타당하고 효과적인 과학교육의 계획과 실천을 위해서는 축적된 연구 결과에 근거한 과학교육 정책의 결정이나 교육과정 개발, 교수학습 방법 및 적절한 학습 자료 개발 등이 이뤄져야 할 것이다. 그러나 실제로는 그러하지 못한 실정이다. 이에 본 연구에서는 2000년부터 2013년까지 국내 주요 과학교육 관련 학회지에 게재된 논문들을 대상으로, 근래 학생의 과학 학습과 관련된 국내 과학교육 관련 연구의 전반적인 동향을 분석함으로써, 추후 과학 교육과정 개발이나 정책 개발, 교수학습자료 개발 등에 기초자료와 시사점을 제공하고자 하였다. 이를 위해, 국내 6개 주요 과학교육 관련 학회지에 2000년도부터 2013년도까지 게재된 과학 학습 관련 논문을 분석하였다. 분석은 총 8개의 과학 학습영역('학생의 개념', '학생의 사고', '탐구', '정의적 영역', '학생의 과학에 대한 생각', '교육과정', '학생의 학습/수업활동', '비형식 교육에서 학생의 학습')과 각 영역의 세부 범주에 의거하여 수행되었다. 분석결과, 기존의 연구들은 다소 특정 분야와 특정 대상에 편중되어 있었다. 또, 발달 과정보다는 현재 실태를 진단하는 연구들이 많았다. 새로운 이론이나 도구를 개발하는 연구들이 상대적으로 적었고, 다소 직접적이진 않지만 학생의 미래에 영향을 미칠 수 있는 과학의 본성에 대한 인식이나 비형식 학습에 대한 연구 역시 상대적으로 적었다. 이러한 연구 결과들을 바탕으로 교육과정 개발이나 정책 개발, 교수학습자료 개발 등과 관련된 몇 가지 시사점에 대해 논의 하였다.

This study was undertaken to analyze the research trends on science education in Korea. In this study the analysis for of trends of researches on science education, nine areas such as historical change of science Education, Processes of science learning science curriculum, science instruction, teaching-learning materials and equipment for science education, valuation on science education, survey on Korean science education, policy and management of science education, and natural science, were chosen for the analysir. All science education. thesis and dissertations in Korea, papers of science education published by the science center of the Seoul National University and the papers of the Journal of the Korean Association of Res Search in science Education were analyzed. The findings of this study are as follows: 1. Seventy percentile of science educational thesis and dissertations are on natural science areas. 2. About 14% of all papers being sampled is in science curriculum research category. There are few research studies on historical changes of science education, and teaching-learning materials and equipments for science education.

강화학습의 기본적인 알고리즘으로 많이 사용되고 있는 Q-Learning은 현재 상태에서 취할 수 있는 행동의 보상 중 가장 큰 값을 선택하는 Greedy action을 통해 보상을 최대화하는 방향으로 에이전트를 학습시키는 기법이다. 본 논문에서는 Frozen Lake 8*8 그리드 환경에서 Q-Learning을 사용하여 에이전트의 학습 속도를 높일 수 있는 정책에 관하여 연구하였다. 또한, Q-learning 의 기존 알고리즘과 에이전트의 행동에 '방향성'이라는 속성을 부여한 알고리즘의 학습 결과 비교를 진행하였다. 결과적으로, 본 논문에서 제안한 Q-Learning 정책이 통상적인 알고리즘보다 정확도와 학습 속도 모두 크게 높일 수 있는 것을 분석되었다.

