The purpose of this study is to verify the practical effectiveness of the constructivism education theory in building information modeling (BIM)/integrated project delivery (IPD) collaboration education by determining education methods that are most relevant to collaboration in the interaction process. We propose a BIM training model that enhances students' satisfaction in class and collaboration. We aim to identify interrelationships between BIM collaboration education and constructivism theories, examining constructivism methods in BIM/IPD classes to discern which are the most suitable for improving and enhancing collaboration and the proposed education model.

This paper introduces an online collaboration infrastructure in order to build a nationwide collaboration ecosystem in research and education areas. The proposed infrastructure involves domestic research institutes, education institutions and related commercial service vendors. It also includes various systems and services which can promote their online collaboration. Especially it provides the user authentication framework based on identity federation which facilitates the share of various ICT resources across different organizations, thereby enabling the efficient R&D collaboration. We deploy and validate the user authentication framework of the infrastructure on KREONET.

본 논문에서는 교육용 컨텐츠 추천시스템의 정확도를 향상시키고자 사용자 모델 정보를 활용하여 기존의 협업여과 방법의 유사도 재산을 보완함으로써 추천의 정확도를 향상시키는 방법을 제안하고자 한다. 협업여과방법은 사용자의 평가와 비슷한 선호도를 가지고 다른 사용자의 평가를 기반으로 제품이나 항목을 예측하고 이를 사용자에게 추천한다. 그러나 협업여과방법은 일정 수 이상의 상품이나 항목에 대한 평가가 이루어져야 하며, 사용자의 평가가 적은 경우 희소성으로 인한 평가의 정확도가 낮아지는 단점을 기지고 있다. 본 논문에서는 인구 통계 정보를 이용한 가상 평가 점수를 반영하여 유사도 계산시 희소성을 낮춰 예측의 정확도를 향상시키고자 한다.

Collaborative Filtering is a popular technology in electronic commerce, which adapt the opinions of entire communities to provide interesting products or personalized resources and items. It has been applied to many kinds of electronic commerce domain since Collaborative Filtering has proven an accurate and reliable tool. But educational application remain limited yet. We design collaborative filtering recommendation system using user's ratings in educational contents recommendation. Also We propose a method of similarity compensation using user's information for improvement of recommendation accuracy. The proposed method is more efficient than the traditional collaborative filtering method by experimental comparisons of mean absolute error(MAE) and reciever operating characteristics(ROC) values.

In a rapidly changing society with the Fourth Industrial Revolution, future students should have the skills to utilize and organize high-quality knowledge, not the amount of knowledge. With the launch of the revised curriculum in 2015, the curriculum has been reorganized based on competency and the software education has been seeking capabilities such as 'Cultural computing knowledge', 'Computational thinking', and 'Collaborative problem solving skills'. Therefore, practical collaboration tools and education programs that can be used in the field of education are developed based on Pair Programming, which is a specific collaborative learning strategy to develop cooperative problem solving skill. The educational program using this collaboration tool was developed with a focus on developing computational thinking and collaborative problem solving skills through Pair Programming rather than focusing on learning grammar of programming language and programming techniques. In a educational program, students will be able to use collaborative tools for pair programming and foster collaborative problem-solving skills.

This paper aims to design and implement a collaborative learning system based on the augmented reality. The existing augment reality-based learning systems have just focused on interactivity between a system and learners without consideration of cooperability, thereby leading to an ineffective approach to encouraging an learning system to be more supportive and conducive of and to cooperation among learners. The collaborative learning system is a learning method, with which learners achieve a common objective through critical thinking and cooperative teamwork so as to seek solutions to such fulfillment. This requires positive interdependence, proactive interactions, a sense of responsibility shared by individuals as well as the group, and development of teamwork among learners. Educators and systems assume a critical role in helping the collaborative education be effective. An educator is responsible for defining a project at the outset of learning activities, organizing groups for learners, and providing evaluation criteria applied to a group's project activities. Meanwhile, a system shall support interactions to take place while facilitating learning activities. Furthermore, an educator shall provide a system for managing and evaluating activities involving interactions among learners. This paper suggests and embodies a collaborative learning system based on the augmented reality with consideration of the aforementioned collaborative education.

인터넷을 통한 교육이 활발해지면서 강좌의 진행을 보다 효과적으로 관리하고 운영할 수 있는 시스템에 대한 요구가 증가하게 되었다. 특히, 실험 및 공동과제 수업과 같은 강좌의 경우 사용자들 사이의 상호 의견 교환 및 자료의 공유를 용이하게 지원해주는 협업 기능이 제공되는 것이 바랑직하다. 본 논문에서는 학습자와 학습자. 교육자와 교육자. 그리고 교육자와 학습자 간의 다양한 의사교환 방법과 협업 기능을 제공하는 협업지원 강좌 관리시스템을 설계하였다. 본 논문에서 설계된 시스템은 웹상의 가상공간인 개인작업공간, 팀작업공간, 그리고 학습작업공간을 이용하여 강좌 진행 관리 및 중간 결과물에 대한 관리를 효과적으로 지원하고자 한다.

Team-based programming methods are widely applied to solve various difficulties that pre-service teachers experience in the programming lessons. To prepare effective collaboration strategies necessary for them, it is necessary to analyze various collaborative factors that affect learners' programming competencies. Therefore, in this article, a questionnaire survey was conducted by dividing learners' collaboration factors into individual and team competencies, and the relationship between learners' programming competencies was analyzed. As a result of the verification, the program design competency showed significant results in all elements of the learner's personal competency, team techniques such as data sharing skills necessary for collaboration, and team collaboration. It was analyzed that an individual's understanding of learning and team collaboration influenced the program implementation competency. In addition, the group with relatively high team technique showed significant differences in programming competence, interest, and satisfaction. Accordingly, by linking meaningful factors related to individual and team competencies according to the programming process, a collaborative strategy practically necessary for pre-service teachers was suggested.

최근 들어 각국에서는 21세기 핵심역량을 규명하고, 이러한 핵심역량을 학교 교육을 통해 배양하게 하는 것이 교육 정책의 한 축을 이루고 있다. 이는 교과 중심의 전통적인 학교 교육으로는 급격하게 변화하고 있는 21세기 사회에서 성공적인 삶을 살아가는데 필요한 것들을 교육시키는 데 한계가 있다는 반성에서 기인한다. 이러한 노력에도 최근의 연구와 설문조사에 따르면 가장 부족한 핵심역량이 의사소통 및 협업 능력이라고 나타났다. 이에 본 연구에서는 의사소통 및 협업 능력 신장을 위해 최근 정보 교육이 이러한 핵심역량을 키우기 위해 초점을 맞추고 있는 컴퓨팅 사고력 교육 수업에 어떻게 적용할 수 있을지 사례를 제시하고자 한다.
