Distance learning as a form of education has been developed before computer network advent, gradually increasing the range of used technologies. First they introduced a so-called case-technology: well-structured training materials were completed in a special set (“case”), which was then sent to a student for independent study. Over time, paper pamphlets and books were supplemented by records on magnetic media and CD-ROM, & teachers began using television technology conduct classes & lectures. Students still had to periodically attend full consultation of teachers (tutors) or instructors in specially created remote (regional) training centers.
The World Wide Web provided basis for network technology development to share knowledge, providing students & teachers with electronic books & libraries, convenient testing systems, as well as means of communication. Internet not only combines all previously known tools of training, but also significantly expands their list, has a significant impact on information culture in educational environment.Most of learning centers can be divided into three groups according to the degree of “immersion” into the Internet.The first group includes institutions, which work is based entirely on Internet technologies. A choice of course, its payment, training students, transfer of control tasks and their verification, as well as passing interim & final examinations are carried out via the Web. Such training centers are sometimes called “virtual universities” & not numerous because of high requirements for software program equipment & staff training, as well as the need for substantial initial investments.Article Source: http://EzineArticles.com/5826784
