Engineering students' concepts and conceptual difficulties in electricity and magnetism
Abstract
The study sought to determine engineering students' concepts as well as conceptual difficulties in electricity and magnetism. The Conceptual Survey in Electricity and Magnetism was used as the pretest and posttest. A sample of 80 students taking up Physics 214 during the 4th quarter of SY 2002-2003 was used as respondents of the study. Upon analysis of data, it was found that although there is a significant difference between the pretest and posttest scores, students encountered difficulties in dealing with specific concepts such as electric force and Newton's Law of Interaction, force in an electric field region, magnetic force and work and electric potential among others.
