Today's Web-based teaching-learning is developing in the direction that learners select and organize the contents, time and order of learning by themselves. That is, it is evolving to provide teaching-learning environment adaptive to individual learners' characteristics(their level of knowledge, pattern of study. areas of interest). This study analyzed learners' learning paths among the variables of learners' characteristics considered important in Web-based teaching- learning process using the Apriori algorithm and grouped learners who had similar learning paths. Based on the result, the author designed and developed a learning-path individualization system In order to provide learners with learning paths, Interface, the progress of learning etc. The proposed system is expected to provide optimal learning environment fit for learners' pattern of study and to be enhancing individual learner's learning effects

As the service of mobile internet has been expended, student users are increase. The computers have been widely used in a education field as the teaching tool by improvement of the multimedia contents processing and user interface. The English learning using the computers in the restricted education environment provides motivations and effective learning to learners, but still have some problem such as teaching and evaluating without consideration for differences of individual levels. In order to solve the problems and take the advantages, we propose the intelligent tutoring system for english learning with mobile technology. Overcoming limitations of the mobile environment and using proper treacher's roles,. We have applied the conventional estimation method of the intellectual learner level for students. Also, we have proposed the diagnostic function in order to determine the method of teaching-learing and item disposition that each leaner prefers. Then we have designed and implemented the expert module, providing the feedback for teaching, of the intelligent turoring system for mobile english learning. This system will be able to support the interaction between teachers and students and replace some roles of teacher in the mobile english learning.

기존의 언어교육시스템을 위한 가상환경에 대한 연구는 주로 피교육자에게 줄 수 있는 시각적인 효과에 초점을 두고 있다. 그러나, 환경의 논리적인 변화를 얼마나 효율적으로 표현으로 피교육자에게 전달할 수 있는가하는 연구는 아직 취약하다. 논리적인 모순이 존재하는 가상환경은 피교육자에 대한 흥미유발을 반감시킬 수 있으므로, 가상환경의 논리적인 모델링 기술의 개발이 필요하다. 논리적인 모델링이 된 가상환경에서 자연현상은 가상세계 전반에 걸쳐서 광범위하게 영향을 미치며, 피교육자에게 가장 큰 영향을 미치게 되므로 그 구현은 특히 중요하다. 또한, 논리적인 모델링이 된 가상환경에 접속한 피교육자의 입장에서 볼 때, 피교육자의 행동이 가상환경에 아무런 영향을 주지 못하거나 혹은 가상환경의 변화가 피교육자에게 영향을 주지 못한다면, 학습의 흥미나 몰입감이 떨어질 수 밖에 없으므로, 가상환경과 내부의 물리적객체의 상호작용의 처리 또한 중요한 문제이다. 본 논문에서는 가상환경과 그 내부의 물리적객체들간의 상호작용의 처리를 견지에 두고, 지식표현방법의 하나인 스크립트를 이용하여 가상환경에서의 자연현상 처리방법을 개발하도록 한다.

The increase in demand for e-learning has created a need to explore the implications of the emerging paradigm shift on the learning environment. To utilize information technology to improve learning processes, the pedagogical assumptions underlying the design of information technology for educational purposes must be understood. However, little theoretical development or empirical research has examined the learning effectiveness in web-based distance learning. In this regard, the primary purpose of this study is to investigate which factors of E-learning influence the effectiveness of education and expectation. Based on the prior studies of the education and business training field, research model and research hypotheses were developed. Factors studied in this paper were student characteristics, system environment and teacher characteristics. The result showed that the student characteristics has the significant effect on the effectiveness of education and expectation. However, the system characteristics and the teacher characteristics have the partial significant effects. This result is partially due to the subject characteristics of this study, because the subjects of this study are the students and they have already the experiences in IT and e-learning.
