조부경 배화여자대학 1987 培花論叢 Vol.6 No.-

This study is to investigate the problems in infant-parent attachment relationship, based on the related literature. First, the concepts of attachment and attachment behavior are defined. Second, the objects of attachment for infant and the influential factors on infant-parent attachment relationship-parental behavior pattern, infant characteristics, social contexts, and duration of contact just after birth are examined. Next, the level of stability in attachment pat-terns, and the last the relationship between patterns of attachment and social competency are considered. The results obtained from this theoretical review are as follows: 1. According to Bowlby and Ainsworth's concept of attachment, attachment refers to the affectional tie that infant forms to his mother. And attachment behavior is the behavior that promotes proximity to or contact with his mother to be attached. 2. The objects of attachment for infant seem to be not only his mother but also his father. Parental affectionate behaviors that are responsiveness, hugging and cuddling more, have an important effect on the security of attachment. In addition, infant characteristics and social support are influential factors. Mother-infant contact in the first few hours of life is not considered critical effect on the development of secure attachment. 3. The secure attachment pattern during infancy tends to be stable care-giving contexts and optimal parent-infant interaction. 4. There is a little significant relationship between attachment pattern and social competency.

김정화,조부경 韓國敎員敎育學會 1998 한국교원교육연구 Vol.15 No.1

요약본 연구는 유아 교사 양성 대학 교육실습시 실습생들 간에 동료 임상 장학이 실시될 수 있는지 그 적용 가능성을 탐색하기 위한 것이었다. 4명씩 4조로 구성된 총16명의 실습생들에게 동료 임상 장학의 기법을 훈련시킨 뒤 정규 실습 기간 중 3주동안 동료 임상 장학을 실시하게 하였다. 삼각측정법에 의하여 자료를 다면적으로 수집한 뒤 분석 기준을 토대로 질적으로 분석한 결과 실습생들은 원만한 인간관계를 형성하고 협의회를 통해 수업 계획안을 구체화시켜 가는 양상을 보였다. 또한 문제 상황에 대하여 개인적 견해나 지도 교사의 시범 수업에 기초하여 분석하였는데 이는 실습생들에게 이론과 실제를 연결짓고 자기 객관화 및 평가 능력을 습득할 수 있는 기회가 되었다. 실습생의 수업 분석 능력이나 시간 부족 등의 제한점이 있었으나 동료 임상 장학은 대체로 실습지도시 실현 가능한 효과적인 방안으로 분석되었다.The purpose of this study was to investigate the implementation process of a peer chinical supervision model in early childhood student teaching. In oder to identify general trends, effects and limits of the implementation process, participant observations and interviews were conducted for 3 weeks in 4 kindergarten classrooms where 16 early childhood student teachers were performing their student teaching. Interview data, field notes, and audio & video tapes were analyzed through three steps. The findings are as follows : During the conferences for peer clinical supervision, the democratic relationship had been spread out among student teachers. They also specified their lesson plans and analyzed their problems based on classroom teachers' model lessons. The peer clinical supervision model was revealed as an ideal method which student teachers could improve their analysis competence and self-evaluation skill eventhough there were some limitations.

