Technologies For Distance Education.




Changes in the types of technologies available for delivering distance education, including changes in the capabilities of networking technology and the rise of the Internet, have played a role in the adoption of distance education by post secondary institutions.

The following are the common technologies available for the instructional delivery of distance education courses.

  1. Video technologies: Two-way video with two-way audio (also referred to as two-way interactive video).

  2. Audio technologies: Two-way audio transmission

  3. Internet-based technologies: Internet courses using synchronous (i.e. simultaneous or `real time') computer-based instruction (e.g. interactive computer conferencing or Interactive Relay Chat), and Internet course using asynchronous (i.e. not simultaneous) computer-based instruction (e.g. email, list-serves, and most World Wide Web-based courses).

  4. Other technologies: CD-ROM, mixed mode packages (i.e. a mix of technologies that cannot be assigned to a primary mode) and an open-ended `other, specify' category.

Resource persons pointed out that more powerful satellite, improved designs, innovations and advancements in ground reception technology are likely to lead to a considerable reduction in the overall cost of satellite technology; it is simple to install direct reception community sets for the benefit of schools and colleges.

Technology has come to stay as the backbone of communication in distance teaching methodology. Communication technology has found a client in the distance education system. That is, distance education represents the transformations of education from stage of craft to the stage of technology, thereby making room for increased productivity
