However, Internet service is not readily available in underdevelop areas of the world. The new electronic distance education technologies make it possible to implement delivering instruction on a large, world-wide scale. Multimedia EDE is becoming a practical reality. Traditional EDE efforts often put the emphasis on electronic delivery systems for slickly packaged instructional material.

What happens at the other end of the instructional delivery pipeline, i.e., the learning, is greatly influenced by how much interactions students have with the instructor and with each other. One dominant distance education model involves lesson delivery as one-way video broadcasts, with a return telephone path for questions and feedback. There is often no convenient way for students to send questions to the instructor, to share ideas among themselves after the scheduled broadcast time or to access other relevant information. Any follow-on learning activities encouraging students to work collaboratively are difficult to manage. Televideo lectures, we believe, can now be supplemented by follow-on learning activities.
