The Effects of Science Lessons Applying STEAM Education Program on the Creativity and Interest Levels of Elementary Students

Abstract: According to trends in scientific technical competition, many countries around the world are interested in and focused on the STEAM integrated education. By observing the fact that the goal of our country`s science education is to cultivate creative workers who have scientific knowledge, the need for STEAM integrated education cannot be denied. Therefore, the purpose of this study was to develop the STEAM integrated program focused on themes that considered activities and interest in the grade 6 science subject in order to identify its influence on the creativity and interest levels of elementary students. The STEAM integrated education program in this study was developed so that it can be applied as a unit review or reinforcement activities in the closing activities per unit in grade 6. The focus was placed on heightening students` creativity and interest in science subject learning through a program focused on activities per theme. As a result of applying the developed STEAM integrated program in prior and post conditions on 3 elementary school`s students in J Province, it was discovered that significant improvement was found in the creativity and scientific interest of elementary students in the experimental group, compared to the control group. Therefore, continuous and systematic development of the STEAM integrated education program is required, and moreover, it must be developed for all elementary grade levels and efforts should be put into actively applying the program in the field of education.

The Introduction of Design Thinking to Science Education and Exploration of Its Characterizations as a Method for Group Creativity Education

Abstract: A R T I C L E I N F O A B S T R A C T Article history: Received 3 January 2014 Received in revised form 18 February 2014 27 March 2014 1 April 2014 Accepted 3 April 2014 Group creativity has recently been heightened as a core ​competence in the 21st century. Therefore, there is a need for introduction of concepts on design thinking emphasizing the collaboration and empathy to science education as an effective method for fostering group creativity. Understanding design thinking for effective introduction should be preceded, so we explore the characterizations of design thinking through the generic model overlay method, focus group interview, and critical incident technique analysis. The results reveal 4 cluster units of competency and 15 core competencies. The collaboration cluster consists of 5 competencies and they are as follows: organization of the team, communication, self-control, persuasiveness, and initiative competency. The integrative thinking cluster consists of 3 competencies and they are as follows: analytical, strategic, and intuitive thinking competency. The human-centeredness cluster consists of 3 competencies and they are as follows: user-orientation, relationship building, and interpersonal understanding competency. The multidisciplinary cluster consists of 4 competencies and they are as follows: achievement orientation, information seeking, curiosity, and flexibility competency. Findings are expected to provide the basic data for developing programs and establishing strategies in order to foster group creativity as well as introducing design thinking to science education effectively.

Designing Collective Intelligence-based Instructional Models for Teaching Socioscientific Issues

Abstract: 본 연구에서는 과학관련 사회 · 윤리적 쟁점(SSI)과 집단지성과의 연관성을 고려하여, 집단지성 촉진 전략을 활용한 SSI 수업모형(CI기반 SSI 수업모형)을 현장 과학교사들과 협력적으로 개발하였다. 그리고, 수업모형 개발과정에서 참여 교사들이 SSI 수업에서 집단지성의 효과에 대해 어떻게 인식하는지를 살펴보고자 하였다. 본 연구에서 개발된 CI기반 SSI 수업모형은 SSI 수업에서 교사들이 추구하는 목적에 따라 크게 3개의 유형(발산적 모형, 탐색적 모형, 의사결정 모형)으로 나뉘며, 각 유형 당 2개씩 총 6개가 개발되었다. 첫째, 발산적 모형은 학생들이 주어진 SSI에 대한 의견이나 해결방안을 다양하게 발산해 보도록 하는데 초점을 둔 수업모형으로, 아이디어 생성 수업모형과 미래 상황 예측 수업모형이 해당된다. 둘째, 탐색적 모형은 문제를 둘러싸고 있는 다양한 입장들에 대해 탐색하여 SSI의 복잡성을 이해하는데 초점을 둔 수업모형으로, 쟁점 탐색 수업모형과 실제 사례 탐색 수업모형이 이 유형에 속한다. 셋째, 의사결정 모형은 주어진 SSI에 대해 다양한 입장을 이해하고 가장 합리적으로 집단의 의사결정을 하도록 의견을 수렴하고 조정하는데 초점을 둔 수업모형으로, 집단적 합의 수업모형과 대안 결정 수업모형이 해당된다. 참여교사들은 각 수업모형을 적용해본 결과 SSI 수업에서 집단지성의 원리를 강조한 것이 학생들의 참여도와 협력, 토론과 근거의 질을 높이는 데 기여했다고 보았다. 이를 위해서는 SSI 수업 도입 부분에서 문제해결을 위해 공유된 가치를 형성하는 과정, 개별적으로 자료를 수집할 수 있는 시간을 충분히 갖고 난 후 공유하는 과정, 개인적으로 자료를 수집하여 정리하고 공유할 수 있는 공간의 마련이 중요하다고 응답하였다.

