  • The purpose of this study was to review the studies related to concept learning forcusing on the meanings, kinds, and characteristics of concepts. Then the characteristics of the concepts were analyzed in the three positions: metaphysics, epistemology, and psychology. It was identified that the word 'concept' were confused with the other words such as conception, construct, idea, notion, identity. It was also found that researchers defined the concepts by the use of various meanings. The instructional strategies for scientific concepts were also analyzed in this study. The study found that the instructional strategies for concept learning were developed according to the views about the nature of concepts. Described on the paper are three types of instructional models for science concepts suggested by constructivists as follows: concept formation, concept differentiation, and exchange. They developed the models based on the current research on the misconceptions of major scientific concepts.

  • 이 연구는 연소에 대해 초등교사가 가지고 있는 개념 수준을 파악하는데 그 목적이 있다. 성별, 경력, 6학년 과학교과의 지도 경험, 과학 관련 학력이 고루 분포되도록 하여 12명의 초등교사를 연구 대상으로 선정 하였다. 연구 대상자들에게 5개의 주관식 문항으로 구성된 개념 검사지를 투입하여 개념 정도를 알아본 후, 좀 더 구체적으로 개념 수준 정도를 알아보기 위해 반구조화된 면담을 실시하여 데이터를 수집하였다. 개념 검사지의 내용은 '연소의 정의', '집기병으로 덮었을 때 촛불이 꺼지는 이유', '집기병 속 연소 전과 후의 산소와 이산화탄소', '철솜의 연소', '연소 후 생성물'에 관한 것으로 구성되었다. 그리고 교사별 각 문항에 대한 응답을 과학적 개념(S), 부분개념(P), 오개념(M)의 수준으로 분류하여 정리하였다. 그 결과 모든 문항에서 오개념 또는 부분개념을 가진 교사가 50% 이상이었다. 또한 6학년 과학 교과 지도 경험이 있는 교사들이 경험이 없는 교사들에 비해 연소에 대한 과학적 개념 형성 비율이 높다는 것도 알 수 있었다. 눈에 보이지 않는 기체를 다루는 연소 개념을 눈으로 볼 수 있는 시각화 자료가 개발되어야 하며, 이를 이용해 교사 연수 또는 예비교사 교육이 이루어진다면 교사들의 과학적 개념 형성에 도움이 될 것이다.

  • The aim of this research is clarify the relationship between concept understanding degree about the environment and environmental sensitivity and heighten understanding of environmental education target to pre-service elementary teacher. The subjects of this study are science education intensive course 65 students of B educational university. Concept understanding degree about the environment was separately investigated by 'the definition of environmental education', 'Write The positive concept of the natural environment education and briefly describe.''The negative concept of the natural environment education and briefly describe'. Next clarify the relationship between concept understanding degree about the environment and environmental sensitivity target to pre-service elementary teacher. Based on these results, propose an alternative to cultivate pre-service elementary teacher's knowledge about environmental education. Degree of understanding of the concept environmental education research results are as follows. First, Cognition degree about definition of environmental education of pre-service elementary teacher is correctly recognized generally. Second, They do not think deeply about natural environment when it comes to the positive concept of the natural environment of pre-service elementary teacher. Third, They have only a little interest in natural environment when it comes to the negative concept of the natural environment of pre-service elementary teacher. Correlation research results of degree of understanding of the concept of environmental and environmental sensitivity are as follows. High understanding degree of environmental education is high environmental sensitivity. Heighten environmental sensitivity of pre-service elementary teacher will be sustainable environmental education so education is necessary for environmental Sensitivity training.

  • Recently the concept of learning has become very fashionable among academics from different economic disciplines. Economic geographers and spatial planners joined this fashion by increasingly speaking about the 'learning region'. This paper makes clear that this learning region'. This paper makes clear that this learning region concept has been launched from three angles; as spatial outcome of grand societal changes, as spatial concentration of entrepreneurial learning for innovation and as regional development concept. Despite the deficits and flaws such a young concept is faced with, such as vague definitions, the lack of empirical research and an insufficiently clear separation from existing concepts, the learning region concept might provide economic geography with more insight in agglomeration effects, stronger links with policy-making and more knowledge on path dependency and thus on unravelling the distinction between 'good' and 'bad' industrial agglomerations.

