摘要

我们开发了物理定量素养量表(PIQL),作为在介绍性物理主题背景下测量学生定量素养的工具。我们提出了各种定量分析的结果,用于建立个人项目和PIQL作为一个整体的有效性。我们展示了如何检查经典测试理论分析、因素分析和项目反应曲线的结果,从而决定是否包含、删除或修改项目。我们还讨论了选择包含多项选择/多项回答项目如何影响我们的分析选择和对结果的解释。我们有信心,最新版本的PIQL是一个有效和可靠的工具,用于测量学生的物理定量素养在微积分为基础的物理入门课程在我们的主要研究站点。需要更多的数据来确定其在其他机构和其他课程中使用的有效性。

Toward a valid instrument for measuring physics quantitative literacy
We have developed the Physics Inventory of Quantitative Literacy (PIQL) as a tool to measure students' quantitative literacy in the context of introductory physics topics. We present the results from various quantitative analyses used to establish the validity of both the individual items and the PIQL as a whole. We show how examining the results from classical test theory analyses, factor analysis, and item response curves informed decisions regarding the inclusion, removal, or modification of items. We also discuss how the choice to include multiple-choice/multiple-response items has informed both our choices for analyses and the interpretations of their results. We are confident that the most recent version of the PIQL is a valid and reliable instrument for measuring students' physics quantitative literacy in calculus-based introductory physics courses at our primary research site. More data are needed to establish its validity for use at other institutions and in other courses.
