Abstract

In this study, the effects of a self-assessment on the students' science concept understanding and science-related attitudes were investigated. Student's perceptions towards the self-assessment were also examined. Five classes from a middle school in Gyunggi Province were chosen. Two of those classes were assigned to the control group that no self-assesment tool was applied to and the other 3 classes were assigned to the experimental group which a self-assess-ment tool developed for this study was applied to. The experimental group was further divided into two groups for imple-ment of two kinds of programs. One experimental group was provided some feedback such as solutions to problems and the other was not provided any type of feedback. The tests of science-related attitudes were administered before and after the instruction period. The science concepts understanding test was done only after the instruction. The results of this study were as follows. There were significant differences between the experimental group and control group in under-standing of scientific concepts. The enhancement of science-related attitudes was also higher for the experimental group. Providing feedback to students was more effective in the improvement of students' science-related attitudes. However, there were no significant differences in understanding of scientific concepts in relation to the feedback in experiment groups. From the above results, it was acknowledged thet self-assessment applied to the middle school science class showed considerably positive influences on the improvements of the understanding of scientific concepts and science-related attitudes.

이 연구에서는 자기평가가 중학교 학생들의 과학 개념 이해와 과학 관련 태도에 미치는 영향을 알아보았다. 연구대상은 자기평가를 실시한 3개 학급을 실험집단으로, 자기평가를 실시하지 않은 2개 학급을 통제집단으로 구분하였다. 실험집단은 자기평가를 실시한 후 피드백을 제공한 집단과 자기평가만 실시하고 피드백은 제공하지 않은 집단으로 구분하였다. 수업은 9주(20차시)에 걸쳐 실시하였고, 과학 개념 이해 검사는 사후, 과학 관련 태도 검사는 사전, 사후에 이루어졌다. 연구결과, 과학 개념 이해에서는 자기평가를 적용한 실험집단이 자기평가를 적용하지 않은 통제집단에 비해 더 향상된 것으로 나타났다. 또한 과학 관련 태도 향상에도 자기평가를 이용한 수업이 효과가 있는 것으로 나타났다. 실험집단 내에서 피드백을 제공한 집단은 피드백을 제공하지 않은 집단에 비해 과학 관련 태도 향상에는 통계적으로 유의미한 차이를 보였으나, 과학 개념 이해에서는 유의미한 차이를 보이지 않았다. 자기평가에 대해 학생들은 자기평가가 후속 학습에 영향을 주며, 학습 태도 향상에 도움을 준다고 인식하고 있었다.
