Abstract

The purposes of this study were to develop a learner activity-centered science class program, apply it to the fourth-grade elementary students, and analyze its effects on their attitude towards science, academic achievement, and concept sustainability. To this end, the content of the fourth-grade elementary subject related to 'volcanoes and earthquakes' was reorganized through 12 periods, and the class was divided into two groups. Then, general science class was applied to the comparative group, and the learner activity-centered science class program including writing, making, and expressing was applied to the experimental group. In order to compare the two groups regarding attitude towards science, academic achievement, and concept sustainability before and after the application, mind map data was collected and analyzed based on mind map grading criteria. As a result of the post-test, the two groups showed statistically significant differences in all the sub-factors of attitude towards science, that is, recognition, ability, value, and interest sustainability, especially in interest sustainability. As for academic achievement, as a result of the post-achievement test, the experimental group had higher average scores than the comparative group, and it also showed improved scores compared to the pre-achievement test results. In addition, as a result of the post-achievement test, both the two groups showed statistically significant results. In the concept sustainability test after the post-achievement test, the experimental group had higher average scores than the comparative group in the areas of center circle, branches, and expression, which were the evaluation criteria for the mind map analysis, and the two groups showed statistically significant differences in the areas of center circle and expression, except for branches. In conclusion, learner activity-centered science class turned out to be effective on students' attitude towards science, academic achievement, and concept sustainability. If the learner activity-centered science class program is actively introduced and used in actual educational sites, it is expected to contribute to improving related classes.

이 연구의 목적은 학습자 활동 중심 과학수업 프로그램을 개발하고, 초등학교 4학년 학생들에게 적용하여 학생들의 과학에 대한 태도, 학업성취도 및 개념 지속성에 미치는 영향을 분석하는 것이다. 이를 위하여 '화산과 지진'에 관련한 초등학교 4학년 교과 내용을 12차시에 걸쳐 재구성을 진행하였으며, 두 집단으로 학급을 나눈 다음 비교집단에는 일반적인 과학수업을 적용하였고, 실험집단에는 글쓰기, 만들기, 표현하기 등 학습자중심활동이 포함된 프로그램을 수업에 적용하였다. 적용 전과 후 두 집단에 과학에 대한 태도, 학업 성취도, 개념 지속성을 알아보기 위한 마인드맵의 자료를 수집하고 마인드맵 채점기준을 적용하여 분석하였다. 연구 결과, 실험집단과 비교집단의 사후 검사 결과 과학에 대한 태도의 하위영역인 인식, 능력, 가치, 흥미지속성에서 모두 통계적으로 유의미한 차이를 나타냈는데, 특히 흥미지속성에서 가장 차이가 큰 것으로 분석되었다. 학업성취도와 관련해서는 사후 성취도 검사 결과 실험집단이 비교집단보다 평균 점수가 높았으며, 사전 성취도 검사 결과와 비교할 때에도 실험집단은 평균 점수의 향상이 확인되었다. 또한 사후 성취도 검사 결과 두 집단은 통계적으로 유의미한 것으로 나타났다. 사후 성취도 검사 이후 실시한 개념 지속성 검사에서는 실험집단이 비교집단보다 마인드맵 분석의 평가 기준인 중심원, 가지, 표현 영역에서 모두 평균 점수가 높았으며, 가지 영역을 제외한 두 영역에서 모두 통계적으로 두 집단이 유의미한 차이를 보였다. 따라서 학습자 활동 중심 과학수업은 과학에 대한 태도, 학업성취도 및 학생들의 개념 지속성에 효과가 있었다. 학습자 활동 중심 과학수업을 실제 교육 현장에서 적극적으로 도입하고 활용한다면 교실수업을 개선시키는 데에 효과가 있으리라 기대된다.
