  • In this study, we investigated the philosophical background and progress of the 2022 revised curriculum development in the high school earth science field. Research that was not covered in the research report includes the relevance of the transformative competency of OECD Education 2030, and that core ideas and achievement standards are organized around knowledge understanding, process functions, and value attitudes that constitute the learning compass needle. In addition, the composition of core ideas and Earth science electives in light of the understanding-centered curriculum, and IB type inquiry-based teaching and learning. Main research results include that the 2022 revised Earth science curriculum emphasized the student agency to foster the transformative competency and scientific literacy, and the curriculum document system in the field of earth science uses a learning compass needle. In addition, based on the understanding-centered curriculum, core ideas of Earth science were derived, and elective courses were organized to help students reach these core ideas. Also, IB-type inquiry-based teaching and learning was emphasized to foster student agency with knowledge construction competency. Based on the research results, slimming of the national and general level curriculum, the need to develop process-centered assessment methods for value and attitudes, the need for curriculum backward design, and ways to develop student agency through inquiry-based teaching and learning were suggested.

  • This study aims to analyze the aspect of inquiry activity for seven national science textbooks, which were recently authorized and developed for elementary schools. The study reviewed seven of the abovementioned textbooks, which were introduced to the authorized textbook system for 2022 in elementary schools. In-depth analysis was conducted on inquiry activities, which were frequently emphasized since the third curriculum. A chapter entitled "Stratum and Fossils" was selected to analyze the detailed types of inquiry activity using the framework. First, analysis was conducted on six types of inquiry activity. The result indicated that two out of seven inquiry activities different among the national and authorized textbooks. In other words, the two slightly differed from the inquiry activities presented in national textbooks. It was not reasonable that the introduction of the authorized textbook exerted an effect on the increase of autonomy and variety of teaching and learning activities compared with those of national textbooks. Second, science process skills, material, and inquiry process were established as standards for the detailed types of inquiry activity. The study demonstrated a slight difference among textbooks in terms of material and inquiry process, whereas the inquiry activities of the seven authorized textbooks were the same or similar. This finding indicated that students could experience seven types of inquiry activities. Moreover, the study examined inquiry activities related to essential learning contents in detail and found that there were more diverse than types of inquiry activities.

  • 본 논문의 목적은 집합론이 메타논리학에 필수불가결하다는 주장, 즉 필수불가결성 논제에 반대하는 것이다. 만일 집합론이 메타논리학에 필수불가결하다면, 집합론을 포함하게 되는 논리적 탐구는 논리학의 가장 근본적인 특성들인 주제중립성과 보편적 적용가능성을 결여하게 되기 때문이다. 논리학의 주제중립성은 논리학의 명제들이 개별 과학과 같은 특정한 지식 분야에 국한되지 않는다는 것을 말하며, 논리학의 보편적 적용가능성은 논리학의 명제들과 추론 규칙들이 모든 과학 분야들과 합리적 담론들에서 사용될 수 있다는 것을 말한다. 나아가 주제중립성과 보편적 적용가능성을 지니기 위해서는, 논리학을 기술하는 메타논리적 용어들과 개념들 역시 이러한 특성들을 지녀야만 한다. 하지만 필수불가결성 논제를 받아들이게 되면, 우리는 논리학이 적용되는 모든 분야에서 집합론의 용어들과 집합론적 개념들이 필수불가결하다는 것을 받아들여야만 한다. 그리고 이는 분명 불합리한 일이다. 필수불가결성 논제가 그럴듯하지 않다는 것을 보이기 위해서 나는 집합과 관련된 존재론적 문제를 살펴볼 것이다. 이러한 탐구는 집합이 어떤 식으로 이해되든지 간에 존재론적으로 보수적인 "논리적 존재자" 로 간주되기 어렵다는 것을 보여줄 것이다.

  • The purpose of this study was to develop 'Science History Based Chemist Inquiry Program' for the science-gifted in high school and investigated the application effects on the understanding toward the nature of science, scientific attitudes, and science career orientation. This study was conducted with one class of 17 scientifically gifted high school students, and the 'Science History Based Chemist Inquiry Program' was applied during 22 class hours. The results of this study were as follows: First, the science gifted students' understanding toward the nature of science showed a statistically significant improvement (approximate significance probability .005). Property of the scientific model, sub-domain of the nature of science, is significantly improved (approximate significance probability .029). This result show that 'Science History Based Chemist Inquiry Program' can improve the scientifically gifted high school students' perception about nature of science. Second, the scientifically gifted students' scientific attitude wasn't changed significantly. However, the openness and creativity in the sub-domains of the scientific attitude showed a statistically significant improvement (p<.05). Third, science career orientation of science-gifted did not show a statistically significant change. But the value of the level of awareness about the science career has been significantly improved (p<.05).

