Mobile learning, which provides educational services with a mobile platform, has been greatly expanding with the increasing spread of digital devices. The transition from PC-based online education to mobile-based education enables users to access online education anytime and anywhere. Despite this expansion of mobile learning, there is a lack of user-oriented content design. Therefore, this study intends to derive a measure to evaluate usefulness of the content design. We conducted a literature survey to reflect characteristics of existing measures, which evaluate usefulness and content of mobile learning. As educational mobile applications have both educational service and mobile device features, they can be representative of pedagogical usability criterion and can be divided into system and content areas to further develop effectiveness of learning. We conducted questionnaires on the use of these applications on 15 experts using the del phi technique. The analysis suggests the ease of use, learning efficiency, aesthetics, and ease of learning to be criteria of pedagogical usability. This study expects to serve as a basis to improve the usability of mobile learning users.

원격교육과 e-러닝의 차세대 형태로 모바일 교육에 대한 관심이 급증하고 있다. 이러한 모바일 교육은 스마트폰을 중심으로 전개되고 있으며 사이버 대학교뿐만 아니라 일반 오프라인 대학에서도 적극적인 움직임을 보이고 있다. 본 논문에서는 u-캠퍼스 환경기반에서의 모바일 교육 서비스 시스템을 설계하였다. 모바일 교육 서비스 시스템은 u-캠퍼스 환경기반에서 교육 수요자들인 학생들에게 시공간의 제약 및 디바이스에 제약이 없는 학습 환경 시스템을 제공하고 모바일 캠퍼스 플랫폼 기반의 m-러닝 시스템을 설계한 것이다.

휴대폰이나 PDA와 같은 모바일 기기의 확산과 더불어 모바일 통신 환경을 기반으로 하는 모바일 교육 학습 모델이 교육의 질향상 및 교육 효과의 극대화를 꾀할 것으로 기대되는 실정이다. 또한 모바일 환경에서 학습자가 지속적이고 자기 주도적으로 학습을 하기 위해서 자기조절학전략이 필요하며, 이를 위해 모바일 학습환경에 적합한 MMIS(Motivation Metacognitive practice Interaction. Self-reflection: 자기 주도학습전략)모형을 설계하도록 하였다. 특히 학습자의 지속적인 흥미와 동기부여를 위해 에튜테인먼트(edutainment)전략을 활용하여 모바일 게임에 익숙한 학습자의 특성에 맞는 모형으로 설계하였다. 본 논문에서 설계한 MMIS 모형의 특징은 다음과 같다. 첫째, 학습자가 스스로 학습 전략을 계획하고 통제할 수 있도록 게임의 난이도를 스스로 결정할 수 있다. 둘째, 학습자가 게임활동을 스스로 계획하고, 게임 결과를 모니터링 할 수 있다. 셋째, 사전에 게임에 필요한 학습 내용을 제공받음으로써 게임에서 좋은 결과를 얻기 위한 노력을 할 수 있도록 하였다. 넷째, 게임을 할 때 해결하기 어려운 과제의 경우에는 교사나 게임에서 제공되는 힌트를 통해 스스로 필요한 도움을 찾아낼 수 있다.

인터넷 사용이 보편화됨에 따라 컴퓨터뿐만 아니라 휴대폰이나 PDA(Personal Digital Assistant) 등의 모바일 디바이스를 사용한 인터넷 이용이 증가하고 있는 추세이다[l]. 이에 웹상에서 제공받던 교육용 컨텐츠를 모바일상에서 제공해야 하는 필요성이 대두되었다. 교육용 모바일 컨텐츠는 사용자에게 유익한 정보를 편리하게 제공할 뿐만 아니라 신속하고 정확하게 제공하는 장점이 있다[2]. 본 논문에서는 WAP(Wireless Application Protocol)을 기반으로 하여 다운로드 솔루션을 채택한 GVM(General Virtual Machine)상에서 실행되는 교육용 모바일 옥편을 설계하고 MoibleC를 사용하여 제작하였다. 또한, 제작 과정을 통해 단말기의 제한적 환경에서 교육용 컨텐츠의 효과적인 개발 모델을 제시해 보고자 한다.

