Cyber lectures were expected to replace the traditional classroom lecture, yet they were criticized due to the inefficiency. With educational technology supplemented, cyber lectures have improved their efficiency through the coherence of superior planning ability and improvement in computer and network technology. This paper's purpose is to understand the factors that improve educational efficiency of cyber lectures. Cyber lecture for IT subject for software practice is created to test the educational efficiency as lecture on theories will not distinctively show the lecture efficiency. The survey was conducted to students and statistical analysis was done on collected data to analyze the factors that influence educational efficiency of created lecture.

As a promising alternative for the traditional educational system, the cyber education is in the spotlight of both educators and computer scientists. There are many advantages of online education to the students and to the institution such as easy and random accessibility, low cost, saving spaces in the institutions, and so on. or a successful online education, some important factors would be considered in constructing cyber lectures. The purposes of this paper are to investigate students'viewpoints, called factors, of the cyber class and analyze these factors to be an effective cyber class. Once factors are identified, we trace the change of the student assessments on the identified factors during the class. Using these factors, we also examine if there are any differences on the assessment of the cyber class according to student background, such as gender. major, and class.

The purpose of this study is to verify the effects of partial-cyber and full-cyber lectures and explore directions for improvement. This study compared the mean scores of course evaluation for traditional face-to-face lectures, partial-cyber lectures of blended instruction, and full-cyber lectures. Also, this study interviewed instructors of full-cyber lectures to investigate the ways to enhance the lecture quality. The findings suggest that the course evaluation scores for full-cyber university were consistently lower than those for other types of lectures for four semesters between the years of 2011 and 2012. Results also showed that mean scores of partial-cyber lectures were the same as those of face-to-face lectures. After all, class satisfaction in full-cyber courses that learning occurs in cyber space was the lowest. Instructors who taught full-cyber lectures proposed that enrollment should not be within 60 students and professional assistance should be provided for lectures exceeding 60 students. Finally, they suggested content updates through a collaborative system with professionals, instructors' efforts to enhance interaction in both online and offline contexts, and learning quantity rationalization.

The cyber-education is fully recognized and proliferated such as to Internet language centers or virtual universities, and so on. However, the acquisition of e-learning tools as well as the construction of educational contents are quite difficult tasks. Therefore, in this study, important information for the acquisition of hardwares such as multimedia editing tools, servers, educational facilities is suggested, and the critical success factors for the acquisition of cyber educational solution softwares such as authoring tools and loaming management systems are proposed.

사이버 교육 시스템 기반을 구축하기 위한 일련의 연구의 한 부분으로써, 새로이 개발된 컴퓨터 기술들이 현 가상 교육 시스템과 어떻게 융합되어 더 나은 사이버 교육 시스템을 구축할 것인가를 제시한다. 많은 IT 교육이 사이버를 통하여 이루어지고 있으나, 이는 이론 교육과는 달리 컴퓨터를 이용한 실습이 필요한 경우가 많다. 한성대학교에서 실시한 가상 강좌의 운영 경험을 제시한다. 기존 강좌와 비교하여 전산 교육을 위한 가상 강좌의 문제점과 그 개선점을 제안하고자 한다.

XML은 모든 분야의 데이터를 저장하고 다른 형태의 데이터로 변화될 수 있는 강한 힘을 지니고 있다. 웹에서의 가상 교육에 대한 데이터도 XML로 저장한다면 한번 저장된 데이터는 어떤 사이트에서든 조금의 수정없이 바로 사용할 수 있다. 물론 이 데이터 구조가 미리 정의되어 모든 사이트에서 이 구조대로 XML 데이터를 만들어야 가능하다. 현재 사이버 교육 사이트들의 강좌 데이터는 데이터베이스에, 데이터베이스에서 데이터를 가져오는 것은 ASP, 가져온 데이터를 사용자에게 서비스하는 최종 산출물은 HTML로 구성되어 있어 이 데이터는 더 이상 가공을 할 수 없게 된다. 즉 각각의 사이버 교육 사이트들의 데이터는 서로 공유될 수 없다. 본 논문은 현재 사이버스쿨의 한계를 벗어날 수 있도록 새로운 표준으로 제안되어진 XML을 이용하여 사이버 강좌 관리시스템을 위한 통일된 XML 데이터 구조를 정의하고 웹에서 어떻게 사용해야 하는지 모델을 제시하였다.

The speedy development of the world-wide web is rapidly growing the internet-based tools for the remote instruction. In interchanging and expressing the information of one another on the web, it is produced through the form of HTML(Hyoertext Text Markup Language). However, the structural disadvantage of the HTML is becoming to require a powerful XML(eXtensible Markup Language) which can store all the sphere of data, and transform them into another form. Nevertheless, because the powerful XML(eXtensible Markup Language). However necessary that XML standard should be applied appropriately. Because existing lecture data of cyber education sites cannot be shared, the users should passively use only the functions offered by cyber school. To solve the problem of this limit, in this study, the standardized data structure for XML is defined, and system model for processing between the server and the client is provided. By storing the lecture data of cyber education sites as XML on the web, stored data came to be reused without changing on any site. In the view of Users, they could used the Internet service with equipment that they want at any place and any time. To control any kinds of CK\LMS(Cyber Lecture Management System) for Administrator and Users, we offered a variety of Multimedia applications and an easy interface and built a new style of CLMS. Therefore, by strong and extracting the data related with the virtual education of the secondary school through the form of XML, for the effective interchange and sharing of the information, maximum utilization of the information can be achieved.

The purpose of this study is to develop a test and verifying the validity and reliability for measuring a effectiveness of e-earning course in cyber university. Twenty-five items were developed based on literature review and were examined by experts in the field. For item analysis, EFA(Exploratory Factor Analysis) was performed with 768 students in first study. In order to validate the test, CFA(Confirmatory Factor Analysis) was conducted with 791 students in second study. The result of the study yielded five factors with 25 items: 1) contents and design, 2) instructor, 3) system, 4) evaluation, and 5) overall course satisfaction. And this research reports the reliability and validity of new test.

This research describes the definition of the characteristics and the role of cyber education through examination of the general situations of sixteen cyber Universities which have been operated in 2003. This research argued about problems and improvements of cyber university in terms of present registration condition of each University. Through the analysis of the data of Korean Ministry of Education & Human Resources Development in 2002. This research also analyzed qualitative aspects of design education that consist in cyber university through comparative analysis of characteristics, department names, a curriculum, a taxonomy of lecture type which are related to design major in each University. As a conclusion, this research emphasized the importance and the meaning of interaction between an instructor and students for successful cyber lecture.
