BEMA (Brief ElectroMagnetism Accessment) tests were conducted for undergraduate students in introductory electromagnetism courses at Texas A&M University (TAMU) from 2014 - 2017 to assess students performances. A total of 3480 students participated and more than 6000 test scores are collected. The present study used a part of the data to investigate the BEMA performance with these scores taken prior to and after the class using the statistical measures based on the classical test theory. Item difficulty index, item discrimination index, point biserial coefficients and so on obtained from the TAMU data agree with the results reported by various research groups in past, and showed the test is statistically reliable. Thus, it is confirmed that administering the BEMA test is beneficial for assessing students learning of undergraduate electromagnetism at university classes.

Join us in exploring emergent themes in PER as a scholarly endeavor and as a research community!  Since its inception, PER has served as a confluence of discipline, theory, research methodology, practice, and application.  How have these facets and the interplays among them been fruitful for physics education globally, regionally, locally, or otherwise?  And, how have our successes and interactions influenced the very nature of PER itself?
Following the lead of AAPT for the summer meeting, PERC 20/20 was virtual. Enjoy browsing the content.
