The purpose of this stud was to examine age and gender differences on children's self-concept and agreement between children's self-concepts and inferences by their fathers, mothers and teachers. The subjects for this study were 342 children from kindergarten (n=149) and second grade (n=193), and theirs fathers, mothers and teachers. The results of this study indicated that there was a significant difference among self-concepts by age, but no significant difference by sex. Also, there was no agreement between kindergarteners' self-concepts and inferences by their fathers, mothers and teachers. For second graders, however, noticeable agreement was found, especially between mothers and children.

The concern with scientific mode1s has been growing in science education, and schematic models are frequently used to teach science concepts in secondary schools. The aim of this study is to investigate how well the scientifically gifted students understand scientific concepts through activities of modifying scientific models which we developed. Thirty 8th-grade students participated in the study, 15 in a control group and 15 in an experimental group. For the students in the experimental group, teaching material with activities of modifying models, while for the students in the control group, the teaching material with traditional activities such as explanation, problem solving, and reading. The teaching contents in physics for both groups were linear momentum. We used multiple-choice test and essay-type test to evaluate students' achievements after lessons, and then compared their achievements of both groups. Through the research, we could find a clue that model-modifying activities are helpful for the gifted students to enhance their understanding of physics concepts, although the statistics does not show meaningful difference between experimental and control groups.

The purpose of this study was to investigate the effectiveness of Learning Cycle approach to change the concept of density. The results of the study were as follows : 1) Students already had various types of preconception related to density before formal learning. These preconceptions mostly differ from scientific concepts. 2) Male students were much better than female ones in the development of scientific concepts before formal learning. These differences were found statistically significant(P<0.01). 3) The higher the cognitive level of the students, the better the development of scientific concepts. 4) In the change of preconceptions to scientific concepts by treatment, there was significant difference between control group and experimental group at the 0.05 level. It was found that Learning Cycle approaches were more effective than traditional approaches in acquiring the concept of density. 5) It was found that there was no significant difference On the retention level of the concept of density between control group and experimental group.

In order to clarify and redefine theoretical concepts of consumptions in modern society, the study examines currently enlarging and changing concepts of consumptions. Definitely, the modern society is transferred from industrial society to consumer society, and the meaning of recent consumptions is changed and expanded. In other words, it is important to investigate new cultures and concepts of modern consumptions beyond the fixed perceptions of past consumptions. Today, consumptions in modem society are more than just consumptions. It is not only Physical needs but also Psychological needs of individuals who live in modern society. Hence, this study analyzes and redefines the concepts in modem society's consumptions with respect to set of variables: personal, social, commercial, cultural, and ecological.

The purpose of this study is to propose a new design principles and to analyze the pattern of art and architecture applying fractal concepts. As this study is based on fractal geometry as a natural science, 1 intented to explain the concepts and provide some methods of generating fractal properties. Two major aspects are discussed. Frist, fractals are geometric shapes that are self-similar, in other words, they iterate a basic shape at ever increasing a decreasing dimensions. Self-similarity, irregularity, and scaling are fundamental characteristics of fractal geometry. Second, the fractal concepts of art and design can be analyzed and used as a critical tool. In both criticism and design, fractals provides a tool In fine, fractal geometry can be provided endless possibilities for artists and designers intended in expressing the more complex underlying rhythms and organic patterns of nature.

The purpose of this study is to confirm the possibility of whether learning using a math learning platform can be used to expand students' conceptual structure and to consider how to use it. To this end, first-year middle school students studied using a math learning platform. Then, the concept map created was compared and analyzed with the concept map created before learning to examine the change in the concept structure. The results of analyzing the concept map are as follows. First, the change in the hierarchical structure of the concept appeared as the division of the upper concept was subdivided. However, it has also been changed to comprehensively integrate and simplify higher concepts. The term-centered concept structure has changed to content-centered superordinate and subordinate concepts. In the concept structure, subordinate concepts linked to one higher concept were expanded and differentiated. Second, changes in the integrated structure did not form a linkage structure. The expansion of the integrated structure of concepts through learning using the learning platform was influenced by the composition of the learning contents designed in the learning platform.

