본 연구에서는 초속망의 원격교육을 지원하는 그룹 관리 시스템을 연구하였다. 효율적인 원격교육을 위해서는 가상클래스 상의 피관리 객체와 그 동작들을 관리, 제어하는 메카니즘이 필요하며, 교수자는 학습그룹 및 하나의 학습그룹을 형성하는 학습자의 다양한 상태변화를 직시할 수 있어야 한다. 그리고, 가상클래스 상에서 교수자와 학습자는 학습그룹에 따라 토론하고 상호 메시지 송수신이 가능해야 한다. 본 논문에서는 이러한 가상클래스 운용을 위한 그룹 관리 및 관리정보베이스 모델을 제안하고 거기에 요구되는 그룹관리 알고리즘을 연구하였다.

In this study, 27 pre-service teachers presented virtual mathematics instruction to develop his/her own teaching practice ability. I found several attributes in their virtual mathematics instruction such as connecting contents, asking justification, encouraging students' communication, representing variously, and using ICT etc. These will be the characteristics of the future mathematics class. When peer pre-service teachers assess presenter's instruction quantitatively, there are differences in the results between expert and pre-service teachers. Pre-service teachers didn't find the elements of student self assessment or group assessment and communication activities at the virtual instruction. When they assess peers' virtual instruction qualitatively, the results are specific or new ones compared with the quantitative assessment elements. Thus I suggested some implications for the mathematics pre-service teachers' virtual instruction in the view of teacher education.

가상 환경에서의 학습 시스템은 기존 E-Learning 시스템에서 부족했던 몰입감을 주고 사용자의 흥미 유발을 촉진할 수 있고 위험하거나 비용이 많이 드는 교육 컨텐츠를 제공할 수 있다. 본 논문에서 학습 유형을 실시간 강의, 상시 학습, 실습 교육, 그리고 스터디 그룹 활동으로 구분하였다. 혼합 현실을 제공하는 가상 세계인 Second Life를 이용하여 이들 학습 유형을 지원하는 온라인 강의 시스템을 구축하였다. 구축된 온라인 강의 시스템을 운영함으로써 가상 학습 환경을 제공하였다.

이 연구의 목적은 영어교육에서 가상현실 활용 교육이 효과적으로 이루어지기 위한 방안을 도출하기 위한 것이다. 이를 위하여 영어교육 현장 교사를 대상으로 가상현실을 활용한 영어교육에 대한 인식을 종합적으로 조사·분석하였다. 연구결과, 첫째, 현직교사들은 가상현실 활용 영어교육의 필요성에 대해 긍정적으로 인식하고 있으나, 대부분의 교사가 가상현실 활용 교육에 대해 심리적 부담감을 호소하는 것으로 나타났다. 둘째, 가상현실 기반 영어콘텐츠가 교육현장에 실용적일 것이라는 기대에 대해서는 긍정적인 반응보다 부정적인 반응이 다소 높은 것으로 나타났다. 셋째, 가상현실 활용한 영어교육이 효과성을 높이기 위해서는 가상현실의 교육적 활용에 대한 경험공유, 다양한 가상현실 콘텐츠 제공이 필요하다고 하였다. 넷째, 가상현실 교육적 활용을 위해서는 가상현실을 적용한 교수학습 방법교육 및 연수와 가상현실 활용 교육에 대한 가이드라인 제공에 대한 요구도가 높은 것으로 나타났다.

This research examined the difference in cognitive load and the virtual presence depending on auditory feedback and task difficulty in haptic-based dental simulation. In the field of dental education, practice-centered training using handpiece has been crucial because a practitioner's psychomotor experience has a significant impact on the mastery of treatment skills. For the novice, it is necessary to reduce errors in dental treatment to enhancing skill acquisition in the haptic practice. In the training process, the force-feedback is crucial to elaborate subtle movement to guide what to do and how it should be hard or soft. However, It is not easy to add force-feedback to generate kinetic experience training. As an alternative method, we examined that auditory feedback can help learners' skill training. In this study, we analyzed how the presence/absence of auditory feedback at the different levels of task difficulty impacts learners' psychological demand and virtual presence in the virtual reality simulation. For this study, 29 dental college students participated in a dental simulation. The participants were grouped into two conditions that are with and without auditory feedback. Additionally, two consecutive tooth preparation tasks with different levels of difficulty were used in the simulation. The auditory feedback condition gives alarms to a learner when he treats a non-targeted tooth with a virtual handpiece. The user's cognitive load and virtual presence were measured to examine the effects of auditory feedback. The results revealed that the main effect was found in cognitive loads. Also, a significant interaction effect was shown in the virtual presence. We discussed the effective design methods for the virtual reality-based dental simulation through the result of this study.

The research of combining virtual reality technology with the design elements of children's picture book education is a relatively new topic in virtual reality technology in recent years. Based on the combination of picture book design elements with virtual reality technology and the development of a children's picture book teaching game, this article analyzes the effectiveness of the application of virtual reality technology in children's teaching, and explores the usability of picture book design elements in teaching [1]. Through literature research methods, practical research methods and investigation research methods, this paper lucubrates the application of virtual reality technology in the design elements of children's picture book education so as to provide adequate theoretical and practical support for the research theme. The spatial positioning, vision, sound, and functional requirements of children's picture book games play a leading role in teaching. Practical statistics have proved that it is easier to promote children's mastery of teaching knowledge in a virtual environment. Moreover, use VR's game management function and setting function to solve the boringness of traditional education methods and the limitations of the teaching environment. The feasibility of game operation provides a virtual teaching platform system for children's education, and the teaching effect is remarkable.

Owing to the Corona virus (COVID-19) crisis, virtual education has been expanded. Accordingly, this study was conducted to determine the direction of oral health education by examining participants' satisfaction with virtual education and educational media preferences. This study collected data from a Naver Form online survey targeting 290 university students across the country, from May 10 to 31, 2021. The collected data were analyzed using IBM SPSS 20.0. According to the data, satisfaction with virtual classes was 3.36 points in 5-point Likert scale, satisfaction factors were reduced commuting time and money expenditure, and the highest dissatisfaction factor was a decrease in lecture concentration. The media platform that most interested students pursing oral health education was YouTube. The oral health education that participants wished to receive through virtual education included how to prevent tooth decay, how to prevent gum disease, and how to brush teeth. In conclusion, it is necessary to develop various media like Zoom, YouTube, and virtual reality programs so that students feel motivated to utilize oral health education and improve oral health.

Virtual Reality (VR) is one of the core components of the fourth industrial revolution as a technology that makes the virtual world feel as if it is real. VR is being used in various fields such as entertainment, advertisement, education, medical care, training, sports, and tourism, as well as providing contents for such things as games and videos. Libraries are already looking for ways to utilize VR from various angles, such as operating experiential programs. The purpose of this thesis is to develop and propose a VR-based library user education program. In order to achieve the purpose of the study, we analyzed previous studies from a theoretical perspective to find a way to construct a user education program, and also to derive possible implications based on examples of countries such as the United States and Korea that are already introducing and applying VR technology to library services. Therefore, the user education program proposed in this study can be used as a basic building block when many libraries want to develop VR-based programs in the future.
