The purpose of this study was to discuss the example that developed geometry model textbook based on storytelling using real-life context. To achieve this purpose, we first elaborated the meaning of the textbook based on storytelling with real-life context, and then we discussed the outline of the story and the summary of each lesson. This study defined the storytelling textbook with real-life context as the textbook consisting of activities that explored and organized mathematical concepts by using real-life situations as materials of stories. The geometry textbook we developed employed two real-life materials, a map and a set square: we used a map for the coordinate geometry and a set square for the equation of a line. To attract students' interest, we introduced confrontation between a teacher and two students and a villain. We implemented experimentation with the textbook based on storytelling in order to verify its validity. The participants were 25 students that were enrolled in a high school in Seoul. Among them, 17 participants were surveyed. Students' answers from the survey questionnaire suggested that the geometry textbook we developed based on storytelling helped them learn mathematics and that the instruments such as a map and a set square helped them understand mathematical concepts. However, their opinion implied that the story of the textbook needed to be improved so that the story reflected more realistic contexts that were familiar with students.

과학과 기술이 발전할수록 나노크기를 넘어서 나노 크기미만의 관찰 분해능과 가공능력이 필수로 요구되어 측정장비와 가공장비의 연구 및 개발이 매우 중요하다. 현재는 주사전자현미경과 투과전자현미경의 발달로 나노크기 이하의 이미징 분해능에는 도달하였지만, 전자 입자의 가벼운 무게 때문에 가공측면에서는 한계를 가지고 있다. 또한 지난 수십 년간 정밀가공에 사용된 갈륨이온 LMIS(Liquid Metal Ion Source)기반의 집속이온빔 시스템은 수십 nm의 가공정밀도를 가지지만 10 nm 미만의 가공정밀도까지 구현하기에는 현재 기술적인 한계로 힘들다. 나노크기 이하의 이미징 분해능과 수 nm의 가공정밀도를 갖는 이온현미경이 최근에 상용화되어 판매되고 있는데, 이 이온 현미경에 사용되는 것이 가스장 이온원(GFIS:Gas Field Ionization Source)이다. 가스장 이온원은 작은 발산각, 작은 가상 이온원 크기 그리고 좁은 에너지 퍼짐의 특징을 가지며 이에 따라 구면수차 및 색수차에도 둔감한 특징을 가지고 있다. 또한 LMIS 는 갈륨이온이 시편속에 파고들어 시편의 물질 특성이 변화되는 문제가 있지만, GFIS에서는 주로 He, Ne 와 같은 불활성 기체를 주로 사용하므로 시편과 반응을 최소화 할 수 있는 장점도 있다. 위와 같은 특징을 갖는 이온빔을 GFIS 로 생성하고 이온현미경에 사용하기 위해서는 이온빔이 팁의 단원자 내지 수 개 정도의 원자에서 생성되도록 해야 한다. 본 연구에서는 GFIS 의 원리를 소개하고 장(전계)이온현미경(Field Ion Microscope)실험을 통하여 GFIS기반으로 생성된 이온빔의 형상을 보여준다. 또한 높은 각전류밀도 구현을 위하여 질소가스 에칭으로 텅스텐 팁 끝 단원자에서만 이온빔을 생성하고, 각전류 밀도 계산과 안정도 실험결과로 본 연구에서 개발한 이온원이 이온총으로서의 이온현미경 적용 가능성에 대해 보여준다.

Great Britain and the United States and Finland are having an interest in long policy subject about child design education through early design education. And they approaches and practices it systematically. The research about the design learning program instance of advanced nation of primary school's design education for various objective is necessary for use with the fundamental reference data for an elementary design education. And so, This research presented the program instance investigation and analysis result of British primary school's design education. U.K is teaching an primary design education from two subjects of Art & Design and Design and Technology which is a legal subject with national curriculum. The analysis result of design relation unit learning program of two subjects is: Design relation unit learning programs of 'Design and Technology' subject's 20 unit which except 4 food relation unit is largely scientific engineering contents that include utility function contents in part. The reason is as behavior styles based on Design process solve problems scientifically & rationally. Design relation 6 units in subject of Art & Design which except the units which relates with the pure fine arts and architecture in 19 units is aesthetic-symbolic and utility-functional contents largely. And so, the result was analyzed about relation of scientific-engineering content of 'Arts & Design' subject is insufficient comparing with 'Design and Technology' subject Specially, I think that the design relation's unit learning program instances of 'Design and Technology' subject of the British primary school which have been presented by this research paper is a possibility becoming one reference model for a program development. And so I expects that this research could be applied in the program development for the primary design education of primary teacher & education agency.

