In this study, messages from on-line discussions of 28 preservice teachers were analyzed based on social constructivist learning theory. After preliminary discussion session for a week, small group discussions were conducted every single week with different topics during 4 weeks. One transcript with most frequent messages in each topic was selected, and a total of 72 messages were analyzed. Discussion topics were the issues related to the nature of science. The Interaction Analysis Model for Examing Social Construction of Knowledge in Computer Conferencing was used for the analysis. Analysis of the messages indicated that 'sharing information' was the most frequent, and that 'discovering/exploring dissonance' and 'negotiation of meaning/co-construction of knowledge' were the nex. However, messages of 'testing and modification of proposed synthesis' and 'testing and application of newly constructed meaning' were found to be rare. This result indicated that students' interaction through on-line discussion did not reach to the social construction of knowledge.

본 논문은 지식경영의 기술적 기반을 확보하고 숨어있던 지식을 명시화하여 공유하는 데 성과를 거두고 있는 지식경영 선도기업들이 지식경영 활동을 업무 성과와 직결시키기 위해 시도하고 있는 활동들에 주목한다. 지식경영이 업무와 별개로 이루어지는 것이 아니라 업무 프로세스와 통합되기 위해 필요한 요인들을 탐색하기 위해 우선 현장 전문가들을 대상으로 조사를 실시하였고, 그 결과를 반영한 설문지를 바탕으로 지식경영 사용자들을 대상으로 조사를 실시한 후 확인적 요인분석 기법을 활용하여 각 요인들의 타당성을 검증하였다.

Though there is no agreement on the definition of analogical reasoning, there is no doubt that analogical reasoning is the means of mathematical knowledge construction. Mathematicians generally have a tendency or desire to find similarities between new and existing Ideas, and new and existing representations. They construct appropriate links to new ideas or new representations by focusing on common relational structures of mathematical situations rather than on superficial details. This focus is analogical reasoning at work in the construction of mathematical knowledge. Since analogical reasoning is the means by which mathematicians do mathematics and is close]y linked to measures of intelligence, it should be considered important in mathematics education. This study investigates how mathematicians used analogical reasoning, what role did it flay when they construct new concept or problem solving strategy.

In this paper, we analysis a competition to organize knowledge map as initial prepare stage based on intellectual property. We also propose the method that can be used to constitute knowledge map related in area to use basic data. In order to extract analysis data, we choose LED as an analysis technology. We provide the result of total analysis for LED application area through analysis of patent level after we extract recent patent ratio, activity index, patent family size, cites per patent as center of patent data.

If the philosophy of the curriculum is changed when the curriculum is revised, discussion about knowledge viewpoints in the changed philosophy is needed. The purpose of this thesis is to analyze elementary mathematics textbooks(EMT) based on the perspective of constructivism knowledge as basic philosophy of the 7th curriculum and the 2007 revised curriculum and to present aim of textbooks development through the results. According to the results, the number and operation units of 1st and 2nd grades of EMT compiled according to the 7th curriculum and the 2007 revised curriculum didn't reflect the perspective of constructivism knowledge as the philosophy of the curriculum. From the analysis, EMT were not composed so as to agree the perspective of constructivism knowledge that emphasize concepts, conceptua1 principles, variety, integration.

The purpose of this research was to confirm one of constructivists' assumptions that even children 조o are with low reasoning ability can make reflective abstracting ability and cognitive structures by this ability can make generation ability of new knowledge by themselves. To investigate the assumption, learner-centered instruction were implemented to 2nd grade classroom located in Suseong Gu, DaeGu City and with lesson plans which initially were developed by Burns and corrected by the researchers. Recordings videoed using 2 video cameras, observations, instructions, children's activity worksheets, instruction journals were analyzed using multiple tests for qualitative analysis. Some conclusions are drawn from the results. First, even children with low reasoning ability can construct mathematical knowledge on multiplication in their own. ways, Thus, teachers should not compel them to learn a learning lesson's goals which is demanded in traditional instruction, with having belief they have reasoning ability. Second, teachers need to have the perspectives of respects out of each child in their classroom and provide some materials which can provoke children's cognitive conflict and promote thinking with the recognition of effectiveness of learner-centered instruction. Third, students try to develop their ability of reflective and therefore establish cognitive structures such as webs, not isolated and fragmental ones.

This research explores the role of personal performance expectation, task-technology fit, perceived rewards, shared vision, usefulness of knowledge sharing, top management support, organization culture, organizational commitment, KMS self-efficacy as antecedents which affect knowledge sharing activity as a consequence and investigates relationships among variables considering characteristics. The results show that members' perceived personal performance expectation, task-technology fit, perceived rewards, shared vision, usefulness of knowledge sharing, top management support, organization culture, organizational commitment, KMS self-efficacy has a positive effect perspectively on knowledge sharing in a organization. Especially, the fact that perceived members' task-technology fit, perceived rewards, usefulness of knowledge sharing is more important than other variables was confirmed. The results of this study, knowledge-sharing activities of the enterprise, members of the organization's business strategy for the activation process is expected to help.

This is the second segment of an action research on the constructivist geography education.(1)Deeper and lasting construction of knowledge may be possible especially when some key or leading concepts are utilized, around which other related concepts may be further explored. (2) Graphic languages may be more pedagogically effective than any other language, when they are viewed as means of learning may be the teacher's questioning, cooperative discussion, and the teacher's guidance and assistance. The questioning by the teacher seems effective when it is appropriate to the different levels of learner's comprehension, and cooperative discussion among thern seems productive with the teacher's attentive guidance. And, (5) constructivism may best be understood when teachers try to embody it in their own classrooms. This may be part of the context in which action research is called for.

지금까지 수행된 대부분의 유가예측은 주고 계량 데이터를 기반으로 하는 여러 가지 계량 모델을 구성하여 수행되었으며, 그 결과 산유국 동향과 같은 국제 유가시장의 불확실성을 제대로 반영하지 못했다. 따라서, 본 논문에서는 이러한 문제점을 해결하기 위하여 계량경제학적인 접근방법과 전문가시스템을 통합한 유가예측 시스템을 설계 및 구현하였다. 즉, 계량 데이터를 기초로 유가예측 모델을 구성하고, 산유국동향과 같은 비계량적인 요인이 유가에 미치는 영향에 대한 실무자의 경험적인 지식은 지식베이스로 구축함으로써, 유가예측과 관련된 다양한 요인들을 폭넓게 고려할 수 있는 통합된 시스템을 개발하였다. 유가예측 모델로는 대표 유종의 유가 및 수급 전망을 위한 동적 선형연립 모델과 유종간 유가의 균형차액을 예측하기 위한 Fully Modified 공적분 회귀분석 모델을 구성하였으며, 유가예측 모델에서 반영하기 어려운 산유국 동향이나 OPEC정책, 선물시장 동향 등은 실무자의 경험적인 지식을 바탕으로 시스템 예측변수로 설정하여 유가예측에 반영할 수 있도록 지식베이스를 구축하였다. 또한, 본 시스템에서는 유가예측 이외에 석유 수급을 전망하고, 유가 및 수급과 관련된 다양한 정보를 제공하고 관리하는 기능을 제공하고 있다.
