Instructional strategies that focus on improving student understanding of these concepts should take into account these difficulties. ![]() The difficulties are often due to over‐generalization of concepts learned in one context to other contexts where they are not directly applicable and difficulty in making sense of the abstract quantitative formalism of quantum mechanics. We find that students share universal difficulties about fundamental quantum mechanics concepts. undergraduate students who had just finished a course in which all the content on the survey was covered. We also conducted one‐on‐one interviews with fifteen graduate students or advanced. The survey was administered to 202 graduate students in physics enrolled in first‐year quantum mechanics courses from seven different universities at the beginning of the first semester. We developed a survey to probe student understanding of quantum mechanics concepts at the beginning of graduate instruction.
