The purpose of this study was to explore the possibility of mathematical instruction through performance task activities based on the The Backward Design, which was suggested at first by Wiggins & McTighe in 1998. The Design deals with a performance assessment task involving the whole objective and its entire content of a lesson. Based on the Backward Design, this study established the mathematical instructional materials, which deal with the concept of 'the sector' taught in middle school, with one large performance task including three small tasks. It is important that in the lesson students be guided to achieve the several learning goals by themselves through reasoning activities. For this purpose, a formal interview was carried out by the subject of three middle school mathematics teachers. As a result, in order to implement the instruction utilizing the performance tasks more efficiently in future, it is required that a large performance task should be selected or developed including the content or problem contexts to be relevant with the real-life challenging situations. In addition, to make students enhance reasoning skills, it is strongly requested that the tasks including the utilization of supplementary materials such as technological devices or manipulatives be dealt with in a lesson.

새로운 밀레니엄을 불과 몇 년 앞둔 지금 우리는 정치.경제.사회.문화.과학기술 등 전 분야에 걸쳐 전개되고 있는 역동적인 변화를 몸소 체험하고 있다. 냉전시대의 종식 이후 세계의 정치 구도는 경제패권을 둘러싼 지역화.블럭화의 경향을 보여주고, 플랜트와 하드웨어 중심의 규모의 경제가 기술중심의 소규모화 된 현장중심의 범인의 경제로 전환되는 와중에 있다. 사회.문화적 측면에도 오늘날 우리는 국제화, 다원화, 지방화의 무드 속에서 조직구조의 변화는 물론 이에 따른 인간의 가치관과 생활양식의 변화를 때로는 능동적으로 혹은 피동적으로 체험하고 있다. 한편, 과학 기술 분야의 변화는 거대 에너지와 물자를 활용하는 ‘힘-중심적’ 방향에서 새 사고와 아이디어를 요구하는 ‘지식-중심적’ 방향으로 옮겨가고 있다는 것이다. 이는 과학과 기술에 있어서도 에너지, 재료, 기계 등 대대적으로 활용하는 거시적 과학과 기술로부터 지식, 정보, 통신을 중심에 두는 정밀과학, 정밀기술 쪽으로의 변화가 진행중이라는 것을 의미한다. 사회의 변화와 관련된 교육적 대응의 원리는 두 가지 형태로 집약될 수 있다. 교육은 본질적으로 순응(accommodation)과 적응(adaptation)이라는 서로 상반되는 두 가지 기능을 수행한다. 순응의 원리는 교육의 탄생이래 교육목적의 본질에 해당되는 것으로 기존 사회질서의 유지와 체제 존속을 위해 교육은 과거로부터 전해져 내려오는 의미 있는 문화내용을 엄선하여 미성숙한 학생들에게 전수하고 그들로 하여금 문화와 전통을 계승하도록 하는 사회화에 그 일차적인 목적이 있다는 것이다. 따라서 순응의 원리를 강조하는 교육은 과거 지향적이며 외부의 변화에 대해 수동적인 자세를 견지한다. 한편, 적응의 원리에 입각한 교육은 문화와 전통에 대한 피동적 전승을 넘어서 사회의 변화에 따라 교육체제와 내용을 바꾸는 등 적극적으로 변화에 대응하고, 이러한 변화를 주도할 인간육성에 힘을 기울이는 교육방식을 취한다. 시대적 변화의 소용돌이 속에서 교육은 이제 기왕의 많은 교육적 신화들을 타파하고 뉴 밀레니엄을 준비해야할 기로에 서 있다. 현재의 변화를 슬기롭게 대처하고 미래의 변화에 능동적으로 적응하는 인간을 육성하기 위한 오늘날 교육의 사명은 우선 미래사회를 위한 교육정책의 방향을 수립하는 일이다. 교육정책은 국가의 교육방침으로서 현실 교육문제의 해결도 중요하지만 미래의 발전을 기약할 수 있는 장기적인 비젼과 목표 속에서 정립될 필요가 있다. 이러한 의도하에 본 연구는 21세기를 대비한 교육정책의 방향을 탐색하고 그에 따른 정책적 과제를 제시하는 데 그 목적이 있다. 이러한 목적하에 본고는 \circled1 과거 우리 나라의 교육정책을 반성적으로 회고하고, \circled2 미래사회에 대한 전망과 교육적 시사점을 분석하며, \circled3 마지막으로 21세기의 변화에 적응하기 위한 교육정책의 방향과 과제를 내용으로 제시하고자 한다.

