본 논문은 연구개발과 이공계 고등교육의 상호 연계를 통한 시너지 극대화를 위한 사이버 인프라스트럭처에 기반한 차세대 연구 교육 융합환경의 구축방안을 제시하고자 수행되었다. 국가 R&D 사업을 통하여 생성 및 축적된 연구결과를 이공계 대학 및 대학원의 교육 현장에 직접 연계시킬 수 있는 방안을 마련하고자 하였다. 먼저 사이버인프라 기반의 연구개발 패러다임의 변화를 검토하였다. 이어서 연구성과를 교육에 활용하여 연구과 교육의 융합을 도모한 모형과 사례들을 분석하였다. 이러한 선행연구를 바탕으로 해서 우리나라 실정에 적합한 연구 교육 융합환경 시스템을 제안하였고, e-AIRS의 사례를 들어서 구체적으로 설명하였다. 마지막으로 이러한 사업을 추진하기 위한 정책적 과제들을 논의하였다.

우리 사회의 소중한 자산이 될 다문화 학생들을 위한 과학 교육적 배려를 제공하기 위한 목적으로 본 연구가 기획되었다. 다문화 학생들이 생각하고 있는 과학 학습을 파악하여 그들의 상황을 이해하고 과학 교육 차원에서 배려하고 지원하는 방향을 고민함으로써 그들을 고려한 과학 교육계의 관심을 불러일으키고자 한다. 이를 위해 다문화 가정 초등 및 중등 학생과 학부모, 그리고 다문화 학생들을 가르치고 있는 초등 교사 및 중등 과학 교사들을 대상으로 집단 면담을 실시했다. 면담을 통해 다문화 학생들의 과학 교육에 있어서 무엇보다도 언어적 지원이 필요하다는 점을 발견했다. 이 밖에도 다문화 학생들을 바라보는 교사와 친구들의 기대치가 낮다는 점도 알았다. 우리 상황에 맞는 다문화 과학 교육의 내용과 방법, 그리고 학교 차원의 제도적 지원을 통해 모든 사람을 위한 과학적 소양을 실천해야 할 것이다.

The national reform document, Science for All Americans (AAAS, 1990), and the Next Generation Science Standards (NRC, 2012) emphasize the importance of the nature of science in guiding science educators in accurately portraying science to students. Therefore, it is important that textbook materials convey an accurate conception of the nature of science. This study employs content analysis to examine the content of textbooks in US and Korea elementary science textbooks with regard to the four aspects of the nature of science: (a) nature of scientific knowledge; (b) nature of scientific inquiry; (c) nature of scientific thinking; and (d) nature of interactions among science, technology, and society (Chiappetta, Fillman, & Sethna, 2004). Intercoder reliability was determined by calculating Cohen's kappa (Cohen, 1960). Findings show that while US elementary science textbooks are not balanced in presenting the four aspects of the nature of science regardless of the publishing companies, the presentation of the nature of science in Korean elementary science textbooks have better balanced treatment of the four themes across the grade levels. On the other hand, both US and Korean elementary science textbooks are attempting to convey an idea of what science is by emphasizing scientific knowledge and investigation.

What is the "new paradigm"? It is impossible express it in one or two words, but if one had to; the closest might be the "holistic approach". The expression can be justified by the fact that the conclusions above lead to a greater intermixing of mathematics with engineering and natural sciences subjects, typically expressed in the form of examples of simplified real problems. They also lead to a greater intermixing of subjects within mathematics so that the courses should have less separation e.g. between symbolic and numerical mathematics. The conclusions also lead to the spreading the mathematics courses throughout all study years, not just the first two years. Of course, this should be done with great care in order to guarantee studies that are logically linked together. The new paradigm also means that the needs arising from industrial mathematics must be taken into account in the contents of engineering mathematics courses. Such topics are e.g. multivariate methods, statistics and use of mathematical software. What are we expected to gain from the paradigm shift? The primary benefit should be in obtaining more productive engineers equipped with a better degree of mathematical preparedness for engineering problems. But in addition, it should also promote more intensive use of applied mathematics and easier communication with professional mathematicians, often needed in complicated industrial problems.?Finally, it can be noted that the new paradigm is in harmony with the basic ideas of the CDIO (Conceive - Design - Implement - Operate) initiative for producing the next generation of engineers [1]. New ideas for engineering education can be found also in the homepage of SEFI (European Society for Engineering Education) [2].