Study on Korean Science Teachers' Perception in Accordance with the Trends of Core Competencies in Science Education Worldwide

Abstract: 이 연구의 목적은 영국, 호주, 뉴질랜드, 캐나다 온타리오주, 싱가포르 및 우리나라의 과학교과 핵심역량에 대한 동향을 조사하여 과학교육을 통해 기를 수 있는 핵심역량이 무엇인가을 알아보는 것이었다. 또한, 현장 과학교사들이 핵심역량 기반의 과학수업에 대해 어떻게 인식하고 있는지를 탐색하고, 특히 최근 핵심역량 기반의 과학교육과정을 접한 경기도 지역 교사들이 어떻게 인식하고 있는지를 알아보는 것이었다. 외국의 역량 기반 과학과 교육과정을 탐색하기 위해 각종 문헌연구를 실시하였으며, 현장 과학교사들의 인식 조사를 위해, 135명의 초·중·고등학교 교사들에게 설문을 실시하였다. 외국의 역량 기반 과학과 교육과정 탐색 결과, 각 국가들의 공통적인 특징으로 ‘범교과 역량과의 연계’, ‘과학 내용과 과학 활동의 결합’, ‘의사소통 능력 중시’, ‘역량별 성취 수준 제시’ 등이 나타났다. 또한, 각국에서 강조하는 과학과 핵심역량으로는, ‘비판적 사고력’, ‘창의적 사고력’, ‘문제해결력’, ‘탐구능력’, ‘의사소통능력’, ‘문화적 이해력’, ‘학문간 통합능력’, ‘적용능력’, ‘개인적 역량과 사회적 역량’이 있었다. 현장 과학 교사들은 현재 핵심역량에 대한 인지정도 및 과학수업에서의 실행 정도는 보통으로 생각하고 있었으나, 가르쳐야 한다는 움직임과 가르칠 의사에는 긍정적인 인식을 보임으로써, 필요성에 대해서는 공감하고 있었다. 중요한 핵심역량으로는, 초·중·고 세 학교급 모두에서 ‘창의적 사고력’, ‘문제 해결력’, ‘탐구 능력’을 꼽았으며, 교육 요구도가 가장 높은 역량은 ‘창의적 사고력’이었다. 경기도 지역의 교사들이 다른 일반지역의 교사들보다 핵심역량에 대한 인지정도가 높은 것으로 나타났으며, 핵심역량 기반의 과학 수업이 과학적 태도와 의사소통 능력 형성에 큰 도움이 된다고 보았다. 그러나 수업 운영 방법에 익숙하지 않은 점, 많은 수업 준비시간 등을 어려운 점으로 꼽았다.

Trends in Research Studies on Scientific Argument and Writing in Korea

Abstract: Ewha Womans UniversityA R T I C L E I N F O A B S T R A C TArticle history:Received 14 January 2014Received in revised form22 January 20143 March 20149 April 2014Accepted 23 April 2014The purpose of this study is to investigate trends in research studies on scientific argument and writing in Korea. 118 research studies published from 2004 to 2013 have been collected and analyzed. Many of the research studies focused on developing teaching strategies, analyzing contents of scientific argument and writing, and effects on student learning. More than half of the studies were conducted with elementary and middle school students while studies with pre-service, in-service teachers or high school students were relatively rare. Most research studies were conducted within regular school hour context and participants were given relevant information/education prior to argument and writing activities. Many research have analyzed student growth in scientific attitudes and we would suggest that further studies should investigate student growth in scientific concepts, scientific inquiry, and critical thinking. The structure and process of argument or the content and form of writing have been analyzed. The quality of argument and scientific concepts embedded in argument and writing should be investigated more in future researches.Key words:argument, science writing, research trends

Development and Validation of a Learning Progression for Astronomical Systems Using Ordered Multiple-Choice Items

Abstract: This study sought to investigate learning progressions for astronomical systems which synthesized the motion and structure of Earth, Earth-Moon system, solar system, and the universe. For this purpose we developed ordered multiple-choice items, applied them to elementary and middle school students, and provided validity evidence based on the consequence of assessment for interpretation of learning progressions. The study was conducted according to construct modeling approach. The results showed that the OMCs were appropriate for investigating learning progressions on astronomical systems, i.e., based on item fit analysis, students` responses to items were consistent with the measurement of Rasch model. Wright map analysis also represented that the assessment items were very effective in examining students` hypothetical pathways of development of understanding astronomical systems. At the lower anchor of the learning progression, while students perceived the change of location and direction of celestial bodies with only two-dimensional earth-based view, they failed to connect the locations of celestial bodies with Earth-Moon system model, and they could recognized simple patterns of planets in the solar system and milky way. At the intermediate levels, students interpreted celestial motion using the model of Earth rotation and revolution, Earth-Moon system, and solar system with space-based view, and they could also relate the elements of astronomical structures with the models. At the upper anchor, students showed the perspective change between space-based view and earth-based view, and applied it to celestial motion of astronomical systems, and they understood the correlation among sub-elements of astronomical systems and applied it to the system model.

Analysis of Relationships of Scientific Communication Skills, Science Process Skills, Logical Thinking Skills, and Academic Achievement Level of Elementary School Students

