과학 고등학교와 일반 고등학교 학생들을 대상으로 시스템 사고측정 도구의 타당도 검증 및 시스템 사고 비교

이 연구의 목적은 이효녕 등(2013)에 의해 개발된 시스템 사고 측정 검사지의 타당도 재검 및 시스템 사고 측정 검사지를 활용하여 과학영재학생과 일반학생의 시스템 사고에 유의미한 차이가 있는지 알아보는 것이다. 과학고등학교 학생 116명과 인문계 고등학교 학생 553명에게 시스템 사고 측정 검사지를 투입하고 SPSS 18.0을 활용한 탐색적 요인분석과 Amos를 활용한 확인적 요인분석을 실시하였다. 그리고 SPSS 18.0을 활용해 과학영재학생과 일반학생 두 집단의 검사지 평균을 독립표본 t-test를 수행하여 시스템 사고에 유의미한 차이가 나타나는지 살펴보았다. 탐색적 요인분석 결과 5개의 요인구조가 나타났으며 각 요인별 4문항씩 적재되었다. 시스템 사고 측정도구의 전체 신뢰도는 .875였으며, 각 하위 요인의 신뢰도는 .693~.751로 신뢰로운 검사지로 나타났다. 확인적 요인분석에서도 <TEX>${\chi}^2/df$</TEX>값이 2.765, TLI는 .907, CFI 는 .929, IFI는 .930, RMSEA는 .044로 모형 적합도 5개 수치에서 적합한 값을 보여주어 모형을 수용할 수 있다. 그리고 과학영재학생과 일반학생의 시스템 사고를 t-test를 이용해 비교해 본 결과 시스템 사고 전체 문항 뿐 아니라 모든 하위 영역에서 과학영재학생이 일반학생에 비하여 우수한 시스템 사고를 하고 있음을 보여주었다. 이 연구가 더 낳은 성과를 얻기 위해서는 학생들의 시스템 사고 향상을 살펴보는 연구에서 다른 질적 연구 도구와 함께 활용될 필요가 있으며, 나아가 다양한 학교 급에 적용 가능한 시스템 사고 측정 도구도 함께 개발될 필요가 있다. The purposes of this study are 1) to revalidate the developed Measuring Instrument Systems Thinking and 2) to compare systems thinking skills between gifted and non-gifted high school students. For the test, 116 gifted science students and 553 non-gifted students were sampled from high schools. Exploratory factor analysis and confirmatory factor analysis were performed and Independent t-test was performed using the average of the two groups. The finding of the exploratory factor analysis indicated 5 factors in the model with 4 items per single factor. The result of confirmatory factor analysis was generally appropriate and acceptable (5 factor model: <TEX>${\chi}^2/df$</TEX> : 2.765, TLI=.907, CFI=.929, IFI=.930, RMSEA=.044). The reliability for 20 items turned out to be high because the Cronbach's alphas were at .875 and .693~.751 per each factor. In addition, the result of t-test showed that systems thinking skills among gifted science students were significantly higher than non-gifted students. This study could be expanded to measuring systems thinking with qualitative research tools and to various school levels.

