# Common Misunderstandings and Challenges in Learning Gauss’s Law in a Junior Level Electromagnetic Engineering Course

## Abstract

Common misunderstandings when learning Gauss’s Law in a college junior level electromagnetic engineering course are identified by observing normal course assessments and conducting one on one student interviews. Additionally, the extent to which students in this course struggle to translate prior mathematics is investigated by codifying student performance on normal assessments using a rubric developed by the authors based on Accreditation Board for Engineering and Technology (ABET) Criterion 3 (a) and (e). Five misconceptions are identified, three of which agree with physics educational literature, as well as a need for better scaffolding the translation of calculus II and multidimensional calculus material. Future work and possible intervention strategies are discussed.
