论文摘要
测量不确定性和实验错误是本科物理实验室中教授的重要概念。尽管已经对学生对介绍性的经典力学实验室实验中的错误和不确定性的想法进行了广泛的研究，但关于学生思考量子力学中实验测量不确定性的研究相对有限。在这项工作中，我们使用半结构化访谈来研究高级物理学生对量子力学中两个常见的本科实验室实验的虚拟数据分布的解释，另一种是经典力学。为了分析这些解释，我们开发了一种编码方案，该方案根据他们认为造成不确定性的因素对学生的反应进行了分类，并区分了不同类型的不确定性（例如，不精确，不准确）。我们发现，我们研究的参与者表达了各种关于测量不确定性的想法，这些想法随上下文（经典/量子）和不确定性的类型而异。
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.