In the paper, the actual situation of Korean organic agriculture and its development history regards to basic skills of organic farming were reported. And an education for organic farming in the universities with schools of agriculture in European countries was also reported to deliver the information on the course of organic agriculture for Korean Universities facing the problem which have a lower admission competition than previous Year. The examination for organic engineer certificate which was introduced in 2001 and the proposed government research institute, so called "Research Center of Organic Agriculture" were also shortly discussed. In the conclusion, \circled1 the establishment of "research Center of Organic Agriculture" which should by attached RDA for the systematic approach of research for organic agriculture and the test of agricultural materials using for organic farming, \circled2 department of organic agriculture in the Universities with schools of agriculture to offer next generation an opportunity to learn an organic farming parallel to conventional farming, \circled3certification body system by third party, and \circled4 full support by Korean government and scientist society for "Asian Research Network of Organic Agriculture (ARNOA)" headquartered in Korea as international research organization were strongly suggested.

Research and national standards, such as the Next Generation Science Standards (NGSS) in the United States, promote the development and implementation of K-12 interdisciplinary curricula integrating the disciplines of science, technology, engineering, mathematics, and computer science (STEM+CS). However, little research has explored how teachers provide epistemic support in interdisciplinary contexts or the factors that inform teachers' epistemic support in STEM+CS activities. The goal of this paper is to articulate how interdisciplinary instruction complicates epistemic knowledge and resources needed for teachers' instructional decision-making. Toward these ends, this paper builds upon existing models of teachers' instructional decision-making in individual STEM+CS disciplines to highlight specific challenges and opportunities of interdisciplinary approaches on classroom epistemic supports. First, we offer considerations as to how teachers can provide epistemic support for students to engage in disciplinary practices across mathematics, science, engineering, and computer science. We then support these considerations using examples from our studies in elementary classrooms using integrated STEM+CS curriculum materials. We focus on an elementary school context, as elementary teachers necessarily integrate disciplines as part of their teaching practice when enacting NGSS-aligned curricula. Further, we argue that as STEM+CS interdisciplinary curricula in the form of NGSS-aligned, project-based units become more prevalent in elementary settings, careful attention and support needs to be given to help teachers not only engage their students in disciplinary practices across STEM+CS disciplines, but also to understand why and how these disciplinary practices should be used. Implications include recommendations for the design of professional learning experiences and curriculum materials.

본 연구에서는 가리맛조개(S. constricta)의 토사물을 현미경 검경과 차세대염기서열분석(NGS) 기법으로 먹이원을 확인하고, 이를 통해 형태학적 및 분자학적 방법에 따른 먹이원 분석을 비교하였다. 가리맛조개(S. constricta)의 먹이원은 분석방법에 따라 차이를 보였다. 먹이원생물은 위 내에서 분해되어 현미경 분석을 통한 생활사 확인과 정량적 분석이 가능하였으나 형태학적 및 해부학적 특성 파악이 불완전하였다. NGS 분석은 유기물 형태로 잔존하는 생물의 DNA 확인이 가능하여 현미경 검경 결과와의 상호보완적 적용 가능성을 확인하였다.

Augmented reality is a technique for combining virtual images into real life by showing information of virtual 3D objects on top of a real-world environment (Azuma et al., 2001). This study is an augmented reality-based educational content delivery device that receives user input that selects either a preset object or a photographed object for augmented reality-based training; It includes a three-dimensional design generation unit that generates a stereoscopic model of the augmented reality environment from an object, a three-dimensional view of the scene, a disassembly process of the developing road from a three-dimensional model, and a content control unit provided by the user terminal by generating educational content including a three-dimensional model, a scene chart, a scene, a decomposition process, and a coupling process to build a coupling process from the scene to the three-dimensional model in an augmented reality environment. The next study provides a variety of educational content so that children can use AR technology as well as shapes to improve learning effectiveness. We also believe that studies are needed to quantitatively measure the efficacy of which educational content is more effective when utilizing AR technology.
