Purpose

The BEMA assesses students understanding of concepts in electricity and magnetism.

Population

The BEMA is commonly administered in introductory college electricity and magnetism courses (algebra-based and calculus-based) and is designed to be administered in upper division courses.

Typical Performance

We have not yet evaluated the data collected by the LASSO platform. Results reported in the literature report pretest scores from 23%-33% with an average of 26% and posttest scores from 38%-61% with an average of 50%.

Validity

Ding and colleagues published the BEMA in 2006.

Research

The research conducted with the BEMA is extensive. We recommend using Google Scholar and the citations listed under validation to find articles of interest.
