论文摘要
我们在上层旋转第一量子力学课程中对学生的舒适度进行了调查。每周都会对学生进行调查，以调查学生的舒适度，其中学生以0--10的规模为自己分配了“不适”水平，并为他们的选择提供了书面解释。在整个学期中，每周全班平均不适水平有效地稳定，这表明该班级没有单个单位，尤其是刺痛，也没有特别容易。学生的书面答复是根据他们报道的不适感来编码的 - 数学，数学连接，物理和符号。这些类别的相对流行率在整个学期差异很大，这表明学生发现不同的单位提出了不同的挑战，并且其中一些挑战随着学期的进展而变得重要。在另一个机构的类似量子力学课程中，与学生在不同机构中对学生进行了半结构化访谈，为这些结果提供了更多的背景和洞察力。
We investigate student comfort with the material in an upper-division spins-first quantum mechanics course. Pre-lecture surveys probing students' comfort were administered weekly, in which students assigned themselves a "discomfort level" on a scale of 0--10 and provided a written explanation for their choice. The weekly class-wide average discomfort level was effectively constant over the semester, suggesting that the class found no single unit especially jarring nor especially easy. Student written responses were coded according to their reported source of discomfort---math, math-physics connection, physics, and notation. The relative prevalence of these categories varied significantly over the semester, indicating that students find that different units present different challenges, and also that some of these challenges fade in importance as the semester progresses. Semi-structured interviews with students in a similar quantum mechanics course at a different institution provided additional context and insight into these results.