Conventionally, scientific data visualization is thought of as one of activities performed by scientists during the scientific data analysis. However, recently, there exits a set of research papers which count scientific data visualization as a independent research area. They show the research subjects for studying the scientific data visualization technology and methods. In case, a scientist or group of scientists can not solve their own visualization problem due to the unskillfulness and inexperience on using visualization tool. Therefore, it needs to help them by the systematic way for solving the problem. In this study, we analyze and propose the national level scientific visualization support system for scientists. In particular, we first analyze the existing papers and find out the critical success factors. Then, by integrating the findings of the analysis, we propose the research areas which need to be focused, and the strategic direction and specific research topics for scientific data visualization support system in national level.

This paper investigates conditions, issues, and themes in the social responsibility of scientists and engineers by the examination of various materials in science and technology studies(STS). Firstly, the institutionalization of science and technology in society works as a objective conditions for the responsibility of scientists and engineers. Secondly, discussion on scientists and engineers as professionals should be complemented by focusing on the public character of science and technology. Thirdly, various social relevant groups should be comprehensively considered in the ethical conflicts of scientists and engineers. Finally, this paper suggests some themes in science and engineering ethics to strengthen the social responsibility of scientists and engineers.

The purpose of this study was to review the government's policy on the enhancement of sports facilities for community residents regarding the lack of knowledge surrounding the infrastructure of sports facilities. The government has invested approximately 2.4 trillion won to establish 220 community sports centers, 385 billion won for 194 multi-purpose indoor centers, and 1.3 trillion won for rebuilding 1,870 school outdoor fields. On the other hand, there are problems with the link between the crumb rubber infill on sports fields and cancer, a lack of availability of indoor sports centers, and an increased federal budget deficit. It is the responsibility of government to plan and construct outdoor fields that are large enough to accommodate all people and allow them to play activities. In addition, the guidelines should ensure that the indoor space required for physical activities at each teaching station is large enough to accommodate all students in the class and handle two classes. The government should suggest the federal government guidelines based on a good understanding of the concept of infrastructure in sports facilities. The government also should make efforts to reduce the regulatory powers and provide the community with an autonomous right to plan and construct sports facilities.

Considering the high density developments along the major traffic corridors in Seoul, transit-oriented street designs will be a very effective to control traffic congestion along the corridors. For testing the effectiveness, we selected. for our case study, Kangnam Street, which is one of the most highly developed corridors in Seoul The traffic study on Kangnam street in 2000 shows that the daily average bus speed is 11.73km/h, which is 5km/h lower than the auto speed. The Central Bus Lane system was applied on the Kangnam street to test impact on bus speed as well as auto speed. Simulation results show that with Central Bus Lane have been improved the travel speeds of bus as well as auto on Kangnam street from 14.4km/hr to 35.0km/hr and from 25.1km/hr to 26.1km/hr, respectively. The bus market share increases about 6-8 percentages. Especially, 13.4% of bus users are increased for long-distance trips.

This study aims to propose a scaffolding strategy that can be applied to the information search process by using Kuhlthau's ISP model, which presented a design and implementation strategy for the mediation role in the learning process. To this end, the relevant literature was reviewed to categorize scaffolding strategies, and impressions were collected from the students surveys after providing 150 middle school students in the Daejeon area with the project class to which the scaffolding strategy based on the ISP model was applied. The collected data were processed into a form suitable for analysis through data preprocessing for word frequencies to be extracted, and topic analysis was performed using STM (Structural Topic Modeling). First, after determining the optimal number of topics and extracting topics for each stage of the ISP model, the extracted topics were classified into three types: cognitive domain-macro perspective, cognitive domain-micro perspective, and emotional domain perspective. In this process, we focused on cognitive verbs and emotional verbs among words extracted through text mining, and presented a scaffolding strategy model related to each topic by reviewing representative document cases. Based on the results of this study, if an appropriate scaffolding strategy is provided at the ISP model stage, a positive effect on learners' self-directed task solving can be expected.

The purpose of this study is to examine the research trends regarding the published articles in the Journal of Korean Gerongological Society within the past 10 years. This study is based on the article written by Won and Mo (2008). This article classified previously published studies into themes, methods, and application of theory. Out of the total of 187 articles published in the past 10 years, 11 articles were about social change and institution, 94 articles were about social issues, 12 articles were about social problems and deviation, 42 articles were about social culture, 14 papers were about gerontological theory and 13 papers were about residence/architecture. In the last 10 years, the most popular topic was around the various ways aging. New topic that emerged was the effect of IT and technology on the quality of life among the older adults. Other topics that gained interest were age discrimination and prejudice on aging. Trends in research methods showed increased use of qualitative methods. In the future, more research needs to be completed to theorize the results of quantitative research. Furthermore, the use of qualitative research methods needs to be increased in order to understand the lives of older adults in depth. Through more meta analysis, the results of past research articles should be synthesized to get a bigger picture of the Korean older adults.
