With the popularity of smart phones for mobile learning on the rise, cyber universities in Korea are trying to build a reliable mobile campus infrastructure. Such advances in smart phone technologies have made it increasingly easy for users to stay connected and this heightened interaction through smart phones has educational potential for collaborative learning. Thus, to fulfill its educational potential and ultimately provide optimal learning environments on the smart phones, this study has developed a discussion-based interface prototype for collaborative learning. The proposed interface design was evaluated through cognitive walkthrough of the expert reviewers and its usability improvements were also offered.

The aims of this study are to analyse how smartphone affects (1)self-control and (2)self-directed learning ability of middle-school students, and also affect (3)self-directed learning ability by mediation of self-control. For these aims, this study used Seoul Educational Longitudinal Study panel data which was conducted in 2015, and conducted multi-group comparisons using structural equation modeling analyses. In analysis of smartphone effects, the use of smartphone of students was divided into 'for entertainment' and 'for learning', and also their first time of smartphone use was considered(elementary vs. middle school). Results indicated that while 'smarphone use for entertainment' was related negatively with self-control and self-directed learning ability of students, 'smarphone use for learning' was related positively, regardless of when smartphone was first used. Also, while 'smarphone use for entertainment' was related negatively with self-directed learning ability by mediation of self-control, 'smarphone use for learning' was related positively.

This paper reports on a design and implementation of a Smartphone App providing the SCAMPER method. The SCAMPER method is an efficient method of creativity, which is a way of encouraging uniqueness, promoting change in things, and evoking or triggering new or varied possibilities. The Smartphone users analyzed the effectiveness and shortcomings of the Smartphone App. The results showed that the developed Smartphone App is effective in terms of the value, use, content, and component. The Smartphone App is also efficient to use anywhere, anytime and to express, share, actively communicate with others through the App. In addition, several improvements of the App were suggested for Smartphone users to develope and enhance their creativity by adopting the SCAMPER method.

The interactions between a professor and students are very important in humanities classes A professor could not exchange opinions with students especially in large-scale classes. We have developed a smart phone app. in order to overcome the lirnit of interaction between a professor and students in large-scale classes. The app we have developed in this paper have exploited smart phone's data processing and wireless communication ability. In this paper, we showed that smart phone could be an useful tool for increasing the education effect of large-scale classes.

오늘날 학생들에게 스마트폰은 일상생활에서 빼놓을 수 없는 친숙한 기기이지만 단순한 오락 위주의 활용에 그치는 경우가 대부분이다. 스마트폰을 손안의 작은 컴퓨터라는 관점에서 본다면 이는 더욱더 안타까운 실정이다. 왜냐하면 스마트폰은 그 동안 물리적 현실적 제약조건을 벗어나 다양한 교육활동을 가능하게 할 수 있는 교육 도구로써도 의미가 있기 때문이다. 이에 본 연구에서는 앱 인벤터를 활용한 PBL프로그래밍 교육을 연구하고자 한다. 앱 인벤터를 통해 학생들은 실제로 활용가능한 앱을 만들 수 있다는 점은 다른 교육용프로그래밍 언어와 차별화된 점이라 할 수 있다. 이러한 장점을 적극 활용하여 학생들의 흥미와 관심을 지속적으로 유지시키며 프로그래밍 교육을 할 수 있다는 점에서 의미가 있다고 생각한다.

The purpose of this study is to analyze relationship between community participation and smartphone usage level. The study was conducted for 100 people aged 55 or older. We conduct a task-based questionnaire to evaluate smartphone usage level. The levels of smartphone use were reclassified as 0~3 points C level, 4~7 points B level, and 8 points or more A level based on task-based survey score. For data processing, SAS 9.4 was used. As a result, a total of 97 data were included in the result analysis, and 85 smartphone users(87.6%). There was a significant correlation between smartphone usage level and community participation(r=0.22). As a result of using ANOVA, the smartphone usage level and community participation scores showed a significant difference(p=0.04). This study confirmed that there is a difference in community participation by smartphone usage level. Most elderly people showed high smartphone education demand. It is considered necessary to develop educational programs and educational tools to improve educational satisfaction and smartphone usage.

The purpose of this study was to investigate the moderating effects of perceived father's rearing attitudes on the relationship between self-efficacy and smartphone addiction in adolescents. A survey was conducted using a convenient sample drawn from 570 students from eleven junior high school in Seoul. Data were analyzed using SPSS 20.0 program. The results show that 22.4% of students was in the risk of smatphone addiction. High risk of smartphone addiction group use smartphone longer for communication and had more trouble with their parents because of smartphone use. Smartphone addiction showed negative relationship with self-efficacy and affection-rational explanation of perceived father's rearing attitude but had positive relationship with inconsistency-intrusiveness of perceived father's rearing attitude. Furthermore, the result showed the moderating effects of perceived father's rearing attitude on the relationship between self-efficacy and smartphone addiction. Therefore, to prevent smartphone addiction in adolescent, we should try to increase self-efficacy in adolescent as well as to develop educational program to assist parent to understand their children.

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.

This study aims to offer a wide range of practical implications for Smartphone addiction prevention by verifying the effect of mind health as a factor that is influenced by Smartphone addiction, and testing the relationships between Smartphone addiction and mind health with school life adaptation as a mediation effect. For this research, a survey was conducted of 250 elementary school students who use Smartphones. The relationships between Smartphone addiction, mind health and school life adaptation were set as the structural equation model, and they were verified by the mediation effect of school life adaptation. The results showed that school life adaptation turned out to be an entirely mediating variable on the relationship between mind health and Smartphone addiction. The statistical significance of the effect on school life adaptation was verified by the Sobel test. The mediation effect resulted in mind health reducing the occurrence of negative emotion of school life adaptation, and also reinforced decreased Smartphone use.
