Social network services are developed which is based on interaction and collaboration between users. This used to teaching-learning and integrate personal experience based on constructivism and social learning has developed into. In order to use which better to support the N-Screen communication model is needed. Communication model is to support the interaction between learner-instructor- the system. However, until now, There are a lot of web-based communications research. In this study, Social Learning Services environment to extended to N-Screen. For seamless service, Location information of individuals to use to learning activities. To support this, the communication manager is to design and implement. Communications manager for the N-Screen services draw students use cases and define the required functions. Based on this, Communication function is designed. In addition, Considering the characteristics of each device, personal location information to be reflected.

Web provides a new instruction and learning method to get the interactive learning for people. But it is not efficient for the interaction of the education resources in the Web, and also it is difficult for the accommodative instruction to the learners who need suitable level for themselves. Therefore this thesis proposes web-based instruction system by agent technology that enables to increase the interaction, not losing their own way and learning by level, when the learners have instruction with using of web.

Distance learning (DL) has become a major issue in the educational field with the spread of COVID-19. In order to enhance the satisfaction of DL learners, efforts to cultivate learners' competencies, as well as investment to build IT infrastructure, and activities to support high-quality content provision should be comprehensively considered. Based on a survey of 221 college students, this study verified that digital literacy (knowledge, skill, and mind) and information systems success factors (system, information, and service quality) all positively affect DL satisfaction, in turn, which positively influences on DL continuance. This study is meaningful in that it comprehensively considered learner's ability and IT infrastructure and analyzed the effect on the satisfaction and intention of continuous use of DL. In the future, it is necessary to expand the target of not only college students but also elementary and secondary students and instructors, and to further consider interaction, which is a major factor in the distance learning process.

In this paper a web-based real-time education system, which is able to support education through multimedia, is suggested for the expansion of learner's creative ability in the school. This system is designed so that it can support three things: 1) a real time interaction between instructors and learners, 2) individual learning through such an interaction, and 3) a coercive distribution of display by instructions for preventing the deviation of learners from learning. Also, this system, which UML is applied to, makes efficient interaction possible through the module for the real-time exchange and management of messages even in the multi-user environment. Through this system, not only the simulation by learners can be made for experiments and practices, but also Questions and respondence can be supported on the procedure of experiments and the analysis of their results. This system is built on constructivism, and aimed at helping the learning progress and knowledge formation of learners.

영어 교육 시장이 증대되면서 영어 학습을 효과적으로 지원하는 다양한 학습 시스템들이 개발되고 있다. 영어문장을 구성하는 기본적인 단위는 어휘로 문장 전체의 의미를 파악하기 위해서는 어휘의 의미를 이해하는 것이 필수적이다. 따라서 영어 어휘 능력 향상을 위한 다양한 영어 어휘 학습 시스템들이 개발되고 있으나, 어휘가 사용되는 문맥을 고려하거나 동시에 학습하면 효과적인 어휘 등 어휘 학습에 효과적인 교수학습 방법의 원리가 적용된 영어 어휘 학습 시스템에 대한 연구는 미비한 상황이다. 본 논문에서는 n 개의 영어 단어가 하나의 그룹으로 동시에 제시되면서 그 n개의 영어 단어가 모두 포함된 예문을 제공하는 지능형 영어 어휘 학습 시스템을 설계한다. 임의로 n 개의 영어 어휘가 주어졌을 경우 문맥에 맞게 영어 예문을 자동으로 생성하는 지능형 영어 문장 생성 모델이 본 연구의 핵심이다. 또한, 어휘 능력 평가에서 기존 어휘 학습 시스템과 같이 단순히 어휘를 얼마나 암기하고 있는지에 대한 평과 결과만을 제시하는 것이 아니라, 그룹별 취약 어휘 분석을 통해 효과적인 그룹 어휘 선택 규칙을 파악할 수 있는 기반을 마련하고자 한다. 본 논문에서 제안한 지능형 영어 어휘 학습 시스템을 통해 영어 어휘 학습자들의 학습 능력 향상에 도움이 될 것으로 기대한다.