중등 초임 과학영재교육 담당교사의 코티칭 과정에서 나타나는 과학 수업 반성의 특징 분석

이 연구에서는 사례연구를 통해 중등 초임 과학영재교육 담당교사의 코티칭 과정에서 나타나는 과학수업 반성의 특징을 조사했다. 중등 과학영재교육 경력이 5년 미만인 초임 교사 2인을 선정하여 총 3회에 걸친 9차시의 과학영재수업을 공동으로 계획, 진행, 평가하도록 했다. 두 교사의 모든 코티칭 과학영재수업을 참관했고, 반성대화 전사본과 반성일지를 Davis(2006)가 제안한 '생산적 반성'의 관점에서 분석했다. 연구 결과, 자료의 종류 및 수업 차수에 관계없이 두 교사의 수업 반성 과정에서 모두 '과학영재 교수전략 및 지도'와 '과학영재학생' 측면이 비교적 많았다. 두 측면보다 적긴 했지만 '과학영재 교육과정' 측면에 대한 반성의 빈도도 낮지 않았다. 그러나 '과학내용지식'과 '과학영재교육 평가' 측면에 대한 반성은 매우 적었다. 통합 수준에 대한 결과에서는 두 교사의 반성 과정에서 과학영재수업의 5가지 측면 중 2~4가지 측면이 다양한 형태로 통합되어 있었다. 특히 '과학영재 교수전략 및 지도'나 '과학영재학생' 측면과 다른 측면이 통합된 경우가 많았다. 이런 경향은 과학영재교육 경험이 더 많은 교사에게서 강하게 나타났으며, 이 교사의 경우에는 '과학내용지식'과 다른 측면이 통합된 경우도 적지 않게 나타났다. This study investigated secondary beginning science-gifted education teachers' reflection on their science teaching through coteaching with the case study. We selected two beginning teachers whose teaching careers in secondary science-gifted education were less than five years. The teachers planned, performed, and reflected together their science teaching for science-gifted students during nine class hours over three times. We observed their science classes through coteaching, and analyzed the transcripts for reflective discussions between them and their reflective journals in terms of 'productive reflection,' a concept suggested by Davis (2006). The results revealed that the aspects of 'instructional strategies and instruction for science-gifted education' and 'science-gifted students' were most frequently included in their reflection processes on science teaching, regardless of the type of data and the class time. 'Curriculum for science-gifted education' were also frequently included although fewer than two previous aspects. However, 'subject matter knowledge' and 'assessment' was hardly included. Two to four aspects among five aspects of the science teaching for science-gifted students were variously integrated in their reflection processes. Especially, the integrations between 'instructional strategies and instruction for science-gifted education' or 'sciencegifted students' and the other aspects were most frequent, and this tendency was stronger in more experienced teacher in science-gifted education. The integrations between 'subject matter knowledge' and the other aspects were often included in the more experienced teacher's reflection processes.

불일치 상황의 활용을 통한 초등 과학영재학생들의 과학에 대한 인식론적 신념 분석

이 연구에서는 초등 과학영재학생들의 불일치 상황에서의 대처 전략 및 원하는 교사 지도 전략 유형을 조사한 후, 이에 기초하여 그들의 과학에 대한 인식론적 신념을 분석했다. 이를 위해, 초등학교 5~6학년 과학영재학생 72명을 대상으로 개방형 설문을 실시했다. 일부 학생들을 대상으로 심층 면담도 실시했다. 연구 결과, ' 포기', ' 교사에게 도움 요청', ' 같은 방법으로 다시실험', ' 다른방법으로 다시실험', ' 능동적인 원인 분석 후 다시 실험', ' 실험 결과 인정', ' 실험결과 설명'이라는 7가지 불일치 상황에서의 대처 전략 유형이 나타났다. 원하는 교사 지도 전략의 경우에는 '격려', ' 성공적인 실험 결과 제시', ' 설명', ' 같은방법으로 다시 실험하는 기회 제공', ' 다른 방법으로 다시 실험하는 기회 제공', ' 능동적인 원인 탐색 기회나 도움 제공', '실험 결과 설명 기회나 도움 제공'의 7가지 유형이 나타났다. 이 14가지 유형들을 지식에 대한 인식론과 관계에 대한 인식론 차원에 기초하여 '사실 전달', '사실 구성', '의미 전달', '의미 구성'의 네 가지 관점으로 다시 분류했다. 이런 결과에 대한 교육적 함의를 논의했다. This study investigated the types of elementary science-gifted students' coping strategies and teachers' desired teaching strategies in anomalous situations. Their epistemological beliefs about science were then analyzed on the bases of the types. To do this, 5th and 6th year science-gifted students (N=72) were asked to respond to an open-ended question with some of them being interviewed deeply. The analyses of the results indicated seven types of coping strategies in anomalous situations and were identified as follows: Abandoning, asking a teacher for help, trying the experiment again with same methods, trying the experiments again with different methods, trying the experiment again after actively analyzing the causes, recognizing the experimental results, and explaining the experimental results. Seven types of teachers' desired teaching strategies emerged and were also identified as follows: Encouraging, providing successful experimental results, explaining, providing the opportunity for trying the experiment again with same methods, providing the opportunity for trying the experiments again with different methods, providing the opportunity and help for trying the experiment again after actively analyzing the causes, and providing the opportunity and help for explaining the experimental results. The fourteen types were grouped again into four categories such as 'transferring facts', 'constructing facts', 'transferring meanings', and 'constructing meanings' on the bases of the epistemological beliefs toward knowledge and the epistemological beliefs toward relation. Educational implications of these findings are discussed.