  • This study analyzes the verbal interaction patterns used in a social network activity analysis that appeared in a science inquiry activity of 31 small groups of science-gifted students consisting of 5 members each. The results of this study are as follows: The interaction patterns showed eight types. The most prevalent interaction pattern, type 1, is triangle-shaped, interacting with 3 members out of 5 without a central member. Type 2 is wye form, interacting with 4 members and with one alienated member. Type 3 is diamond-shaped, interacting with 4 members. Type 4 is ray form, interacting with 5 around a central member. Type 5 has an alienated member and interacts with 4 members around the central member. Type 6 is triangle-branched, 4 members linked to the central member. Type 7 is wye form linked all around the central member. Type 8 is wye form with a more complex link than type 7. These can be classified in two. One is the participation-type where the rest of the 4 members are linked to the central member. The other is the alienation-type where a member/members is/are alienated without a central member. The participation-type appeared in 9 groups (29%), type 4, type 6, type 7, and type 8. The alienation-type showed in 22 groups (71%), type 1, type 2, type 3, and type 5. On the basis of this study, we propose that the best number of members in a group is three. It helps prevent a free-riding effect or isolation of members. Also, we deem it more fruitful if there is a member playing a central role in a group.

  • Inquiry approach in teaching science has been widespread in Korea since the Third National Curriculum in 1970's. But the effect of the approach has never been evaluated systematically in Korea, so the science educators do not know if the inquiry approach really works and if any critical problems inhibit the effect of the approach. In this context, the NAEP of the Unied States and the APU of the United Kingdom were model programs for assessing the effect of the inquiry approach in teaching science. The purpose of this study is to develop an assessment system for evaluating the effect of inquiry teaching in elementary and secandary schools. For this purpose, an assessment framework and 240 test items were developed and tried with a sample of 8,906 students. The results say that the developed tests are reliable. The average Cronbach $\alpha$ reliability coefficient of the tests was 0.69. The discrimination index(point-biserial correlation coefficient) ranged from 0.39 to 0.54 with a mean of 0.49, which indiate they are excellent in discriminating students in terms of their inquiry achievement. The test items were also analyzed by "item response theory." The results also say that the items are successfully developed.