e-Learning은 시 공간의 제약 없이 교수자와 학습자간의 교육이 이루어진다는 장점이 있는 반면, 다양한 학습자의 요구를 만족시킬 만큼 충분한 학습 콘텐츠의 제작이 어렵다는 단점이 있다. 이러한 단점을 해결하기 위해 ADL(Advanced Distributed Learning)의 SCORM(Sharable Content Object Reference Modeling)의 표준에 따라 e-Learning의 학습 콘텐츠를 학습객체(Learning Object)로 제작하고, 이를 SCORM의 표준을 지원하는 LCMS(Learning Content Management System)를 이용하여 관리하려는 연구가 진행되고 있다. LCMS를 이용할 경우 학습 콘텐츠의 제사용성을 높이므로 학습 콘텐츠의 제작 및 관리가 무척 용이해진다는 장점이 있는 반면 탈맥락화된 학습 콘텐츠를 제작하기는 매우 어렵다는 단점을 가진다. 본 연구에서는 이러한 문제점을 해결하기 위해 버전관리 기법을 이용한 탈맥락화된 학습 콘텐츠에 대한 제작이 용이한 시스템을 연구했다.

There is increasing interest in text analysis based on unstructured data such as articles and comments, questions and answers. This is because they can be used to identify, evaluate, predict, and recommend features from unstructured text data, which is the opinion of people. The same holds true for TEL, where the MOOC service has evolved to automate debating, questioning and answering services based on the teaching-learning support system in order to generate question topics and to automatically classify the topics relevant to new questions based on question and answer data accumulated in the system. Therefore, in this study, we propose topic modeling using LDA to automatically classify new query topics. The proposed method enables the generation of a dictionary of question topics and the automatic classification of topics relevant to new questions. Experimentation showed high automatic classification of over 0.7 in some queries. The more new queries were included in the various topics, the better the automatic classification results.

Education in Korean universities is rapidly expanding to online education due to COVID-19. In response to such changes, this study proposed a means of improving the learning management system of Korean universities and analyzed the effects of using the system. The important results of this study are as follows: the learning management system was composed of 'pre-class learning,' 'team activity,' and 'participation learning' to support team-based learning. The effects that the users (instructors, learners) can obtain by adopting team-based learning and using the system were analyzed. The study concludes that for instructors, teaching work may be alleviated. For learners, it was demonstrated that they could more easily access and use data required for their education.

최근 디지털 지식기반 사회에 대응하는 교육의 형태로 e-Learning이 교육적 대안으로 급부상하면서, 시스템의 상호 운영성 및 컨텐츠 명세, 활용을 지원하기 위한 표준화에 따른 연구가 국내외에서 급속도로 확산되고 있다. 특히, 국제표준기관에서 제시한 e-Learning 개발 환경을 위한 Learning Technology Standard Architecture(LTSA)와 Sharable Content Object Reference Model(SCORM)을 제 정하여 컨텐츠의 사용과 상호 호환을 가능하게 함으로써 e-Learning의 효율성을 증대시키고 산업 시장의 확장을 이룰 수 있다. 또한, 현재 많은 교육관련 업체에서는 SCORM 체계를 기반으로 한 학습 컨텐츠들을 개발하여 제공하고 있다. 따라서, 본 논문에서는 국제 표준 기술인 SCORM을 기반으로 개발된 학습 컨텐츠를 체계적으로 지원하기 위해 컨텐츠 관리 시스템 개발에 대한 기술을 정의하고, 다양한 관점의 컨텐츠 메타 데이터를 식별, 분류함으로써 컨텐츠의 생성과 저장, 검색 나아가 형상관리를 위한 기본 정보로 이용 가능하다. 또한 이들 메타 데이터를 기반으로 한 학습 컨텐츠 관리 시스템의 프로토타이핑을 제시함으로써 재사용성과 유지보수성 향상을 통해 컨텐츠 개발의 용이성과 품질 및 생산성을 높일 수 있다.

I studied a group management model of virtual class for distance education system on the information superhighway. There are many objects and actions that need to be managed and controlled in virtual classes of a distance education model. Educators should be able to manage students' learning group and immediately be aware of who is attending and who is quitting the learning group in a virtual class. Also, students and educators in virtual classes can communicate and discuss various topics. I proposed a group management model for distance education on a network, and studied management algorithm and MIB (Management Information Base), which are required to manage virtual classes in distance education systems.
