对CUE评分标准的再思考:叠加原理

Re-thinking the Rubric for Grading the CUE: The Superposition Principle

Justyna P. Zwolak, Mary Bridget Kustusch, Corinne A. Manogue

摘要:

虽然电磁学(E&M)的研究已经进行了几十年,但高级部门的研究相对较新。科罗拉多大学开发了科罗拉多州高年级静电(CUE)诊断测试学生的理解的内容的高年级E&M课程的第一学期。虽然CUE上的问题以适当的方式涵盖了许多学习目标,但我们认为CUE的标题特别符合科罗拉多大学的主题和教学方法。我们建议,对规则的修改将允许更好地评估更广泛的教学计划。作为一个例子,我们强调一个问题,从CUE涉及叠加原理。使用俄勒冈州立大学和科罗拉多大学的数据,我们讨论了目前的标题的局限性,使用不同的分析方案比较结果,并讨论了评估学生的理解的影响。

英文摘要:

While introductory electricity and magnetism (E&M) has been investigated for decades, research at the upper-division is relatively new. The University of Colorado has developed the Colorado Upper-Division Electrostatics (CUE) Diagnostic to test students' understanding of the content of the first semester of an upper-division E&M course. While the questions on the CUE cover many learning goals in an appropriate manner, we believe the rubric for the CUE is particularly aligned to the topics and methods of teaching at the University of Colorado. We suggest that changes to the rubric would allow for better assessment of a wider range of teaching schemes. As an example, we highlight one problem from the CUE involving the superposition principle. Using data from both Oregon State University and the University of Colorado, we discuss the limitations of the current rubric, compare results using a different analysis scheme, and discuss the implications for assessing students' understanding.
