摘要

理解测量的不确定度是大学物理实验课程一项重要的教学目标。在大学物理实验绪论课中，准备了两个版本的不确定性教学方式:即有无测量数据的图形化展示。课程结束后，对学生进行测试，研究数据的图形化展示是否能够提高学生对不确定度的理解。结果表明，有图形展示的班级学生比没有图形展示的班级学生得分更高。图形表示有助于数据的可视化，在进行测量数据分析时减少了学生的认知负荷，因此应该在教学中积极推广使用。

Abstract:

Making students understand the uncertainty of measurements is an important pedagogical goal of university physics experiments． In the introductory college physics laboratory course，two versions of the teaching approach are prepared:namely，with and without graphical presentation of measurement data．At the end of the course，students were tested to investigate whether the graphical presentation of data improves students’ understanding of uncertainty． The results showed that students in classes with graphical representations scored higher than students in classes without graphical representations． Graphical representations help visualize data and reduce the cognitive load on students when performing analysis of measurement data，and therefore should be actively promoted for use in teaching．

Key words: uncertainty measurement error\data visualization cognitive load
