This paper propose a clustering algorithm for mobile nodes that possible more efficient clustering using context-aware attribute information in adaptive learning. In typically, the data will be provided to classify interrelationships within cluster properties. If a new properties are treated as contaminated information in comparative clustering, it can be treated as contaminated properties in comparison clustering. In this paper, To solve this problems in this paper, we have new present a context-awareness learning based model that can analyzes the clustering attributed parameters from the node properties using accumulated information properties.

The pilot's role is absolutely critical to the safety of an airline. It can be predicted that there is a difference in the acquisition of pilot competency required in actual flight at the initial flight training stage. In this study, the progress and effects of education and training for each background are analyzed, and differentiated competency-based training is to be studied. By sampling a sample of civil airline pilots, we are trying to determine whether there is a difference in the results of the regular proficiency check among the eight competencies defined by ICAO according to military and civil backgrounds. Accordingly, an independent t-test was conducted to test the average difference between the two groups, from the military and civilian origin, to confirm the average difference in the piloting competency between the groups. Based on these results, it will be helpful to design future training courses.

In this study, we tried to find a way to improve the pedagogical decision-making practices related to the presentation order of 'large number' and 'small number' in problem situations of subtraction of the natural number. For this purpose, the elementary school teachers' perception about problem situations in real-life context of subtraction of natural numbers was investigated, and the collected data were analyzed qualitatively and quantitatively to identify teachers' pedagogical perceptions. As a result of this study, it was confirmed the need for consideration on how to set up a problem situations in real-life context of subtraction so that students can develop their ability to solve various types of problems. To this end, not only in a problem situation of subtraction where you have to think of 'large number' first and 'small number' later, but also about the introduction of problem situations in real-life context of subtraction in which you think about 'small number' first and 'large number' later, which often appears in real-life. You will need to recognize the need. And you should have a pedagogical view on this. The results of this study will be able to contribute to the preparation of pedagogical method that can expand the understanding of various problem situations where subtraction is applied from the lower grades of elementary school.

최근 인터넷 기술의 급속한 발전에 따라 교육 현장에서도 교과의 특성이나 상황에 따라 학생들이 작성한 과제를 홈페이지 자료실, E-mail, FTP 등을 이용하여 제출 받고 평가하는 사례가 늘어나고 있다. 이는 과제물의 공개, 과제물 수용 용량의 부족 현상, 평가에 따르는 불편함, 과제물을 또 다른 정보로 재환용 할 수 없는 문제 등을 발생시킨다. 본 논문에서는 XML에 기반을 둔 과제 관리 시스템을 설계하고 구현함으로써 학생은 자신에게 주어진 과제를 인한 후 과제가 공개되는 일없이 정해진 기간 내에만 제출할 있고, 교사는 제출되어진 과제물을 효율적으로 평가한 수 있어 많은 시간과 노력을 줄일 수 있도록 하였으며, 제출된 과제물들은 유용한 정보로 재 사용할 수 있도록 하였다.

본 논문의 목적은 두 가지이다: 첫째, 구성주의와 사회문화주의의 통합적인 이해를 통해 수학 교사 교육에서 사용할 수 있는 이론적인 잠재성을 토의한다. 둘째, 비고츠키의 사회문화주의에 대한 토의가 그리 많지 않은 상황에서 사회문화주의자들의 주장을 교사교육적 관점에서 설명한다. 학습을 개인적 타원에서 설명하는 구성주의와 학습을 사회적 차원에서 설명하는 사회문화주의는 그 발생 원리상 큰 차이점을 갖는다. 본 논문에서는 이러한 차이점에 대한 논란보다는 어떻게 이 두 가지 이론이 학생들의 수학 학습에서 교사의 역할에 대한 재조명과 이론적 지지 기반을 제공할 수 있는 가능성을 갖는지 다루고 있다.

본 논문은 제조 산업 현장에서의 업무 능력 향상을 위한 XR 교육훈련 콘텐츠의 가변적 시나리오를 제안한다. 가변적 시나리오를 적용한 XR 교육훈련 콘텐츠는 교육훈련 관리자가 자유롭게 시나리오를 가감할 수 있어 동일한 콘텐츠 내에서 다양한 시나리오로 콘텐츠를 구성할 수 있는 특징을 가진다. 이는 기존 하나의 시나리오로 반복되는 교육훈련의 한계를 해결할 수 있으며, 현장에서 발생할 수 있는 돌발적 상황 및 변화되는 업무 프로세스를 효과적으로 진행할 수 있을 것이다.

This research suggests scenarios of learning in real life contexts with smart devices and provides user interface prototypes to show their characteristics more effectively. For this, literature review was conducted to understand the strength and limitations of current learning in which real life contexts are used. Then, the characteristics of smart devices as a support tool of learning service was reviewed. With such understand, a user research was executed to establish 10 design guidelines for learning service in real life contexts. Finally, this paper suggested two scenarios that shows learning in real life contexts as case studies and their detailed user interface protypes.

The university e-learning classes give a major focused on practical training in the art and design field are opened such as theory classes. The cyber universities that fully gives on-line classes even open as theory classes. They speak about difficulty and limitation of operating cyber class with practice. So, many of them organize off-line special lecture at the classroom in weekend. In the reason of studying that has the constraints of time and space, the student wastage rates in cyber universities are going higher. This research focused on giving an efficient e-learning practice environment in college e-learning courses, and operated scholastic achievement test between the augmented reality(AR) based practice education and the existing classroom based practice education. The subjects of study were totally 84 people who are the freshmen of the design department in the two-year diploma course college. They were divided 3 groups which one was treated AR based practice e-learning and two others groups were existing classroom based practice. Each of the group took the same treated lecture during 7 weeks. The first of the outcome was the AR based practice e-learning was more effective than existing classroom based practice on the side of scholastic achievement. The second, the AR based practice e-learning aroused increasing in the interest in class on the side of attribute factors. The third, the AR based practice e-learning group made higher level of studying immersion than others. In consideration of this experiment was processed in the regular college academic course, the finding by this research shows AR based major practice e-learning is an alternative lecturing strategy what can be supplemented existing classroom based academic teaching methods.

History and philosophy of science has been consistently emphasized in science education for various purposes. In accordance with the introduction of the 2015 revised curriculum, history of science could be implemented for the curriculum; designing well-organized learning strategies is required. This study examines the case of undergraduate students who solved the convergence problem based on history and philosophy of science in the problem-based learning program. In particular, this study tries to find strategies for integrated education by comparing the problem structuring process and the meaning of problem solving experience of science/engineering and humanities/social sciences students. Participants were three students majoring in science/engineering and humanities/social sciences. Participants constructed and solved their own convergence problems by integrating the domains that were familiar to them into history and philosophy of science. While the process of structuring the problems and the use of history and philosophy of science were similar, there were differences between the science/engineering and humanities/social sciences students' point of view on history and philosophy of science and the other domain which they choose. Moreover, there were differences between the two group's meanings of problem solving experience. Finally, based on the results of this study, history and philosophy in science provided some implications in the context of science education and integrated education.
