This is the third highest level of research validation, corresponding to at least 3 of the validation categories below.
Research Validation Summary
Based on Research Into:
- Student thinking
- Student interviews
- Expert review
- Appropriate statistical analysis
- At multiple institutions
- By multiple research groups
- Peer-reviewed publication
The multiple-choice questions on the EMCA were developed by a group of five faculty members based on their experience teaching the relevant topics. The EMCA was given to over 200 algebra-based and calculus-based second-semester introductory physics students, and appropriate statistical analyses of reliability, difficulty and discrimination were conducted. Reasonable values were found. Scores for men and women were similar.

Average scores and standard deviation for pretest, post-test, and normalized gain in introductory electromagnetism courses at Sienna College and George Washington University (GWU). The Sienna College algebra-based course has an emphasis on topics relevant to life sciences and is "taught in a traditional lecture style interspersed with students completing preassigned problems on the board during class." The Sienna College calculus-based course is taught with "a mix of short lectures frequently interspersed with think-pair-share questions and other mini problems." The GWU course is taught using a SCALE-UP model. From McColgan et al. 2017.
The latest version of the EMCA, released in 2015, is version 1.
