In this paper, we present the design and implementation of a web-based distance learning system supporting the collaborative browsing. Our system consists of an education affair management system, a video conferencing server/client, a white-board server/client, a session manager and a web browser sharing system. Among other things, our collaborative web browser is unique and not found in any other system. The web browser shows synchronously the same web pages as the lecturer moves through them. Therefore, it allows the student to feel real-time surfing gust as the lecturer would. The session manager supports multi-user and multi-group, and integrates various synchronous collaborative component into one distance learning system by providing the same session data and information of users in a session group. Our collaborative browsing system can increase the efficiency of distance learning and provides the effect of learning in the same classroom by supporting various synchronous functionalities, such as collaborative browsing.

This paper describes an experiment of concrete and specific group work learning system based on the traditional Jigsaw group work learning model. Jigsaw model has two groups of students such as random group and expert group so that a course can make progress on explaining and lecturing all members of class after each student can be a member of expert group of course topic. We design and implement Web-based training system to support collaboration and Interaction among students of a course based on Jigsaw model The Web- based learning system makes each group going up to the expert level of a course subject by supporting various study menu and provides equal opportunity of improving social abilities such as leadership, communication skill, trust, and trouble-settling by taking part in collaboration activities.

Science education in elementary school is mostly based on solving investigative tasks conducted by small groups on the basis of the inquiry activities such as experiments, observations, etc. Students should be able to draw conclusions from experiments and observations through their collaborative interactions by exchanging ideas. If learners use the advantages of Blended-Learning as a new pedagogical method comprehending merits of both off-line and on-line learning to complement off-line activities throughout the entire process, the interactions among them may be reinforced, and they would take part in the inquiry learning more actively. Accordingly, the proposed system can help children foster science inquiry learning effectively by using on-line communication facilities to arrange learners' diverse opinions and thoughts coming from off-line inquiry activity process. The result shows that the system enhanced learners' interest about science inquiry learning and improved their learning achievements by exchanging diverse opinions via the Web communication facilities.

One of the cooperative learning models, the cooperative learning of structural approach which is very simple and easily applicable accomplishes teaching-learning through combining learning contents and organic connections of various structures. This work proposes a cooperative teaching-learning model for the structural approach, designs and implements a web-based cooperative system supporting it. The model provides a concrete frame which can apply to a subject learning thus could effectively support cooperative learning. Furthermore, it classifies learning into three types such as knowledge learning, investigation, and function mastering and presents a structure application model for each so as to apply different structures according to learning materials and types. We implemented a system that performs cooperative learning on the basis of these models, applied to a class, and analyzed the effect of it.

To follow in change and the development which circumference environment of education are quick even from scene of education students form the structure of knowledge themselves, the place where own lead studying of personal small group studying is emphasized, here upon specialist learning activity there is a wild possibility in the model which is suitable. But, studying of the learning paper was most center mainly the specialist learning activity of existing, it solves a learning problem at unit hour to, the hour was too insufficient to solve and it became plentifully at block time. But, this is to the curriculum operation and or the schedule operation it is when trying to consider the intensive degree of learning the elementary student, a problem point there is. It grasps the strong point and a weak point of specialist learning activity model of existing from the research which consequently, it sees and it applies more efficiently from web base study to establish the instructional strategy for, it composed the modules which strengthen the interaction of learning subject for. Also, unit macro learning and block time learning in order to do to become accomplished at web with studying problem, it will be able to solve inside unit hour in order, specialist teaching-learning system based on the web. It developed, after applied in the electrification S elementary school 5 grades which will reach the result, it analyzed.

논문에서는 최근 인터넷 상에서 표준 공통 포맷으로 대두되는 XML을 이용하여 웹 기반의 역사자료의 데이터베이스 검색 시스템을 설계 및 구현하였다. 원격 교육 시스템의 참조문헌 지원 시스템을 설계하였다. 컴퓨터 상에서 고문헌 자료 주로 한자를 입력하고 검색할 수 있는 환경이 점차 나아지고 있다고는 하지만, 여전히 원전사료의 한자를 일반적인 환경에서 자유롭게 구현하는 일은 결코 용이하지 않다. 종래의 연구자들은 텍스트 별로 수작업으로 작성한 색인류를 이용하여 연구를 해왔다. 그러나 이러한 색인 이용방법에는 문제가 있다. 색인어로 삼고자 하는 단어를 텍스트에서 추출하는 과정에서 누락되는 경우가 있기 때문이다. 전산화된 데이터는 이른바 '발견적 이용'이라는 관점에서 활용될 수 있다.

E-learning education methodology using the web has been as much activated with the introduction of the internet to our society. As for the web-based education, there is no exception in case of mathematics. However, when it comes to representing math equations by using HTML image tags, a type of web marked-up language, it can be hard to represent math equations that have structural features, and to do the search, resulting in the difficulty in reusing math related applications. Therefore, based on MathML and using ActiveX control technology, a math equation generating website was designed and implemented in this study. Since this system employed ActiveX control technology, it is possible to generate math equations without the limit of time and place on the web, and to manage the program with the most up-to-dale version. And in this system, it is also possible to save the math equations generated in this system to be referred to for their reuse in the future.

In the recent field of education, they open career-related curriculums either as formal curricular programs or extracurricular programs as highlighting value of career education. However, this lecture-based career education has failed to attract students' interest, and results are not satisfactory either. Since then, in order to design entertaining career education, the field has developed diverse tools and as a vocational aptitude testing tool for career development, methods that would use vocational cards were introduced. Today, schools from elementary school to middle and high schools frequently make use of the cards to conduct the vocational aptitude test and yet, as this web-based learning and smartphones are distributed, changes in the testing tool are being intensely demanded. This study aims to create and implement an application to help the vocational cards-using vocational aptitude test targeting students in elementary, middle and high schools to be actually conducted in a mobile platform.

현재 국내에서 웹을 기반으로 한 e-learning 콘텐츠는 많이 개발되고 있으나 이들 대부분이 매뉴얼 식으로 제작되어 멀티미디어 형식만 빌려 텍스트 형태로만 구성하는 방식이 주를 이루고 있는 실정이다. 따라서 본 논문에서는 SMIL을 기반으로하여 멀티미디어 아날로그와 디지털 자료를 융합할 수 있는 핵심 기술을 제안하며, 이를 웹 상에서 창의적이고, 자기주도적으로 개인차에 따라 학습 속도를 조절할 수 있는 프로젝트 학습기법을 국내 교육환경에 맞게 교수-학습 이론을 적용하여 설계 구현하였다.

In present, an education paradigm of new info-age is consisting by using the Internet in education field, and as that practical use of internet in education is in increasing trend and various education method is showed. Also, as using the web by teacher and student, teacher can achieve efficiently instruction and student management and students can handle various kinds item about studies efficiently. But much of the existent systems were drived on instruction management, systems of student management are very few. Therefore, in this paper, we designed and implemented system that can efficiently manage instruction and student in web. Implemented system was designed by dividing teacher module and student module and various function for instruction management and student management were included in teacher module and in student module include various functions with related to as class, report and result record.
