案例式教学在心理统计教学中的应用——以假设检验的两类错误为例

Application of Case Teaching in the Course of Psychological Statistics:Taking the Two Types of Errors in Hypothesis Testing as an Example

随着心理学与多种学科的交叉融合,科学的研究方法与技术在心理学领域中得到了越来越普遍的应用,对数据的分析与统计也成了心理学专业学生必备的一项重要技能。但对于本科生来说,在多种心理学课程中,心理统计学更为抽象,难以理解与掌握。以假设检验的α错误与β错误两个重要的基础概念为着眼点,先从最易于理解的刑事案件审判入手,再对两个t检验例子进行进一步的研究,阐述了案例教学在心理统计学教学中的应用,说明了案例式教学是促进学生理解和运用心理统计学知识的重要方式。

As the interdisciplinary integration of psychology with various disciplines,scientific research methods and techniques have been more and more widely used in the psychology research.Data analysis and statistics have become important skills for students majoring in psychology.However,for undergraduates,Psychological Statistics is more abstract and difficult to understand and master when compared with other psychology courses.By taking alpha and beta errors in hypothesis testing as an important example and using a criminal case trial and two t-test examples as the teaching cases,this paper elaborates the application of teaching cases in the teaching of Psychological Statistics.The results illustrates that case teaching is an important way to promote students to understanding and use the knowledge of Psychological Statistics.
