기존의 이러닝에서는 교수자가 강의동영상을 통하여 주로 단방향으로 지식을 전달하였다. 이런 문제점을 해결하기 위해 본 연구에서논 실시간 상호작용이 가능한 이러닝시스템인 ECube을 제안하고 구현하였다. 교수자에게는 학습자와 실시간 소통을 위한 실시간 강의기능, 전문가의 도움없이 미디어 제작과 편집이 가능한 동영상삼 저작도구인 EMC(Effective Media Contents) 솔루션을 제공한다. ECube 시스템 안의 EMC 솔루션만으로도 자막, 이미지, 퀴즈, 비디오를 합쳐 통합된 콘텐츠의 제작이 가능하다. 학습자에게는 실시간 강의를 수강하는 동안에 발표수업에 참여할 수 있는 기능을 지원하고 자신의 학습에 관한 학습계획부터 학습성과까지의 내용을 문서화할 수 있는 기능을 제공한다. 이 기능을 활용하여 학습자는 과목별 포트폴리오 작성이 가능하여 자기주도적 학습을 수행할 수 있는 학습환경을 제공한다.

The upcoming 'creativity society' beyond the knowledge information era requires 'knowledge producers' being capable of expressing their own ideas creatively, rather than 'knowledge consumers'. These days, in the computing environment, physical computing tools which support learners' productive activities beyond their simple function of operating computers are emerging. Among them, Raspberry Pi is exemplary. The computing PC worthy $35 is economic and supports implementation of interactive physical system through the H/W and programming control to detect and respond to the analog world. As a fundamental study of educational application of Raspberry Pi at elementary school and Raspberry Pi, this work was to look into characteristics, advantages and disadvantages, and application examples of the computing tool. Also this researcher conducted a survey with teachers in field to investigate the suitability of Raspberry Pi as a tool in the category of 'understanding of information devices and to explore their awareness of Raspberry Pi. As a result, it was analyzed that Raspberry Pi was a learning tool to support about 74% of educational contents and that teachers showed positive replies in all categories of the survey of their awareness.

As information technology has been developed in a rapid way, a lot of users get to be familiar with social media. Accordingly, the possibility of social media for educational use has increased. From the view point of learning, social media help learners make communities of practice that can lead to collective intelligence. In this study, two different types of social media, synchronous and asynchronous, were compared in terms of usage patterns in the e-learning settings of college level. Content analysis has figured out four factors: learning content, tasks and assignments, emotional communications, and chatting. There found to be a statistical differences in the postings in all of the factors except tasks and assignments. In the qualitative interviews, the participants told various usage patterns of synchronous and asynchronous social media. In sum, the learners generally preferred synchronous social media. Rather, asynchronous social media were mainly used for deep thinking and summarizing. Last, suggestions were made to improve educational environments for the learners in the digital and social media age.

This study compares Online SW-based maker education in terms of self-efficacy, learning motivation, and interest after applying differently according to blended learning strategies. First, a SW maker program for blended learning was developed and applied as a live seminar-type class including real-time interactive and a support-providing class consisting of online content and Q&A. As a result of comparing the differences between students according to the two strategies divided into pre- and post- survey, in the self-efficacy part, there was a significant difference in the positive efficacy and the overall part, and in the learning motivation part, the live seminar form was significantly higher in the confidence part. In the interest part, the support-providing form showed a significantly higher average in the instrumental interest and nervous part. In order to maintain the effect of maker activities like existing face-to-face situations in Online learning, it is necessary to increase sharing time between students, an integrated learning environment, and sufficient provision of exploration time and learning materials.

Mathematics is a subject that is closely related to ensuring basic academic abilities. As the importance of basic academic abilities has emerged recently, various policies and programs have been implemented to ensure basic academic abilities in mathematics. In this study, we extracted the programs related to mathematics from the Implementation Plans of the Basic Academic Abilities Guarantee of 17 city and provincial education departments and analyzed the actual status of the programs. We divided the programs into diagnosis and support. Regarding diagnosis, we analyzed what types of diagnostic tools are used, who chooses diagnostic tools, who is diagnosed, and when students are diagnosed. Regarding support, we classified it as in-class, in-school, and out-of-school support, and further analyzed the type of the learning support program and the expertise of the instructor. The results of this study showed that there was room for improvement in the timing of diagnosis and diagnostic expertise. This study also found the problems with the lack of preventive programs, ensuring teacher expertise, and support for dyscalculia. This study is expected to contribute to the implementation of programs to ensure basic academic abilities in mathematics and to promote research on basic academic abilities in mathematics education.

The purpose of this study is to explore the educational needs of learning supporting program on the students' perception of current competencies and important competencies. The data was collected by using the online type (e-mail survey) and the offline type (printed survey) with survey instrument developed by researcher. Survey instrument was composed of 3 categories and 10 competencies. Collected data was analyzed using the SPSS 21.0 for Windows statistical package. And 159 cases were analyzed finally. The paired t-test was conducted to analyze the difference between importance-performance of students' competencies. The educational needs of learning supporting program were calculated by using the Borich's formula. The findings were as follows: The first, 3 categories and 10 competencies were significant difference exists statistically. The second, The high ranks of the educational needs of learning supporting program were 'Major field knowledge', followed by 'Creativity', 'Problem solving ability', 'Global capability', 'Technology capability' in sequence. The results of this study reflected the authentic needs of students will be used a basic data to establish the curriculum for learning supporting program.

This study proposes a mobile Augmented Reality (AR)-based "word card" learning tool for children aged 3 to 5. First, this study suggests a learning structure to improve motivation and immersion of learning, Secondly, it designs and implements the user interface applying the proposed learning structure. Also, it designs a content management tool supporting the production of the content so that instructors can easily manage the contents for various learners. This study is conducted by four steps - reference research, design of "word card" learning content for the learner, design of content management tool for the instructor and the effectiveness verification of the proposed content. The proposed content was designed based on an education content architecture for enhancement of immersion and motivation to study. Moreover, it includes an 'AR content management tool for instructor' designed to easily update AR education content. The class for six children aged 3 to 5 was given to validate the enhancement of immersion to study. Experiment results showed that the proposed content enhanced the study immersion and that special interaction design for early children was necessary.

The AI based intelligent command and control system can automatically analyzes the properties of intricate battlefield information and tactical data. In addition, commanders can receive situation analysis results and battlefield awareness through the system to support decision-making. It is necessary to build a battlefield situation analysis dataset similar to the actual battlefield situation for learning AI in order to provide decision-making support to commanders. In this paper, we explain the next step of the dataset construction method of the existing previous research, 'A Virtual Battlefield Situation Dataset Generation for Battlefield Analysis based on Artificial Intelligence'. We proposed a method to build the dataset required for the final battlefield situation analysis results to support the commander's decision-making and recognize the future battlefield. We developed 'Dataset Generator SW', a software tool to build a learning dataset for battlefield situation analysis, and used the SW tool to perform data labeling. The constructed dataset was input into the Siamese Network model. Then, the output results were inferred to verify the dataset construction method using a post-processing ranking algorithm.
