대학교육에서 이상적인 '집단지성기반의 협력학습' 모델은 아직 합의되지도 않았고 여전히 이론적인 수준에 머물러 있다. 집단지성기반의 협력 학습이 되기 위해선 다양한 구성원들이 자신이 가진 최대한의 역량을 동원하여 공동의 목표 달성을 위한 기여에 능동적으로 참여할 수 있도록 촉진하고 배려해야 한다. 아직 교육현장에서 실제 모형이 개발되지 않고 있는 집단지성기반의 협력학습모델은 창의적 융합인재 양성에 핵심적 프로그램이라 판단된다. 그러하기에 현대 강연의 주요 특징인 집단지성형 콘텐츠로의 진화는 수시로 확인하고 눈여겨 볼 필요가 있다. 그와 연관된 시도의 일환으로 본 연구는 tvN이 기획하고 시도한 커넥티브 강연쇼 '창조클럽 199' 콘텐츠에 주목하였다. 지향하는 기획 의도도 시대의 요구를 잘 수렴하고 있지만 더욱 돋보이는 것은 참여자들과 함께하는 집단지성 기반의 '방법' 들을 현실에 구현해내었다는 점이다.

비대면 수업을 통한 블렌디드 러닝과 인공지능 융합 교육으로의 변화가 가속화되고 있는 교육환경은 디지털 리터러시 함양을 기초소양으로 하고 있다. 이 연구에서는 비대면 수업의 문제점을 보완하며 등장한 메타버스 플랫폼에서 디지털 문해력을 기르기 위한 협동 SW 교육 프로그램을 만들어 미래 역량에 대한 효과성을 검증하고자 하였다. 의사소통 및 협업의 기회가 적은 소인수 학습 간 클러스터를 구축하여 메타버스 안에서 협력적 의사소통을 기반으로 한 SW 교육을 진행하는 방법으로 총 20차시 프로그램을 구성하였다. 연구의 효과성을 검증하기 위해 미래 교육 역량으로 제시되는 4C 역량을 효과성 도구로 선정하여 집단 동질성 검사와 대응표본 t검정을 실시하였다. 연구 결과 메타버스 기반 협동 SW 교육 프로그램은 협력적 의사소통 능력 향상에 효과적으로 나타나서 블렌디드 러닝을 통한 SW교육의 가능성을 확인하였다.

This study aimed to develop a new convergence course applying project-based learning (PBL) and collaborative teaching methods and identify its educational effects. The course development proceeded as follows: First, three instructors collaborated to define course goals, plan objectives, content, and methods, and create a syllabus for a PBL-based fashion studio course. Roles were divided to maximize expertise: one instructor focused on fashion design, another on three-dimensional cutting, and the third on flat cutting, and digital techniques. Second, the classes were conducted and feedback on student progress was shared, enhancing class quality and engagement. Third, teaching effectiveness was assessed through learner evaluation questionnaires, reflection journals, and performance assessments. Lastly, based on the results from these evaluations, positive aspects of the course were reviewed, and ways to modify it and enhance course quality for continuous improvement were explored. The results showed high satisfaction with the learning effects on major competencies, indicating that students not only effectively learned major skills but also improved their communication and teamwork. The students perceived the teaching methods positively allowing them to be more active in class. Instructors noted that the course produced higher-quality design and production outcomes compared to previous courses. Overall, the course applying PBL and collaborative teaching methods was found to improve educational quality and effectiveness, making it a valuable approach for learner-centered education.

Children exhibit different behaviors, skills, and motivations. The main aim of this research was to investigate children's sensibility factors for icons, and to look for the best typeface for application to Web-Based Instruction (WBI) for e-Learning. Three types of icons were used to assess children's sensibilities toward metaphors: text-image, representational, and spatial mapping. Through the factor analysis, we found that children exhibited more diverse reactions to the text-image and representational types of icons than to the spatial mapping type of icons. Children commonly showedn higher sensibilities to the aesthetic-factor than to the familiarity-factor or the brevity-factor. In addition, we propose a collaborative-typeface system, which recommends the best typeface for children regarding the readability and aesthetic factor in WBI. Based on these results, we venture some suggestions on icon design and typeface selection for e-Learning.

The market basket data in the form of a binary user-item matrix or a binary item-user matrix can be modelled as a binary classification problem. The binary logistic regression approach tackles the binary classification problem, where principal components are predictor variables. If users or items are sparse in the training data, the binary classification problem can be considered as a cold-start problem. The binary logistic regression approach may not function appropriately if the principal components are inefficient for the cold-start problem. Assuming that the market basket data can also be considered as a special regression problem whose response is either 0 or 1, we propose three supervised learning approaches: random forest regression, random forest classification, and elastic net to tackle the cold-start problem, comparing the performance in a variety of experimental settings. The experimental results show that the proposed supervised learning approaches outperform the conventional approaches.

Recently, federated learning (FL) has increased prominence as a viable approach for enhancing user privacy and data security by allowing collaborative multi-party model learning without exchanging sensitive data. Despite this, most present FL systems still depend on a centralized aggregator to generate a global model by gathering all submitted models from users, which could expose user privacy and the risk of various threats from malicious users. To solve these issues, we suggested a safe FL framework that employs differential privacy to counter membership inference attacks during the collaborative FL model training process and empowers blockchain to replace the centralized aggregator server.

Supporting individual or group learners through designing effective learning environment has been major concern for instructional technologists. In CSCL environment, the effectiveness of learning depends not only on the design of the learning incidences but also on that of psychological environment because in CSCL the learners encounter virtually a new environment deviate from the ordinary physical world. CSCL is one of the most demanding environment for learners and thus it requires a highly refined learner support mechanisms. The purpose of the research was to devise conceptual tools for supporting learners in CSCL environment. Especially, the researchers tried to develop special kinds of scaffolding that directly support the collaborative practice in the social and psychological dimension of the learner. Body of literature on scaffolding has been reviewed and effective CSCL environments were observed and analyzed. As a result of the study, the research proposes a new type of scaffolding, named as "collaboration scaffolding" as a conceptual tool for supporting learners in CSCL environment. Also the research suggests three subtypes of scaffolds as the most typical collaboration scaffolding; emotional scaffolds, facilitative scaffolds, and exploratory scaffolds.

This study is a report of the collaborative action research which has been conducted between a Korean earth science teacher and science education researcher. A two-year long action research effort was made in order to improve the teacher’s earth science classrooms in pursuit of constructivist principles of learning. The process of the action research was described with the aim of increasing the awareness of science teachers and science education researchers regarding action research. Quantitative evidence was presented to indicate the effectiveness of the collaborative action research in creating constructivist learning environments in the classrooms. The process and quantitative evidence from the action research permitted a consideration of implications for future efforts to improve science classrooms.
