优化新概念教学提升大学生探究能力——以“数学期望”教学实践为例

Optimizing the New Concepts Teaching and Improving the Exploring Ability of College Students:Taking the Teaching Practice of"Mathematical Expectation"as an Example

数学期望是概率论课程中一个十分重要的知识点,是随机变量系列数字特征之“魂”.本文展示了在引入“数学期望”新概念教学过程中的一点尝试性实践与思考,主要体会是凸显其“内涵”,引导学生积极探究思索,化难为易,达到深刻理解并熟练运用之教学目的.

"Mn Mathematical expectation"is a very important knowledge point in the course of probability theory,it is the"soul"of the digital characteristics of random variable series.This paper shows some tentative practice and thinking in the teaching process of introducing the new concept of"Mn mathematical expectation".The main experience is to highlight its"connotation",actively guide students to explore and think,turn difficult into easy,and achieve the teaching purpose of deep understanding and skilled use.
