Direct linkEaton, Philip; Johnson, Keith; Barrett, Frank; Willoughby, Shannon – Physical Review Physics Education Research, 2019
For proper assessment selection understanding the statistical similarities amongst assessments that measure the same, or very similar, topics is imperative. This study seeks to extend the comparative analysis between the brief electricity and magnetism assessment (BEMA) and the conceptual survey of electricity and magnetism (CSEM) presented by…
