Evaluating an electricity and magnetism assessment tool: Brief electricity and magnetism assessment

The Brief Electricity and Magnetism Assessment BEMA , developed by Chabay and Sherwood, was designed to assess student understanding of basic electricity and magnetism concepts covered in college-level calculus-based introductory physics courses. To evaluate the reliability and discriminatory power of this assessment tool, we performed statistical tests focusing both on item analyses item diffi...

Hands- and Minds-on Electricity and Magnetism

The paper describes several interesting school physics experiments from the area of electricity and magnetism found in foreign journals. These experiments may serve as an inspiration for development of similar school physics experiments or modified versions of experiments and for quantitative measurements on such experiments (which are often used just as qualitative experiments in our school pr...

Transforming Upper-Division Electricity and Magnetism

We have transformed an upper-division electricity and magnetism course for physics and engineering majors using principles of active engagement and learning theory. The teaching practices and new curricular materials were guided by the results of observations, interviews, and analysis of student written work to identify common student difficulties with the content. We first established explicit...

A new connection between electricity and magnetism

Electricity arises from the flow of electron charge, ferromagnetism from the ordering of electron spins. The interactions between electricity and ferromagnetism have been crucial to our technological development over the last centuries: the magnetic fields generated by electrical currents and the voltages generated by moving magnets are two cornerstones of our modern lifestyle. Important applic...