  • 지구과학은 실생활과 직접적으로 관련되거나 학생들이 친숙하게 생각하는 많은 개념들을 포함하고 있으며 이런 특성은 과학캠프나 자연탐사 활동에서 지구과학과 관련한 탐구주제가 학생들의 큰 호응을 얻는 사실을 설명할 수 있다. 하지만 정규 수업에서 이루어지는 지구과학 실험 수업은 교과서에 제시된 자료해석 위주의 실험이 많아 학생들의 흥미를 반감시키는 경우가 많으며 자료 측정과정에서 과학자가 느낄 수 있는 중요하고 귀중한 경험을 놓칠수 있다. 그런데 인터넷에서는 해양과 대기, 천문, 지질 각 분야에서 지속적으로 갱신되는 실시간 관측 자료를 제공해 주는 곳이 많으며 이 실시간 자료들을 고등학교의 지구과학 실험에 이용할 수 있도록 학습 프로그램을 개발하면 기존의 자료해석 실험이 가지는 한계를 극복하고 학생들의 지구과학에 대한 호응도를 높일 수 있으며 보다 다양한 탐구 능력을 향상 시킬 수 있다. 이러한 학습 프로그램의 특징은 탐구 중심 혹은 문제 해결 학습을 강조하는 현재의 교육 목표를 잘 반영할 수 있다. 본 연구의 목적은 인터넷에서 제공되는 지구과학 관련 실시간 자료들을 활용할 수 있는 고등학교 지구과학 학습 프로그램을 개발하고 이를 지원할 수 있는 홈페이지를 구축한 후 실제로 수업에 적용하여 교육적 효과를 확인하는 것이다. 연구 결과 실시간 자료를 이용하는 고등학교 학생들을 위한 지구과학 학습 프로그램을 12개의 주제에 대해서 완성했다. 먼저 지구과학실험 시간에 적용할 수 있는 2차시 분량의 학습 프로그램 6주제를 개발했는데 개발 주제는 '지진이 일어나고 있는 곳은 어디인가?', '진앙으로 판의 경계를 결정하기', '진앙의 위치를 찾아라', '암영대를 찾아라', '태양의 자전 주기를 측정하기', '태양활동' 이다. 각 주제별로 수업소개, 학습목표, 과정, 학습자료(학생 활동지, 기타 자료, 수업 내용과 관련한 실시간 자료 제공 사이트 목록), 평가 자료를 만들었다. 학생들의 활동 내용은 <지진이 일어나고 있는 곳은 어디인가?>의 주제를 예로 들면 학생들이 실시간으로 전 세계의 지진활동을 모니터하는 사이트에 접속하여 최근에 지진이 어디에서 일어났는지 알아보고 지난 30일 동안에 일어났던 규모 4 이상의 지진 자료를 다운 받아 세계 지도에 점으로 표시한다. 이 때 학생들은 손으로 진앙의 위치를 지도에 그리는 대신 엑셀의 그래프 기능을 이용하여 지도에 진앙의 위치를 나타내게 한다. 또 개인 과제 연구에 적용할 수 있는 학습 프로그램을 5가지 개발하여 학생들이 특정한 주제에 대하여 탐구 과제를 수행할 수 있게 했는데 개발된 주제는 '태양 활동으로 오로라 예측하기', '국제 우주 정거장을 찾아내자', '한반도 부근의 해양 기상과 해수의 물리적 상호 관계', '일기도 분석을 통한 태풍의 진로 예측', '우리 나라 조석 예측' 이다. 마지막으로 사이버 학습을 통해서 수업 시간의 제약 없이 과제 형태로 처치 가능한 학습 프로그램 개발 했는데 그 주제는 '태풍이 저위도에서 북상하는 이유?'이다. 개발된 프로그램 중 2차시 학습 프로그램은 과학고 중학생 영재반에게, 개인 탐구 과제는 과학고 1학년 학생들에게, 사이버 수업 형태는 과학고 2학년 학생에게 적용시켰다. 실시간 자료 활용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타 자료를 데이터베이스화했으며 이를 통해 학생들이 원하는 실시간 자료를 검색하여 찾을 수 있고 홈페이지를 방분했을 때 이해하기 어려운 그래프나 각 홈페이지가 제공하는 자료들에 대한 처리 방법을 도움말로 제공받을 수 있게 했다. 실시간 자료들을 이용한 학습은 학생들의 학습 의욕과 탐구 능력을 향상시켰으며 컴퓨터 활용 능력과 외국어 자료 활용 능력을 향상 시키는데도 도움을 주었다.

  • The effects of learning using Information Communication Technology(ICT) on the students' scientific inquiry ability and science-related affective characteristics were analyzed in Earth History and Crust Movement units of science textbook for eighth graders. For this study, two classes of middle school second students in Chung-nam were selected and taught for six week under different teaching methods. One class is the test class taught with ICT applied teaching materials and the other class is the control class instructed by a conventional method. One week before the experiment, both classes were given tests on scientific inquiry ability and science-related affective characteristics, and they were tested again after the experiment. The results of scientific inquiry test showed statistically meaningful differences in the experimental class and the control class. The experimental class showed statistically meaningful difference in scientific inquiry test. Science-related affective characteristics test showed no statistically meaningful difference in the experimental class. Among three scientific science-related affective characteristics, especially the one fields of interests showed statistically meaningful differences which suggest that learning using ICT has a positive effect on the expanding of students' science-related affective characteristics.

  • This study was to analyze the inquiry characteristics of preservice teachers as they classify trilobites. For the study, 70 preservice teachers attending teacher training university participated. The classification tasks used in the study were 9 photos of trilobite fossils. The preservice teachers' inquiry activity was to classify the evolutionary processes of trilobites after observing trilobite fossils by group and then to construct a phylogenetic tree. The results of the study are as follows. First, preservice teachers observed the external features of the trilobites and constructed systematic classification results based on their observed contents. Second, preservice teachers classified trilobites using various classification criteria. Third, the phylogenetic tree of preservice teachers and the phylogenetic tree of scientists were very similar. The preservice teachers constructed a sphylogenetic tree based on the observation and inference of the change from a simple form to a complex form, which is a general evolution process of the trilobite fossil claimed by scientists. These results suggest that group-based inquiry activities with sufficient time are very effective and that the experience of inquiry activities is very important for preservice teachers.
