과학교육에서 효과적인 과학 수업을 위하여 과학사 도입의 중요성이 계속 강조되어 왔다. 이에 따라 과학 교과서에는 많은 과학사 자료가 사용되고 있다. 하지만 과학 교과서에 사용된 과학사 자료가 어떤 유형과 맥락에서 어떠한 역할을 하고 있는 지에 대한 면밀한 분석은 이루어지지 못한 실정이다. 이에 본 연구에서는 선행 연구와 관련 문헌 분석을 통해 과학 교과서에 사용된 과학사 자료를 분석하기 위한 3차원 틀을 개발하고, 이를 제 7차 교육과정의 과학 교과서 지구과학 내용을 대상으로 적용하였다. 개발된 분석틀은 수업맥락, 역할, 제시유형의 3개 차원으로 구성된다. 수업맥락 차원은 흥미, 사회-문화적, 인식론적, 개념적 맥락의 4가지 영역으로 세분되며, 제시유형 차원은 에피소드/일화, 발견/고안, 선형적인 발전, 역사적 실험의 4가지 영역으로 세분된다. 역할 차원은 기본적, 보충적, 탐구적의 3가지 영역으로 세분된다. 개발된 3차원 분석틀을 적용하여 과학 교과서의 지구과학사 자료들을 분석한 결과, 수업맥락 차원에서는 개념적 맥락의 과학사 자료가 모든 학년별 과학 교과서에서 가장 많았다. 역할 차원에서는 기본적 역할이 압도적으로 많았으며, 탐구적 역할의 경우에는 매우 적었다. 제시유형 차원에서는 발견/고안과 선형적인 발전 유형이 대부분이었고, 에피소드/일화 유형의 자료는 주로 흥미 맥락과 연계되어 극히 일부만 사용되고 있었다. 3차원 각 영역들을 48개의 조합으로 분석한 결과, '개념적 수업맥락-기본적 역할-발견/고안 유형'과 '개념적 수업맥락-기본적 역할-선형적 발전 유형' 2개 조합에 집중되었으며, 나머지 조합들의 빈도는 매우 낮았다. 전체적으로 3차원 분석틀 각 영역에 부합하는 과학사 자료가 과학 교과서에 다양하게 포함되지 못하고 일부 영역에만 집중되는 것으로 나타났으며, 이러한 연구 결과는 앞으로 다양한 수업맥락, 역할, 그리고 유형으로 과학사 자료들이 개발될 필요가 있음을 시사한다.

History of science (HOS, hereafter) has been considered as a useful tool for achieving a variety of objectives in science lesson. The purpose of this study was to develop three dimensional framework for effectively analyzing HOS content in science textbook. In addition, using this framework, we analyzed HOS content in science textbooks of the 7th curriculum by focusing on the history of Earth science. Developed framework consists of three dimensions; instruction context, role, and type. Each dimension has several sub-domains. The results of textbook analysis revealed that science textbook didn't include diverse HOS materials that are appropriate to three dimensions and its sub-domains of the framework. Based on the results, we proposed that three dimensional framework is an effective tool to develop materials for teaching and learning materials of HOS with multiple coordinations of various contexts and purposes.

The opinion, that the history of science should be introduced to science lesson, has been continuously emphasized by a group of people who supported the needs of science and scientific process, nature of science, and the interaction between science and society. When the importance of the integrated science education is emphasized, the history of science is suggested as an effective curriculum for it. To respond to this identified interest, we developed a lesson of the history of science by selecting the contents of the history of science as subject topics of the integrated science and by utilizing the findings of previous studies related to the history of science in science educations. To develop the history of science class as a subject of integrated science, we chose 'the age of the earth' as a unit. After the pilot test of the unit in secondary school students, the possibility of offering the lesson as a regular course was examined with analysis of the students' reactions showing its effectiveness.

The effects of education utilizing history of science on science achievement and attitudes of the ninth grade students were investigated according to their achievement level, along with the development of teaching and ;earning materials. A total of 144 ninth grade students were divided into the experiment and control group. Instructing students using history of science was performed in the experiment group, while conventional instruction was used in the control group. The scores of both pre-test and post-test were estimated by ANCOVA. Instructions applying history of science were more effective in increasing the students' science achievement and attitude than conventional instructions. In particular, the former enhanced the achievements of the upper-level students, more than it did for the middle and lower-level students. In addition, using history of science showed a better effect on higher and middle-level students, in improving their attitudes toward science, than it did for lower-level students. This study suggests that the instruction utilizing history of science should be designed based on the students' achievement level, and that various teaching and learning materials related to the instruction were helpful.

The objective of this study is to examine the cognitive process that undergoes a middle student’s conceptual change about the universe by the cognitive conflict, using science history materials as a teaching strategy. Four eighth graders were selected and classified by three cognitive level. Students were interviewed and conducted to an inquiry activities regarding their viewpoint about the universe after each class, and their conceptual change patterns were analysed from pre-test and post-test. This study showed that each student held dissimilar astronomical preconceptions and various misconceptions about celestial motion. Students at the formal operational stage and transitional stage experienced the conceptual change from geocentricism to heliocentricism by instructional model upon the science history materials. Student at the concrete operational stage had either unscientific conception, no conception, or could not have a conceptual change even when being presented with an environment that arouses cognitive conflict ($R^2$: Phase change of Venus and its Rise and set time). They ended up having a cognitive change from geocentricism to heliocentricism by solving another problem ($R^2$: Relation between visible diameter and position of Mars). After the instruction, a conceptual achievement progress was reported with a $10\%$ improvement. Therefore, the instruction model based upon science history was effective on student’s scientific conceptual change.
