본 연구는 학생들의 과학개념 형성에 효율적인 프로그램으로 활용될 ‘과학사를 통한 과학적 탐구과정 중심의 교수학습 자료’를 개발하고, 이를 학생들에게 적용하여 그 효과를 평가할 목적으로 수행되었다. 특히 본 연구에서 수행된 과학적 탐구과정의 적용 예는 지질연대에 대한 개념이다. 본 연구에서는 역사적인 검정과정을 경험한 다양한 과학적 설명 또는 이론 가운데, 지질연대에 대한 개념을 중심으로 교수학습 자료를 개발하고, 이 자료를 토대로 학생들의 개념발달에 미치는 효과를 평가하였다. 본 연구에서 사용된 과학사적 교수학습 자료에 대한 효과를 검증하기 위하여 이를 고등학교 2학년 학생들에게 적용하였다. 검증을 위하여 학생들을 실험반과 비교반으로 나누어 실험반에 과학사적 수업을, 비교반에 전통적 수업을 실시하고 그 결과를 비교 분석하였다. 또한 학생들 스스로와 교사들이 생각하는 학생들의 지질연대 개념에 대한 이해도를 알아보기 위하여 설문조사를 실시하고 그 결과를 분석하였으며, 이들 결과를 평가문항 작성 자료로 활용하였다. 본 연구 결과, 실험집단(6.39)이 비교집단(5.00)보다 평균 점수가 높게 나타난 것으로 보아 과학사적 수업이 효과가 큼을 알 수 있었다. 따라서 과학사적 교수학습 방법이 학생들의 지질연대 개념에 대한 오개념을 치유하는데 효과가 있었으며, 수업 연계성으로 인하여 개념 확립에 도움을 주는 것은 물론 평소 개념이 부족하다고 느끼던 학생들도 쉽게 개념 변천 과정에 동참할 수 있었다.

Development of Teaching and Learning Materials Based on History of Science for Students' Creativity The purpose of this study was to develope of an instructional model and materials based on the programming of the historical science teaching model for the fostering creativity. Especially, the study showed how the history of science can be used as a means for improving students' geological time misconception. Students' understanding for geological time conception and teaching-learning process for geological time were investigated by questionnaires(62 students in Daegu city and 17 science teachers in all over the country answered). It proved out that students couldn't fully understand the concept of geological time after learning geological time and showed many misconceptions. To compare the effect of the teaching method guided by history of science with the traditional teaching method for Earth‘s age conception, 61 students in two classes in the second grade high school in Daegu city were picked out. Teaching method guided by history of science to experimental group(31 students) and the traditional teaching method to control group(30 students) were applied. As a result of evaluation, experimental group(63.9 %) which took the teaching method guided by history of science was better than normal group(50.0 %) just after class. From this results, it is sure that the effect of the teaching method guided by history of science was better than the traditional teaching method in the teaching-learning process of geological time conception. Also there was the effect of improvement in geological time misconception by putting the teaching method guided by history of science into classes.
