本文描述了一项德尔菲研究，旨在调查专家认为哪些量子力学主题对于中学教学很重要，以及这些专家给出了哪些论据。对量子物理、数学、化学和生物物理学领域的专家进行了三份系列问卷调查（第一、第二和第三份问卷分别为 17、12、11；参与者人数因人员流失而发生变化）。该小组的几位专家（n=9）也接受了采访。结果表明，人们在对偶性、波函数和原子等重要主题上达成了共识。专家们的主题排名主要基于概念之间的关系以及他们认为是基础的量子力学主题。那些被认为不太重要的主题通常被描述为太困难或太复杂。
This article describes a Delphi study aiming to investigate which quantum mechanics topics experts consider to be important to teach at the secondary level, and what arguments these experts give. A series of three questionnaires was administered to experts in the fields of quantum physics, mathematics, chemistry and biophysics (n=17, 12, 11 for the first, second, and third questionnaires, respectively; the number of participants changed due to attrition). Several experts from this group (n=9) were also interviewed. Results show that there is consensus on the topics considered to be important, i.e. duality, wave functions and atoms. Experts mainly based their topic ranking on relations between concepts, and on what quantum mechanics topics they consider to be fundamental. The topics that were considered less important were often described as too difficult or too complex.