Abstract: 이 연구는 초등학생들의 과학적 의사소통능력, 과학 탐구능력, 논리적 사고력이 학업성취도 수준에 미치는 영향을 분석하여, 과학적 소양함양을 위한 교육에 시사점을 얻고자 하였다. 초등학교 6학년 학생 64명을 대상으로 과학적 의사소통능력 검사(SCST), 과학 탐구능력검사(TSPS), 논리적 사고력 검사(GALT)를 실시하였으며, 과학교과 지필 평가와 과학교과 서술형 평가, 전체교과의 학업성취도 평가를 통해 자료를 수집하였다. 이러한 자료를 바탕으로 과학 탐구능력과 논리적 사고력, 과학적 의사소통능력의 상호간의 상관관계를 분석하고, 각각의 능력의 하위 요소별로 학업 성취도와의 영향을 분석하였다. 그리고 과학 탐구능력과 논리적 사고력이 영향을 주고 있는 과학적의사소통능력이 학업성취수준에 직접적인 영향을 미친다는 가정아래세 가지 유형의 성취도평가와의 상관관계를 구조적인 모형으로 분석하였다. 연구 결과 과학적 의사소통능력과 과학 탐구능력, 논리적 사고력은 서로 높은 상관관계를 가지고 있었다. 그리고 이 세 능력은 학습자의 과학교과 지필, 과학교과 서술형, 전체교과 학업 성취도 수준와도 유의미한 상관관계를 가졌으며, 하위 요소별로 그 상관정도는 조금씩다르게 나타났다. 마지막으로 과학 탐구능력과 논리적 사고력이 과학적 의사소통능력에 영향을 주고 과학적 의사소통능력이 학습자의 학업성취도 수준에 직접적인 영향을 끼친다는 모형을 설정하여 분석한 결과, 과학적 의사소통능력이 전체 교과에 대한 학업 성취도 수준에 가장 크게 영향을 주고 있었다.

The Characteristics of Lesson Planning of Pre-service Secondary Science Teachers

Abstract: A R T I C L E I N F O A B S T R A C T Article history: Received 5 March 2014 Received in revised form 31 March 2014 17 April 2014 Accepted 18 April 2014 In this study, we investigated the characteristics of lesson planning of pre-service secondary science teachers and the factors which influenced in their lesson planning. Thirteen pre-service secondary science teachers at a college of education in Seoul participated in this study. Teaching-learning materials such as lesson plans and handouts, and lesson planning journals written by the pre-service teachers were collected. Semi-structured interviews were also conducted to obtain information about their lesson planning activities. The analyses of the results revealed that most of the pre-service teachers did not systematically consider the national science curriculum and focused on planning one lesson only. Instructional objectives were not only considered as minor element in lesson planning, but also limited to cognitive domain. Devising teaching-learning strategies was found to be the starting point of the lesson planning. They accommodated constructivistic teaching-learning theory presented in their method courses through reflective evaluation of the experiences of learning in their secondary schools. The experiment activities that were presented in the textbooks were used themselves when they planned experiments as student activities, but other activities were planned depending on their personal experiences. Most pre-service teachers did not plan assessment because they could not recognize it as an element of lesson planning. These results may offer some implications in educating pre-service secondary science teachers on lesson planning.

과학적 글쓰기를 활용한 논의-기반 모델링 전략의 개발

Abstract: 이 연구는 과학교육에서 의사소통을 위해 글쓰기와 논의를 활용한 논의-기반 모델링 전략의 개발을 목적으로 하였다. 논의-기반 모델링 전략은 모델링의 목적인 의사소통을 위해 자신이 만든 모델을 논의와 글쓰기를 통해 과학적 언어를 사용하여 스스로 정리하거나 표현하고, 다른 사람의 의견을 듣고 교환하는 과정을 통해 모델을 평가하고 수정하는 일련의 과정을 의미한다. 이 전략은 과학교육에서 모델링에 어려움을 느끼는 학생과 교사를 지원하기 위한 것으로 다음 네 가지 요소의 발달에 초점을 맞추었다. 첫째 여러 문제 상황을 관찰하여 문제를 연관지어 인식하는 문제인식이다. 둘째는 과학적 설명을 위해 충분한 과학개념을 구조화하여 제시하는 과학개념 구조화이며, 셋째는 주장에 대해 적절한 표상을 증거로 제시하는 주장-증거 적절성이다. 마지막은 증거제시에서 다양한 표상의 사용과 이 표상들을 전환하고 통합하는 다중표상 지수이다. 이 네 가지 요소의 발달을 위해 세 가지 stage를 구성하였다. ‘인지 과정’은 다중표상에 대한 이해를 위한 것이고, ‘해석 과정’은 다중표상 활동을 통해 증거 제시의 중요성을 인식하는 것이며, ‘적용 과정’은 학생들이 논의-기반 모델링을 직접 접해보는 것이다. 이 적용 과정에서는 질문 또는 문제 만들기-실험 설계 및 수행하기-관찰 통한 조사하기-자료의 분석 및 해석하기-임시 모델 설계하기-논의하기-되돌아보기-모델 평가하기-모델 수정하기의 아홉 개의 단계로 이루어진다. 논의-기반 모델링 전략은 학생들이 자신이 설계한 임시 모델을 다른 사람과 공유하기 위해 증거를 바탕으로 발표하고 반박하는 논의과정을 통해 증거 제시의 필요성을 인식할 수 있다. 논의과정 후 학생들은 주장과 증거를 다중표상으로 나타내는 것에 대해 되돌아보는 과정을 거치면서 주장-증거 적절성을 높이게 된다. 또한 모델을 평가하기 위한 기준을 만들고, 이를 바탕으로 자신의 모둠이나 다른 모둠의 모델을 평가하고 그 결과를 피드백 받으면서 수정하게 된다. 이러한 일련의 과정을 거치면서 관찰한 자연세계의 현상에 대한 자신의 설명체계를 만듦으로써 과학적 지식을 형성할 수 있는 기회를 제공받을 수 있다.

