As the recent paradigm of education changes to become learner-centered, there is an increasing interest in project based class as one of new teaching models. Universities are accepting this change and aiming at fostering human resources of next generations, who are able to create creative changes, and studies are being actively conducted to that end. This study suggested a learner-centered teaching model which minimizes intervention of teachers in conducting projects of main text contents in designed subjects. This study suggested support system for the suggested model project-based class, team organization method, various interaction methods of learners, and team work monitoring method of teachers. And the suggestions were designed and realized through project management applications using smart phones which are being used by a rapidly growing number of people recently.

The purpose of the paper is to apply a Data Mining method to Data Base System for more efficient educational data used in elementary and secondary education. First, this study investigated the whole contents of Data Mining and technique relation to Machine Learning. Mainly Data Base Systems in education are general life checking, record of health, and score reports. We suggested Data Mining method and Machine Learning when we search for information of usefulness in a particular representational form or a set of such representations in data. Also, we propose the problem and the solution when using data mining techniques in education.

Most of education sites which are related to practical computer lecture are almost teaming and testing based on character-contents. In this thesis, commercial high school needs the use of new application programs which appear quickly. So as teacher and students can contact with each other in classroom, we implemented self-learning which has text, visual and auditory function with the use of animation technology. Not only quantity testing which has been used for the purpose of selection and arrangement, but also we designed and implemented quality testing which consider the level and individuality of student.

As ubiquitous technology develops, there are many studies to provide various contents proper to users through a mobile device. However, there is a limit of information provision due to a small user interface of a mobile device. This study proposes a system that can solve a problem and provide an intelligent agent model appropriate to a mobile environment and job information positively that an individual user is interested. It is composed of a personalization engine to monitor users' behavior patterns and a learning algorithm to provide information to a mobile device. Analysis shows that preferred job items are different by sex, age and education, while a region affects job searching significantly.

Nowadays, Web-based bulletin board system is widely used for e-learning because of its effectiveness in communicating and information sharing. But harmful or irrelevant contents are frequently posted and these affect students in learning community based on Web-boards and the ill effect of Web-board is revealed. Some Web-boards provide features that allow users can filter specific words to resolve this problem but those features have shortcomings. Using these features the content that contains harmful words is always removed even if the whole meaning of it isn't harm and user who uses harmful words habitually cannot have an opportunity of having his/her bad habit be corrected. In this paper, we proposed new way of dealing with harmful words that overcomes those shortcomings.

We have developed a peer agent to support programming learning and analyzed its educational effects in a programming course. The agent acts as a tutor or a tutee. The role of a tutor/tutee is like the role of a navigator/driver in pair programming. While students are learning with the peer agent, the students' programming abilities are modeled. Based on the student's model, the peer agent provides appropriate feedbacks and contents to the learner. The peer agent gives positive effects on learners' achievement and self-efficacy in a programming course. It means that the peer agent system helps the learner in an affective domain as well as a cognitive domain.

We call WBI the educational program of this new teaching method which uses the web system. The instruction in WBI settings can make students feel more excited and interested in learning activities because it combined various sorts of multimedia materials such as moving pictures, graphics, and sound.. The diverse learning contents of this program not only supplement student's needs but also stimulate their creativities and application abilities. Based on the internet web courseware, this paper attempts to suggest the new program. This design implements the text, image and sound by using Explorer 5.0 in HTML, Javascript, Photoshop 5.0, Flash 4.0, and finally Gif Construction.

기존의 이러닝에서는 교수자가 강의동영상을 통하여 주로 단방향으로 지식을 전달하였다. 이런 문제점을 해결하기 위해 본 연구에서논 실시간 상호작용이 가능한 이러닝시스템인 ECube을 제안하고 구현하였다. 교수자에게는 학습자와 실시간 소통을 위한 실시간 강의기능, 전문가의 도움없이 미디어 제작과 편집이 가능한 동영상삼 저작도구인 EMC(Effective Media Contents) 솔루션을 제공한다. ECube 시스템 안의 EMC 솔루션만으로도 자막, 이미지, 퀴즈, 비디오를 합쳐 통합된 콘텐츠의 제작이 가능하다. 학습자에게는 실시간 강의를 수강하는 동안에 발표수업에 참여할 수 있는 기능을 지원하고 자신의 학습에 관한 학습계획부터 학습성과까지의 내용을 문서화할 수 있는 기능을 제공한다. 이 기능을 활용하여 학습자는 과목별 포트폴리오 작성이 가능하여 자기주도적 학습을 수행할 수 있는 학습환경을 제공한다.

Learning methods using various assistive and smart devices have been developed to enable independent learning of the disabled. Pointer control is the most important consideration for the disabled when controlling a device and the contents of an existing graphical user interface (GUI) environment; however, difficulties can be encountered when using a pointer, depending on the disability type; Although there are individual differences depending on the blind, low vision, and upper limb disability, problems arise in the accuracy of object selection and execution in common. A multimodal interface pilot solution is presented that enables people with various disability types to control web interactions more easily. First, we classify web interaction types using digital devices and derive essential web interactions among them. Second, to solve problems that occur when performing web interactions considering the disability type, the necessary technology according to the characteristics of each disability type is presented. Finally, a pilot solution for the multimodal interface for each disability type is proposed. We identified three disability types and developed solutions for each type. We developed a remote-control operation voice interface for blind people and a voice output interface applying the selective focusing technique for low-vision people. Finally, we developed a gaze-tracking and voice-command interface for GUI operations for people with upper-limb disability.