Environmentally literated students and adults should be able to use and apply the basic ecological concepts when considering environmental problems and issues. Because ecology forms the foundation of environmental education, a review of the literatures on the degree of students' understanding for ecological concepts can provide useful insights for environmental educators. The purposes of this study were as follows: first, to analyse the parts connected with ecological knowledge of two environmental education books, ‘environments’(middle school) and ‘environmental science’(high school), second, to investigate the level of understanding on ecological concepts by the use of new developed instrument. The 20 most important ecological concepts from Cherrett(1989) and the important ecological concepts' lists from Hungerford and Volk(1990), Ramsey, Hungerford and Volk(1992), Volk(1993) would be recognized and endorsed by most environmental educators as concepts essential to environmental literacy, We referenced these informations and sequenced ecological knowledge as four main categories(communities, populations, ecosystem, man as a component of the nature systems). We have used it as a criterion in the analysis of teaching materials and the development of a new test instrument($\alpha$=0.81). According to the analysed results, the understanding levels for scales and relationships of communities, populations, ecosystem were high but those for individual concepts and differences were low. By the analysis of Korean High School EE book, ‘environmental science’, learning for some concepts(succession, material cycling, niche etc.) has pointed out as one of problems. Environmental educators must pay a careful attention to the concepts that showed high rates of incorrect answer and this work will contribute toward consolidating the basis of EE and help the accomplishment of the ultimate goals in EE.

본 연구는 협동적 상호작용 중심의 교수-학습을 통해서 학습자의 지리개념과 근접발달영역이 어떻게 발달하는가를 살펴보았다. 연구 결과, 학습자의 개념발단은 인지구조 수준이 논아질수록 일상적인 개념에서 벗어나 지리적 개념을 표현하는 과정으로 이루어졌다. 지리적 개념의 표현은 구체적인 사실들에서 하위요소개념. 그리고 기본요소개념의 위계적인 순서로 상향 발달하였으며, 발달 과정에서 학습자가 인지구조로 내면화하는데 가장 어려운 개념은 기본요소개념이었다. 학습자의 수도권 개념에 대한 근접발달영역은 9개 유형으로 나타났다. 근접발달영역은 사전 인지구조가 지리적 개념을 얼마나 더 많이 그리고 더 체계적으로 표상하는가의 질적 차이에 따라 다르게 발달했다. 지리개념 발달은 학습자의 사전 인지구조보다는, 교수-학습을 통해서 자신의 인지구조를 얼마나 적극적이고 능동적으로 재구성하느냐에 달려 있었으며, 표상한 개념의 양적 증가를 바탕으로 한 질적 변화의 과정으로 이루어졌다.

In order to prepare for the coming twenty first Century and to meet changing societal dedmands and health needs, it is necessary to develop a new conceptual framework for curriculum the colleges of nursing. The specific objectives of this project were to ; 1) address the problem areas of the existing curriculum which were identified in the first phase of this study ; 2) develop a conceptual framework which will meet faculty, student and societal needs : and 3) identify the content of the curriculum In order to accomplish the objectives, the curriculum committee held 30 weekly meetings during the period of October, 1992 and December, 1993, There also were two workshops with college of nursing faculty members. The Philosophy and objectives of education were revised on the basis of the essential concepts of nursing : human being, nursing, environment, and health. From these basic concepts, six essential components were identified for the conceptual framework. These were nuring process, communication, professional roles, client, and nursing. These six components are interrelated in the curriculum. The complex interrelationship among the six components were presented on horizontal and vertical axes. Concepts related to steady improvement were put on a vertical axis. For example, concepts of client, health, and nursing are included in all levels of nursing curriculum and students are expected to retain and accumulate more complex contents as they progress in curriculum. Concepts on the horizontal axis are nursing process, communication, and professional roles. These concepts are unique to nursing and are common to any level of curriculum. Students are expected to study these concepts through all levels of the curriculum. It is expected that the objectives of the college of nursing will be accomplished when the courses and content of the curriculum are based on this conceptual fremework.
