摘要

统计学中的样本平均数是一个非常重要的概念,其特性在计算机科学等其他领域也得到了广泛应用。本研究主要针对荷兰某大学计算机工程专业的学生,研究他们在学习统计学必修课程时对样本平均数概念及其特征的理解。本研究的目的是分析学生对样本平均数的基本结构、属性和应用的理解。我们为 97 名学生开发并使用了关于样本平均数的数字迷你课程,学生可以按照自己的进度应用这些概念。我们利用行动-过程-对象-模式(APOS)理论框架分析了七位参与者的访谈回答。大多数参与者都能表现出对样本平均数的过程概念的理解,只有少数人表现出对客体概念的理解。对样本平均数的理解不足阻碍了学生有效利用相关应用和属性的能力。这些发现意味着教育工作者应努力确保学生对样本平均数有正确的理解,以便他们能更好地处理相关应用。本研究的建议和进一步的研究思路也在此一并指出。

Conceptualizing the Sample Mean: Insights for Computer Engineering Students in the Learning Process
The sample mean in statistics is a concept of great importance, with its properties being extensively utilized in other areas, such as computer science. This research centers on the concept of the sample mean and its characteristics in a cohort of computer engineering students undertaking a required course in statistics at a university in the Netherlands. The objective of this study was to analyze students’ comprehension of the fundamental structure, properties, and applications of the sample mean. A digital mini-course on sample mean was developed and employed with 97 students, who had the option to apply the concepts at their own pace. The action-process-object-schema (APOS) theoretical framework was utilized to analyze the interview responses of seven participants. The majority of participants were able to demonstrate an understanding of the Process conception of the sample mean, with only a minority demonstrating an understanding of the Object conception. The lack of comprehension of the sample mean hindered students’ capacity to effectively utilize the associated applications and properties. These findings imply that educators should strive to ensure that students have a sound comprehension of the sample mean so that they are better equipped to work with related applications. Suggestions of this study and further research ideas are indicated.
