Recently there are many researches of text mining to find interesting patterns or association rules from mass textual documents. However, the words extracted from informal documents are tend to be irregular and there are too many general words, so if we use pre-exist method, we would have difficulty in retrieving knowledge information effectively. In this paper, we propose a new feature extraction method to classify mass documents using association rule based on unsupervised learning technique. In experiment, we show the efficiency of suggested method by extracting features and classifying of documents.

Basic science teaching and clinical education should be integrated whenever appropriate, and the development of skills, values, and attitudes which are emphasized to the same extent as the acquisition of knowledge in nursing. Problem-based learning provides a students-centered learning environment and encourages an inquisitive style of learning. The purpose of this paper is to review and comment the role of tutors and students on problem-based learning. The use of problem-based learning places a high demand on faculty members' time and support. The role of tutors in Problem-based learning focuses primarily on issues of developing and teaching the curriculum and on organizational implementation and institutionalization. Tutors are an integral part of course planning. Tutors serve as a constant source of feedback on student needs and concerns to the course director and constitute an informal steering committee while the course is in progress. Tutors write cases, develop student evaluation methods, recommend resources, suggest modifications in lectures and laboratories. Students have a limited amount of time available to study what is traditionally defined as the core content of nursing. But, the role of students in Problem-based learning would be active, independent learners and problem-solvers rather than passive recipients of information. Students using a deep level approach attempt to integrate what they learn with what they already know, to understand the meaning underlying the material to be learned, and to look for explanations rather than facts. Students are encouraged, with appropriate guidance, to define their own learning goals, to select appropriate experiences to achieve these goals, and to be responsible for assessing their own learning progress. Problem-based learning is more flexible and meaningful, by encouraging student interaction, and by having a better emotional climate than the conventional learning.

Science festivals have occupied a very important axle in informal science education that enables students to experience the amazement of scientific experiments to think over scientific principals beyond the formal education in the classrooms. Among the concerned person, the most benefit-taken group may be the assistant who help the participants experience the activities in the festival. In order to find out the ways to make the student assistant's participation into a meaningful education experience, we analyzed the types of the activities in the science festival as well as the characteristics of the interaction between the student-assistants and the participating students are studied. The research findings are as follows: First, most activities in the science festival had related to the scientific concepts or principals; however, the understanding of the concepts and principals didn't highly affect the procedure of the activities. In many cases the students operated and made results without checking the related concepts or principals. Second, the student-assistants showed the consistency of operation in guiding their activities. They were explaining mainly the process of the experiments without giving a chance to think of related concepts or principles. We suggest that teacher should consider the student-assistants' learning in the festival as well as that of the participants.

The purpose of this study was to explore what kinds of science communication are ongoing in formal and informal settings for learning about nuclear energy, which is very important issue domestically and internationally. The researchers collected and analyzed data from science textbooks at elementary and middle school levels, from exhibitions in Y informal hall that belongs to one nuclear power plant, and from 40 bestselling books about nuclear energy in order to explore the kind of science communication. The same process was used to explore Japanese case so that we could compare the results with Korean cases and draw implications for enhancing science communication about nuclear energy. The science communication of nuclear energy in Korea included implicit and indirect content espoused in science textbooks; two opposite views displayed in bestselling books, and positive aspects mainly displayed in exhibition of information hall in nuclear power plant. It is suggested that both direct and explicit science communication along with the neutral viewpoints including positive and negative ones be provided for the public to form a good understanding of nuclear energy.

오일러 공식과 오일러 표수는 다면체를 탐구하는 지표의 역할을 하기 때문에 위상적 불변량이라는 관점에서 중요한 수학적 개념이다. 우리나라는 3차부터 7차 교육과정까지 오일러 공식에 관한 내용이 교과서에 언급되었으나 이후 교육과정에서 제외되었다. 본 연구에서는 영재교육이나 방과후교실과 같은 비형식적(informal)교육과정의 소재로 오일러 공식과 오일러 표수에 주목하였다. 본 연구에서는 먼저 오일러 공식과 오일러 표수가 가지는 의미를 수학사와 그 응용분야, 교육과정에서 찾아본다. 이를 위해 오일러 공식과 오일러 표수의 역사, 다양한 수학 분야에 기여한 내용, 그리고 교육과정에 도입된 오일러 공식에 관한 내용을 살펴본다. 나아가 공식 암기가 아닌 탐구 활동의 대상으로 오일러 공식을 새롭게 조명할 수 있는 학습 환경을 제안하고 이를 이용한 활동을 예를 들어 살펴본다.

