교사의 과학관 학습 실행은 개인적 요소와 상황맥락적 요소들 간의 복잡한 상호작용을 바탕으로 이루어진다. 이에 CHAT를 분석 도구로 사용한 사례연구를 통해 두 교사의 과학관 학습 실행을 분석하였다. 연구 결과, 두 교사 모두 활동체계에서 주체 요소와 규칙, 공동체, 분업 요소들 간의 모순에 의해 과학관 학습 실행에 어려움을 겪는 것으로 나타났다. 두 교사는 유사한 모순에 의한 어려움을 겪었으나 과학관 학습 실행의 주체인 교사의 과학관 학습에 대한 인식이나 경험, 과학관 학습 실행에 대한 열정과 동기수준에 따라 갈등에 대한 내면화와 외면화의 양상에는 차이가 있었다. 이는 현장에서 과학관 학습의 활성화를 위해서는 교사가 과학관 학습 실행에 대한 정서적, 사회적 지원을 받을 수 있는 활동체계를 조성하기 위한 노력이 필요함을 시사한다. 한편, 도구요소인 과학관 학습에 대한 연수가 교사의 과학관 학습 실행을 중재하는 데 많은 한계가 있는 것으로 나타났다. 따라서 과학관 학습 관련 연수에서는 학습한 교수전략을 실제로 적용해볼 수 있는 기회와 그에 대한 적절한 피드백을 제공하고, 교사들이 활동체계의 요소들을 과학관 학습 실행에 유리하게 확장하는 것을 도울 필요가 있을 것이다.

In this study, we design a teaching unit that constructs Pascal graphs and extended Pascal triangles to explore number patterns inherent in them. This teaching unit is designed to consider the diachronic process of teaching-learning by combining Dörfler's theoretical generalization model with Wittmann's design science ideas, which are applied to the didactical practice of mathematization. In the teaching unit, considering the teaching-learning level of prospective teachers who studied discrete mathematics, we generalize the well-known Pascal triangle and its number patterns to extended Pascal triangles which have directed graphs(called Pascal graphs) as geometric models. In this process, the use of symbols and the introduction of variables are exhibited as important means of generalization. It provides practical experiences of mathematization to prospective teachers by going through various steps of the generalization process targeting symbols. This study reflects Wittmann's intention in that well-understood mathematics and the context of the first type of empirical research as structure-genetic didactical analysis are considered in the design of the learning environment.

In this study, we investigated and compared the standard of the present teaching tools & facilities in 16 cities and provinces. On the basis of this data, we suggested the standard of teaching tools & facilities according to the new curriculum. In the analysis of the present teaching tools & facilities, we divided the scope of facilities into 'the common one' and 'lab & practical room[common].' This study made it possible to easily recognize a facility by deleting a prep room from the names of facilities. Also, we prepared the standard plan for teaching tools by putting its focus on how to desirably manage the curriculum while giving the independence of a school to the maximum because of all sorts & great numbers of teaching tools.

The purpose of this study was to describe the elementary teachers' teaching behavior procedure in verification-type laboratory instructions. In order to do this, we should know first what constituted the teaching behavior elements in the teachers' instructions, before the teaching behavior can be analyzed. Thirty sets of instructions were recorded and their transcripts were used in this study. The results of this study indicated that the number of teaching behaviors numbered twenty four in total, and that the teaching behaviors could be classified into nine categories, and finally the procedure used in verification-type laboratory instructions generally followed seven steps. These steps can be described as follows; reminding subjects of the preliminary learned concept, presenting inquiry type questions or introducing the main concept, explaining the method used or presenting the predictable outcome/matter for verification, performing lab-based activities, presenting the outcomes, applying the main concept, and finally closing the instruction. For the purpose of promoting more authentic scientific inquiries using these types of instructions, the authors's claims were discussed.

