Tele Education

1.0 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 technique
having several problems or defects. Mostly, problems raised during the
application of the system. One of the significant problems raised is that, for
the multipoint transmission, the signals or information transmitted by the
sender do not completely received by the receiver. This problem is might be due
to error that occurs during the transmission of the signals or information.

Another problem is lag of transmission. 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.

Some receiver receives the signals earlier than the others and some later or
even not receives at all. 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. In order to have a lecture from, for example, a very famous
professor from other country would require him to come at our place. But the
amount of money spent for paying him to give lecture would be very expensive and
this also would cause troublesome for him. 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. This would save a lot of expenses and time. Another
reason is that, in normal classes the learning process would not be very
effective if the number of students in a class is very big. This is because the
lecturer alone can not coordinate such a large class. With Tele-education
system, one lecturer could deliver his lecture to as many students as
