The e-learning system uses multimedia content for efficiency of a education and learner's convenience. With the web based e-learning, various multimedia services are difficult on account of physical factors such as network state and system performance. Also on the off line based e-learning, we have defects an insufficiency of interactions among learners and instructors, and an insufficiency of an adaptation about the latest information. In this study, we designed a multi-tier e-learning system using hybrid multimedia method, The proposed system can provide interaction and adaptability such as web based systems, and it can provide various multimedia content such as off line based systems. In experiments results, we know the proposed system improved users' convenience and an adaptability about the latest information, and interactions among learners and instructors when compare with existing e-learning system.

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.

컨텐츠에 대한 처리 기술과 사용자 인터페이스의 발전으로 인해, 교육 현장에서 광범위하게 사용되는 교육도구로 컴퓨터가 자리매김하고 있다. 제한된 교실 환경에서 컴퓨터를 활용한 영어교육은 학습자들에게 흥미를 유발하고, 의사소통능력의 신장을 유도하는 등의 장점이 있으나, 수준에 따른 개별학습과 상호작용 유도, 개인차를 고려한 평가 등을 수행하기 어려운 문제점이 있다. 본 논문에서는 이러한 장점을 극대화하고 단점을 좌완하기 위해서 휴대폰의 국내 표준 플랫폼인 WIPI(Wireless Internet Platform for Interoperability)기반 영어 학습 시스템을 제안한다. 제안하는 시스템은 휴대 전화의 제한성을 극복하고, 이에 적합한 컨텐츠를 활용하면서, 교사의 역할을 대신해 줄 수 있는 지능형 교육 시스템을 도입하여 교사의 역할을 대신하여 피드백을 제공해 줄 수 있으며, 교사와 학생간의 상호작용을 유도하여 학습의 효과를 극대화 할 수 있을 것이다.

서비스 로봇이 인간과의 상호작용을 하기 위해서는 상호작용에 필요한 동작들을 학습할 수 있는 방법이 필요하다. 본 연구에서는 서비스 로봇에게 동작 학습을 시키기 위한 모방학습 프레임 워크의 구축에 관한 연구를 진행한다. 모방학습에는 로봇이 행동을 수행하기 위한 모터 프리미티브가 필요하므로 본 연구에서는 선행자가 로봇을 직접 움직여 생성한 모터 프리미티브를 데이터 파일로 저장 하여 로봇에게 전송하면 로봇이 스스로 모터 프리미티브를 수행하도록 하는 모터 프리미티브 생성 시스템을 설계한다.

Congruence of figure is a basic to learn a symmetrical figure and helps to understand the characteristics of figure and know the way of drawing figures. The knowledge of congruence provides us art attainments to understand design and fine pieces of art. However, it is difficult to expect the interaction between students or between teachers and students, because of spending too much time for cutting papers and making the shapes of figure during the class for establishing the concepts. This study utilized a question-based interaction model which would foster elementary school student's learning effectiveness and make them understood the concept of congruence, also developed a congruence learning system which could communicate in both synchronous and asynchronous situation.

웹 커뮤니티 기반 온 오프라인 연계 자기주도 학습모형은 일반적으로 전통적인 면대면 교육방식이 갖고 있던 시간과 공간상의 제약 및 상호작용성의 한계를 극복하려던 e-Learning의 노력에서 한 걸음 더 나아가, e-Learning 교육 방식에 전통적인 면대면 교육방식이 갖고 있는 교육적 장점을 결합, 적절히 활용함으로써 학습효과를 극대화하기 위한 학습전략-소위 Blended Learning이다. 이에 이 논문에서는 교실이라는 제한된 범위를 넘어 다른 지역, 다른 학습자끼리 공동 관심사항에 대해 각기 자료를 검색하고, 취합하여 결과물을 공유하는 시스템을 적용하였다. 이 연구는 많은 사람들과의 연계를 통해 지기주도적 상호작용을 활성화한다는 점 이외에도 전문가 집단의 도움을 쉽게 받을 수 있으며 서로 다른 환경과 문화에 대해 통찰할 수 있는 기회를 제공해 준다는 점에서 의의가 있다.

The purpose of this study is to present a method of Korean speaking activity utilizing mobile learning. It can compensate for the shortcomings of Korean speaking classes. Currently, speaking classes in the Korean as a foreign language site are difficult to interact individually and immediately because there are one professor and several learners. So it is hard for learners to improve their speaking ability in the actual class. However, it is helpful for learners to receive instant and individual feedback and check their pronunciation, intonation and speed. by using mobile learning. Therefore, This study consists of main-activity that can correct their pronunciation, post-activity that can make free dialogues through communication between learner and learner. So learners can improve their pronunciation accuracy and fluency as well as composition of conversation. This activity was applied to the actual class and after that, the satisfaction and opinions of learners were investigated. The results showed that many learners responded positively, but also suggested that they need to supplement mobile-learning activities in classrooms and future APP developments.

The purpose of this study was to analyze the patterns and features of interaction in teacher interviewing with high school students' small group for biology learning. The interactions in variety between the students and between the students and the teacher were made as the interviews with each small group were repeated to feedback for biology learning. The patterns of interaction were categorized into four types by interactive level of interaction among group members and a teacher: leader representation without interaction among students and the teacher(LR, leader representation), interaction among a part of students and the teacher(PSI, partial students interaction), active interaction among students inside the group, but only interaction between the teacher and the leader student(SAI, students active interaction), and interaction between all of the students and the teacher(teacher-students active interaction). Even though complex patterns of interactions were made among the students at the initial stage of insufficient understanding on the study concept, the simple interaction processes were shown as students had gradually completed the understanding on the concept. It was displayed that the interaction in the small group for biology study provides the opportunity to confirm and understand the concept to the students who were poor at the understanding on the concept, and it can influence positively on the mutual creation of study concept.

With the development of Internet technology, the construction and spread of network environment increased educational adaption and utilization based on World Wide Web. Learners are educated in the competitive, individual, or collaborative learning structure. Among them, competitive and individual educational methods are criticized for bringing about excessive competition and a lack of cooperation. As a new way of educational method, the interest for the collaborative learning structure was increased. In this perspective, we design and implement a web-based collaborative learning system which is adapted the merit and model of collaboration learning and show that the proposed system improves learning achievement and motivation by experimental study on student groups.

This study was attempted to investigate the effect of non-face-to-face online classes on class satisfaction of nursing students after COVID-19. The research method was a structured self-report questionnaire targeting 3rd graders(n=133) of the Department of Nursing at K University, and the collected data were analyzed using the SPSS/WIN 25.0 program. The results of the study were achievement motivation, interaction, self-regulated learning, and achievement motivation showed a statistically significant positive correlation with class satisfaction, and self-regulated learning showed a significant positive correlation with achievement motivation. Accordingly, in order to increase class satisfaction, the development and application of non-face-to-face online teaching methods to increase self-regulated learning, achievement motivation, and interaction are required.
