전구의 밝기에 대한 초등학생들의 사전개념 일관성 정도와 인지갈등 정도와의 관계 = Relation Between Degree of Consistency of Elementary Students` Preconceptions on the Brightness of Electric Bulb and Their Cognitive Conflict

다국어 초록 (Multilingual Abstract)

This study was to investigate the elementary students` preconception on the brightness of electric bulb and degree of consistency on their preconceptions. Participants were 160 students of fifth graders in Seoul area. They had already learned about the brightness of series circuit and parallel circuit of batteries. After they solved six problems in the same context, we provided them a pair of circuit which was an anomalous situation. And then they conducted CCLT (Cognitive Conflict Level Test). Elementary school students showed various preconceptions when they explained the light of bulb of two simple electric circuits. Many students consistently showed the scientific misconceptions like `the light of bulb of two simple electric circuits was that the more batteries and the fewer bulbs were brighter`. The level of consistency that students presented scientific misconceptions was grouped all of four, such as high, middle, low, and nothing. Therefore the higher scientific achievement they have, the higher consistency they have. As the students had high consistency level, they revealed high cognitive conflict level significantly. This high consistency will help them to change their preconception on the brightness of electric bulb and their cognitive conflict.
