项目反应理论的要素及其分析框架--以大学生天文学入门错误概念为例。I.星系

The Elements of Item Response Theory and its Framework in Analyzing Introductory Astronomy College Student Misconceptions. I. Galaxies

Andrej Favia, Neil F. Comins, Geoffrey L. Thorpe

摘要:

这是一系列论文中的第一篇,这些论文分析了在普遍存在天文学误解的领域中大学生的信仰。数据是通过管理大学天文学入门课程结束时分发的库存来收集的。在本文中,我们提出了项目反应理论(IRT)的基本数学,然后我们用它来探索与星系相关的概念。我们将展示IRT如何确定每个星系主题的难度。我们发现,星系空间分布的概念提出了最大的挑战,所有的星系主题的学生。我们还发现并提出了最合乎逻辑的顺序来教星系的主题作为观众的年龄的函数。

英文摘要:

This is the first in a series of papers that analyze college student beliefs in realms where common astronomy misconceptions are prevalent. Data was collected through administration of an inventory distributed at the end of an introductory college astronomy course. In this paper, we present the basic mathematics of item response theory (IRT), and then we use it to explore concepts related to galaxies. We show how IRT determines the difficulty of each galaxy topic under consideration. We find that the concept of galaxy spatial distribution presents the greatest challenge to students of all the galaxy topics. We also find and present the most logical sequence to teach galaxy topics as a function of the audience's age.
