Recently, interest in AI tutors is rising as a way to bridge the educational gap in school settings. However, research confirming the effectiveness of AI tutors is lacking. The purpose of this study is to explore how effective learner characteristics and recommended item learning activities are in predicting learner's academic performance in an adaptive online learning environment. This study proposed the hypothesis that learner characteristics (prior knowledge, midterm evaluation) and recommended item learning activities (learning time, correct answer check, incorrect answer correction, satisfaction, correct answer rate) predict academic achievement. In order to verify the hypothesis, the data of 362 learners were analyzed by collecting data from the learning management system (LMS) from the perspective of learning analytics. For data analysis, regression analysis was performed using the regsubset function provided by the leaps package of the R program. The results of analyses showed that prior knowledge, midterm evaluation, correct answer confirmation, incorrect answer correction, and satisfaction had a positive effect on academic performance, but learning time had a negative effect on academic performance. On the other hand, the percentage of correct answers did not have a significant effect on academic performance. The results of this study suggest that recommended item learning activities, which mean behavioral indicators of interaction with AI tutors, are important in the learning process stage to increase academic performance in an adaptive online learning environment.

연합학습은 학습데이터의 전송없이 모델의 학습을 수행할 수 있는 학습방법이다. IoT 혹은 헬스케어 분야는 사용자의 개인정보를 다루는 만큼 정보유출에 민감하여 시스템 디자인에 많은 주의를 기울여야 하지만 연합학습을 사용하는 경우 데이터가 수집되는 디바이스에서 데이터가 이동하지 않기 때문에 개인정보 유출에 자유로운 학습방법으로 각광받고 있다. 이에 따라 많은 연합학습 구현체가 개발되었으나 연합학습을 사용하는 시스템의 개발과 운영을 위한 시스템 설계에 관한 구체적인 연구가 부족하다. 본 연구에서는 연합학습을 실제 프로젝트에 적용하여 IoT 디바이스에 배포하고자 할 때 연합학습의 수명주기, 코드 버전 관리, model serving, 디바이스 모니터링에 대한 대책이 필요함을 보이고 이러한 점을 보완해주는 개발환경에 대한 설계를 제안하고자 한다. 본 논문에서 제안하는 시스템은 중단 없는 model-serving을 고려하였고 소스코드 및 모델 버전 관리와 디바이스 상태 모니터링, 서버-클라이언트 학습 스케쥴 관리기능을 포함한다.

국어를 공부하는 외국인 학생들이 몇 년간 급격하게 증가하면서 한국어의 국제적인 지위가 올라가고 있다. 하지만 외국인 학생들의 입장에서는 한국어를 배우는 과정에 많은 어려움을 겪는 점이 드러나고 있다. 또한 이에 더해 한국 학생들과 외국인 학생들간의 이해관계가 어려워지는 점을 지적하는 연구가 나오고 있다. 에린 샌더의 디자인 연구 스파이럴을 통해서 이 논문은 한국에 있는 외국인 학생들의 한국어 교육경험을 조사했다. 또한 이 학생들의 한국어 학습에 대한 인식과 효과적인 요인들을 분석하였다. 결론적으로 본 연구는 디자인 연구를 통해 한국어 학습에 중요한 통찰을 결과로 도출했으며, 외국인 학생들이 한국어를 효과적으로 공부하는데 기여할 디자인 기회를 도출한 의의가 있다.

This is an extended paper explaining the role of E-learning and quality development in the current situation. Amid Covid:19, E-Learning has achieved a new miles stone in imparting education and all levels of institutions have transformed their learning platform from face to face to virtual learning. In this scenario E-Learning is facing two major challenges, first to ensure the ability of computer systems or software to exchange and make use of information on virtual platform (interoperability) and secondly, developing quality learning through e-Learning. To impart learning and teaching (L&T) through E-learning, Middle East University (MEU) has adopted Learning Management Services (LMS) through Blackboard. The university has three types of L&T methods; full online, Blended and Supportive. This research studies the concept, scope and dimensions of interoperability (InT) of E-Learning in MEU then the connection and interdependence between with quality development. In this paper we have described the support and the importance of finest standards and specifications for the objectives of InT of E-Learning and quality development in MEU. The research is based principally on secondary data observed from MEU E-Learning deanship. Also sample of 20 E-Learning experts at MEU were given closed ended as well as semi closed questionnaires for evaluating the assurance of InT of E-Learning and quality development. These experts are mainly certified online facilitators and admin staff. Results provide the verification of application and presence of InT of E-Learning and assured the quality development process in MEU.

