper focuses on the mathematical expectation of a discrete random variable as the theme, the essence of concept in the classroom discussion on how to make the students master the mathematical expectation, and combined with examples to enable students to understand the application of knowledge.
