웹 기반 프로젝트학습은 학생들 스스로 웹에서 자신들의 제작물을 만들면서 자신의 기능과 지식을 실제로 적용하는 과정과 학습경험을 모두 의미한다. 그러므로 학습자들의 다양하고 폭넓은 학습활동이 기대된다. 본 연구에서 설계한 프로젝트 학습 시스템은 수시로 교사와 전문가의 도움도 받고 다른 팀의 동료 학생들로부터 평가를 받으면서 아동의 관심과 흥미, 주제 중심, 활동 중심, 문제 중심의 프로젝트 활동을 할 수 있도록 한다. 그리고 이들 웹 상에서 구현함으로써 학습자 중심의 공동 프로젝트 학습이 되도록 한다.

The paper describes aspects regarding an E-learning approach of resonant ac inverters. The learning process is based on "Learning by Doing" paradigm supported by several learning tools: electronic course materials, interactive simulation, laboratory plants and real experiments accessed by Web Publishing Tools under LabVIEW. Built on LabVIEW and accompanied by a robust, flexible and versatile hardware, the experiment allows a comprehensive study by remote controlling and performing real measurements on the inverters. The study is offered in a gradual manner, according to the Leonardo da Vinci project EDIPE ($\b{E}$-learning $\b{D}$istance $\b{I}$nteractive $\b{P}$ractical $\b{E}$ducation) philosophy: theoretical aspects followed by simulations, while in the end the real experiments are investigated. Studying and experimenting access is opened for 24 hours a day, 7 days a week under the Moodle booking system.

In this paper, we describe a case study of a new lab. project that improves efficiency for education and interest on learning in image processing and pattern recognition related subjects by using LEGO Mindstorms. In addition we verify the validity with analysis of the practical application. LEGO Mindstorms is already used in many educational institution of several countries since about 10 years ago and various case studies have been published. The use of LEGO Mindstorms is generally positive but the negative comments about this exist. The main cause of negative opinion is from unpredictability. The unpredictability from mainly analog characteristics of robot can degrade the effective learning. The describing lab. project suppresses occurrence of unpredictability by minimizing dependence on robots. Students can concentrate on learning the related algorithms by minimizing the learning content and further consideration.

Recently, many attentions have been paid to conducting convergence research across diverse disciplines. Along with this convergence era, an IT-based multi-disciplinary convergence project, called EDISON (EDucation-research Integrated Simulation On the Net), has been launched to support the studies of researchers engaged in several computational science and engineering (CSE) fields and to boost learning motivations of CSE students. Since 2011, we have been successfully carrying out the EDISON project. EDISON as a cyber-learning platform enables CSE researchers to share their own high-performance computing (HPC) simulation softwares developed to solve their research problems accompanying large-scale computation and I/O and users to run the softwares with little constraints on the web. Also, the EDISON platform has been utilized as lecture material by many universities in Korea. This article introduces the construction and service statistics of this EDISON platform. Specifically, we explicate several distinctions between EDISON and existing other HPC service platforms and discuss a three-layered technical architecture of the EDISON platform. We then present the up-to-date service statistics of EDISON over the past four years. Finally, we conclude this article and describe future plans.

컴퓨터의 발달과 정보통신의 확대로 인하여 사회 각 분야에 대한 변화와 함께 교육환경에도 많은 변화가 이루인지고 있다. 학습자 능력 중심의 교육으로부터 사용자 중심적인 교육의 필요성과 학습자간의 그룹 활동의 의미가 점차 증대되고 있다. 본 논문은 면대면의 학습체계로부터 산업체의 업무처리 체계를 실현 목표로 한 프로젝트 교육 학습체계를 제시한다. 본 논문에서는 가상적인 작업 공간을 공유하고 프로젝트의 주판자 적인 입장에서 교육을 진행하므로 기존의 프로젝트 교육과 달리 사용자 중심의 비교 학습 및 패턴 설계의 장점을 극대화 시켜 인터넷/인트라넷상에서 실행되는 프로젝트 교육의 설계와 구현 방법에 관해 논한다.

The KMTNet Supernovae Project utilizes the large $2^{\circ}{\times}2^{\circ}$ field of view of the three KMTNet telescopes to search and monitor supernovae, especially early ones, and other optical transients. A key component of the project is to build a data pipeline with a descent latency and an early alerting system that can handle the large volume of the data in an efficient and a prompt way, while minimizing false alarms, which casts a significant challenge to the software development. Here we present the current status of their development. The pipeline utilizes a difference image analysis technique to discover candidate transient sources after making correction of image distortion. In the early phase of the program, final selection of transient sources from candidates will mainly rely on multi-filter, multi-epoch and multi-site screening as well as human inspection, and an interactive web-based system is being developed for this purpose. Eventually, machine learning algorithms, based on the training set collected in the early phase, will be used to select true transient sources from candidates.

This study aims to investigate better predictors, among learner participation and interaction, for collective self-efficacy and achievement in a web-based collaborative learning environment. Interaction requires communication among two or more learners, while participation does not. In this study, interaction was measured by in-degree centrality and out-degree centrality based on the social network analysis perspective. Multiple regression analysis results from 53 college students who performed team project via online showed that in-degree centrality predicted collective self-efficacy and out-degree centrality predicted achievement, while participation was not a significant predictor.

The purposes of this study are to investigate students' attitudes regarding group projects and to suggest an effective way to promote collaborative learning using Wiki. This study employed a survey questionnaire, which was distributed to students enrolled in classes provided by a university in Seoul. The result revealed that students preferred individual projects to group projects because various barriers occur in the process of group projects. Students' responses also indicated that rapport among group members influences the success of a group project. In addition, Wiki, as a Web 2.0 tool for group collaboration, was recognized as being useful in terms of promoting openness, modification, and effectiveness. Based on these findings, this study suggests the following for effective collaborative learning: (1) conducting peer- and self-assessments to avoid social loafing, (2) establishing rapport among group members, and (3) using Wiki in an active manner.

However, there is a lack of research on AI education design and competency-based education curriculum as education for business major. The purpose of this study is to design AI education to cultivate competency-oriented AI literacy for business major in universities. Research design, data and methodology: For the design of AI basic education in business major, three expert Delphi surveys were conducted, and a demand analysis and specialization strategy were established, and the reliability of the derived design contents was verified by reflecting the results. Results: As a result, the main competencies for cultivating AI literacy were data literacy, AI understanding and utilization, and the main detailed areas derived from this were data structure understanding and processing, visualization, web scraping, web crawling, public data utilization, and concept of machine learning and application. Conclusions: The educational design content derived through this study is expected to help establish the direction of competency-centered AI education in the future and increase the necessity and value of AI education by utilizing it based on the major field.