문제해결형 탐구학습에 대한 인식과 학습이 실험 설계 능력에 미친 효과 : 과학 영재학생들에 대한 사례 연구

이 연구는 과학자의 연구과정을 반영한 문제해결형 탐구학습 프로그램을 이용하여 고등학교 과학 영재학급 학생들을 대상으로 수업을 한 후, 문제해결형 탐구활동 수업에 대한 학생들의 인식, 활동 내용 및 수업의 효과를 분석한 것이다. 이를 위해 고등학교 부설 영재학급 1학년 학생 12명을 대상으로 사전 실험설계 능력 검사(DCT)를 한 후, '주기가 일정한 흔들이 만들기', '표면성장 실험', '메트로놈의 동기화현상'의 세 모듈을 적용하여 수업을 하였고, 그 후 사후 실험 설계능력 검사, 설문과 학생 면담을 실시하였다. 각각의 모듈은 과학적 의문의 생성, 해결 방안 모색을 위한 실험설계, 문제 해결 활동과 같은 일련의 과정들로 이루어져 있어 이를 통해 학생들이 문제해결형 연구 형태를 경험할 수 있도록 하였다. 조사 결과 학생들은 주어진 과정에 따라 기계적으로 하는 기존의 학교 수업과는 달리 자기주도적으로 실험을 설계하고, 해결 방안을 다양한 각도로 모색하여 직접 문제를 해결한다는 점에서 문제해결형 탐구 활동과 기존 수업과의 차별성을 인식하였다. 수업 과정 중 학생들은 발견한 문제를 해결하기 위해 끊임없이 사고하고 실험을 설계 해 보고, 직접 실험을 수행하면서 마침내 처음에 발견했던 문제를 해결할 수 있었다. 이러한 반복적인 과정을 통해 학생들은 과학자의 연구과정의 한 형태를 경험할 수 있었으며, 문제 해결형 연구과정에 대한 이해를 바탕으로 과학자의 연구과정에 대한 인식의 변화도 생겼음을 확인할 수 있었다. 수업의 효과 면에서 본 프로그램은 학생들의 체계적인 실험설계 능력의 향상, 현상의 원인에 대해 자유롭게 생각해 보고 의견을 발표하는 기회를 갖게 한 점 등에서 학생들에게 긍정적인 영향을 미친 것으로 보인다. 실험 설계 능력 사전 사후 검사 점수를 비교한 결과, 수업 후 대부분의 학생들은 실험설계 능력에 향상을 보였다. 기존의 따라 하기 식 실험에 익숙해져 있던 학생들은 처음에는 스스로 실험을 설계하는 데 다소 어려움을 느꼈지만 두 번째, 세 번째 수업을 하면서 체계적으로 실험을 설계하여 문제를 해결해 나가는 데에 조금씩 익숙해진 것을 확인할 수 있었다. We developed problem-solving type inquiry learning programs reflecting scientists' research process and analyzed the activities of science-gifted high school students, and the understanding and the effects of the programs after implementation in class. For this study, twelve science-gifted students in the 10th grade participated in the program, which consisted of three different modules - making a cycloidal pendulum, surface growth, and synchronization using metronomes. Diet Cola Test (DCT) was used to find out the effect on the improvement of the ability to design experiments by comparing pre/post scores, with a survey and an interview being conducted after the class. Each module consisted of a series of processes such as questioning the phenomenon scientifically, designing experiments to find solutions, and doing activities to solve the problems. These enable students to experience problem-solving type research process through the program class. According to this analysis, most students were likely to understand the characteristics of problem-solving type inquiry learning programs reflecting the scientists' research process. According to the students, there are some differences between this program class and existing school class. The differences are: 'explaining phenomenon scientifically,' 'designing experiments for themselves,' and 'repeating the experiments several times.' During the class students have to think continuously, design several experiments, and carry them out to solve the problems they found at first. Then finally, they were able to solve the problems. While repeating this kind of activities they have been able to experience the scientists' research process. Also, they showed a positive attitude toward the scientists' research by understanding problem-solving type research process. These problem-solving type inquiry learning programs seem to have positive effects on students in designing experiments and offering the opportunity for critical argumentation on the causes of the phenomena. The results of comparing pre/post scores for DCT revealed that almost every student has improved his/her ability to design experiments. Students who were accustomed to following teacher's instructions have had difficulty in designing the experiments for themselves at the beginning of the class, but gradually, they become used to doing it through the class and finally were able to do it systematically.