A Study on Elementary Students' Perceptions of Science, Engineering, and Technology and on the Images of Scientists, Engineers, and Technicians

Abstract: The purpose of this study was to investigate elementary school students’ perceptions about science, engineering and technology and their images of scientists, engineers, and technicians. In order to investigate students' images of scientists, engineers, technicians and student's perception of science, engineering, and technology, we used the tools “Draw a scientist at work, Draw an engineer at work, and Draw a technician at work.” We have revised the tool DAST (Draw a scientist test), which was used in Fralick et al.’s study (2009). Subjects were 209 6th grade students sampled from an elementary school in G-city in Korea. According to the results of this study, the students' representative image of a scientist was similar to stereotypical scientist image in previous studies, but the students perceived science as a field of research with various professionals. The students' representative image of an engineer was a man with short hair, no beard or mustache, wearing ordinary clothes but no glasses. The engineer was designing or constructing a ship, a robot, a computer, and an airplane. The students' representative image of a technician was a man with short hair, wearing protective goggles and a mask for welding. The technician was fixing a car, a robot, a rocket, etc. and working with wrenches, hammers, screw drivers, welding machines, etc. Many students didn't perceive engineering and technology as fields of research. Also, many students didn't variously perceive engineering and technology as fields and ways of study.

Theoretical Investigation on Implications of 'Community of Inquiry' for Science Education: Toward 'Community of Inquiry in Science Classroom'

Abstract: Received 28 April 2014Received in revised form21 May 201428 May 2014Accepted 28 May 2014The purpose of this study is to investigate theoretically the meaning and features of the Community of Inquiry (CoI) based on the views of Peirce and Dewey, and to explore the implications of CoI in science education. The meaning and features of CoI are: (a) inquiry in CoI is initiated with faithful doubt; (b) inquiry in CoI finishes with faithful belief; (c) inquiry in CoI attempts to find out the best explanation and solution regarding the practical effects of objects; (d) as an ideal community, CoI is required to be one that inquires continuously without definite limits; (e) as an actual community, CoI requires its members’ open communication to find the best explanation and solution. Based on these features of CoI, the Community of Inquiry in Science Classroom (CoI-SC), “the classroom community for the purpose of transforming the state of faithful doubt into the state of faithful belief, in relation to natural phenomena or objects, and where the members share objectives as participants continuously attempt to find out the best explanation and solution by open communication, considering fallibility and the practical effects of objects”, was suggested. The condition for implementation of the CoI-SC, “‘interest’, ‘openness’, ‘rigor’, ‘fallibilism’, ‘participation’, ‘inquiry without definite limits’”, were also suggested. Finally, several suggestions for the science curriculum were given.

The Impact of the Argument-based Modeling Strategy using Scientific Writing implemented in Middle School Science

Abstract: Received 23 July 2014Received in revised form9 August 201421 August 2014Accepted 25 August 2014The purpose of this study is to investigate the impact of argument-based modeling strategy using scientific writing on student's modeling ability. For this study, 66 students (three classes) from the 7th grade were selected and of these, 43 students (two classes) were assigned to two experimental groups while the other 23 students (one class) were assigned to comparative group. In the experimental groups, one group (22 students) was Argument-based multimodal Representation and Modeling (AbRM), and the other group (21 students) was Argument-based Modeling (AbM). Modeling ability consisted of identifying the problem, structuring of scientific concepts, adequacy of claim and evidence and index of multimodal representation. As for the modeling ability, AbRM group scored significantly higher than the other groups, AbM group was significantly higher than comparative group. The four sub-elements of modeling ability in the AbRM group was significantly higher than the other groups statistically and AbM group scored significantly higher than comparative group. From these results, the argument-based modeling strategy using scientific writing was effective on students' modeling ability. Students organized or expressed the model and evaluated or modified it through the process of argument-based modeling using scientific writing and the exchange of opinions with others by scientific language as argument and writing.

An Analysis of Structural Relationship Among the Attitude Toward Science, Science Motivation, Self-Regulated Learning Strategy, and Science Achievement in Middle School Students

Abstract: Received 31 July 2014Received in revised form12 August 201420 August 2014Accepted 21 August 2014The purpose of this study is to investigate the structural relationships among the attitude toward science and science motivation such as affective characteristics, and self-regulated learning strategy such as cognitive factor of science achievement. 853 middle school students residing in Seoul completed questionnaires about attitude toward science, science motivation, and self-regulated learning strategy. The sample variance-covariance matrix was analysed using AMOS 20.0, and a maximum likelihood minimization function. The results are as follows: First, attitude toward science, science motivation and self-regulated learning strategy of middle school students were all found to have a significant direct effect on science achievement. Second, attitude toward science and science motivation in middle school students has a direct effect on the self-regulated learning strategy. Third, attitude toward science in middle school students has a substantial indirect effect on science achievement mediated by their self-regulated learning strategy. Forth, science motivation in middle school students has indirect effect on science achievement mediated by their self-regulated learning strategy. Therefore, in order to improve science achievement among middle school students, teachers should consider synthetically the affective characteristics such as attitude toward science and science motivation, and cognitive factor such as self-regulated learning strategy.

