Abstract

In this study, we investigated the effects of explicit and reflective instruction about nature of science (NOS) using episodes from the history of science upon students' understanding about NOS, achievement, and enjoyment of science lessons. Four classes of ninth graders (N=129) at a coed middle school were divided into the control and the treatment groups. The students were taught about the composition of material for 11 classes. Before the instruction, most of the students in both the control and the treatment groups held naive views about NOS. After the instructions, the views about NOS of the control group students did not change, whereas the students in the treatment group held more adequate views about NOS. The high-level students in the treatment group showed more adequate views about NOS than the low-level students. However, there were no significant differences between the test scores of the two groups in the achievement and the enjoyment of science lessons.

이 연구에서는 과학사 소재를 활용한 명시적 반성적 과학의 본성(NOS) 수업이 학생들의 과학의 본성에 대한 이해, 학업 성취도, 과학 수업에 대한 즐거움에 미치는 효과를 조사하였다. 남녀 공학 중학교 3학년 4학급(129명)을 통제 집단과 처치 집단으로 배치하였다. '물질의 구성' 단원에 대하여 11차시 동안 수업을 실시하였다. 수업 처치 전, 두 집단의 학생들은 대부분 과학의 본성에 대해 부적절한 견해를 지니고 있었다. 수업 처치 후, 통제 집단 학생들의 과학의 본성에 대한 견해는 변하지 않았으나, 처치 집단의 학생들은 과학의 본성에 대해 보다 적절한 이해를 나타내었다. 처치 집단의 상위 학생들은 하위 학생들보다 과학의 본성에 대해 보다 적절한 관점을 지니게 되었다. 그러나 학업성취도와 과학 수업에 대한 즐거움 검사에서는 두 집단 간 점수 차이가 통계적으로 유의미하지 않았다.
