The importance of the mathematical education on the ICT environment has been increased as the educational environment has been changed in 21st century. In Korea, many researches on ICT tools have appeared over the last 10 years. But most of researches are depending on the foreign tools, that was one major obstacle on adapting them in our mathematics curriculum. But we found the new open source tool which is called Sage-Math can be in effective solution to resolve those problems. Now we produce what we have done in linear algebra with this Sage-Math and mobile modules.

클라우드 컴퓨팅의 개념은 2006년에 처음 나왔다. 이것에 대한 정의는 내려졌지만 서비스 제공자들의 이해에 따라 조금씩 차이가 있다. 현재 아마존과 구글같은 글로벌 기업에서는 클라우드 서비스를 선도하고 있고, 더욱이 모바일 시장이 급성장 하고 있는 현 시대에서 모바일 클라우드는 더욱 앞서나가는 서비스 모델이 될 것으로 전망된다. 하지만 모바일기기는 분실 및 도난의 위험이 높다. 현재 사용 중인 모바일 클라우드의 인증 방법들은 기존 클라우드의 인증방법을 그대로 사용하고 있어서 타인의 모바일 기기를 악의적인 사용자가 습득할 경우 쉽게 인증을 통과 할 수 있다. 따라서 모바일 클라우드 환경에서 사용자의 인증을 더욱 안전하게 할 수 있는 방법이 필요하다. 본 논문에서는 모바일 기기를 이용하여 상황인식을 기반으로 한 인증방법을 제안한다.

우리의 교육은 다양한 매체의 등장과 기술의 발달로 인해 이러닝, 모바일 러닝, 소셜 러닝, 스마트 러닝에 이르기까지 다양한 방식으로 발전 하고 있다. 빠르게 변화하는 교육환경 속에서 우리가 지금 해야 하는 것은 기술의 발전이 가져다준 미래지향적인 교육 패러다임의 방향을 알고, 교육 현장에 적용하는 것이다. 스마트 시대에 적합한 학습환경을 마련하기 위해서는 이러닝의 주요 학습 환경 구성요소인 학습관리시스템(LMS: Learning Management Systems)의 변화가 매우 중요한 역할을 담당한다. 국내 외 이러닝 분야의 표준은 빠르게 신규 버전이 개발되고 새로운 영역의 표준들이 등장하고 있다. 본 논문에서는 디지털 콘텐츠 및 출판의 융합모델에 대한 표준으로 급부상중인 IMS의 Common Cartridge를 기반으로 하는 수준별 오답분석 시스템을 설계하였다.

These days, computer system has been introduced for work in most areas, including manufacturing, medical service, education, logistics, and other services. To increase work efficiency, mobile system has been more applied. However, on the basis of Android applications, it is hard for laypersons who have no enough knowledge of Android, or computer team members in general firms to develop mobile App. As a result, work efficiency comes to low. Therefore, this study designed and developed the mobile application for anthropometry data input of medical checkup with the use of App Inventor. As shown in the designed and developed mobile application, it is expected to develop a work process mobile App, it is expected to develop a work process mobile App easily and quickly with the use of App Inventor and to increase work efficiency even though there is not much knowledge of mobile application development.

최근 모바일 기기의 활성화에 따라 M-learning (Mobile learning)이 활성화되고 있다. M-learning을 기반으로 한 코스웨어나 모듈 설계 시 학습자의 적극적 참여와 의미 있는 상호작용의 기회 제공과 실제적 환경에서의 교육활동을 지원하는 것에 초점을 맞추어야 한다. 근접발달영역이론 (Zone of Proximal Development : ZPD)이란 독자적으로 문제를 해결함으로써 결정되는 실제적 발달수준과 성인의 안내나 보다 능력 있는 또래들과 협동하여 문제를 해결함으로써 결정되는 잠재적 발달수준간의 거리이다. 한편, 스캐폴딩은 학습자의 근접발달영역을 변화시키며, 학습자가 스스로 학습할 수 있도록 도와주는 구체적인 방식이라 할 수 있다. 또한 스캐폴딩 (Scaffolding)은 학습자가 구조를 조직하고 새로운 지식을 구성하도록 교수자 또는 촉진자가 도와주면서 교수자와 학습자간에 상호작용하는 과정이다. 본 연구에서는 근접발달영역이론을 이용하여 모바일로 교사가 학습자에게 스캐폴딩을 제공하는 수업모형을 제안한다. 본 모형의 특징은 다음과 같다. 첫째, 문제해결을 위한 스캐폴딩만이 아니라 문제 해결 후 격려 스캐폴딩을 제공하여 학습력 강화가 이뤄지도록 하였다. 둘째, 교사와 학습자 사이에 다양한 스캐폴딩을 제공하여 상호작용을 강화하였다. 셋째, 자신에게 맞는 개별학습, 반복 학습이 가능하고 자기 주도적 학습이 강화되도록 하였다.