The Effects of Formative Assessment Using Mobile Applications on Interest and Self-Directedness in Science Instruction

Abstract: Received 7 April 2014Received in revised form4 May 201416 May 2014Accepted 19 May 2014This study investigates the effects of formative assessment utilizing mobile applications on interest and self-directedness in science instruction. The study subjects are two 6th grade classes from H elementary school located in Incheon, and the experimental group and the comparative group are composed of 21 students, respectively. The students from the experimental group have been taught with mobile devices while the comparative group has been taught in methods consistent with the current teaching standards. For the sake of research, the results of the method applied to the mobile device focus group have been edited using Google Drive Forms, entered as QR codes and stored in order for them to later be utilized for teaching and learning process. In the process, the teacher has provided the students with feedback based on their answers. The students of comparative group are to solve the same formative assessment in paper. As a result, the teacher of the mobile device focus group has been able to go through twenty-nine questions on formative assessment in the teaching and learning process, confirm the correct answers five times and provide feedback twenty-five times for additional explanation. In the inquiry about interest, the mobile device group scored 4.64 points and the standard one scored just 1.99 points (

핵심역량과 융합교육에 초점을 둔 과학과 교육과정 개선방향 연구

Abstract: 미래 사회의 변화는 미래 교육의 변화를 요청하며, 이러한 미래 교육의 변화 요청을 과학과 교육과정에서도 적극적으로 반영해 나갈 필요가 있다. 이를 위해 본 연구에서는 현재 교육과정인 2009개정 과학과 교육과정에 대한 실태를 진단하고, 미래교육의 변화 방향에 비추어 개선방안을 제시하고자 한다. 본 연구는 초·중·고 과학교사 447명의 설문조사와 12명의 전문가 심층면담을 통해 과학과 교육과정의 주요 쟁점 및 개선 방안을 탐색하였다. 과학과 선택과목 구성, 일반선택과목인 융합형 ‘과학’, 과학 과목 집중이수제, 진로집중과정, 과학과 선택과목의 이수단위 증감, 대학 입시에서 과학과 선택과목 간 형평성 등으로 구분하여 2009개정 과학과 교육과정의 문제점을 살펴보았다. 이어서 현장교사들과 전문가들이 제안한 과학과 교육과정 개정방향들 중 핵심역량과 융합교육에 초점을 두고 과학과 교육과정을 구상하는 방안을 탐색하였다. 그 결과 과학과의 핵심역량은 기존 교육과정에서 강조한 문제해결력, 의사소통 능력뿐만 아니라 기초학습능력과 자아정체성, 도덕적 역량 등이 추가되어야 함을 알 수 있었다. 융합교육은 다른 교과와의 융합 이전에 과학과 내부 과목 간 융합이 먼저 이뤄져야 하며, 과학 과목을 중심으로 한 STEM 형태의 융합이 바람직함을 알았다. 이러한 결과를 실천하기 위해서는 과학과 교육과정 연구·개발을 전담할 교육과정 개발센터의 구축이 필요하다.

Analysis of Science Educational Contents of Singapore, Canada and US Focused on the Integrated Concepts

Abstract: The feasibility of integrated concepts as a key element in designing integrated science curriculum has been investigated by analysing science contents included in performance expectations stated at different grades. The science curriculum of Singapore and the state of Ontario in Canada, and next generation of science standard (NGSS) were selected. Each of them presents theme, fundamental concepts, and crosscutting concepts, which has the characteristics of integrated concepts proposed in the study. Analysis showed that theme, fundamental concepts, and crosscutting concepts were influenced by the characteristics of each curriculum. In addition, science contents related to integrated concepts at different grades varied with the nature of integrated concepts. Based on results, some suggestions were made. First, the total number of integrated concepts should be considered for designing integrated curriculum. Second, the nature of integrated concepts and science contents associated with the integrated concepts should be considered. The integrated concepts should be vast and deep enough in the meaning to contain various content knowledge of different science domains. Third, it should be considered that how the integrated concepts have to be presented at different grades.

Using a Learning Progression to Characterize Korean Secondary Students' Knowledge and Submicroscopic Representations of the Particle Nature of Matter

