To nurture skilled IT professionals required in the 21st information society, we have been faced to the need of learner-centered open lifelong education through the e-learning system that crosses the boundaries of time, space and geography. The object of this research is primarily as-is analysis of the IT contents in present cyber institutions, then making out the basic research data by to-be analysis and international standardization trend through benchmarking. Eventually this research intends to produce a prototype of the contents especially for the subjects related to the IT which is based on the modeling of e-Learning standard contents development model. It is possible that the final output of this project is used for the contents producing and operating data in cyber universities and institutions. This output also enhances the international competitiveness by the standardization and presents a standardized guideline to the domestic cyber education institutions.

웹 기술 기반의 컨텐츠 개발 및 운영으로 다른 환경에서의 컨텐츠 활용을 토대로 교육자원의 정보들을 통합 운영할 수 있는 관리 중심체인 e-learning 시스템의 중요성과 필요성이 대두되고 교육용 어플리케이션은 현재 표준화되지 않은 개발 프로세스를 기반하여 개발하고 있는 실정이다. 따라서, 국제적 표준인 SCORM(Sharable Content Object Reference Model)을 기반으로 높은 재사용성과 유지보수성을 극대화하기 위해 컴포넌트 개발 방법론(Component Based Development)을 적용해서 체계적으로 교육자원을 개발하고 지원하기 위한 교수-학습지원 시스템에 초점둔 연구가 요구된다. 따라서, 본 논문에서는 컴포넌트 개발 방법론중에서 Unified Process를 이용하여 교수-학습지원 시스템을 정의하고 SCORM기반의 메타데이터를 이용한 컨텐츠저장소에 관한 분석 및 설계를 한다. 이를 통해 실제 교수자가 필요로하는 컨텐츠 제공을 함으로써 재사용성 향상으로 교수-학습지원 시스템의 효율성을 극대화하고자 한다.

In order to provide a tailored education for learners within the ubiquitous environment, it is critical to undertake an analysis of the learning activities of learners. For this purpose, SCORM (Sharable Contents Object Reference Model), IMS LD (Instructional Management System Learning Design) and other standards provide learning design support functions, such as, progress checks. However, in order to apply these types of standards, contents packaging is required, and due to the complicated standard dimensions, the facilitation level is lower than the work volume when developing the contents and this requires additional work when revision becomes necessary. In addition, since the learning results are managed by the server there is the problem of the OS being unable to save data when the network is cut off. In this study, a system is realized to manage the actions of learners through the event interception of a web-browser by using event hooking. Through this technique, all HTMLbased contents can be facilitated again without additional work and saving and analysis of learning results are available to improve the problems following the application of standards. Furthermore, the ubiquitous learning environment can be supported by tracking down learning results when the network is cut off.

As society has changed to being more knowledge-based, it is indispensable that Internet usage is incorporated into education. Therefore, the e-learning system is being developed in order to provide a proper environment. However, many LCMS that were developed, currently are not based on SCORM, the world e-learning standard, nor KEM, the Korea Educational Metadata of Korea Education & Research Information Service(KERIS), and hence, it is difficult to share learning contents developed from such varied environments. National Science Museum, a non-educational institution, also provides the educational science exhibits in reality or in cyber space, which cannot be produced by elementary schools, and secondary schools. Consequently, new systems are necessary, whose modules should be divided into four, for example, 'teachers', 'learners', 'managers', and 'instructors', and be associated with each other so that they are able to integrate and manage such systems, and be used in school education as well. Therefore, in this study, more advanced LMS and LCMS, which are the web-portal sites used for a cyber science class at the National Science Museum, were designed and established. These sites were surely based on the KEM, and the SCORM.

Contents application from contents development of web technical base and with the operation different environment information of the educational resources integration the importance and necessity of the management central chain e-Learning system will be able to operate are raising its head with base. Is the actual condition which develops the development process where but, the education application currently is not standardized in base. Approaches with an educational domain from the present paper consequently, and defines MDA(Model Driven Architecture) coats e-Learning System. Also uses a studying contents standard metadata and about the contents storage space analyzes and plans the core property which uses MDA automatic tools leads and under developing boil e-Learning System will be able to provide the contents which does in actual professor own necessity.