유치원, 초등, 중등학교 과학 교재의 '물질의 성질' 관련 학습 내용 전개에 대한 특징 분석

백성혜,조부경,김효남 한국교원대학교 과학교육연구소 2000 청람과학교육연구논총 Vol.10 No.1

이 연구에서는 유치원 제 5차 교육과정과 초등학교부터 고등학교까지의 제 6차 과학교육과정에 근거한 교재들을 분석하고, 제시된 학습 내용의 전개 유형을 파악하고자 하였다. 구체적으로는 유치원부터 고등학교까지의 과학 교재에 제시된 ‘물질의 성질’에 관련된 학습 내용을 분석하였으며, 그 결과 학습 내용 전개 유형을 크게 5가지로 구분하였다. 즉, 개념의 확장 유형, 개념 수준의 심화 유형, 동일한 개념 수준 제시 유형, 다른 과학 개념과 뒤엉킨 유형, 학년간 혹은 학년 내 연계의 단절 유형으로 구분하였다. 이 중에서 ‘개념의 확장 유형’과 ‘개념 수준의 심화 유형’은 학습 내용 전개가 바람직한 것이라고 판단할 수 있지만, 나머지 유형들은 부적절하다고 할 수 있다. 유치원부터 초등, 중등 과학 교재에서 공통적으로 다루는 ‘물질의 성질’에 관련된 7개의 개념을 중심으로 학습 내용 전개 유형을 분석한 결과, 바람직한 유형보다는 부적절한 유형이 더 많이 나타났다. 특히 ‘동일한 개념 수준 제시 유형’은 유치원과 초등학교 전반에 걸쳐서 광범위하게 나타났다. 그리고 바람직한 유형 중에서는 ‘개념의 심화 유형’보다는 ‘개념의 확장 유형’이 더 많은 것으로 분석되었다. 또한 ‘물질의 성질’에 관련하여 유치원부터 제시되는 많은 학습 개념이 중학교 1학년 이상에서 거의 다루지 않는 것으로 나타났다. 특히 이러한 특성을 가지는 개념들은 ‘개념의 심화 유형’으로 내용이 전개되지 않는 공통점이 있었다. 이러한 문제점들을 해결하기 위하여 과학 교재의 내용 구성에 대한 재고찰이 필요하다고 본다. The purpose of this study was to find out the characteristics of learning contents structure of K-12 science textbooks. The characteristics are related to 7 main concepts of matter properties; reaction rate, other reaction, density, solution, state change, absorption, and surface property. The contects are analyzed into 5 types of characteristics; type of concept extension, type of concept deepness, type of same level concept, type of confusion with other concepts, and type of concept interruption. First two types are positive content structures, but the others are negative structures. The findings are as follows. First, a lot of learning contents have the characteristic of 'type of same level concept'. There are few which have the characteristic of 'type of concept deepness'. Second, there are a lot of concepts related to 'properties of matter' which are not represented any more in middle and high school science textbooks. Those concepts are importantly taught in early childhood education and elementary school science. Most of the learning contents don't represent 'type of concept deepness'. Therefore the science textbooks needs to be restructuring.

유아, 초등, 중등 과학교육과정의 연계성 분석을 위한 도구 개발

백성혜,김효남,조부경 한국교원대학교 과학교육연구소 2000 청람과학교육연구논총 Vol.10 No.1

이 연구에서는 과학의 개념 측면에서 유아교육과정, 초등교육과정, 중등교육과정의 연계성 분석에 적절한 도구를 개발하고자 하였다. 교육과정의 개념적 연계성 분석을 위한 도구로 연구의 초기에는 과학의 공통 소재인 ‘물’에 대한 개념도를 개발하였으나, 유치원부터 고등학교까지의 과학교육과정 구성 시각에 큰 차이가 있었기 때문에 통합된 개념도 개발이 어려웠다. 따라서 과학의 한 영역인 화학의 주요 학습 내용이라고 할 수 있는 ‘물질의 성질’에 관한 개념도를 개발하였다. 개발 절차 중에서 유아, 초등, 중등 과학 교육과정에서 다루는 학습 내용의 추출, 학습 내용에 관련된 개념도를 유아, 초등, 중등 과학교육과정 시각에서 개발 및 분석하는 단계는 ‘물’을 중심으로 개념도를 개발하는 초기 단계의 연구에 해당하고, 학습내용에 관련된 유아, 초등, 중등 과학교육과정의 내용 분석, 유아, 초등, 중등 과학교육과정의 개념을 포함하는 개념도 및 분석 표 개발, 개발된 개념도 및 표의수정 및 완성 등 세 단계는 ‘물질의 성질’에 관련된 후기 연구에 해당한다. The purpose of this study was to develop a tool for K-12 science curriculum articulation analysis, especially the concept map of 'properties of matter' and the table of the key concepts of 'properties of matter' by grade. We have 5 steps for the purpose; to extract common subject of K-12 science curriculums, to analyze the contents of K-12 science curriculum related to the common subject, to develop and analyze concept maps of K-12 science curriculums, to develop common concept map and the table of key concepts by grade of K-12 science curriculum, and to modify and clear up the concept map and the table. First two steps are related to the develop of 'water' concept map, and the others are related to the 'properties of matter' concept map.