본 논문에서는 SOA(Service-Oriented Architecture)를 기반으로 서비스간에 상호 작용하는 데이터의 품질 관리를 위한 오류 정제 서비스를 대상으로 데이터 제약조건 설정 시 인간 개입을 최소화하기 위한 기법을 제안한다. 단, 실세계에서 통용되는 일반적인 데이터를 모두 다루는 것은 불가능하므로 비즈니스 도메인에서 자주 사용되는 CRM(Customer Relationship Management)과 ERP(Enterprise Resource Planning) 서비스와 같이 고객 주문 정보 및 처리에 관련된 데이터를 대상으로 한다. 이를 위해, 컴포지션 되는 서비스간의 상호 작용하는 데이터를 의미적으로 확장하여 확장-엘리먼트 벡터를 생성하고 이를 기반으로 의사결정 트리(decision tree) 학습 방법을 적용하여 제약조건 설정을 자동화하기 위한 규칙 기반 시스템을 구축한다. 이 시스템을 오류정제 서비스에 삽입한 결과, 비즈니스 분야의 공개된 서비스로부터 데이터 학습을 통해 제약조건 설정을 41% 넘게 자동화 할 수 있음을 보였다.

2010년도에 들어서면서 학령인구의 감소와 함께 고등학교 졸업생들의 대학진학률 하향추세로, 대학들은 학생 선발과 양질의 교육콘텐츠 제공이라는 2중의 어려움에 직면하고 있다. 이에 각 대학은 환경의 변화에 대한 신속한 대응과 동시에 다양하고 전문화된 대학교육서비스(팀기반 프로젝트학습, 사례연구, e-러닝, 액션러닝 등)를 도입하고 있다. 본 연구에서는 대학생을 대상으로 팀기반 프로젝트학습이 수업만족에 미치는 영향을 조사하고자 하였다. 이를 위한 측정항목으로 4개 요인(팀 응집력, 팀워크, 팀 성과 및 목표달성)을 설정하고, 설문조사(4개 과목, 34팀, 134명)를 통해서 자료를 수집하여, 구조방정식모형으로 분석했다. 연구모형검증 결과는 팀 응집력${\rightarrow}$팀워크${\rightarrow}$수업만족의 구조가 제시되었으며, 팀 성과와 목표달성은 수업만족에 미치는 영향이 유의하지 않은 것으로 나타났다. 팀기반 프로젝트학습의 경우 팀응집력이 높아야 수업만족정도가 높아지는 것으로 분석되었다.

Securing food safety, natural and social environmental protection, and activation of rural communities are some of challenging tasks for the 21st century. National consensus on agriculture as a basic and public industry would be needed to solve these challenging tasks. Agricultural policy and extension education should be focused on encouraging farmers to achieve better production and management by developing their motivation and ability. Systematic and organizational efforts to make a better environment for farming and farm management should be the major target of agricultural policy and extension services in the future. To meet changing needs of farmer, agricultural extension services should change programs, functions, information sources, and methods of delivery to adopt experiential learning for farmers. Functions for consultation, suggestion and organization should be extended and advisory services for farmers should be emphasized by providing extension education.

This study utilizes the image contents, one of the social interaction activities, in role-play. The one-semester class results were used for analysis to prepare teaching-learning plans for the department of aviation services. This study helped students in the Department of Aviation Services understand the airline cabin organization and examined whether it would help them understand the airline cabin organization and examine whether it would help them communicate with customers. In role-play classes, learners or groups of learners use role-playing dialogues to create role-plays and create communication situations similar to the real world.
