Tele Education Essays - Distance Education, Educational Technology

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

Office Art Memo - Research Paper Example From this paper it is clear that  the impressionist paintings include: A Matador, Young Woman with Ibis, and View of Vetheuil. ‘A Matador' impressionist art has color painted side by side with a little mixing, and it has a strongly colored ground. It was made by French, Edouard Manet. The ‘View of Vetheuil’ impressionist art was created in the year 1880 by Claude Monet, from France. The artwork also has a more vivid color with a light colored background. Besides, the painting is out- door with the shadowy effects detailed. On the other hand, the ‘Young Woman with Ibis’ impressionist work was an out- door painting and had no use of black color. The painting was made by a French woman, Edgar Degas, who was an impressionist. It was made in the year 1860 to 1862 and had an emphasis on natural light. The colors in the painting are placed side by side with no mixing.This discussion stresses that  there are several post-impressionist paintings and they in clude ‘Still Life with Teapot and Fruit’, ‘Tahitian Faces: Frontal Views and Profiles’, and ‘Road in Etten.’   Ã¢â‚¬ËœStill Life with Teapot and Fruit’ is non- naturalistic, even though simplified, and a trait that defies the principles of impressionist art. It has flowers hanging on their own without obeying the force of gravity. The artwork also has flat patches in bold colors, esoteric symbolism, and decorative line. Paul Gauguin, a renowned post- impressionist, made the artwork.
