The "Brightness Rules" Alternative Conception for Light Bulb Circuits
Bryan, Joel A.; Stuessy, Carol
Physics Education, v41 n6 p522-531 Nov 2006
An alternative conception for the observed differences in light bulb brightness was revealed during an unguided inquiry investigation in which prospective elementary teachers placed identical bulbs in series, parallel, and combination direct current circuits. Classroom observations, document analyses, and video and audio transcriptions led to the discovery of this alternative conception, appropriately christened "Brightness Rules". Assessments administered three weeks after the activity confirmed that several prospective teachers maintained the "Brightness Rules" conception even after instructor-led intervention. Implications of the discovery of this alternative conception are discussed with respect to a previously administered assessment question that could not identify the presence of this alternative conception.
