条件概率教法中的问题与改进

Problems and Improvements in the Teaching Methods of Conditional Probability

在条件概率教学过程中一般都忽略了关于条件事件的定义与刻画,这不仅会影响概率知识体系在教学流程安排中发挥相关作用的有效性,而且还会影响概率知识持续学习的效果。在给出条件事件定义的基础上,提供一个可参考的教学模式。这种安排能够使知识结构体系化,起到了承上启下的促进作用。因此,它对教学效果和教学质量产生的激励作用是可以期望的,同时也能实现知识的有效转化并形成应用力。

During the process of teaching Conditional Probability, the definition of conditional matter is usually neglected. It will make some influence for probability knowledge system to play relevant role in teaching flow, and also influence the efficiency of constant learning. A teaching method should be provided before the conditional matter is given, because it can systematize knowledge structure. Hence, it＇s helpful to promote the teaching efficiency and result, and also transform knowledge into application.