The purpose of this study is to get the more qualified elementary science teacher's guide as a major curriculum material for teachers and to find more improvement suggestions by analyzing of the teachers' perception and using status of it. To examine the problems of this study, 183 teachers from the elementary schools were surveyed by the questionnaire that was developed by researcher, and statistical technique for data analysis was frequency, using SPSS win(version 7.5). Teachers generally thought that the general remarks of the elementary science teacher's guide were helpful to understand elementary science education and the detailed subjects were useful, but teachers less satisfied about 'practice of teaching' of the detailed subjects. The most interested sector of the teachers' was the sector of the teaching methods. The results of this study were that the sector' the methods and evaluation of the elementary science education' of the general remarks and the sector' practice of teaching' of the detailed subjects were mostly interested. So it is necessary to be more detailedly guided when the development of the elementary science teacher's guide are considered.

이 연구의 목적은 과학 교수 학습 방법에 관한 국내 연구 동향을 분석하기 위한 것이다. 국내 학회의 학술지 6종에 게재된 논문들을 연도 방법 대상 주제에 따라 분석했다. 분석대상은 과학교육 분야 문헌들에서 공통적으로 제시하고 있는 방법들을 추출되었다. 분석 결과 과학 교수 학습 방법에 관한 연구들은 2000년 이후 지속적인 증가세를 보였다. 교수 학습 방법 중 실험, 협동학습, 토의가 많이 연구되었다. 이 세 가지 방법에 관한 연구들에서 가장 많이 채택하고 있는 연구방법은 실험연구로 나타났다. 다음으로는 내용분석, 조사연구, 사례연구 등의 순으로 나타났다. 세 가지 방법에 관한 실험연구는 중학생을 대상으로 한 것이 가장 많았다. 특히 실험연구를 통해 과학 성취도, 태도, 탐구능력, 자기효능감과 관련한 과학 교수 학습방법의 효과를 알아보는 것으로 나타났다. 이 연구의 결과를 근거로 볼 때 향후 과학 교수 학습 방법에 관한 연구는 다양한 방법들에 대한 적용 개발 연구 등이 이루어져야 할 것이다. 또한 질적 연구방법을 통해 교수 학습 방법이 실제 교육현장에 적용되는 맥락을 분석하도록 연구 방향이 확대될 필요가 있다고 생각된다. 그리고 다양한 학습자 집단을 대상으로 한 연구를 통해 교수 학습 방법의 효과를 종단적 횡단적으로 접근하려는 시도가 필요할 것이다.

The purpose of this research is to investigate characteristics of science content knowledge and pedagogical content knowledge shown in the primary school science classes. Through analysis of classroom teaching, explore the features and differences between primary and secondary school science PCK. Using open-ended interviews with the teachers and group discussions on a regular basis to analyze and compare classes of five primary school teachers, the relationship between CK and PCK. Regardless of the school level the teacher's PCK and professionalism is required with varying focus and emphasis. The features of the primary school teacher's PCK are as follows: Firstly, elementary teach secondary teach content, teachers value pedagogical knowledge (PK) content knowledge (CK). The primary school PCK requires more of understanding of students and teaching methods that to subject areas. PCK be without content knowledge, and the teacher's PCK is subject-specific In addition to the characteristics of PCK in the primary school science teaching, ways to set up professional exchange or collaboration between primary and secondary teachers, and to provide supplementary in-service training focused on content knowledge for primary school teachers.

Even though many researchers have reported that everyday contexts can arouse students' interests and improve their science learning, the connection between everyday context and physics learning is not yet clearly discussed. In our study, at first, we assumed five guidelines for helping the development of teaching materials for physics learning in everyday context. Based on these guidelines, we developed teaching materials for understanding basic optics and applied these materials to ninth grade students. From the positive responses of students and science teachers about the developed materials, we could confirm that the guidelines were reflected well in the materials. And also, it was found that students and teachers wanted to learn or teach context-based physics in future classroom learning. However, all students do not receive benefits from learning physics in everyday context. By analyzing students' actual learning processes and interviews with them, we found five potential impeding factors which could hinder students' successful learning of physics in everyday context. As a result, we suggested five recommendations for overcoming these impeding factors.