The purpose of this study was to analyze inquiry activities in the middle school science textbooks focused on the unit 'Nutrition of Plants' of the 2007 revision curriculum and the corresponding unit 'The Structure and Function of Plants' of the 7th curriculum in terms of content, process and contexts of inquiries. The average number of the inquiry activities in the unit 'Nutrition of Plants' was 9.2, which was a 3.8 decrease than in the unit 'Structure and Function of Plants'. In the respective of process of the inquiry activities, 'observation' was most prevailing in the basic inquiry process and 'data interpretation' was most prevailing in the integrated inquiry process in both of the units. In the respective of the types and contexts of the inquiry activities, 'experiment/observation' was most prevailing and the percentage of the natural scientific contexts was larger in both of the units. In the unit 'Nutrition of Plants', the components of the integrated inquiry process and the percentage of personal contexts were larger than in the unit 'Structure and Function of Plants'. And simulation activities were newly presented and technical contexts and natural environmental contexts were included in the unit 'Nutrition of Plants'. This study makes a suggestion that a wider variety of inquiry activities should be included when new science textbooks are developed.

This study aimed at analyzing the clothing management units of technology and home economics textbooks in terms of their contents related to Education for Sustainable Development(ESD). The inquisitive tendency of the textbooks was also examined adopting the modified Romey's method, because it is known as an important factor in increasing student's class participation in sustainable clothing management and inducing practical behavior. First, the learning contents of clothing management unit were analyzed according to the social/political/cultural, environmental, and economic perspectives of ESD. As a result, ESD contents from social/political/cultural perspectives (safety, and health and food), environmental perspectives (natural resources, energy, and environmental problem), and the economic perspectives (sustainable production and consumption) were identified, with a heavy focus on environmental perspective. Secondly, Romey's inquisitive content analysis method was modified to analyze texts, pictures/charts, and learning activities of the clothing management unit. In all textbooks, facts and definitions were the dominant types of contents, which means less opportunities for development of inquiry ability. In conclusion, the ESD contents of the clothing management unit are inclined to the environmental perspective, and it is necessary that textbook development would need to be balanced between three perspectives. Also, future textbook authors will need to improve the inquisitive tendency of the textbooks to encourage student participation in class and induce practical application in real life.

연구배경: 최근 청소년 흡연의 저연령화 문제가 심화되고 있어 청소년 흡연 대책마련이 절실히 요구되고 있다. 그 중에서도 흡연예방교육은 근본적인 문제를 해결할 수 있는데, 우리나라의 교육여건상 흡연예방교육을 위하여 할애할 수 있는 시간과 독립성, 교육내용상의 질을 한꺼번에 개선하기는 매우 힘들다. 이과 같은 문제를 해결하기 위하여 본 연구는 기존의 교과 과정의 구조에 체계적인 연계성 이론을 적용하여 통합적인 흡연예방 프로그램을 구상하게 되었다. 연구방법: 수직적/수평적인 연계성 이론에서 통합성, 접합성, 연결성의 3가지 영역을 적용하기 위한 방법은 다음과 같다. 1) 지식, 태도, 기술, 행동에 따른 일반적 가이드 라인을 재조성하였다. 2) 효과적인 흡연예방을 위한 사회/심리적인 요인을 기존 교과와 같이 보완할 수 있도록 개발하였다. 3) 기존 교과서의 내용을 분석하여 흡연예방과 관련된 효과와 단원을 파악하여 2)과 3)을 접합하였다. 4) 연결성은 거시적인 관점에서 지금까지 개발된 모든 요소들이 관련되어 있음을 보여 주어야 하므로, 본 연구는 가이드라인, 강화내용, 각 교과 단원이 모두 연결되어 있음을 보여주는 표 제시로 완성하고자 하였다. 이 연구를 위하여 각 교과를 대표하는 교과서 총 111권이 검토되었다. 연구결과: 청소년 흡연예방에 효과적이라고 알려진 사회/심리적인 모든 요인들은 사회, 윤리, 도덕 등의 교과에서 충분히 다루고 있음을 알 수 있었다. 그러나, 흡연과 직접적으로 관련되어 있지 않기 때문에 흡연예방교육과 상관이 없다고 여겨질 수 있다. 이러한 단점을 보완하기 위하여 각 관련 교과와 단원, 흡연예방관련지도를 제안하는 교사용 보완 지도자료 지침서가 개발되었다. 흡연예방교육에 필요한 모든 교육적인 요소들이 수직적(초중고등학교), 수평적(각 교과간)으로 연계되어 있음을 보여 주었다. 연구결론: 독립적인 흡연예방 프로그램을 개발하기 보다는 이와 같이 기존의 커리큘럼에 구조적으로 통합할 수 있는 흡연예방 프로그램이 비용-효율적일 수 있다.
