Tele education
Tele-education1.0 INTRODUCTION
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. These built on the idea of correspondence courses where course materials are sent periodically by post and augmented the experience with broadcasts either on radio or on TV. The problem of student isolation was addressed partially through techniques such as telephone access or two-way radio links with teachers. 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 significance of ‘two-way’ technologies is that they allow foe interaction between participant and tutors, and perhaps even more significantly amongst participant themselves. This development has allowed and in some senses force researches to look more closely at the impact of educational environment, on the students learning experience.
In the future, it is expected that the telecommunications-based technologies to become the primary means of delivery of distance teaching. The reasons for this are as follows:
a much wider range of technologies are becoming more accessible to potential distance education participants
the costs of technological delivery are dropping dramatically
the technology is becoming easier to use for both tutors and learners
the technology is becoming more powerful pedagogically
education centers will find it increasingly difficult to resist the political and social pressures of the technological imperatives.
1.2 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. Technological advances will make classrooms mush more accessible and effective. 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. Other pressures affect the instructors, many of whom are not experts in the material they must teach, are not good ‘performers’ in class, or simply are not interested in teaching. The biggest limitation of the classroom instruction is that a class meets at a particular time in a particular place. This essentially requires all students and the instructors to collect in one spot for their specified period. But with the emerging technology, these problems can be overcome.
1.3 Reasons for studying Tele-education
The current Tele-education systems that have been applied in some countries are generally of multipoint transmission technique. It is found that, this kind of transmission...
