The purpose of this study is finding factors affecting the teachers' use of Edunet and exploring the developmental direction of Edunet which is a web based comprehensive educational information service system. Based on the technology acceptance model and the results of the previous studies, five external and three internal factors influencing the use of Edunet were extracted. The participants were 100, the group of field-assistants who were expected core users in Edunet, and the response of questionnaire was gathered by online survey system. To analyze the collected data and the hypothesis, multiple regression was employed. The result indicated that "usefulness" and "trust" affected statically to both (a) the use and (b) the future-intention use of Edunet. "Fitness of instruction" and "ease of use" affected to (c) the usefulness of Edunet. (d) The ease of use of Edunet was affected by "self-efficiency", "contents quality" and "the system-performance" of Edunet.

The purpose of this study is finding factors affecting the decision of Web-based learning system (Edunet) use and searching for ways to diffuse Edunet use. Based on the diffusion of innovations theory and the results of the previous studies about web-based instruction, seven predictors influencing the decision of Edunet use were extracted. Seven variables as the followings; (1) perceived attributes of innovation (Relative Advantage, Compatibility, Complexity) (2) Innovativeness (3) Self-efficacy (4) Subjective Norm (5) Support. The participants were 315, 5-6th grade elementary school students, and the questionnaire was 20-item with 7-point Likert scales. To analyze the collected data and test the hypothesis, binary logistic regression was employed. The result indicated that the fitness of regression model including seven decision factors was proved. In addition, two factors, subjective norm and support, were identified as the important decision factors of Edunet use.

본 연구에서는 한국교육학술정보원의 교육 콘텐츠 관리 시스템인 에듀넷의 키워드 기반 콘텐츠 검색기능을 고도화하기 온톨로지를 활용한 검색 프레임워크를 설계, 구현하였다. 에듀넷의 키워드 기반 검색 시스템에서 사용하는 KEM(Korea Education Metadata)를 owl을 이용하여 온톨로지로 바인딩하였으며, 의미 기반 교육 콘텐츠 검색이 가능하도록 중학교 수학의 일부 영역을 도메인 온톨로지로 구축하였다. 구축한 온톨로지에 실제 에듀넷에서 사용하는 콘텐츠 정보를 이용하여 인스턴스를 생성하였다. 사용자의 쿼리를 입력할 수 있는 인터페이스와 쿼리를 처리하고 추론할 수 있는 추론엔진을 사용하여 본 연구의 검색 시스템을 구축하였다. 실험을 통하여 본 연구에서 구축한 시스템이 키워드 매칭을 통한 검색 보다 사용자에게 의미 있고 유용한 결과를 도출함을 보였다.

This study investigated users' information seeking behaviors associated with their perceptions of uncertainty. For this study, the data was collected from an user group, who conducted information searches in the field of history, using the KERIS Edunet system and it was analyzed through the comparative analysis of the grounded theory. The results presented users' uncertainty in the following stages: the identification of information needs, the selection of an information system, the selection of search terms, the actual use of the system, and the evaluation of search results. Major implications pertain to the enhancement of the Edunet system and related services. The former includes the improvement of the retrieval mechanisms related to the search and display interfaces. The latter emphasizes the consideration of the origin of uncertainty in the process of the services. In other words, the study suggested to consider the inadequacy of the system functions, the insufficiency of search experiences and the lack of such abilities of particular users.

Although a significant number of studies have been conducted in user-based relevance criteria, a need for further research still remains. The rational is associated with the following inadequacies: (1) research on young user groups, (2) research on the Web environment with multimedia resources, (3) research on the irrelevance criteria and implications to improve related systems and services. Accordingly, this study identified user - based relevance and irrelevance criteria, examining 40 middle school third grader students who use KERIS Edunet site. The results identified 16 relevance criteria and 8 irrelevance criteria. Major implications related to information system and service improvements.

교육 인프라의 구축과 함께, 엄청난 예산을 들인 인프라의 활용을 위한 국가적인 차원의 여러 가지 논의가 이루어졌고 결과적으로 에듀넷과 교수.학습지원센터와 같은 기관들이 탄생되었다. 하지만, 방대한 자료와 훌륭한 운영 체제를 가진 기관이라도 일선 현장에서 실제 교육을 담당하고 있는 교사들 각각의 모든 요구를 만족시키지는 못하고 있다. 교사들 각자가 생각하는 수업시간에 유용한 자료의 기준이 각각 다르고, 자료로의 신속하고 정확한 접근이 웹 상에서는 가끔 어려울 경우가 있으며. 교사들 각자의 자유로운 분류 기준을 만족시키기에는 어려움이 있다. 이에 본 논문에서는 교사들이 자신의 입맛에 맞게 교수.학습 자료를 관리할 수 있는 시스템을 구현하려고 한다.

The teaching plan is an important material for teaching and learning, and it goes through many hardships to make out it. Although these materials have been shared through web and referenced for making their teaching plan by other teachers, it has been little utilized yet in learning. In this paper, we proposed a strategy for utilizing the teaching plan as a useful material in learning and had developed the web-based system for managing and utilizing the teaching plan based on the strategy.

As modern society rapidly changes, the field of education has also developed speedily. Since Edunet system developed in 1996, many different systems are developing continuously such as Center for Teaching and Learning, cyber home learning systems, diagnosis prescribing systems, video systems, teaching and counseling, and study management systems. However, the aforementioned systems have had not great response from the educational consumers due to a lack of interconnection. There are several reasons for it. One of the reasons is that program administrators did not carefully consider the continuity of each programs but established a brand new system whenever they need rather than predict or consider the future needs. The suitable system for smart education should be one big integrated system based on many different data analysis and processing. The system should also supply educational consumers various and useful information by adopting the idea of bigdata rather than a single sign on system connecting each independent system. The cloud computing system should be established as a system that can be managed not as simple compiled files and application programs but as various contents and DATA.