The university museum is working to discover, research, and exhibit cultural artifacts as well as use them as resources of education and academic researches as one of the important organizations of the university. Current, however, university museums have the low-level usability caused by the reduction of financial and administrative supports of the university. One approach to solve this problem may be the design of mobile docent app for improving the accessibility of the museum. The app enables users get artifacts and education programs without the restriction and learn artifact-related knowledge easily. In this paper, we design and implement a new mobile docent app according to the analysis of content of the Chosun university museum as a real case study. In addition, we evaluate the functionality and usability of the proposed app by affordance-based questionnaire.

Just as noted in some studies related to U-learning based on the ubiquitous technology, it is required to reflect both factors of the environments and contexts of learners on the teaching and learning strategy. For this, the current paper suggests an inquiry learning method and a mobile learning support device for the inquiry learning. Since the inquiry learning is operating on the basis of the contents that learners themselves experience in the fields, it naturally leads them to position in the learning environments and contexts. In this study some curricula are adopted and transformed for the inquiry learning, and the developed mobile device for the learning has a guide function, so that learners might follow the inquiry learning process. In addition, it is possible to reuse the acquired learning data by storing them on a remote learning sever, which may support the inquiry learning of students. These system and device are applied in the teaching sites of schools and, consequently, it is found that in regard with the learning interest and academic performance of students there is an advanced result, being statistically significant.

In this paper, we propose an intelligent vocabulary recommendation agent that automatically provides vocabulary corresponding to game-based learners' needs and requirements in the mobile education augmented reality game environment. The proposed agent reflects the characteristics of mobile technology and augmented reality technology as much as possible. In addition, this agent includes a vocabulary reasoning module, a single game vocabulary recommendation module, a battle game vocabulary recommendation module, a learning vocabulary list Module, and a thesaurus module. As a result, game-based learners' are generally satisfied. The precision of context vocabulary reasoning and thesaurus is 4.01 and 4.11, respectively, which shows that vocabulary related to situation of game-based learner is extracted. However, In the case of satisfaction, battle game vocabulary(3.86) is relatively low compared to single game vocabulary(3.94) because it recommends vocabulary that can be used jointly among recommendation vocabulary of individual learners.

In this paper, a mobile quiz system using SMS has been developed, which can be conveniently used on the spot of education. The system immediately not only provides each individual student with the results of his/her quizzes but also a instructor with the statistics of the results by SMS. Field tests of the quiz system have shown that it can be effectively used as a good teaching tool for teachers getting immediate feedback from participants in the lecture and adjusting teaching level as well as for inducing more interest in learning from participants and raising their concentration on the class.

As ubiquitous computing is evolving, RFID/USN technology is largely applied to various fields. Although there has been much research on the improvement of educational environment using RFID/USN technology, there has been little research on the learning improvement using it. So, in this paper, we used RFID/USN technology to find out the location and situation of students for Chinese situation learning system. We developed a mobile RFID middleware for Chinese situation learning system reflecting Chinese characteristics compared with English on PDA. In USN environment, we designed a USN system, which gets the situation information through a sensor network with sensors and sends them for helping learners study in situation learning. We took a pilot test to a small group for the analysis of the system.
