用于评估学生对入门热力学理解的概念性选择题调查工具的开发与验证

Development and validation of a conceptual multiple-choice survey instrument to assess student understanding of introductory thermodynamics

Mary Jane Brundage, Chandralekha Singh

AI总结:

本文开发并验证了STPFaSL-Long概念性选择题工具,通过拆分短版题目并去除选项中嵌入的替代概念,在多种教学情境下评估入门热力学学生的概念理解。

摘要:

我们讨论了名为“热力学过程与第一、第二定律调查——长版”(STPFaSL-Long)的概念性选择题调查工具长版的开发与验证,该工具适用于入门物理课程。此版本的调查工具是先前开发并验证过的原始短版的加长版本。两个版本的调查工具中提出的所有问题情境的19个背景(包括确切措辞)完全相同,长版与短版工具之间的区别仅在于选择题选项。具体而言,在长版调查工具中,学生选择的四个选择题选项中未明确嵌入任何替代概念,而短版调查工具中某一项目在给定背景下提出的问题被拆分为若干项目,分别聚焦于例如不同的热力学变量。在长版调查工具开发与验证完成后,最终版本在12个不同的线下课堂(来自四所不同机构)中施测,学生在课堂上由教师监考,在纸质答题卡上作答;同时也在12个不同的线下课堂(来自五所不同机构)中施测,学生在两小时内通过Qualtrics在线作答。该长版调查工具在传统讲授式教学前后,分别施测于各类传统教学的基于微积分和基于代数的入门物理课程中的学生。此外,该工具还施测于接受传统教学的高年级物理专业本科生和博士生,用于基准测试目的。

英文摘要:

We discuss the development and validation of the long version of a conceptual multiple-choice survey instrument called the Survey of Thermodynamic Processes and First and Second Laws-Long (STPFaSL-Long) suitable for introductory physics courses. This version of the survey instrument is a longer version of the original shorter version developed and validated earlier. The 19 contexts including the exact wording of all of the problem situations posed in the two versions of the survey instrument are identical and the difference between the long and short versions of the instrument is only in the multiple-choice options. In particular, in the longer version of the survey instrument, there are no alternative conceptions explicitly embedded in the four multiple-choice options students choose from and the questions asked in a given context in one item of the shorter survey instrument were split into several items focusing, e.g., on different thermodynamic variables. After the development and validation of the longer version of the survey instrument, the final version was administered in 12 different in-person classes (four different institutions) in which students answered the questions in-class on paper scantron forms with the instructor as the proctor and 12 different in-person classes (five different institutions) in which students answered the questions online on Qualtrics within a two-hour period. This longer version of the survey instrument was administered to introductory physics students in various traditionally taught calculus-based and algebra-based classes before and after traditional lecture-based instruction in relevant concepts. It was also administered to upper-level undergraduates majoring in physics and Ph.D. students taught traditionally for bench marking purposes.