The $4^{th}$ industrial revolution refers to an era where machines capable of outperforming humans are created. In light of the 4th industrial revolution, university students are demanded problem solving abilities, critical thinking abilities, and problem discovering abilities as general and basic abilities. The need for changes in the university level communication education for engineering students remains imperative in this constantly changing social environment. The era where education is conducted only in classrooms is over. This paper discusses the need for diversified education such as the integration of online and offline education, the reinforcement of learning outside of the classroom as well as an education model that transcends formal and informal education such as games and activities that induce self-learning, both intentional and non-intentional learning, and the utilization of mass media and social networking systems. Through providing an education model that assesses and utilizes the data gained from the learning process provided above, this paper widens the perception of future education methods in the 4th industrial revolution.

최근 연구에 따르면 학생들의 진로 선택에서 비정규학습이 정규학습 못지않게 영향을 주고 있는 것으로 나타났다. 다양한 형태의 비정규 과학교육 활동이 시행되고 있는 가운데, 2004년 국내에서는 한국공학 한림원을 중심으로 기업의 공학 기술인이 학교 현장에 찾아가 학생들과 함께 과학 실험, 공작 활동을 하는 것이 새롭게 시도되었다. 이러한 '주니어 공학기술 교실' 사업은 한국공학한림원에서 과학기술자에 대한 올바른 인식과 첨단 과학기술에 대한 이해 증진을 위해 민간주도로 지역의 과학기술자가 초${\cdot}$중등 학교를 직접 방문하여 과학기술 교육을 지원하는 형식으로 시행되고 있다. 2004년 현재 대기업과 중소기업 17개 기업이 참여하고 있다. 주니어 공학기술교실에서는 공학 기술인이 학생을 가르치는 교사(이하 기업 교사)로, 현직 교사는 기업 교사와 학교 현장을 중계하는 매개자 역할을 하게 된다. 새롭게 시도되는 비정규 과학 활동이라는 점에서 이 프로그램의 직접적인 운영자인 기업 교사와 이를 바라보는 학교 현직 교사의 인식은 매우 중요하다. 본 연구에서는 비정규 학습에 대한 현직 교사와 기업 교사의 인식을 조사함으로써, 기업 교사가 학교 현장에 참여하는 비정규 과학교육 활동에 대한 시사점을 알아보고자 하였다. 설문과 현장 수업 참관을 통해 조사한 결과, 기업 교사와 현장 교사 모두 본 사업의 취지에 공감하였으며, 사업의 시행 결과에 매우 만족한 것으로 나타났다. 하지만 일부 기업 교사는 교재와 교구, 학교와 기업의 협조 분위기에 불만족을 나타내기도 하였다. 또한 현장 교사와 기업 교사 모두 프로그램의 적절성이 주니어 공학기술 교실과 길은 비정규 과학교육 사업의 성공과 실패를 좌우한다고 생각하였다. '주니어 공학기술 교실'과 같은 비정규 과학교육 활동이 효과적으로 시행되고 사회적으로 확산되기 위해서는 적절한 프로그램의 개발 노력이 무엇보다 중요하며, 학교와 현직 교사 등 교육계의 적극적인 수용 및 활용 의지가 더욱 필요한 것으로 보인다.

In allowing visitors to manipulate objects or models with their hands, science museums can become informal education institutions. However, little research has been conducted analyzing the specific interactions of visitors at museums and the effects that specific characteristics of interactive exhibit have on visitors. This research classified exhibits according to the three characteristics: the presentation of concepts, interaction with exhibits and concept levels. Further, relationships among engagement behaviors, visitors'attraction to exhibits, and the holding power of exhibits were analyzed. Using the three characteristics, 55 exhibits were classified into five styles. The results suggest that intriguing content and novel interfaces, maximizing information on science and technology, should be developed for the educational purpose of encouraging visitors to engage in active learning with interactive exhibits. The results of this study provide useful data that planners, designers, and instructors of science museums can use to maximize visitors' participatory learning and interactions.

This paper is a qualitative study of the experiences of Korean heritage language learners (KHLLs) with literacy (reading and writing), particularly before they enter the college-level heritage language classroom. Previous research, both qualitative and quantitative, has addressed the overall language background of KHLLs, including oral and aural proficiency and writing and reading ability, as well as demographic information (such as when the student immigrated to the United States) in relation to language test scores. This study addresses KHLL experiences in the following six areas as they relate to student perceptions and attitudes toward their own heritage language literacy: language proficiency, motivation for learning, academic preparedness, cultural connectedness, emotional factors, and social factors. Fourteen undergraduate students at a university in the western United States participated in a convenience sample by responding to a 10-question survey. Trends in responses indicated that KHLLs entered the classroom with high integrational motivation and experienced great satisfaction with perceived progress in literacy, but students also expressed regret for having missed childhood learning experiences that would likely have resulted in higher proficiency. These experiences include informal and formal instruction in the home and formal instruction outside of the home.
