The present study explores how the stress of online learners is related to Korean cultural norms and social expectation and presents the criteria online education should aim at when designing instructional approaches. A sample of 176 students from a Korean online university participated in a study investigating the patterns in the academic and personal stressors they face. This study also examines stressor types in relation to sample characteristics, analyzed with a categorization method developed by extant researchers on the stress faced by U.S. college students. Unlike the findings of previous studies on college student stress, this study's results reveal that nontraditional Korean online students were faced with (1) taking on the multiple roles at work and home prescribed by cultural and social norms, and (2) challenges in regulating study habits and the learning environment as adult learners. The relevant implications for the design of online learning are discussed.

The purpose of this study is to compare student evaluation methods in team based learning classes for dental hygiene students. The subjects of this study were the score of dental hygiene students who took the courses of 'oral health education practice'. The analysis methods were spearman correlation analysis, skewness, kurtosis and Mann-Whitney U test. As a result, there was a significant correlation between the self-evaluation and peer-evaluation. Self-evaluation showed lenience tendency rather than peer-evaluation and self-evaluation found the highest central tendency. The peer-evaluation result was more lenience and more central in the group where self-evaluation was performed.

The portability and immediate communication properties of mobile devices such as UMPC influence the learning processes in interacting with peers, accessing resources and transferring data. This study explores the pedagogical potential of UMPC, being utilized in inquiry-based learning process in elementary school setting. Inquiry-based teaming, offering a powerful option for occasional projects and lab activities, is a style particularly well-suited for out-of-school programs because they have a freer hand to complement, enhance, and expand on the work that children are doing in their K-12 classes. A set of questionnaires measuring the level of interest and class achievement were answered by the students before and after the inquiry-based science class in elementary school. Statistical results show that most of the students prefer UPMC-based class to the traditional class. Some guidelines for effective UPMC-based class are also provided.

With the rapid advance of computer and communication techonology, the recent trend of education environment is edveloping in the ubiquitous learning (u-learning) direction that learners select and organize the contents, time and order of learning by themselves. Since the amount of education information through the internet is increasing rapidly and it is managed in document in an effective way is necessary. The document clustering is integrated documents to subject by classifying a set of documents through their similarity among them. Accordingly, the document clustering can be used in exploring and searching a document and it can increased accuracy of search. This paper proposes an efficient incremental clustering method for a set of documents increase gradually. The incremental document clustering algorithm assigns a set of new documents to the legacy clusters which have been identified in advance. In addition, to improve the correctness of the clustering, removing the stop words can be proposed.

The purpose of this study was to seek strengths and weaknesses from analyzing Korea and U.S. science textbooks in terms of general structural features, contents, cognitive levels of questions and the purpose of questions used in science textbooks. This provided insight into improvement of textbooks that can effectively assist teaching and learning. To investigate organization of unit in textbooks in-depth, the evolution unit was selected and scrutinized as one example. The results showed that the number of pages, activities, vocabulary words, and vocabulary lists are considerably different between Korean and the U.S. Commonly, U.S. textbooks were more laden with information and lacking in coherence than those of the Korean textbooks. The findings on the cognitive levels of questions showed that the majority of questions in both nations are concerned with knowledge. However, the difference between the two nations is great in the ratios of analysis, synthesis, and evaluation questions. Questions are concentrated in review section (45% of Korean and 60.6% of U.S.) in textbooks. It suggested that well-planned questions in a review section can provide the basic guidance for strength in a science classroom.

As the educational use of intelligent service robots has been proved to be effective, educational service robots have been utilized in kindergarten. In addition, service robots will be used in elementary schools from 2010 for the after-school English program. This trend indicates that r-Learning using service robots will become a major educational paradigm in preparing for future education. This article consists of the following four parts. First, the concept and the type of educational robots were defined and the trend of previous research was examined. Second, the characteristics of robot-assisted learning were analyzed as a part of r-Learning, and difference between r-Learning and u-Learning was compared. Third, the contents and service using a robot-assisted learning system were discussed, the models and trend of service using the robot-assisted learning system were examined, and the aspects of viewing evolution were compared. Finally, suggestions for activating the service market of robot-assisted learning were made for the educational institution, research institution, government and robot companies.

In ubiquitous environment, the analysis for student's learning behaviour is essential to provide students with personalized education. SCORM(Sharable Contents Object Reference Model), IMS LD (Instructional Management System Learning Design) standards provide the support function of learning design such as checking the progress. However, in case of applying these standards contain many problem to add or modify the contents. In this paper, We implement the system that manages the learner behaviour by hooking the event of web browser. Through all of this, HTML-based content can be recycled without any additional works and the problems by applying the standard can be improved because the store and analysis of the learning result is possible. It also supports the ubiquitous learning environment because of keeping track of the learning result in case of network disconnected.

This study is to analyze the implications of effective learning in a ubiquitous environment. Research proceeded according to the multiple case study analysis method. This paper is one result of the Korean case study to examine the effectiveness of and satisfaction with u-learning. We will introduce necessary conditions for effective learning in a ubiquitous environment. Each condition was elicited through the case study, and the analyzing framework was classified into hardware related to infra structure; software such as learning contents, teaching-learning activity and support, and class management; human-ware related to learner and teacher; system-ware as an education system, and administrative supporting.

지식정보화 시대에서 정보는 사회적 부를 창출하는 수단이며 그 자체로서 가치를 지니기도 한다. 하지만 사회적 약자인 장애인들은 정보접근과 활용에서 소외되고 있다. 이를 해결하기 위해 웹접근성을 향상시키는 것이 중요한 문제이다. 이에 본 논문에서는 웹접근성의 의미와 u-러닝의 의미, 그리고 u-러닝이 주는 학습적 효과를 알아보고 u-러닝 콘텐츠에 웹접근성을 향상시켰을 때 얻을 수 있는 이점에 대해 알아보고자 하며, 장애인의 웹접근성을 향상시키는 u-러닝 콘텐츠를 개발하는 데 목적이 있다. 본 연구에서는 다음과 같은 제안을 한다. 첫째, 시작장애인을 위한 보조기능이 존재해야 한다. 둘째, u-러닝 콘텐츠의 색채구성에 유의해야 한다. 셋째, 청각장애인을 위한 서비스를 제공해야 한다. 넷째, 장애인에게 적절한 모바일 기기를 선택해야 한다.

과거 수천 년의 역사를 통째로 바꾸어놓았던 산업혁명 이상의 거대한 변화가 가까운 미래에 인류를 기다리고 있고, 이에 세계각국은 융합인재양성에 주력하고 있다. 한국은 지난 20년 동안 인터넷 및 유비쿼터스 혁명을 거치며 스마트러닝과 유시티라는 훌륭한 솔루션과 인프라를 만들어냈으며, 이러한 발전의 연장선상에서 융합인재양성의 중요한 배경으로 이들을 활용해야만 한다. 미래를 위한 교육과 교육콘텐츠는 도시와 나라의 산업역량이 함께 융합되어 이루어져야한다.
