摘要
为了充分调动学生学习概率的积极性并培养学生分析、解决问题的能力,在《正态分布》教学设计中,运用问题驱动和思维引导的教学理念,从高尔顿钉板实验出发,借助二项分布的极限分布——正态分布建立模型,学习正态分布的概率特性,引入中心极限定理,拓展正态分布的性质及应用.
For raising students’interest and developing their ability to analyze and solve problems,a problem-driven and thought-guided teaching design of’Normal Distribution’is proposed in this paper.First,through the Galton plate test,the limit of the binomial distribution,which is the normal distribution,is established.After given an account of probability characteristics of normal and standard normal distribution,the Central Limit Theorem is introduced to explain the relationship between binomial distribution and normal distribution.