지구와 달 표면에서 물체의 운동에 대한 일반 중학생들과 과학영재학생들의 개념

이 연구는 지구와 달 표면에서 물체의 운동에 대한일반 중학생들과 과학영재학생들의 개념을 조사하였다. 연구 대상은 일반 중학교 중학생 1학년 61명, 2학년 51명, 3학년 51명 총 163명과 대학부속 과학영재교육원 중등 과학영재학생 32명으로 하였다. 연구 내용은 지구와 달 표면에서 연직, 경사면, 수평면에 따른 물체의 운동에 대한 개념으로 하였다. 각각 지구와 달 표면에서 크기는 같고 질량이 다른 두 물체를 동시에 놓거나, 같은 속력으로 위쪽으로 던지거나, 수평면에서 굴렸을 때 '어느 것이 먼저 도착하는가?'를 조사하였다. 지구와 달 동시 상황에서는 같은 물체를 지구와 달 표면에서 동시에 놓거나, 던지거나, 굴렸을 때 '어느 장소에 먼저 도착하는가?'를 조사하였다. 연구결과 과학영재학생들이 일반 중학생들 보다 지구 표면에서 연직, 경사면, 수평면의 모든 조건에서 물체의 운동에 대한 개념에 유의미한 차이가 있었고, 달 표면에서 연직 위 방향에서 물체의 운동에 대한 개념에 유의미한 차이가 있었다. 지구와 달 표면 동시 상황에서는 연직 아래 방향에서 물체의 운동에 대한 개념에 유의미한 차이는 없었고, 연직 위 방향, 경사면, 수평면에서 물체의 운동에 대한 개념에 유의미한 차이가 있었다. 연구 결과를 통해서 얻은 결론은 첫째, 지구와 달 표면에서 물체의 운동에 대한 설명을 할 때 진공에 대한 의미와 중력의 크기에 대한 학습이 먼저 이루어져야 한다. 둘째, 중학생들에게 다양한 상황과 조건에서 물체의 운동을 통합적으로 이해하도록 지도해야한다. 셋째, 중학생들은 상황을'동일시'하려는 사고 경향이 있다. 마지막으로 힘과 물체의 운동은 물리 영역에서 매우 중요한 단원이며, 교사가 물체의 운동을 설명할 때 위 결과들을 유념해서 가르쳐야 한다. The purpose of this study was to investigate middle school and science-gifted students' conceptions about motion of objects on the surface of the earth and the moon. The subjects were 61 first-, 51 second-, 51 third-year students, for a total of 163 in a middle school and 32 science-gifted students from a university-affiliated sciencegifted education center for secondary school students. The research contents were conceptions about motion of objects by the vertical direction, an inclined plane and horizontal plane on the surface of the earth and the moon. The questions were as follows: If two balls, same size but different mass, were put on, thrown over, by the vertical direction, an inclined plane and a horizontal plane on the surface of the earth and the moon at the same time and speed, which one would arrive faster than the other?; In the same mass in the earth and the moon, how fast could the object reach to which location, the earth or the moon? The results showed that science-gifted students offer meaningful difference on the concept of objects in motion at the vertical direction, an inclined plane and a horizontal plane on the earth and at the vertical direction on the moon than general middle school students. There were meaningful difference on the vertical up direction, an inclined plane and a horizontal plane in the same situation in the earth and the moon. Finally, based on the results of our study, we discuss possible educational implications for teaching the concept of objects in motion.

