Problem Based Learning (PBL) is one of methods which has been developed to promote student-centered learning and to pursue self-directed learning for life-long learning. The purpose of this study is exploring the possibility of Problem Based Learning (PBL) in college Earth science course. The participants of this study were fourteen students attending an Earth science class at Sookmyung Women's University in Seoul. PBL was implemented in the form of group project with utilizing Web-based course tool. We provided questionnaires and conducted interviews to figure out students' perception about PBL. The findings were as follows: Through a given experiences, (1) students participated more actively than LBL (Lecture Based Learning), (2) more students were engaged with self-directed learning, and (3) students made higher cognitive efforts. LBL seemed to be more efficient way to acquire factual knowledge. In the meanwhile, PBL did not seem to affect the improvement of communication skills. Students could not make use of Web-based course tool effectively in communicating with other team members. In this study, we found that college student participants preferred problems related to everyday life, environmental issues and interesting but unusual incidents. On the other hand, they felt difficult in open-ended problems, especially when they were asked to provide their own evaluation. On the basis of PBL experiment in this paper, we present one method of successful implementation of PBL and suggest topics which should be studied in the future.

본 연구는 지역사회 환경문제에 관한 토론 수업이 고등학생들의 환경 인식, 환경 문제에 대한 의견과 그 판단근거, 환경 문제 해결방안에 미치는 영향을 알아보는 연구이다. 본 연구에서 개발된 토론 수업은 도심 내의 백로 서식지 문제를 주제로 3차시에 걸쳐 지역사회 환경문제에 대해 알아보고, 토론하는 수업이다. 연구의 주요 데이터로 수업 전후 환경 인식 검사지, 환경 인식 설문지, 학습지가 수집되었다. 환경인식 검사지는 Likert 척도로 기술적 통계로 분석되었으며, 환경 인식 설문지의 응답은 귀납적 질적연구 방법을 통해 분석되었다. 본 연구의 결과는 먼저 환경 인식 검사지의 환경 인식에서 사전-사후 유의미한 통계적 효과가 있었다. 다음으로 SSI 토론 주제인 "백로의 서식지를 이동해야 하는가?"에 대하여 과반수의 학생들이 찬성하였으며, 토론 수업이후에도 의견에 변화가 없었다. 하지만 토론 수업 이후 학생들의 해경방안은 단기적이고 실현 가능하며, 구체적이고 비용이 적게 드는 해결방안으로 바뀌었다. 본 연구 결과를 바탕으로 학생들의 지역환경문제에 대한 관심을 높이고 문제해결력 증가를 위해 학교 과학 수업에서 지역 환경 문제와 관련된 SSI 토론 수업의 필요성을 제언한다.

This paper was built for an activation of a merged education and development of non-subject, new type creative merged education program having effectivities. This program is disciplined a kind of flipped learning and camp program of 2 nights and 3 days. Given a problem which big enough and open-ended problem, multidisciplinary team that composed with engineering and design major students works the capstone design project. For ordinary engineering design process, 'how can we make?' was important. But in this program 'what can we make?' is more serious question. Our program was pursuing an creative idea that can induce innovation. Teaching or interference of professors was minimized and then students solve the problem theirselves by long time and liberal brainstorming. Last products is not real goods and only a proposal for manufacturing. Finally, the results are presented using ppt and board. After not only professors but also students of other teams can ask a question, resolve and comment on that proposal. The benefits of this program are that inner members of university take a whole process from planning and working to last evaluation. Besides economic benefit, they can secure an infrastructure for development of creative merged education program by running for several times and so can improve the program continuously. For an aspect of students, they can respond to recently highlighted creative experiences that required for recruitment.