The computing environment is rapidly changing to mobile device base, with the development of computer technology. Until now, digital literacy education has been based on desktop PC education, but it is time to change it into literacy education suitable for mobile environment. In this paper, we propose a mobile-based digital literacy MoDL (Mobile Device Digital Literacy). MoDL proposes three phases. One is Mobile Based Digital Environment (MoDE), which builds a mobile digital environment, seconds is Bring Your Own Devices (BYOD) class method when using it for education. Finally, MoDLI (MoDL Instruction) for learning mobile literacy is presented step by step. To verify the validity of the proposed, eight experts were surveyed so that the Content Validity Ratio was calculated. As a result, CVR was ensured in all items except for the applicability of MoDLI.

최근 스마트폰 및 타블릿PC 등 모바일 장치의 성능(쿼드코어)이 급격히 성장하고, 사용자의 증가, 무선 통신 환경(LTE, Wibro 등)의 발전으로 모바일 장치들을 연산 가능한 자원으로 고려하는 모바일 클라우드 연구가 이루어지고 있다. 그러나 자원 제공자인 모바일 장치의 자율적 연산 참여와 탈퇴가 가능하기 때문에 기존의 시스템들은 수행중인 연산이 중단되어 연산의 완료 시간이 지연되며, 시스템의 결함으로 이어지게 된다. 따라서 모바일 장치의 안정적인 연산 수행을 위한 안정적인 모바일 자원을 제공해야 한다. 본 논문에서는 신뢰적인 모바일 자원을 제공하기 위해 소셜 네트워크 정보를 이용하여 그룹화 함으로써 모바일 자원 관리를 제공한다

There are various types of educational contents in mobile world. Moreover new and various kinds of contents have been developed recently according the smart phone has become popular. Therefore, many telecommunication companies of domestic and overseas are showing many kinds of smart phone as to customers are growing more and more interested in mobile devices. Currently, most of the language educational contents are composed to foreign languages like English, Japanese, Chinese, but the development of Korean educational contents are inadequate. In this paper, so, we design the linguistic contents for beginning Koran education of foreigner which are used on mobile platforms.

A large part of the wireless Internet contents which the young people access through their mobile phones is mobile games. However, mobile games currently available in the market are mostly simple entertainment packages, and there are hardly any educational game contents. This research divided the middle school computer education curriculum into five parts-common PC knowledge, operating systems, word processor, Internet, and multimedia-and designed and implemented a crossword puzzles mobile game. The mobile game designed in this research was given an emphasis to allow access of school lesson contents anywhere and anytime through actual mobile telecommunication networks, so that the students may experience less barrier to more fun and entertaining educational contents. The developed educational mobile game was applied on 2nd year middle school students. The mobile game had positive educational effects.

As the educational media tends to be more digitalized and individualized, the learning paradigm is dramatically changing into e-learning. Existing on-line courseware gives a learner more chances to learn when they are home with their own PCs. However, it is of little use when they are away from their digital media. Also, it is very labor-intensive to convert the original off-line contents to on-line contents. This paper proposes education mobile contents(EMC) that can supply the learners with dynamic interactions using various multimedia information by recognizing real images of off-line contents using mobile devices. Content-based image retrieval based on object shapes is used to recognize the real image, and shapes are represented by differential chain code with estimated new starting points to obtain rotation-invariant representation, which is fitted to computational resources of mobile devices with low resolution camera. Moreover we use a dynamic time warping method to recognize the object shape, which compensates scale variations of an object. The EMC can provide learners with quick and accurate on-line contents on off-line ones using mobile devices without limitations of space.

The purpose of this study is to examine how time management, usefulness, and interest predict m-learning outcomes. For this study, 144 high school students participated in m-learning activities during science classes. After 5 week of classes, they responded the following surveys: time management, usefulness, interest, satisfaction, perceived achievement and learning persistence. Multiple regression analyses with correlation applied to this study as a data analysis method. The results showed that time management, usefulness, interest significantly predicted learning satisfaction and persistence. In addition, time management and usefulness significantly predicted perceived achievement, Therefore, these findings imply that time management, usefulness should be considered for designing m-learning activities in high school science class.
