The design and evaluation of an instructional sequence on Ampere's law

摘要

This paper describes the design, implementation, and evaluation of an instructional sequence intended to improve student understanding of Ampere's law among engineering students taking introductory physics. Participating students performed better on qualitative and quantitative test questions about Ampere's law than students in a similar class that devoted the same amount of time to the topic but followed traditional instruction. The results suggest that the strategy employed in the sequence can help students to apply and explain the relation between electrical currents and magnetic fields.