과학영재에게 요구되는 핵심역량에 대한 교사와 학생 인식

본 연구는 과학영재들이 미래의 과학자로서 성공적인 삶을 영위하고, 높은 성취를 달성하기 위해 길러주어야 할 핵심역량에 대해 과학영재 학생들과 교원들을 대상으로 인식을 조사하였다. 이를 위해 과학영재 학교에서 요구되는 16가지 핵심역량 항목을 도출하고 각 항목에 대해 중요도와 학생의 현재수준을 비교 분석하여 핵심역량에 대한 교육적 요구도를 살펴보았다. 그 결과 첫째, 핵심역량 수준에 대해 교사는 사고력을 가장 높게 평가하였지만 학생들은 연구 및 탐구능력을 가장 높게 인식하였다. 그리고 교사는 협동능력을 가장 낮게 평가하였지만 학생들은 자기효능감을 낮게 평가하였다. 둘째, 교사들은 자기주도적 학습태도, 사고력, 교과에 대한 흥미, 학습동기가 과학영재 들에게 길러주어야 할 중요한 역량으로 지각하였으며, 자기조절능력, 협동정신, 자기주도적 학습태도에 대한 교육적 요구 수준이 높은 것으로 인식하였다. 끝으로 과학영재에게 요구되는 핵심역량기반교육에 대한 시사점을 논의하였다. The purpose of this study was to investigate core competencies of science-gifted students based on teachers' and students' perceptions. Based on a literature review and focus group interview, 16 core competencies of science-gifted students were drawn. The results of this study were as follows. First, there are significant differences in self-control, self-directed learning, knowledge in one's academic area, research, English, writing, leadership, communication skill, cooperation, and spirit of services between teachers and students. Second, teachers perceived self-directed learning, thinking skills, interests in one's academic area, motivation as the most important core competencies among the 16. Also, teachers perceived the educational program to raise self-control, cooperation and self-directed learning. Further discussion was reviewed.

역동적 과학 평가를 통한 초등과학 영재들의 전기회로 개념 이해 과정 분석

The purpose of this study was exploring instructive methods to make each gifted child`s ability develop as more by selecting the dynamic method instead of existing static method in teaching and evaluating science-gifted students in elementary school and by analyzing conceptual change of electric circuit. In this research, 11 science-gifted students in primary school were chosen, and Dynamic Science Assessment(DSA) intended to comprehension of scientific electric circuit concept was performed as focusing on scaffolding aspects in order to find the transition process. And then, the features on transition process of students` concept were analyzed in quality. The results of the study were checked that the features of useful scaffolding input with respect to comprehending concepts of science gifted-students by using DSA. The less familiar to approach the subjects, the more presented numbers of scaffolding showed. As coming toward transition and same questions, scaffoldings (interactions) were declined because their level of transition was higher than before. Various ways were used in helping the students comprehend the concept on the method of connecting electric circuit and the emitting amount of current, which acted to adapt to daily life.

초등 영재학생의 영재학급과 일반학급에서의 교우관계 분석

Peer relationships in young students` communities are one of the important factors influencing the cognitive and affective domains of learning. Moreover, students who join the special program for gifted students possess differential peer relationships from the students in general classes. This study aims to explore the differences of 5th grade five science-gifted students` peer relationships between students in special classes for gifted students and general classes. Five students in the special program for gifted students, managed by the Office of Education in a southern city, participated in this study. Social network analyses were utilized to explore participants` peer relationships; the students` homeroom teacher was interviewed to explore the contextual and in-depth characteristics of gifted students` peer relationships. The results illustrated four cases of peer relationships: (1) smart loner (2) my study mate (3) I`m the best in my class, and (4) a good friend anywhere. This study identified that the gifted students possessed diverse peer relationships in both the special program and general classroom. In addition, this study suggests that the program for gifted students needs to be specially designed based on the gifted students` peer relationship.

언어 네트워크 분석법을 통한 중학교 과학영재들의 사실, 가설, 이론, 법칙과 과학적인 것의 의미에 대한 인식 조사

The importance of teaching the nature of science (NOS) has been emphasized in the science curriculum, especially in the science curriculum for science-gifted students. Nevertheless, few studies concerning the structure and formation of students` mental model on NOS have been carried out. This study aimed to explore science-gifted students` understanding of `fact`, `hypothesis`, `theory`, `law`, and `scientificness` by utilizing semantic network analysis. One hundred ten science-gifted middle school students who were selected by a national university participated in this study. We collected students` written responses of five items and analyzed them by the semantic network analysis(SNA) method. As a result, the core ideas of students` understanding of `fact` were proof and reality, of `hypothesis` were tentativeness and uncertainty, of `theory` was proven hypothesis by experimentation, of `law` were absoluteness and authority, and of `scientificness` were factual evidence, verifiability, accurate and logical theoretical framework. The result of integrated semantic network illustrated that the viewpoint of science-gifted students were similar to absolutism and logical positivism (empiricism). Methodologically, this study showed that the semantic network analysis method was an useful tool for visualization of students` mental model of scientific conceptions including NOS.

