论文摘要
我们调查了量子和统计力学核心课程在费米能量，费米 - 迪拉克分布和自由电子气体的总电子能量之后，他们在各自的课程中学习相关概念后，量子和统计力学核心课程在量子和统计力学核心课程中遇到的困难。通过为本科生进行书面概念和定量问题来探讨这些困难，并要求一些本科生和研究生回答这些问题，同时在一对一的个人访谈中大声思考。我们发现，在传统的基于讲座的教学之后，高级学生在这些概念上遇到了许多常见的困难。与一系列点击器问题接触，提高了学生的表现，但是在理解这些具有挑战性的概念方面，仍然可以提高他们的余地。
We investigated the difficulties that physics students in upper-level undergraduate quantum mechanics and graduate students after quantum and statistical mechanics core courses have with the Fermi energy, the Fermi-Dirac distribution and total electronic energy of a free electron gas after they had learned relevant concepts in their respective courses. These difficulties were probed by administering written conceptual and quantitative questions to undergraduate students and asking some undergraduate and graduate students to answer those questions while thinking aloud in one-on-one individual interviews. We find that advanced students had many common difficulties with these concepts after traditional lecture-based instruction. Engaging with a sequence of clicker questions improved student performance, but there remains room for improvement in their understanding of these challenging concepts.
