가상학습은 지식 정보화시대를 맞이하여 국내외으로 새로운 교육훈련 패러다임으로서 시간과 공간을 초월한 얼린 학습공간으로 부각되고 있다. 특히 정보처리 기술의 급속한 발전으로 국내외 각종 정규·사회 교육기관에서는 인터넷을 이용한 가상학습 교육훈련을 전극 도입하고 있는 추세이다. 가상학습을 기반으로 하는 코스웨어 개발이냐 학습평가에 관한 연구는 많으나 품질평가에 관한 연구는 아직까지 미비하여 본 논문에서는 가상학습 지원시스템의 품질평가 모델을 제시하여 교육 현장에서 가상학습 지원시스템 구축 시 품질평가 기준으로 활용하고자 한다.

가상현실(VR； Virtual Reality)시스템은 매우 다양한 분야에 응용되고 있다. 이미 건축, 오락, 교육훈련 등의 분야에 많은 응용사례를 가지고 있다. 산업안전 분야에서도 가상현실을 이용한 안전교육에 대한 가능성이 제기된 바 있다(박재희와 양동주, 2000) 이러한 가상현실 시스템은 기존의 교육 매체인 도해, 모형, 비디오 등에 비해 현실감(presence)이 높고 상호작용성(interactivity)으로 인해 교육효과를 높을 수 있다.(중략)

In this thesis. we present the cyber lecture system based on XML 3-tier that uses the communication network as the internet. The system was designed to analysis the existing cyber lecture system and its details and to examine web system architecture and XML 3-tier model. With the designed system, we developed the cyber lecture system. We tested the existing system for performance and problem, then we improved the method of the cyber lecture system used by XML 3-tier Model. The cyber lecture system is offered the handiness of the cyber lecture system using web interface.

This study aims to suggest a evaluation methodology of cyber-education. In spite of rapid development of information technology for cyber-education, there are few research of evaluation methodology in cyber-education environment, we suggest a definition of criteria and a methodology of system solution selection for cyber-education system. Considering an interdependent relationship among criteria, we shows a process of an evaluation method or a selection method for evaluation of cyber-education system solution through an example.

With the growth of the Internet, web-based cyber education is progressing from the text-based to the hyper-based including multimedia, and from one way of simply giving the contents to the learner to another way of providing mutual interaction between the instructor and the learner. For this, there uses the RIA-based dynamic application and multimedia. RIA, which is the new paradigm on the web, provides the learners with more effective and rich contents. For developing a cyber education system, if we use the existing web languages, a large amount of effort is needed. But if we use the RIA-based paradigm, we can remarkably reduce the effort. Also, in developing a new web-based cyber education system the RIA paradigm makes the learners to satisfy their demands, and in developing the system providing the interaction the paradigm gives us the way minimizing the time and effort. In this paper, we compare and evaluate the efforts in developing the RIA based education system with the Non-RIA based education system.

In this paper, we propose a system to a criminal profiling simulation training and assessment with virtual reality technology. Profiling has emerged as the incidence of violent crime has increased by 45.2 % in the country over the past decade. However, the number of profilers in Korea is 36, due to the problem of existing courses. "Criminal Reproduction Learning" is the common way to profiling training, but there are numerous constraints that prevent practical training. Thus, the system used virtual reality technology to overcome existing constraints. Users can receive simulation training and assessment of profiling at crime scene that have been implemented as virtual reality, with an immersive experience through interaction. We expect this system to contribute to the activation of profiling education in many institutions and to the development of good profilers with diverse training.

본 시스템은 4 차 산업 혁명이 발발한 이점을 살려 가상현실(Augmented Reality)을 활용, 극대화된 시각적인 요소들을 추가하여 사용자들의 흥미를 유발한다. 또한 더욱 정확한 평가 기준을 세우기 위해 사용자의 흉부 압박 빠르기와 깊이를 측정할 수 있는 각종 센서를 활용하였다. 관리자는 신뢰성 있는 데이터를 바탕으로 사용자들을 평가한다. 기존의 평가는 평가자의 눈대중, 직감으로만 평가가 이루어지기에 신빙성 및 신뢰를 하기 어렵다. 따라서 사용자들은 현실감 있고 정량화된 데이터를 바탕으로 정확한 평가 및 피드백을 받을 수 있는 교육, 평가가 절실히 필요하다. 따라서 본 논문에서는 가상현실을 활용한 심폐소생술(CPR) 및 자동 제세동기(AED) 교육 평가 시스템을 제안한다.

정보통신 분야의 혁신적인 기술개발로 최근 인터넷 기술을 이용한 다양한 분야에서 응용이 활발해지고 있다. 이러한 환경의 변화는 인터넷 서비스의 하나인 웹의 사용과 함께 교육분야에도 원격, 가상교육이라는 대안적 교육 체제를 탄생하게 하였다. 웹 이전의 교육용 시스템들은 텍스트나 간단한 그래픽 기반의 단방향의 학습과 평가가 가능했었다면, 웹의 분산 환경 제공으로 양방향의 상호 작용적 학습이 가능해졌을 뿐만 아니라 실시간 학습과 평가를 가능하게 해 주었다. 본 논문에서는 웹 기반 문제은행 시스템의 장점을 이용하여 학습자의 평가 정보를 시스템이 분석하고 학습자의 수준에 맞는 문제를 제공함으로써 수준별 학습이 가능하도록 하였을 뿐만 아니라 학습자에게 가장 많이 틀린 단원의 문제에 대해서 보충학습의 기회를 제공함으로써 학습효과를 극대화할 수 있는 시스템을 설계하였다.

Recently, web-based E-learning systems have entered the spotlight by providing new learning environments that break down spatial and temporal limitations. The key to building the web-based E-learning system is in determining how to effectively use the system and to evaluate the degree of learning achieved by the students that use it. In traditional off-line learning systems, we can evaluate students by counting how many questions, designed to evaluate their learning achievement, he or she answers correctly within a predetermined time limit. But this method would make individualized learning, a strong point of E-learning systems, impossible because these systems provide same learning strategy to all students even though they achieve a different level of learning. Therefore, in this paper, I will find any relationships between given test answers using fuzzy implication theory, I call these fuzzy correlations, and then generate evaluation results that are reflected in those relationships. I will compare the differences between this evaluation method and a traditional evaluation method where a student takes a test to evaluate his or her learning achievement after some learning period. Finally, I will discuss how we can use these results in individualized learning.