Abstract: Learning Progressions(학습진행과정, 이하 LP)은 "과학의 핵심 아이디어(core idea) 혹은 과학 활동(scientific practices) 이해 과정을 상대적으로 단순한 체계에서 전문가의 지식체계로 논리적이고, 순차적인 단계로 정교하게 설명한 틀"로서, 한 교과 내 및 다른 과학영역들(물리, 지구과학, 생물, 화학)과 연결하여 연계적 교육과정을 구성하는 이론적 기반을 제공한다. 학습은 개개인의 선지식, 선경험, 교과교육과정, 교육과정 등의 여러 요소에 영향을 받는 복잡한 이해 과정으로, LP 단계를 모든 학생들이 동일하게 이동하지 않는다. 학생과 학습환경의 특성에 따른 이동 가능한 학습경로의 서술을 위해서는 다양한 학생데이터의 수집과 분석이 필요하다. 이러한 과정을 통해서 가설의 LP는 과학적으로 증명된 LP로 규명되며. 비로소 교과과정 개발의 틀(framework)로 역할을 할 수 있다. 본 연구는 미시간 대학 연구팀이 개발한 "물질의 본성(nature of matter)" 주요 개념에서, 하위개념인 "물질의 입자성(particule nature of matter)과 입자적 표상(submicroscophic representation)"의 LP와 관련 평가지를 우리나라 과학교육과정과 연계, 수정하여 개발하였다. 수정된 평가지와 LP는 124명의 중고등학생의 LP 경로 특성을 분석하는데 사용되었다. 학생들의 입자적 개념과 표상의 이해도, 개념과 표상 이해도 연관성을 중점으로 분석하여 관련 과학교육과정과 현장 수업의 문제점과 시사점을 도출하였다. 본 연구결과를 종합해 보면, 높은 레벨 문항의 정답을 고른 빈도수는 낮은 레벨 문항을 모두 정답으로 고른 경우에 높았으며 이는 학생들이 본 연구팀이 개발한 LP 경로로 이해과정을 정교화시킴을 알 수 있다. 하지만, 대부분의 학생들, 특히 고등학생들은 초등학교 수준의 거시적 물질의 본성 개념 LP 단계에 머물고 있으며, 중학교 수준인 미시적 표상 LP 단계에 있다. 입자적 개념과 표상 이해 실패의 주요 원인은 1) 과학적 모델의 본질, 2) 관련 선지식, 3) 미립자 표상의 이해부족으로 정리된다. 본 연구결과는 물질의 입자성과 관련된 개념, 과학활동(특히 모델링)을 증진시키고 개개인 특성에 맞는 맞춤형 학습환경 제공을 위한 학습, 교수, 평가자료 개발에 기여하는 바가 크다. 더 나아가 '물질의 본성'에 대한 LP연구와 과학적 소양 증진에 긍정적 역할을 할 것으로 기대한다. 【Learning progressions (LP), which describe how students may develop more sophisticated understanding over a defined period of time, can inform the design of instructional materials and assessment by providing a coherent, systematic measure of what can be regarded as "level appropriate." We developed LPs for the nature of matter for grades K-16. In order to empirically test Korean students, we revised one of the constructs and associated assessment items based on Korean National Science Standards. The assessment was administered to 124 Korean secondary students to measure their knowledge and submicroscopic representations, and to assign them to a level of learning progression for the particle nature of matter. We characterized the level of students' understanding and models of the particle nature of matter, and described how students interpret various representations of atoms and molecules to explain scientific phenomena. The results revealed that students have difficulties in understanding the relationship between the macroscopic and molecular levels of phenomena, even in high school science. Their difficulties may be attributed to a limited understanding of scientific modeling, a lack of understanding of the models used to represent the particle nature of matter, or limited understanding of the structure of matter. This work will inform assessment and curriculum materials development related to the fundamental relationship between macroscopic, observed phenomena and the behavior of atoms and molecules, and can be used to create individualized learning environments. In addition, the results contribute to scientific research literature on learning progressions on the nature of matter.】

A Case Study of Middle School Science Teachers’ Topic-Specific Pedagogical Content Knowledge on the Unit of Stars and Universe

Abstract: Pedagogical Content Knowledge (PCK) is intrinsically domain/topic-specific knowledge for teachers` expertise. On the basis of this idea about PCK, we investigated in-service science teachers` topic-specific PCK on the unit of stars and universe in terms of teachers` knowledge and practices. We observed four middle school science teachers` classes for eighth graders, and took the videos of the classes. The topics of the classes covered constellation, annual parallax and the distance of stars, and the expansion of the universe. We also examined the teachers` pedagogical thinking through video stimulated recall interviews. In addition, we developed a protocol to analyze the levels of participant teachers` PCK and the characteristics revealed in their classes on each topic. Results of the study showed that the participant teachers` level of PCK varied across the topics of classes and the sub-components of PCK. We also identified teaching orientations played key roles in shaping overall characteristics of their PCK. Moreover, astronomical thinking such as spatial thinking and system thinking, was not appropriately embedded as the specific practices into the astronomical concepts in their instructions.

과학교육의 태도와 흥미 연구에서 리커트 척도 활용의 유의점

Abstract: 일반적으로 연구자들은 관찰할 수 없는 심리적인 특성들을 연구할 때 주로 척도를 이용하여 수량화한다. 과학교육 연구에서도 척도를 활용하는 사례가 자주 나타난다. 특히, 정의적 영역의 평가에서는 학생들의 태도나 인식 등의 특성을 파악하고 평가하기 위하여 척도를 많이 사용한다. 그 중에서 사용이 간편한 리커트 척도를 많이 활용한다. 하지만 리커트 척도의 경우 활용 과정에서 여러 오류들이 발생하여 이를 절대시하는 것은 유의해야 한다. 이에 본 연구에서는 흥미와 태도 관련 과학교육 연구에서 리커트 척도의 활용에 따른 중심화 경향을 살펴보고 연구 대상 및 연구 내용에 따라 그 경향성이 어떠한지 분석하였다. 연구결과 연구 대상에 따라서는 대상 학교급 즉, 연령이 높아질수록 중심화 경향이 더 크게 나타났으며, 영재학생보다 일반학생의 경우 중심화 경향이 더 크게 나타났다. 연구 내용에서는 자기노출이 비교적 큰 영역에서 중심화 경향 더 나타났다. 그러므로 과학교육 연구에서도 리커트 척도를 활용할 때 중심화 경향의 오류가 발생하는 것을 알 수 있었다. 따라서 과학교육 연구에 리커트 척도를 활용할 때는 사회문화적 환경과 연구 대상 및 연구 내용의 특성을 고려할 필요가 있다. 또한 리커트 척도를 개선하여 적용해야 하며 나아가 조사 결과의 수치에만 의존하여 해석하는 것을 피해야 할 것이다.

