This is the study of contents framework of information devices education for the computer science education in elementary school. In this study, we organize and suggest the educational contents of the information device education and its achievement for computer science education in elementary. For this, the educational contents of information device education in Korea and other countries were investigated. Then we selected some contents of information device education that can be applied to the computer science education. With this contents framework of information devices education for the computer science education in elementary school were made. This study will contribute to the curriculum development of computer science at the national level.

The purpose of this study was to explore the effects of science classes on positive science experiences and science learner identity, using smart devices in a future school: C middle school. We conducted a paired t test at the beginning and end of the first school year with first-grade students at the future school to investigate positive experiences with science (Shin et al., 2017). Additionally, first and second-grade students in future schools using smart devices wrote and drew their own depictions in science classes to explore science learner identity, based on a modified analytical framework (Luehmann, 2009). The results show that significant effects on science-related career aspirations, self-concepts, and academic emotions were produced by science classes using smart devices. Science classes using smart devices helped students improve their level of agency and activity, solve problems with immediate and sufficient feedback, and experience meaningful perceptions of the nature of science. On the other hand, if students were immature in terms of their use of smart devices, they felt pressured to participate in the classes. The results of this study can be used as a foundation for designing various classroom contexts for the use of smart devices.

모바일 클라우드란 클라우드 컴퓨팅을 모바일 기기의 영역까지 확장시킨 것으로 모바일 기기의 특수성을 고려하여 클라우드 서비스를 제공하는 서비스를 말한다. 모바일 기기의 특수성에는 하드웨어 제한, 이동성, 모바일 환경에 최적화된 응용 등이 있고, 본 연구에서는 모바일 기기의 특수성을 반영하기 위해서 기기와 클라우드를 중계하는 브로커와 그 브로커에서의 퍼지 모델을 이용한 자원 프로바저닝 방법을 다룬다.

나는 미국에서 박사학위를 마친 후 연구대상이 되는 시료를 직접 만드는 것은 물론 만든 시료의 특성을 밝혀내기 위한 기기까지도 상품화된 기기를 모방하는 등 직접 만들어 사용했다. 귀국 후에도 여러 차례 재료를 만드는 작업을 했지만 실패와 좌절 끝에 개선된 전기로 MCT단결정 덩어리를 제작하는데 성공하게 되었다. 연구실 작업이 고뇌의 연속이라고 하지만 돌이켜 보건대 그것은 바로 예술이요, 예술적 작품인 것임을 알게 되었다.

In this study, we analyzed the teaching practices of science teachers using smart technologies and investigated their difficulties in implementing smart education and their educational needs. We also studied their opinions on the application of smart technologies in science education. The participants were seven science teachers who participated in the smart education study group of a science teacher association in Seoul. We elaborated on the characteristics of smart education in science education during comprehensive analyses of instructional materials used in science classes and the initial interviews. We then analyzed the second interviews by categorizing their responses inductively. All the science teachers used the 'instant access as needed', but their interactions, simply answering students' questions, were found to be at a low level. They did not effectively use the 'collaborative interaction with SNS or wiki-based service' for the support for interactive learning. While most collected learning results of their students and provided feedback in the aspect of 'individualization according to leaner level', they were not aware of 'context, situation, and location of learners' in smart education. While all the teachers extended learning opportunities by using learning resources widely in smart education, most were not aware of 'support for self-directed learning'. Most teachers believed that smart education should be developed to help students learn interactively and in a self-directed manner. They also provided many opinions on teacher training programs and environmental support for smart education. Based on the results, some considerations for implementing smart education in science instructions effectively are discussed.

This study purported to study the uses of information and communication technology (ICT) tools in their daily life among the undergraduate and graduate students majoring science and engineering. It also examined the purposes of the uses of the major ICT tools, the differences in their information technology uses between graduate and undergraduate students. The data were collected from 83 undergraduate and graduate students from four universities using content analysis of an observational logs and a survey questionnaire. The observational logs were collected using an instant message application available on a smart phone. Study results revealed desktop computers, laptop computers, and smart phones as the three most heavily used ICT tools among the participants and typical situations students use each of the three tools. There were also sharp distinctions between graduate and undergraduate students in their selection of the tools, and distinctions between work and non-work situations. The findings of this study can be used to redesign information services and systems for the scientists and engineers in the next generation.

The purpose of this study is to investigate the influences of small group learning using smart devices in science classes on students' achievement, learning motivation, attitude toward science lessons, and perception of small group learning using smart devices. Four 11th-grade classes (N=133) at a coed high school in Seoul were randomly assigned to a control group and a treatment group. The intervention of small group learning using smart devices emphasized collaborative writing on activity sheet. The students were taught about acid, base, and neutralization reaction for six class periods. After the instructions, an achievement test, the learning motivation test, the attitude toward science lessons test, and a questionnaire on the perception of small group learning using smart devices were administered. Two-way ANCOVA results revealed that there was a statistically significant interaction effect by their previous chemistry achievement in the achievement test scores. Only low-level students in small group learning using smart devices significantly improved their achievement probably by having the opportunities to get help from high-level students. The adjusted means of the treatment group were significantly higher than those of the control group in learning motivation and attitude toward science lessons. Students' perceptions of small group learning using smart devices tended to be positive. Educational implications of this study are discussed.