  • The purpose of this study was to suggest that the history of science be introduced to students in the secondary school to help understand the developmental process of the scientific concepts, especially the concept 'heat'. Reviewing the national and international researches related to students' concept 'heat' revealed that many students tend to grasp the wrong concept of heat based on the caloric theory. Studies on definitions and explanations of the concept 'heat' and related concepts in secondary school science textbooks indicated that the way 'heat' was described could not help students to correct their misconceptions. In conclusion we need to include the historical and developmental process of scientific concepts such as heat in textbooks.

  • In this study, concept centered approach and process centered approach in developing integrated science curriculum were compared and compromised between two approaches. It seems that two approaches are in antagonistic relations. The superficial conflictions getween two approaches are not because they are antagonistic in their nature, but because their interesting points are different. The concept centered approahc is interest in fundamental scientific concepts and the process centered approach is interested in scientific enquiry. If science is the composition of enquiry processes and concepts produced by enquiry processes, scientific enquiry process and scientific concept must not be inconsistant. Although concepts are not unchangeable, new concepts and advanced concepts are based on the old concepts. Enquiry activity which is not based on concepts also cannot be significant enquiry. Although fundamental concepts in science is very important, in order to apply concepts to varios phenomena, and to understand concepts more deeply the student should understand concept through the process by which the concepts are derived. As we have discussed above, only the concept centered approach or the process centered approach itself is not complete. Comparing these two uncomplete approaches to integrated science curriculum, we can find out that two approaches are in complementary relations. Because integrated science is based on the idea that natural phenomena should not be understood in fragments, but should be understood as mutually related system' the integrated science curriculum includes both the fundamental scientific concepts and scientific enquiry processes.

  • The purpose of this study was to analyze the concept of physical activity. The method was based on the steps of concept analysis by Walker and Avant(1988). The result of this study were as follows; Upon the concept analysis, physical activity is defined as a series of bodily movements which is performed voluntarily by individual. The defining attributes of physical activity were a series of bodily movements, energy expenditure, goal-directedness, and self-control of the body. The antecedents of physical activity were neuromusculoskeletal function, cardiopulmonary function and cognitive function. And the consequences of physical activity were improvement of physical function, induction of fatigue, and need(physiopsychosocial) satisfaction. Further studies are needed to develop the concept of physical activity using the Hybrid model. In addition, considering personal characteristics it is important to study the facilitating factors of physical activity.

  • The purpose of this study is to analyze the meanings and expressional characteristics of space-time concept in modern architecture. As the architecture spaces reflect and represent the characteristics of times, the meaning and modern expression of space-time concept was studied in the developmental process of space concept on the base of the background of philosophy, science and psychology. At the late 19th century, space concept was changed with relative time-space in philosophy and science and the theory of visual perception. In the beginning of 20th century, space-time concept that combined space with time in the process of image open space expanded movement was developed. In modern architecture, it was expressed as the freedom of movement by open space expanded infinitely and/or abstract space without spacial measure, multiple view point by superimposed and/or polyhedric space and kinetic vision by dynamic and/or continuous space.

  • Earth science is the study to explore the planet in which we live. Among these earth science geology of the area it can be the most critical and important study. However, because of the size and scope is too broad temporal spatial eurona covered in geology is true that many students find difficult about the geology field. In this study, in conjunction with landscape formation of geologic time for the concept to be among the core areas of Geology examined the concept and recognize it as the destination for high school students. Is a test tool for the analysis was adapted for use by Jolley (2010) has developed LIFT (The Landscape Identification and Formation Test). Currently we fix the strip to match the country through a validity check of the curriculum. Results of the study were as follows: First, the ability to check the landscape and formation is expected to estimate the time and the liberal arts students was higher than the natural science students. The reason for this seems to be the influence of learning geographical subjects. Second, the concept of geological time was found to lack both natural science and liberal arts students. The reason is that the students in the previous process because it deals with the concept of geologic time from the top of Earth Science Education II seems to be because there was no chance of learning about geological time. Third, the results confirm the confidence of the students surveyed in the landscape formation time natural science students was higher than liberal arts students. The research measured gender boys higher than girls. Fourth, the students on the landscape and geological time was found to have a number of misconceptions. This appears to be due to the students to feel difficulty in thinking of the concept because the need to understand the abstract geologic time. Therefore, it is necessary just to hold misconceptions about the concept of geology students have through the study of the landscape and geological time.