Action learning motivates students to solve open-ended problems by 'developing skills through doing'. This paper reviews the concept of action learning and discusses the adoption of action learning approach to teach operations management at universities. It presents the design and delivery of an action-learning course at City University of Hong Kong. The course incorporates classroom lectures, tutorials and an action-learning workshop. The experience gained proves that action learning facilitates student participation and teamwork and provides a venue of accelerating learning where enables students to handle dynamic problem situations more effectively. The paper concludes that adopting action-learning approach can help lecturers to enhance quality teaching in operations management courses, and provide an alternate means of effective paradigm other than traditional classroom teaching and/or computer-based training at universities.

초등학교에서 교사는 그들이 가르쳐야 하는 수학에 관한 지식 뿐 아니라 그들의 학생들이 미래에 배워야하는 수학에 관한 지식도 풍부하여야 한다. 초등수학의 수와 연산 영역 중에서 초등학교 학생들이 매우 어려워하는 개념 중 하나가 나눗셈 개념이다. 이에 본 연구는 우리나라 초등예비교사 178명을 대상으로, 그들이 실제 교사로서 교육현장에 나서기 바로 이전 시기에 나눗셈 개념에 있어서 적절하게 개념적 지식과 절차적 지식을 관련지어 이해하고 있는지, 나눗셈에서 나누는 수와 나머지와의 관계에 대해 올바르게 이해하고 있는지 등에 관해 알아봄으로써 그들의 수학적 지식의 이해 정도를 살펴보았다. 그 결과, 대부분의 초등예비교사들이 나눗셈에 있어 개념간의 관련성과 단위에 대한 이해가 충분하지 않은 것으로 나타났다.

Since most engineering problems have had open-ended and ill-defined characteristics, design process is in advance attended with determination of alternatives based on realistic constraints after definition of appropriate problem. And it is completed with selection of best alternative through their comparison and investigation, and with performance of selected-alternative's detail design. As the process of structural design compared with that of general design, this paper presents a paradigm which can generate structural design alternatives, select optimum structure among them and simultaneously set its optimum design variables in reference of several objective as a result in more extended design region. For this purpose, specialized genetic algorithms which can handle design alternatives and multicriteria problems is used.

The purpose of this study is to investigate the effect of NIE instruction in learning mathematics. There are two groups. The one group is an experimental group which is assigned to use NIE in learning mathematics for 10 weeks. The other group is a controlled group which is received only ordinary teaching methods. The results of this study are as follows. 1. There is no significant difference in learning achievement between the experimental group and the controlled group in significant level 0.05. 2. There are some difference in mathematical disposition between two groups. That is, the students of experimental group learned NIE are not changed in mathematical disposition. However, the other group takes on negative attitude in a mathematical disposition. Considering that as the students go up higher grade, their mathematical disposition become negative, using NIE in mathematics education is valuable to prevent the negative disposition to the mathematics. 3. There are some difference between two groups in the open-ended problem test in significant level 0.05. Although using NIE has little effects in the ordinary test methods, NIE has some effects in the test which require communication ability.

The purpose of this research was to apply and conduct a class with Gordon’s Creative Problem Solving Method(Synectics) to the area of ’human development and family relations’among male students in a jr. high school. Subject matters which were appropriate for applying Gordon’s Creative Problem Solving method were selected from ’human development and family relations’area, with problem circumstances set to reflect to the highest degree the interests of individuals and families. An 8 hour teaching instructional guide was constructed with $\boxdr$strategy 1$\boxul$of Gordon’s Creative Problem Solving method in order to solve creatively the established problem. This was practically implied to 70 students(each class had 34 and 36 students respectively) in K middle school located in Seoul. The period of this application was for 3 months during March through May of 1999. The perception of this method was examined by the teachers and students through open-ended questions. The record of perception showed that 56 students out of 70(with no response from 5 students) through that the class done by the creativity problem solving method was good. The majority of reasons mentioned for the positive answers were ’being able to receive different thoughts which were unusual of daily life’. In addition the students who participated in the class were able to foster a joint experience which improved their understanding of relationships and sens of community. moreover students who did not do well n the class or were diffident were encouraged to participate which in result showed that there was even an internal effect.
