학생의 선개념과 탐구 기능이 전기 실험 결과의 해석에 미치는 영향

다국어 초록 (Multilingual Abstract)

This study primary aim is to investigate students` responses to experimental results which conflict with their preconceptions regarding electrical circuits. Eighty-eight students of both sexes were randomly selected from a science high school in Korea. They were questioned about their preconceptions regarding an electric circuit, and sixty-eight students with relevant misconceptions were selected. These students were presented with experimental results obtained by some other experimenter, and asked to interpret these results. The second aim of this study is to explore how students` responses vary according to the type of inquiry-skills required to obtain the result. To do this, two type of experimental results were developed: one obtained by observation and the other obtained by controlling variables. We found that many students doubted results for the simple reason that they conflicted with their preconceptions. They rejected results by mentioning other factors which could have affected the result, or simply by reiterating their preconceptions. This behaviour varied considerably by inquiry-skill type. 41% of students rejected conflictual result obtained by observation, but only 6% of students rejected results obtained by controlling variables.
