In this study, an simulation app was developed as one of the methods to help learners better understand the eight process scheduling policies of multi-programming. In learning, an app in the form of a simulation should provide a realistic environment and allow learners to practice. To do this, the needs of the learners were investigated and analyzed, and the purpose was set, designed, and programmed based on the learners' understanding. And it was shown that the apps as a tool to simulate the created eight scheduling policies are performing well. In particular, it was shown that the problem of not having a step-by-step various diagram and explanation for step-by-step various inputs, which is a limitation of paper textbooks, can be solved using these tools.

광범위한 스마트폰의 보급으로 인해 관련 APP 시장 또한 급격하게 증가하고 있다. 많은 APP이 개발되고 있지만 대부분 특정 분야에 집중되어 있으며 교육용 APP이 시장에서 차지하고 있는 비율은 극히 낮다. 시장 비율이 낮은 이유는 기존 출시된 대다수의 교육용 APP이 가지는 두 문제점 때문이다. 첫 번째는 동일 콘텐츠의 반복학습으로 인해 재사용 빈도가 많이 낮고 자기주도학습 능력을 이끌어 낼 수 없다는 점이며 두 번째는 문제 제공 및 정답 확인의 단순 구조로 되어 있어 사용자가 자신의 수준 및 취약 부분을 분석하기 힘들다는 점이다. 본 논문은 스마트폰 환경에서 앞서 언급한 두 가지 문제점을 해결하기 위해 시스템 구조 변경 없이 콘텐츠 변경이 가능하며 사용자의 수준을 파악할 수 있는 기능을 가진 사용자 맞춤 교육을 위한 교육용 앱 설계에 대하여 제안한다.

Recently youth problems such as school violence and bullying are becoming increasingly lower age. In order to overcome this situation highlights the importance of education and the emotions, which in analyzing the existing mobile app, only the most fun-oriented approach has been made and the information presented. It focuses on the emotion awareness and empathy abilities of learners diagnosis, training, application can be made at the level of educational mobile app prototype was developed. First, self-understanding, self-expression, others-understanding, and empathy of emotional competency derived from review of emotional awareness skills training programs. Second, by analyzing the existing emotion recognition app macro-principles and micro-strategy of mobile app's designs were derived. Third, accordi was conducted on prototype of storyboard and app the completed prototype was completed. The proposed app is a fun and learning by doing, also Depending on students' level of performance can be customized. The proposed mobile app is efficient and effective, engaging learning space as a systematic training in the diagnosis and the emotions through the elementary students will be able to improve emotional awaeness competency.

The aims of this paper were to review the usable possibility of the educational App Inventor Program in the field of programming education and to develop programming teaching materials that can overcome limitations of the established programming instruction. The study showed that the learners' motivations were strengthened through smart device programs. Containing the elements of STEAM, the teaching materials were developed for the logical and systematic learning that deals with elementary students' real-life situations, and that helps children follow the procedures of software development. By introducing the Waterfall Model to the process of programming, students are able to follow the software developers' thinking process. In addition, beyond the simplistic programming language and simply acquiring related knowledge, the App Inventor programming was designed to enhance students' higher-order thinking skills such as creativity, problem solving ability, collaborative thinking, and so forth.

The aim of this study is to suggest development guidelines of educational smart application for the students with development disability based on Universal Design for Learning(UDL). The basic guideline set were organized by analyzing UDL studies on different media. The totally 35 preliminary guidelines which consist of 14 items of contents presentation, 12 items of education strategy and 9 items of education engagement were settled through review of smart contents expert developer and professors in special education. Based on the preliminary guideline, a survey was conducted to determine effective guidelines among end users which consist of the teachers who educate students with disability, parents with disabled children and professors in special education major. 3 categories and 20 guidelines are presented by analyzing survey result through excluding items whose importance factor were lower than average of importance.

In this paper, smart devices using a 4 to 6 years old, infants and parents to a user layer of training and with games or studying infants by integrating them. Not losing interest and concentration, Mobile infants to learning to learn Korean, English, the estimated budget. design the app tainer. For parents of infants and a variety of media concentration and learning Korean, English, English word cards that can increase the interest of the design and, to find a picture Memory game, had provided games are various kinds such as learning to do puzzles. Also, infants and tries to help study a visual learning and auditory learning at the same time can be achieved by mothers of children is much more conveniently. Learning to guide implementation to maximize the availability, convenience and mobility.

The purpose of this study was to investigate the middle school students' perception and their learning satisfaction in SMART learning based science instruction. Three types of modules on the solar system and lunar phases unit at the middle school level were developed and lessons on each module were taught to 207 student participants. All participants were provided with tabletPC(iPad2) with iOS5 installed, and using astronomy app Solar Walk, mirroring function, QR code, and Google Presentation, the lessons were carried out both in classroom and at home. The instrument for assessing students' perception on the SMART learning-based instruction was developed based on 4 factors including Self-directed, Motivation, Adaptiveness, and Technology Embedded, with a Likert scale from 1-5 on 20 items. The learning satisfaction survey instrument was originally from Keller's work (1987), and its test items were adapted and modified. To reveal the perception and learning satisfaction about SMART learning-based science lessons, the participants were comparatively analyzed by gender and science achievement levels. Results indicated that male students showed positive perception for the SMART learning-based instruction. Group with higher science achievement scores showed more positive perception of the SMART learning-based instruction in terms of Self-directed and Motivation factor. Also, the learning satisfaction of male students was higher than female students and group with higher academic ability more satisfied with the SMART learning-based instruction than the low group. The results provide implications for future development of programs and help set a direction of increasing the use of a SMART learning-based science in school.