The Development and Validation of Instrument for Measuring High School Students’ Attitude Toward Convergence

Abstract: A R T I C L E I N F O A B S T R A C T Article history: Received 8 January 2014 Received in revised form 18 February 2014 26 February 2014 Accepted 25 March 2014 This study aims to develop and validate an instrument to measure students’ attitude toward convergence. To do so, we have defined five constructs (i.e. knowledge about convergence, personal relevance, social relevance, interest and self-efficacy) of ‘attitude toward convergence’ based on literature review, developed items, and collected data from 233 11th grade science track students. The validity of these items have been evaluated by Messick’s framework (1995) (i.e. content, substantive, structural aspects of validity), experts’ review, Rasch analysis, and confirmatory factor analysis using structural equation modeling. Our results have confirmed the five constructs and 23 selected items have met the benchmark of item validity. Moreover, the theoretical model illustrating that the high level of attitude toward convergence increases the level of science motivation has also been supported by the data. The items developed in this study will be used to measure students’ attitude toward convergence and to estimate the effect of learning program for convergence science.

What Do Scientists Think about the Nature of Science? - Exploring Views of the Nature of Science of Korean Scientists Related with Life Science Area

Abstract: * 교신저자 : 이영희 (yhlee2014@dankook.ac.kr) http://dx.doi.org/10.14697/jkase.2014.34.7.0677 I. 서론 과학의 본성(Nature of Science)에 대한 연구와 이해는 지난 수십 년 동안 과학 교육학계의 가장 중요한 연구 주제중의 하나가 되어 왔다. 미국을 비롯한 많은 외국에서도 자국의 과학교육의 핵심적인 목표로 과학의 본성에 대한 이해를 손꼽았으며 그에 따라 중요한 국가 적 차원의 지침서 등에서 과학의 본성을 강조하여 왔다(AAAS, 1990, 1993; Ackerson, Buzzelli, & Donnelly, 2010; McDonald, 2010; NRC, 1996, 2012; NSTA, 1982). 우리나라에서도 시대의 변화에 따라 요구 되는 인간상의 변화와 국제 정보화 시대에 발맞춘 과학적 소양인 양성 이라는 교육목표에 따라 과학적 소양의 핵심 요소인 과학의 본성의 중요성이 널리 인식되고 있다(Ministry of Education, Science and Technology [MEST], 2012). 이와 같이 과학의 본성에 대한 과학교육 연구자들의 관심과 요구에 따라 다양한 주제와 방식으로 과학의 본성 에 대한 연구가 이루어지고 있다. 특히 과학의 본성이 과학의 인식론적 인 측면이라는 추상적이고 다소 복잡한 주제이기 때문에 그동안 많은 과학교육 연구자들은 교사들과 학생들에게 효과적인 과학의 본성을 지도하기 위하여 어느 수준의, 어떤 내용들을 교수학습 해야 할지를 연구해 왔으며 마침내 현재는 일정한 수준으로 합의된 구체적인 과학 의 본성 내용들을 정립하였다(AAAS, 1990, 1993; Ackerson, Morrison, & McDuffie, 2006; Bartholomew, Osborne, & Ratcliffe, 2004; Lederman et al., 2002; McComas, 2005; NRC, 1996; NSTA, 2000). 다음 Table 1은 미국 과학교사 협회(National Science Teacher Association: NSTA) 및 다른 선행 연구들에서 제시한 과학의 본성 내용들을 보여주고 있는데 여기에 제시된 과학의 본성 내용들은 일반 적으로 많은 과학교육자들이 동의하고 있는 내용들이라고 할 수 있다. 과학의 본성에 대한 정의와 내용은 과학교육자들 사이에서도 쉽게 의 견의 일치를 보기 어려운 영역인 것은 사실이나 과학의 본성이 과학의 인식론적인 측면, 아는 방법으로의 과학에 대한 개념, 그리고 과학적 지식 이면에 숨겨진 가치와 신념이라는 것에는 많은 연구자들이 동의 하고 있다(Abd-El-Khalick, 2005; Lederman, 1992). 또한 과학의 본성 이 과학적 지식 영역뿐 아니라 탐구 과정, 과학 지식의 본질, 과학자들 의 신념이나 태도, 그리고 과학과 사회/문화의 상호작용을 포함하고 있다는 것을 알 수 있다(Bayir, Cakici, & Ertas, 2014). 그 동안 국내외에서 진행된 과학의 본성 관련 주요 연구로는 과학의 구체적 본성 내용을 제시하는 연구들(Ackerson, Morrison, & McDuffie, 2006; Lederman et al., 2002; McComas, 2005; Bartholomew, Osborne, & Ratcliffe, 2004; Osborne et al., 2003; Lee, 2013a), 교사와 학생들의 Journal of the Korean Association for Science Education Journal homepage: www.koreascience.org

한국과 미국 초등학교 교과서에 나타난 과학의 본성 비교 분석

Abstract: The national reform document, Science for All Americans (AAAS, 1990), and the Next Generation Science Standards (NRC, 2012) emphasize the importance of the nature of science in guiding science educators in accurately portraying science to students. Therefore, it is important that textbook materials convey an accurate conception of the nature of science. This study employs content analysis to examine the content of textbooks in US and Korea elementary science textbooks with regard to the four aspects of the nature of science: (a) nature of scientific knowledge; (b) nature of scientific inquiry; (c) nature of scientific thinking; and (d) nature of interactions among science, technology, and society (Chiappetta, Fillman, & Sethna, 2004). Intercoder reliability was determined by calculating Cohen`s kappa (Cohen, 1960). Findings show that while US elementary science textbooks are not balanced in presenting the four aspects of the nature of science regardless of the publishing companies, the presentation of the nature of science in Korean elementary science textbooks have better balanced treatment of the four themes across the grade levels. On the other hand, both US and Korean elementary science textbooks are attempting to convey an idea of what science is by emphasizing scientific knowledge and investigation.

