Tele Education 1. ... 1 Background of Tele-educat. ... Tele Education 1. ... 1 Background of Tele-education Tele-education has a long history beginning with systems like that for teaching children in Australian Outback, the British Open University and other such organizations. ... At the end of 1980s, the vest majority of distance education throughout the worlds was still primarily print-based. Technologies used for distance education are evolving from primarily ¡¥one-way¡¦ technologies and applications such as computer aided learning, computer based training and computer aided instruction, to more ¡¥two-way¡¦ technologies and applications such as computer mediated communications and computer conferencing systems for education. ... The reasons for this are as follows: „h a much wider range of technologies are becoming more accessible to potential distance education participants „h the costs of technological delivery are dropping dramatically „h the technology is becoming easier to use for both tutors and learners „h the technology is becoming more powerful pedagogically „h education centers will find it increasingly difficult to resist the political and social pressures of the technological imperatives. ... 2 The Emergence of Tele-education Radical changes in the computing infrastructure, spurred by multimedia computing and communication, will do more than extend the educational system, that is revolutionize it. ... Today, classroom education dominates instruction from elementary school to graduate school. This method has remained popular for a very long time and will probably persist as the most common mode of education. However, classroom education has its problems, that is the effectiveness decline with increase in the number of students per class. ... 3 Reasons for studying Tele-education The current Tele-education systems that have been applied in some countries are generally of multipoint transmission technique. ... For this case, the signals or information transmitted do not arrive at all the receiver at the same time, for example, the question raised by the lecturer might not received by the students at the same time and this is not a good environment for Tele-education system. ... Therefore, it is important to study the Tele-education technology from time to time to overcome these problems so that the Tele-education system could provide a more effective way of learning environment. ... However, this problem can be solved with Tele-education system in which the professor does not need to go anywhere else to give his lecture. ... With Tele-education system, one lecturer could deliver his lecture to as many students as possible effectively in a way that a large number of students from different sites having the same lecture at once. ... 4 Purpose of Research The purpose of this research is to study the current Tele-education system that has been applied in some countries. This study covers the background of Tele-education; that is its definition, the publications of Tele-education; that is any papers that discuss about Tele-education as a whole, the performance of applied Tele-education, and also the technology of Tele-education; that is its network architecture. But the main purpose of this study is to understand the Tele-education system that have been applied in another country and try to implement it in our country. ... 5 Acronyms ATM Asynchronous Transfer Mode CCITT Committee Consultatif International Telegraphique et Telephonique CPE Customer Premises Equipment IP Internet Protocol ISDN Integrated Services Digital Network ISO International Standard Organization JAMES Joint ATM Experiment on European Services LAN Local Area Network MAC Medium Access Control Mbone Multicast Backbone PC Personal Computer POP Point-of-Presence PVC Permanent Virtual Channel QoS Quality of Service RAT Robust Audio Tool SLIP Serial Line Internet Protocol TCP-IP Transmission Control Protocol - Internet Protocol TES Tele-Educational Service UI User Interface VIC Video Conferencing Tool VP Virtual Path VPN Virtual Private Network VSD Virtual Student Desktop WAN Wide Area Network WWW World Wide Web XC Cross Connect 2.0 METHOD OF INVESTIGATION Since Tele-education is a very new technology that is popularly discussed today, it is quite difficult for me to find any books that discuss about Tele-education from the library. ... I have surfed and found many interesting sites that discuss about Tele-education. Besides surfing, I also have contacted several people who are involved in this area, Tele-education, by e-mail . ... 1 Definition of Tele-education What is Tele-education? Before discussing about what Tele-education means, lets look at what distance learning is. This is because Tele-education and distance learning are very related to each other. ... But Tele-education is more than that of distance learning. In Tele-education, not only asynchronous but synchronous learning is also made possible. In other words, Tele-education is the evolution of distance learning. ... The combination of the lecture-part, group-work-part, and self-study-part is another type of Tele-education learning environment, which is synchronous learning. ... Tele-education use the technology of video teleconferencing that allows two or more parties at different geographical area to interact with each other or to have learning process together. But people usually get confused whether video teleconferencing can be considered as Tele-education as well. Tele-education is actually different with video teleconferencing in a way that Tele-education usually involve a large number of people as compared to video teleconferencing, that is, it is in video teleconferencing many people use a single monitor to see other people at other area but in Tele-education, students have their own monitor that can be used not only to see their lecturer and colleagues but also to send and receive educational materials. ... 2 Publications of Tele-education There are many papers discussing about Tele-education. Most of these papers cover only the general or overall scope of Tele-education. The area of discussion on Tele-education can be summarized as the following: „h Tele-education service „h Content of Tele-education „h Network architecture „h performance of Tele-education „h operation and management of Tele-education For Tele-education service, it describes about what multimedia tele-service and hyper media service is, and how it can be integrated into Tele-education service. It also describes about what Tele-education service facilitate. Content of Tele-education describes about the style or mode of Tele-education system, that is, what kind of education style used, and how the lecture notes or any materials delivered to all the students. For network architecture, it describes about the protocol used for the Tele-education system and its network infrastructure. Performance of Tele-education covers the performance of service of Tele-education and also the network performance. ... For the operation and management of Tele-education, it describes about what should be taken into consideration in order to provide a well managed Tele-education service. ... 3 Examples of Systems From the study of materials gathered, there are generally three examples of Tele-education system that have been applied in the Europe and Canada. Those examples are: „h Tele-education NB „h Delta s Virtual College „h ACTS Project AC052 (RACE Project Report) The purpose of looking into these examples is to try to understand what kind of Tele-education system is implemented, how Tele-education can be implemented, to know what are the requirements to implement it, and what considerations should be taken into consideration for implementing it. ... 1 Tele-education NB Tele-education NB is implemented at the University of New Brunswick, Canada. The present physical network consists of three independent networks that operate on telephone lines; „h Voice „h SMART 2000 computer teleconferencing „h Computer Mediated Communications using NBNet The SMART 2000 bridge for computer software sharing and audiographic teleconferencing is owned and operated by the Tele-education NB. ... Data communications are transmitted over NBNet using a SLIP server which resides in a user friendly simple menu front-end created by Tel-education NB to permit easy access to NBNet and to facilities available. ... Tele-education NB also supports an on-line learning center with a file server located at Mount Allison University. Information of relevance distance education and the network in particular can be accessed there. In Tele-education NB, a special listserv is created for internal communications among different sites. As an integral part of the provinces electronic information highway, Tele-education NB is supporting the development of an open, distributed network, taking advantage of media available. ... Tele-education NB placed routers in the Community College Campus in each region, and other sites in regions that do not have a college. ... Tele-education NB are now experimenting with synchronous transmissions using the TCP-IP protocol on NBNet. ... Tele-education NB has provided the guidelines for selecting appropriate technology for its network as follows: „h The network shall experiment with different technologies and endeavor not to rely on any one technology or any supplier. „h Existing equipment and distance education sites in the province shall be integrated into the network wherever possible. ... It offers the opportunity for students to participate in desktop Tele-education from their homes or offices. This concept means that individual students participate in Tele-educational courses using a desktop computer online connected to a course provider. ... 3 ACTS Project AC052 (RACE Project Report) This is a big project on Tele-education. It covers the whole aspects that should be taken into consideration for implementing Tele-education in Europe such as service aspects, management aspects, network architecture, etc. In this project, there are several trials have been done in order to obtain an effective Tele-education system. ... 0 CONSIDERATIONS It is not easy to find materials or any papers reporting the architecture of Tele-education.
