The recent paradigm of web-based teaching-learning is changing into a direction that analyzes the learning patterns of learners on the basis of learners' ability, aptitude, request, interest, learning history, activity profile, etc. and provides adaptive environment with individual learners The present study analyzed learners' learning patterns using data on learning activities and developed a personalization system that provides learning environment adapted to individual learners. This study customized in three aspects, which are recommendation of learning path, recommendation of interface and recommendation of interaction, through Web mining. The personalization system developed in this study was proved to be effective in improving individual learners' satisfaction with learning in Web-based teaching-learning environment.

In this study, we will explain the concept of an organized and collective web based project learning system and suggest a basic structure concentrating on the learners. The web-based project learning system enables learners to use the diverse information on the internet any where, any time. Also the project system aims to go beyond classroom education and achieve learner-focused education with a project based on the students' tastes.

The web-based discussion allows learners to participate in the learning actively and positively, and it can provide learners with the learner-oriented active interaction and learning environment. However, the web-based discussion produced communication-oriented learning environment using bulletin board and data directory and researched mainly the state and activation of the discussion, and had less system supporting dynamic discussion process. Even if the discussion made appearance partially and totally as learners' activities at a variety of web-based teaching, specific discussion-based teaching model was not developed. Therefore, a systematic web-based discussion system needs to be developed to activate human interaction and to give shape to the stages and elements of the discussion model. The paper supports dynamic discussion activities and applies Hill's common discussion model describing detailed discussion stages to develop systematic web-based discussion system.

The purpose of this study was to design a system of web-based discovery learning and testify its effectiveness, in order to complement the difficulties of discovery learning considered to be hard to be applied to the school education because of shortage of time and materials, though discovery learning is one of inquiry learning emphasized in the 7th national curriculum of elementary science. As for the process of testifying, it compared the differences between comparative group with normal discovery learning model and experimental group with web-based system of discovery learning model, targeting the subject of extending spring among the 4th grade science. As a result, the experimental group achieved higher academic performance compared to the comparative group applied to the normal discovery learning model.

The appearance of web technology has accelerated the role of the application of multimedia technology, computer communication technology and multimedia application contents. Recently WBI model which is based on web has been proposed in the part of the new activity model of teaching-teaming. How to learn and evaluate is required to consider individual learner's learning level. And it is recognized that the needs of the efficient and automated education agents in the web-based instruction is increased But many education systems that had been studied recently did not service fluently the courses which learners had been wanting and could not provide the way for the learners to study the learning weakness which is observed in the continuous feedback of the course. In this paper we propose design of multi-module system for course scheduling of learner-oriented using weakness analysis algorithm. First proposed system monitors learner's behaviors constantly, evaluates them, and calculates his accomplishment and weakness. From this weakness the multi-agent prepares the learner a suitable course environment to strengthen his weakness. Then the learner achieves an active and complete teaming from the repeated and suitable course.

It is making researches in questions selection method for examination in web-based education system. Most questions made for these remote examinations use methods of making questions using fixed questions or randomly using item pools or automatically using degree of difficulty. This paper proposes a new examination questions selection algorithm in web-based education system for engineer test. Generally, Engineer test is characterized by adequate examination questions selection for degree of difficulty and equally between all units. Therefore this algorithm selected examination questions equally well as regards degree of difficulty and distribution between all units. This algorithm providers more effective education examination method as compared with previous algorithm.

최근 웹의 폭발적인 성장으로 인하여 웹을 교육의 매개체로 활용하려는 노력이 활성화되고 있다. 그러나 현재 대부분의 웹 기반 교육 시스템들은 대체로 수동적이며, 정적인 하이퍼텍스트 위주이기 때문에, 학습상황을 수시로 점검할 수 있는 상호작용기능이 부족하고, 특정 학습자의 학습결과에 따른 동적인 학습환경의 제시가 어렵다. 일반적으로 웹기반 교육시스템은 다양한 지식계층의 사람들에게 노출되어 있기 때문에 보다 상세한 학습전략이 요구되며, 따라서 최근에는 기존의 지능형 교수시스템(Intelligent Tutoring System: ITS)에서 연구된 풍부한 기술들을 웹 환경에 도입함으로서 보다 지능적이며 적응력 있는 시스템개발에 관한 연구가 활성화되고 있다. 본 연구에서는 이러한 웹 기반 교육시스템에서의 문제점들을 해소하기 위한 한가지 방안으로 ITS의 동적 교수계획기법을 웹 기반 시스템에 도입한다. 문제영역으로 C 프로그래밍 언어 학습을 선정하여 이를 웹 기반 교수시스템으로 설계하고 구현하였다. 또한 기존 시스템들의 서버 집중형 구조에서 탈피하여 CORBA를 이용한 분산기반구조로 시스템 개발에 접근하였다.

Web-Based instruction system implemented according to CGI based process-oriented. But, in case of system development, theses method is able to take inefficiency with duplication of program code. Also, ofter the development, it takes difficult on the operation and management. In this research, I implement Web-based score processing system by component composition. Applied component model is Java Beans and composition method is to use Chiron-2 architecture. By this method, this research shows the high efficiency - not only structural advance but also low value of cyclomatic complex that measure a maintenance.

최근 초고속 통신망의 보급과 World Wide Web의 눈부신 발달로 인하여 상호작용적인 웹 기반 협동학습이 활성화되고 있다. 그러나 기존 웹 기반 협동학습 시스템의 대부분은 일정한 기준이 없이 그룹이 편성되거나 오프라인에서 그룹이 편성되도록 되어있다. 또한, 협동학습 이후 평가가 없거나 오프라인에서 평가를 하도록 구성되어 있다. 그러므로 기존의 웹 기반 협동학습은 외형상으로는 협동학습을 표방하지만 완벽한 웹 기반 협동학습이 될 수 없었다. 본 논문에서는 이러한 웹 기반 협동학습의 단점들을 보완하여 학습자의 적극적 협동수행 유도와 학습효과의 증진이 가능하도록 하였다. 그룹 구성부터 시작하여 평가에 이르기까지 모든 것이 웹 상에서 가능한 시스템을 설계하였다. 일정한 기준을 통한 성향조사를 통해 교수자가 웹 상에서 동질적, 이질적 성향의 그룹 편성을 가능하게 하였으며 교수자가 학습자의 성향을 모르는 상황에서도 적당한 그룹의 편성이 가능하도록 하였다. 웹 기반 협동학습 종결 후 자기평가, 동료평가, 그룹평가, 그리고 교수자 평가와 같은 다양한 평가방법을 도입하였다. 이러한 다양한 평가에 의한 피드백을 통하여 학습자가 새로운 협동학습에서 보다 더 적극적이고 능동적인 협동학습을 하도록 하였다.
