Abstract Title: Difficulties of Selected Physics and General Science Students of Philippine Normal University in Electricity and Magnetism
Abstract: This study focuses on the identification of the students' difficulties in electricity and magnetism using the CSEM (Conceptual Survey on Electricity and Magnetism). It is a 32-question, multiple-choice test developed by Maloney,O?Kuma, Hieggelke, and Heuvelen(2001),to assess students' knowledge about topics in electricity and magnetism. Based on results of the study, the top three difficult items are items number 16, 21 and 31. The topics covered by these items are: Work, electric potential, electric field and force; Magnetic force; and Faraday?s Law respectively, and the competencies related to these topics are: identifying the conditions for electromagnetic induction to occur; identifying the direction of the magnetic field, magnetic force and induced current involved in electromagnetic induction using right-hand-rule; interpreting the graphs of the induced current and voltage in Faraday?s law experiments; describing the motion of a charge in uniform magnetic field; relating the directions of the motion of a charge, the magnetic force and the magnetic field; identifying the relationship of the electric potential energy, charge and electric field; comparing the amount of work needed and the magnitude of the electric field in each cases and identifying the electric force exerted by the field and identifying the relative magnitudes and directions of the electric force given certain cases. Findings were used as basis for the development of intervention materials.
