This study dealt with two case studies of the development of beginning science teachers' pedagogical content knowledge (PCK). This study was grounded on the idea that teacher thinking and classroom behavior are related to each other in a reciprocal way. Teachers' PCK influences teaching practices, while in a reverse way teaching activities influence teachers' practical knowledge. Two beginning science teachers participated in this study. Data collection consisted of classroom observation, interviews, reflective journals and lesson plans. For data analysis, we conceptualize pedagogical content knowledge for science teaching as consisting of four components: (a) knowledge about science matter, (b) knowledge about students' understanding of science topics, (c) knowledge about instructional strategies for teaching science, (d) knowledge about assessment in science. The outcomes of this study revealed that there was a large gap between beginning science teachers' intentions for teaching science and their practice. To give beginning teachers more opportunities to incorporate their knowledge base for teaching, we propose that they need to be involved in a real teaching situation at schools rather than in the university.

The present study is to analyze the arguments about the generation of declarative scientific-knowledge in the philosophy of science and invent a structured model of the process of scientific-knowledge generation with the types of the generated scientific-knowledge. The invented model shows that scientific-knowledge generation is a distinctive process with the processes of inductive, abductive, and deductive thinking. Furthermore, inductive process is included with observation, which is consisted of simple observation and operative observation, and rule-discovery which is involved with the processes of commonness discovery, classification, pattern discovery, and hierarchical relationship. Also, abductive process has two components. One component generates question and second component generates hypothesis in which the process consists of representing question situation, identifying experienced situation, identifying causal explicans, and generating hypothetical explicans. Finally, deductive process is involved with logical inventing test method and evaluation criteria, concrete inventing test method and evaluation criteria, evaluating hypothesis, and making conclusion.

The International Astronomy Olympiad (IAO) was established and its foundation were published by the Euro-Asian Astronomical Society (EAAS), in order to spread astronomical knowledge, promote international cooperation in astronomical education area, and recognize the importance of astronomy in far-reaching field of science and human culture. In 1996, the first IAO was held at the Special Astrophysical Observatory (SAO) of the Russian Academy of sciences (RAS) located in the north Caucasus of Russia. Since then, it has been held every year. Here, we will describe the present status of the International Astronomy Olympiad, its major results by year, related institutions, organizations, and the main regulations regarding its operation. In order to measure the levels of scientific knowledge and thinking abilities, we develop a rubric to analyze the characteristics of problems in the IAO with regards to cognitive aspects of scientific inquiry. These problems require high levels of content knowledge and scientific method knowledge. Also high order thinking abilities and high levels of convergent thinking skills, instead of divergent, are needed to solve these problems. Thus, the problems presented are set a high difficulty. Through this analysis, we can understand main purpose of the International Astronomy Olympiad and explore the future direction of the Korea Astronomy Olympiad.

The purpose of this study is to review the expanded role of authority files, which uses the Knowledge Organization System(KOS) to organize contents and manage the collections in digital libraries. The KOS plays a role as a bridge between the users' information needs and materials by providing links between catalogs and digital resources on the web and supporting retrieval of the relevant items. It is described how a KOS can be used to link a digital resource to related materials, to provide more descriptive records for entities, and access to relevant physical objects.

인간이 생각하고 지식이 습득되어지는 방법에 대한 이해는 인지과학자들에게 항상 중요 관심사이다. 학교교육이 전개된 후의 학생들을 대상으로 한 인지과정을 탐구하는 것은 쉽지 않다. 본 논문에 유아기 유아들을 대상으로 과학적인 표상능력을 이용하여 유아의 인지구조를 고찰하였다. 5세 유아 120명을 대상으로 2년간 주변에서 흔히 볼 수 있는 곤충류를 관찰할 수 있도록 한 후, 그림 그리기와 언어 표현 방법을 이용하여 유아들의 인지과정이 탐구되었다. 유아들은 1차, 2차 표상과정을 통해 기존에 갖고있던 사물에 대한 개념에 분명한 변화를 보였다. 본 연구결과는 유아들의 과학지식 형성에 대한 인지과정을 기술하며, 과학적 지식으로 확장될 수 있는 효율적인 지도 방법을 제공한다.

This research is that it could use a theory from a .cognitive science, making a hypothesis to explain the thingking steps of designing, adapting the problem solving of the design from knowledge of a cognitive science, to meet the possiblity which it can be developed the new way of the thinking. Design is a field where it needs a complexity with hi-brain activities. And cognitive science is a science which it study human brain activities. However, it is also quite possible to bo adaped over all design by linking with design and cognitive science. I explaned the ideation of the thinking steps on this study by the knowledge of cognitive science, to observe to be possible. I found out the new ways of possibilities from design thinking process. It is a result that I've been interpretated the design process and the thinking process out of the theory of knowledge structure.

The purpose of this study is to develope a model for an integrated national management system of information services in the science, technology and industry sectors by assigning major roles and purposes to KISTI which was set up by the merge of KINITI and KORDIC. In order to develope the model, this study investigates and analyzes the problems of KINITI and KORDIC. On the base of these analytical results, this study presents a desirable model of KISTI for a national information services in the science, technology and industry sectors.