Implications of Science Education as Interdisciplinary Education through the Cases of Scientists and Artists in the Modern Era: Focus on the Relationship Between Science and the Arts

Abstract: Article history: Received 10 October 2014 Received in revised form 9 December 2014 Accepted 19 December 2014 The convergence and consilience in education (hereafter, interdisciplinary education) is receiving great attention from societies. This study aims to investigate the works of scientists and artists who have intended to combine science with the arts in the modern era, to take into account the socio-philosophical setbacks during the period, and to suggest pedagogical implications of science education as interdisciplinary education. The concept of interdisciplinary education stems from Plato’s thought, idea, as a comprehensive and invariant truth. The renaissance, full of enrichment about scientific achievement, was based on Neo-Platonism pursuing holistic-synthetic approach. During the time, scientists presented in this study tried to find comprehensive principles and borrow useful method from the arts. In such a context, scientists not only made use of the arts for expression of scientific knowledge, but also drew conclusion by analogical reasoning between science and the arts. Artists, as well, relied upon anatomy and optics especially, to elaborate linear perspective and even developed their own scientific knowledge through personal experience. Hence, contemporary science education should encourage students to hold a holistic viewpoint about science and the arts, articulate explicit goals and outcomes as interdisciplinary education, implement meta-disciplinary instruction about science and the arts, and develop assessment framework for collaborative learning. There may be good examples for inter-disciplinary education as listed: illustrating scientific ideas through the arts and vice versa, organizing collaborative works and evaluations criteria for them, and stressing problem solving on a daily basis.

Law, Theory, and Principle: Confusion in the Normative Meaning and Actual Usage

Abstract: Received 26 May 2014Received in revised form23 June 201419 August 2014Accepte 25 August 2014Educational Discourses on the nature of science(NOS) identify understanding of the role of scientific knowledge, especially the distinction between law and theory, as a crucial goal of instruction. However, the scientist community uses the terms such as law, theory, and principle without explicit definition so that the terms have no coherent meanings in their conventional language expression. The inconsistency between the norm and the reality could impose confusion on the teaching and learning. From the awareness of the problem, this study critically reviews the science education research papers and literatures on the philosophy of science which focus on the meaning of law, theory, or principle and the structure of scientific knowledge. From the examination of the science education researches, it is revealed that the disparity between the normative meanings of the law and theory by NOS researchers and actual usage of the terms is quite serious. From the review of the literatures of the philosophy of science, the necessity of the distintion of three categories: law, theory, and principle beyond the dichotomy between law and theory is brought up. By synthesizing the related literatures, we provide an outline of the characteristics of knowledges belonging to law, theory, and principle. Considering the conflict between the normative definition and the conventional language, it could be unnecessary to emphasize clear distinction on the terms as an instructional goal. Instead, the goal of instruction should focus on that there are three types of scientific knowledges of different functions and characteristics.

Analysis of Scientific Inquiry Elements in Middle School Science Textbooks, Teachers` Cognition, and an Experiment Case

Abstract: Received 25 February 2014Received in revised form31 March 2014 3 June 2014Accepted 9 June 2014The purpose of this study is to consider the implications of science experiment in class and to seek a direction for its improvement. For this purpose, Science textbooks, teachers’ cognitions, and classroom activities have been analyzed to find out how many and what kind of levels of inquiry elements are included in those. In this study, 22 teachers have participated in the questionnaire to investigate their perception about experiment class, and the two instruction cases in two classes of 9th grade have also been analyzed. Results show that most of the textbooks have included questioning, evidence collecting, explanation of phenomena, and connection with existing scientific knowledge. But the elements of communication and justification have been few. Most levels of the inquiry are teacher-led. Although the teachers thought communication and justification are important, their classroom activities does not coalesce with their thoughts. The students mostly spend their time with connecting evidence, they hardly explain the phenomenon based on the proofs as the results of experiment, and the activities of connection with the existing scientific knowledge, and communication and justification.

Relationship of Using Science Terminology between Science Curriculum and Middle School Science Textbooks in the 2009 National Curriculum

Abstract: Received 26 August 2014Received in revised form30 October 2014Accepted 31 October 2014It is important to know science terminology when learning science. In terms of linguistic and psychological perspectives, the context of encountering a terminology for the first time is critical. If a student has not learned the terminology properly the first time, it might cause misconceptions or be a barrier in following learning. This study aims to identify how careful science terminology are used in science textbooks, and the relationship of using science terminology between science curriculum and middle school science textbooks in the 2009 National Curriculum. In addition, the educational need, the importance of science learning, proper time for teaching, & difficulty of the terminologies have been surveyed among teachers and students. As results of study show, only 25% of terminologies in science textbooks have appeared in the curriculum, and about 10% have been used in middle school science textbooks prior to science curriculum. The survey results suggested that many of those terminologies could cause problems in teaching and learning situation. The solution for them have been divided into the following: avoiding usage in textbook prior to curriculum, using earlier in textbooks, using earlier in curriculum, and reflecting curriculum precisely in the textbook. In general, the curriculum needs to state performing objectives concretely. And it is needed to examine science terminology advertently when writing textbooks.