과학교수능력 향상을 위한 학습공동체에 대한 유치원 교사의 인식

고영미,조부경 이화여자대학교 교육과학연구소 2006 교육과학연구 Vol.37 No.1

본 연구는 과학교수능력 향상을 위한 학습공동체에 대한 유치원 교사의 인식을 알아보기 위한 것이었다. 이를 위하여 학습공동체 및 과학교사교육 관련문헌을 고찰하고 이를 토대로 과학교수능력 향상을 위한 학습공동체에 대한 인식을 알아보기 위한 질문지를 완성하였다. 서울, 충북, 광주, 경북의 4개 기관에서 주관하는 연수에 참여한 유치원 교사 400명을 대상으로 질문지를 배부하여 회수된 질문지 중 329부가 자료 처리 되었다. 연구 결과, 과학교수능력 향상을 위한 학습공동체의 필요성에 대한 유치원 교사의 인식 및 참여의사가 높게 나타났으며, 기본관점 및 목적, 내용 및 방법, 구성원의 조직 및 역할, 운영 체제에 대한 인식은 배경 변인에 따라 차이를 보였다. 이를 볼 때 과학교수능력 향상을 위한 학습공동체를 다양하게 구성하여 유치원 교사의 개별 요구나 변인에 따라 참여하게 하는 것이 바람직하다는 시사점을 얻을 수 있다. The purpose of this study was to investigate the kindergarten teachers' perceptions on learning community for enhancing science teaching competency. The questionnaire based on the related theoretical review, interviews with kindergarten teachers, and the processes of content validity and reliability included 81 items in 8 sub-categories. It was administered to 329 kindergarten teachers who were attending at the in-service programs sponsored by 4 national in-service institutes in Seoul, Chungbuk, Gwangju, and Kyungbuk. This study indicates that the kindergarten teachers need the learning community for their science teaching and have a strong willingness of participating in it. However, depending on their backgrounds they perceive the basic viewpoints and purposes, the contents and methods, the role of participator, and the operating system of learning community differently. These results suggest that a learning community for enhancing science teaching competency should be created based on teachers' developmental levels, requirements, and situations.

Quality Environments for Young Children: DAP, Professionals, and Families : Enhancing Early Childhood Teacher Education through Professional Development School Collaboration

Boo Kyung Cho 한국유아교육학회 2002 INTERNATIONAL JOURNAL OF EARLY CHILDHOOD EDUCATION Vol.8 No.1

This study describes the professional development school movement as a part of attempt to achieve collaboration between university and school as well as how these collaborations are constituted in early childhood teacher preparation programs and kindergartens, and current affairs of early childhood teacher education in Korea. In reviewing related research results, the collaboration between university and school can find the effectiveness in views of offering opportunity for new teaming, changes in teaching concept and practice, sharing leader-ship, and offering qualitative practicum opportunity. Despite the potentials of collaboration, in order to sustain collaboration between university and school, problems of faculty incentive structure , conflict of values, lack of time and budget, high turnover rate of teachers, and resistance to the changes must reach a solution. By embracing such limitations, several plans which can be applied in current early childhood teacher education in Korea, are suggested: Collaboration in the courses related to teaching methods; Formation of collaborating team between cooperating teachers and student teachers in practicum; Connection between graduate school, graduate school of education, and in-service education; Activation of action research; Team teaching between faculty and teacher; Diversity of course management.

Cho, Nariya,Moon, Woo Kyung,Cha, Joo Hee,Kim, Sun Mi,Han, Boo-Kyung,Kim, Eun-Kyung,Kim, Mi Hye,Chung, Soo Young,Choi, Hye-Young,Im, Jung-Gi Radiological Society of North America 2006 Radiology Vol.240 No.1

<P>PURPOSE: To compare prospectively obtained static two-dimensional (2D) and three-dimensional (3D) ultrasonographic (US) images in the diagnostic performance of radiologists with respect to the differentiation of benign from malignant solid breast masses with histopathologic examination as the reference standard. MATERIALS AND METHODS: This study had institutional review board approval, and patient informed consent was obtained. Conventional 2D and 3D US images were obtained from 141 patients (age range, 25-71 years; mean age, 46 years) with 150 solid breast masses (60 cancers and 90 benign lesions) before excisonal or needle biopsy. Four radiologists who had not performed the examinations independently reviewed 2D US images and stored 3D US data and provided a level of suspicion concerning probability of malignancy. The sensitivity, specificity, and negative predictive values of 2D images were compared with those of 3D US images. RESULTS: For all readers, 3D US images were the same as or better than 2D US images in terms of sensitivity (100% vs 100% for reader 1; 100% vs 98% for reader 2; 98% vs 93% for reader 3; 93% vs 92% for reader 4), specificity (58% vs 56% for reader 1; 51% vs 46% for reader 2; 83% vs 72% for reader 3; 86% vs 84% for reader 4), and negative predictive values (100% vs 100% for reader 1; 100% vs 98% for reader 2; 99% vs 94% for reader 3; 95% vs 94% for reader 4). These differences, however, were not statistically significant (P > .05). CONCLUSION: The performance of the radiologists with respect to the characterization of solid breast masses with static 2D US images was similar to that with 3D US data.</P>
