本文介绍了大学一年级学生的概念，关于“测量”。提供了一个教学序列，包括关于测量误差分析的理论讲座课程，然后是光学和电学的实验室工作。在实验室工作期间收集了数据。他们的分析表明，学生在一系列测量中建立了一个层次结构，并没有真正理解进行多个测量的必要性。他们中很少有人对置信区间的概念有深刻的见解。不区分随机误差和系统误差。一般的观点是，测量越多，结果就越“好”，而不理解这种“好”的本质。
This paper describes the conceptions of first‐year University students, about ‘measuring’. A teaching sequence has been provided, involving a theoretical lecture course on the analysis of measurement errors, followed by laboratory work in optics and in electricity. Data have been gathered during the laboratory work. Their analysis shows that the students establish a hierarchy in the series of measurements and do not really understand the need to make several measurements. Few of them have critical insight into the notion of confidence interval. Random and systematic errors are not distinguished. The general view is that, the more measurements one makes, the ‘better’ the result is, without understanding the nature of this ‘better’.
