一项调查是在研究生教学开始时进行的，目的是调查学生对量子力学的理解。这项调查是在第一学期开始时对来自七所大学的202名选修一年级量子力学课程的物理学研究生进行的。我们还对15名刚刚完成一门课程的研究生或高级本科生进行了一对一的访谈，这些课程涵盖了调查中的所有内容。虽然一些大学的学生平均表现比其他大学好，但我们发现，学生在理解量子力学概念方面存在普遍的困难。困难通常是由于在一个环境中学习的概念过度概括到其他环境中，而这些环境并不直接适用。在区分密切相关的概念和理解量子力学的形式主义方面的困难是常见的。本研究的结果对量子博士研究生一年级的教师具有一定的指导意义。
A survey was developed to probe student understanding of quantum mechanics at the beginning of graduate instruction. The survey was administered to 202 physics graduate students enrolled in first-year quantum mechanics courses from seven universities at the beginning of the first semester. We also conducted one-on-one interviews with fifteen graduate or advanced undergraduate students who had just completed a course in which all the content on the survey was covered. Although students from some universities performed better on average than others, we found that students share universal difficulties understanding the concepts of quantum mechanics. The difficulties were often due to overgeneralizations of concepts learned in one context to other contexts where they are not directly applicable. Difficulties in distinguishing between closely related concepts and making sense of the formalism of quantum mechanics were common. The results of this study can sensitize instructors of first-year graduate quantum ph...