코티칭을 통한 초임 과학영재교육 담당교사의 수업 전문성 변화에 관한 사례연구

As a case study on the changes of beginning science-gifted education teachers` teaching professionalism through coteaching, this study deeply investigated the change processes in the aspects of pedagogical content knowledge. We selected two beginning teachers whose teaching careers in secondary science-gifted education were less than five years. The teachers planned, performed, and reflected together their science instructions for secondary science-gifted students during nine class hours over three times. We observed coteaching of science instructions of the teachers, and analyzed the taped videos, the materials, the transcripts for discussions between them and in-depth interviews with them, their reflective journals, and researcher`s field notes by using the constant comparative method. This study revealed that the coteaching positively changed the two teachers` practical knowledge about the curriculum for science-gifted education, the instructional strategies for science-gifted education, the assessment in science-gifted education, the science-gifted students, and the science contents although there were some limitations. The results suggest that the coteaching will be useful in improving beginning teachers` teaching professionalism, and provide practical implications in finding the ways to use it effectively in science-gifted education.

중등 과학영재교육에서 초임 교사의 수업 전문성 제고 전략으로써의 멘토링 적용 사례연구

As a case study on the use of mentoring as a method of improving novice teachers` teaching professionalism in secondary science-gifted education, this study investigated the characteristics of mentoring science instructions for science-gifted students at the plan, performance, evaluation, and post-mentoring stages of the classes. One mentor and two mentees were selected, and mentoring in each mentee`s instructions was conducted during nine classes over three times. We observed the total classes, and analyzed taped videos, the materials, the transcripts for mentoring and in-depth interviews, and field notes. The analyses of the results indicated that the characteristics of mentoring instructions, at the planning stage of the classes, exhibited the construction of more systematic classes, the escape from the schema that science instructions for science-gifted students were instructions using somewhat difficult experiments and the uses of diverse teaching strategies, the influence of the psychological burdens on developing science-gifted education programs, and the increase of the time preparing the classes. At the performance stage of the classes, the characteristics included the improvement in the quality of the classes, the influence of the psychological burdens on teaching the classes, and the inducements of some confusion on performing them. At the evaluation stage of the classes, the characteristics included the provision of the opportunities in deeply reflecting my own classes, and the provision of the practical power for improving the classes. Finally, the characteristics at the postmentoring stage could be attributed to the increase of mentees` self-confidence about their instructions and some development of mentors` teaching professionalism/mentoring skills.

중학교 과학영재와 일반학생의 Peer Instruction을 통한 인지갈등: 문항의 난이도에 따른 비교를 중심으로

This study compared the cognitive conflict on peer instruction concerning the level of difficulty in question, between middle school science gifted students and non-gifted students. For the study, 35 the 7th grade science-gifted students in the organization affiliated with Science Education Institute for the Gifted in Seoul and Gyeong-gi province, and 14 the 8th grade science-gifted students, and 71 the 8th grade students. They performed peer instruction on propagation of straight light and composition of light and then, discussed three concept problems. After discussing the students took paper pencil test about changing levels of cognitive conflict. Regardless of the level of difficulty in question, the science-gifted students showed meaningful decreased figures on cognitive re-evaluation factors after peer-discussion. They trusted their peers, so during discussion, they explained their concepts. Furthermore discussion process enabled them to do reflective thinking. consequently, discord of students dropped, and total figures of cognitive conflict also declined. Science-gifted students have a tendency to worry lower than general students, though they felt anxiety as difficulty of the problems after peer-discussion. Through peer-discussion, science-gifted students presented statically decreased anxiety factors. By means of analyzed results of changing cognitive conflict of science-gifted students, developing and adapting strategies of cognitive conflict considering learner characteristics of science-gifted students is needed.
