尽管概念清单是物理和天文学教育界最常用的工具之一，但很少使用项目反应理论 IRT 对其进行评估。当 IRT 模型拟合数据时，它们会提供与样本无关的项目和人员参数估计。 IRT 还可以提供一种衡量学生学习收益的方法，从而规避 Hake 标准化收益的一些已知问题。在本文中，我们回顾了 IRT 的要点，同时将其应用于明星地产概念清单。我们还使用 IRT 来探讨一项重要的心理测量学辩论，该辩论很少受到物理学和天文学教育研究人员的关注：当我们说我们“测量”心理过程时，我们的意思是什么？这个问题引导我们使用 IRT 来解决构成本文标题的挑衅性问题：概念清单实际上衡量什么吗？
Although concept inventories are among the most frequently used tools in the physics and astronomy education communities, they are rarely evaluated using item response theory IRT . When IRT models fit the data, they offer sample-independent estimates of item and person parameters. IRT may also provide a way to measure students’ learning gains that circumvents some known issues with Hake’s normalized gain. In this paper, we review the essentials of IRT while simultaneously applying it to the Star Properties Concept Inventory. We also use IRT to explore an important psychometrics debate that has received too little attention from physics and astronomy education researchers: What do we mean when we say we “measure” a mental process? This question leads us to use IRT to address the provocative question that constitutes the title of this paper: Do concept inventories actually measure anything?
