学生对量子力学与经典力学中实验测量不确定性来源的推理

Student reasoning about sources of experimental measurement uncertainty in quantum versus classical mechanics

Emily M. Stump, Courtney L. White, Gina Passante, N. G. Holmes

摘要:

测量不确定度和实验误差是大学物理实验教学中的重要概念。虽然学生对经典力学实验室实验中的误差和不确定性的看法已经得到了广泛的研究,但对学生对量子力学实验测量不确定性的看法的研究相对有限。在这项工作中,我们使用半结构化的采访,研究高等物理学生的解释虚构的数据分布从两个常见的本科实验室实验中的量子力学和一个经典力学。为了分析这些解释,我们开发了一个编码方案,根据学生认为哪些因素会产生不确定性,并区分不同类型的不确定性(例如不精确,不准确)对学生的反应进行分类。我们发现,我们研究的参与者表达了各种各样的关于测量不确定性的想法,这些不确定性随着上下文(经典/量子)和不确定性的类型而变化。

英文摘要:

Measurement uncertainty and experimental error are important concepts taught in undergraduate physics laboratories. Although student ideas about error and uncertainty in introductory classical mechanics lab experiments have been studied extensively, there is relatively limited research on student thinking about experimental measurement uncertainty in quantum mechanics. In this work, we used semi-structured interviews to study advanced physics students' interpretations of fictitious data distributions from two common undergraduate laboratory experiments in quantum mechanics and one in classical mechanics. To analyze these interpretations, we developed a coding scheme that classifies student responses based on what factors they believe create uncertainty and differentiates between different types of uncertainty (e.g. imprecision, inaccuracy). We found that participants in our study expressed a variety of ideas about measurement uncertainty that varied with the context (classical/quantum) and the type of uncertainty.