The survey is intended to improve science education by the analysis of problems produced in the following nine aspects (objectives, contents, materials, inquring methods, teaching methods, teachers, children, evalutions, admininative supports) during the past five years often the revision of new science curriculum. 1. View for science education. 1) The teacher's and children's view for science education can be seen renewed, being different from the old one. 2) Inquring method in learning and teaching began to take firm root and children came to know that it is the only way to study science. 3) Writers think that the new science education has stepped into the stage of being fixed to a considerable degree. 2. The aspect of administrative policy. 1) The amount of materials in possession is small and the present materials are lacking in solidity and precision. 2) Class room teacher's over load with miscellaneous things is a difficult problem to solve. 3) The shortage of the printed materials and books for children and teachers has an influence on the development of inquring method. 4) It causes cramming to examine all children at the same time by paper test. 5) It is more desirable to appoint qualified teacher only for science teaching. 3. Contents of science curriculum. 1) In current science textbooks. There can be found some contents which are difficult for teachers to understand and not in accordance with the reality of Korea. Therefore, it is imperative that contents of science textbooks should be reexamined. 2) As it is hard to teach concepts of reciprocal action and to prepare materials with teaching of the system of biological concepts, the teaching of contents is likely to be a cramming. 4. The aspect of in-service education. 1) It is obsolutely predominant reation that in-service education is making a great contribution to class room teaching. 2) As adiministrators' policy for science education has a great effect, in-service education for their enlightenment is needed.

강화학습의 기법 중 Q-Learning은 주어진 상태에서 행동을 수행하면서 미래의 효율적인 기댓값을 예측하는 Q 함수를 학습하면서 최적의 정책을 학습하는 것이다. Q-Learning은 강화학습의 기본적인 알고리즘으로 많이 활용하고 있다. 본 논문에서는 Q-Learning을 바탕으로 정책과 보상을 설계하여 효율적인 경로를 선택하고 학습하는 효용성에 대하여 연구하였다. 또한 Frozen Lake 게임의 8x8 그리드 환경에 동일한 학습 횟수를 적용하여 기존 알고리즘 및 처벌 보상 정책과 제시한 처벌강화 정책의 결과를 비교하였다. 해당 비교를 통해 본 논문에서 제시한 Q-Learning의 처벌강화 정책이 통상적인 알고리즘의 적용보다 학습 속도를 상당히 높일 수 있는 것으로 분석되었다.

Fabrication, falsification, plagiarism (so-called FFP), and other unethical acts damage the trust of public in science and scientists. Scientific communities, governments and research institutions should take the appropriate countermeasures. With the increasing visibility and importance of problem, funding agencies and policy-makers find that they must have a better understanding of this phenomenon, and take steps to prevent it. Science is often said as a borderless activity. In these days, many scientific misconduct cases have been emerging almost simultaneously and worldwide. Thus, the immediate actions should be taken internationally as well as nationally. From these points of view, we, Japan, proposed a new international joint-study at OECD Global Science Forum in February 2006, and the proposal was approved with supports by many countries including Korea. OECD would seek an international perspective to address this worldwide problem, bringing together the representatives of science communities, publishers, funding agencies, and policy makers, and exchanging their experiences.

This paper presents the policies Korea adopted to educate and train scientists/researchers and technicians/skilled workers. The Korean policies for the increase of human resources in science and technology that stimulated an upgrading of skills in industry and adapted to technical advancements are identified. An important factor is that the supply and demand mechanism created a virtuous circle so that the science and technology education and training policies were responsive to economic demands. In addition, policies to foster a human resource capacity have enhanced the contribution of human resources in science and technology for innovation and economic growth.

It is recent that STEM (Science, Technology, Engineering and Mathematics) education emerged as a great concern of the U.S. policy makers in terms of securing national and regional competitiveness. However, few attempts to embrace STEM education as a source for sustainable regional growth have been made mainly due to methodological challenges. This paper investigates the role of STEM education in achieving sustainable economic growth. For the purpose of the paper, a U.S. federal workforce development program named Workforce Innovation in Regional Economic Development (WIRED) in Southeastern Virginia that was implemented between 2007 and 2010 is selected and evaluated qualitatively. By identifying three themes as a result of three-stage coding methods, the evaluation results call for particular attention of local policy makers and key stakeholders to STEM education as a source of sustainable long-term economic growth in regions.
