최근 지식정보화 시대의 집단지성기반 교육 패러다임 변화는 큰 이슈로 떠오르고 있다. 특히 융합적 학문을 근원으로 창의성 계발과 아이디어를 중요시하고 있으며, 창조적 교육방식을 지향하고 있다. 그러나 다양한 영역에 지식전문가들과 학습자들 간에 지식을 공유하기 위한 플랫폼 공간이 제대로 제공되고 있지 못하며, 단순한 컨텐츠 제공을 목적으로 이러닝 서비스가 일부 제공되고 있는 것이 현실이다. 따라서 본 논문에서는 집단지성을 기반으로 지능형 튜터링 에이전트 시스템 설계를 제안하고, 새로운 에이전트(Agent) 개념을 통해 지식인들과 학습자들 간에 지식을 공유할 수 있을 뿐만 아니라 새로운 지식을 창출하고, 관리 및 유통할 수 있는 구조를 연구하였다. 또한 사용자들로부터 발생하는 데이터와 정보들을 자동 분석하여 지능적으로 학습상황에 대처할 수 있도록 설계하였으며, 튜터(Tutor)와 튜티(Tutee)간에 협력적인 학습 생태계가 형성될 수 있도록 하였다. 따라서 본 연구의 결과를 기반으로 미래 스마트 학습 플랫폼 발전에 많은 도움이 되길 기대한다.

STEAM and S / W education in public education are effective in fostering talented people and the talents of the 4th industrial revolution era. It is necessary to expand the teachers for this purpose, to find out and apply various learning materials, and to improve education environment for fusion talent education. An open learning platform is effective in reducing private education costs and supplementing public education. Especially, it is useful for flip learning combined with classroom (off-line). In this case, teacher's role can be transformed into active teaching activities and research activities, which can speed up normalization of public education and reduce private education.In particular, the core functions of the MOOC platform for elementary education are 'creative instructional design and contents development function', 'digital teaching and learning curation', 'big data based learner customization', 'learning participation' flip learning and social Learning function.Through this study, it is expected that discussion on the introduction of MOOC for career and admission education for adolescents including elementary education will be established and the Korean youth MOOC platform will be developed and developed as a global advanced model of education democratization.

In recent years, a variety of learning content construction utilizing the smart phone is coming. In this paper, we investigate on overall trends and movements in e-learning performance at University. And system developed a e-learning platform consisting of smart phone portal, learning management system(LMS), and learning content management system(LCMS). Throughout the experiment, each of the components of the e-learning were implemented. LMS was implemented more efficiently using a user profile evaluation system for qualification.

본 논문은 엣지컴퓨팅 환경에서 딥러닝기반 추천모델을 이용한 지능형 디지털 사이니지 플랫폼을 제안한다. 제안하는 플랫폼은 서버와 엣지로 구성되어 있다. 서버는 데이터를 관리하고, 광고추천 모델을 학습시키며, 엣지는 학습된 광고추천 모델을 이용하여 실시간으로 광고될 상품을 결정한다. 광고추천 모델은 상품을 선별하는 단계와 구매확률을 예측하는 단계로 구성되어 있다. 선별단계에서는 DNN에 벡터화된 사용자 기본정보와 상품 메타데이터를 입력하여 구매할 만한 상품을 도출한다. 최종적으로 군집의 예측된 구매확률을 이용하여 가장 적합한 광고를 선정한다. 제안하는 시스템은 서버와 통신하지 않고 엣지에서 학습된 모델로 광고를 결정한다. 이를 다수의 사용자에게 즉각적인 반응을 필요로 하는 디지털 사이니지에 적용했다.

Not only learners majoring in computer science, but also non-engineered learners want to implement their ideas as apps through real-life problems. In response, first-year university students with little experience in creating apps studied how to develop mobile platform apps to improve computing thinking skills. We applied the teaching and learning procedures of the Discovery-Design-Development among the software teaching and learning models, and used Android Studio Unified Development Environment (IDE) as a development tool to design mobile platform app development projects and assess whether they helped improve computing thinking skills. The application of the designed teaching and learning method found that the project output was implemented as an app through emulator, which gave students high interest in class and satisfaction, and was effective in improving their computing thinking ability.

Large-scale online platforms such as MOOCs-Massive Open Online Courses, which provide a variety of educational contents, have provided a learning environment that allows students to freely access and learn anytime and anywhere. Currently, the proportion of online lectures and home-based learning is increasing, and portfolio or experience-based learning such as bootcamp, field activities, and team project-based group learning are also being actively carried out for educational outcomes. At present, interest in nano or microdegree focused on core technology in units of hours or credits is increasing significantly because such strategic intensive education enables effective learning in terms of continuity and efficiency of education. In an era of large changes in job market due to the reorganization of the industrial structure by new technologies, intensive education in specialized new technology fields such as smart mobility, big data, and artificial intelligence is much more conducive to finding a job. With this reason it is attracting attention as an alternative to lifelong learning are receiving In this paper we propose an educational platform that can efficiently and effectively support the purpose learning for the personalized microdegree education in the online learning era.

The purpose of this study is to analyze the current situation of EduTech, which is proposed as a way to build a flexible learning environment regardless of time and place according to the use of digital technology in mathematics subjects. The process of designing classes to use the EduTech platform, which is still in the development introduction stage, in public education is still difficult, and research to observe its effects and characteristics is also in its early stages. However, in the stage of preparing for future education, it is a meaningful process to grasp the current situation and point out the direction in preparation for the future in which EduTech will be actively applied to education. Accordingly, the current situation and utilization trends of EduTech at home and abroad were confirmed, and the functions and roles of EduTech platforms used in mathematics were analyzed. As a result of the analysis, the EduTech platform was pursuing learners' self-directed learning by constructing its functions so that they could be useful for individual learning of learners in hierarchical mathematics education. In addition, we have confirmed that the platform is evolving to be useful for teachers' work reduction, suitable activities, and evaluations learning management. Therefore, it is necessary to implement instructional design and individual customized learning support measures for students that can efficiently utilize these platforms in the future.

According to the participants, the current K-MOOC (Korean Massive Open Online Course) has a few problems, such as too few courses, low content quality, and useless learner management system compared to MOOCs abroad. These problems caused diminished learner motivation. Consequently, the K-MOOC service has recorded a low course completion rate despite high expenses spent to develop the contents and thus requires remedies to fix the issues. This study drew research subjects from a pool of college and graduate students representing the primary users of the K-MOOC. This study limited the research scope to the four categories: motivation, learning experience, recognition, and performance of the Biggs' 3P Learning System Model. Based on the literature review, ten variables were selected and explored how the subjects perceived four categories using the survey questionnaire. This study also examined the relationship between ten variables and generated suggestions for the instructors, course managers, and platform developers to make the K-MOOC better.
