Distance learning can defined as learning where the instructor and the students are in physically separate locations. The various technologies used in distance learning can be roughly divided into four categories: print, audio, computer and video. The explosion of the internet, coupled with advances in educational software, has fuelled distance learning and online education throughout the world. Not only is distance learning convenient, it is also effective. Several research studies have found that distance learning is equally or more effective than traditional instruction when the method and technologies used are appropriate to the instructional tasks, when there is student-to-student interaction, and when there is timely teacher-to-student feedback. This book is intended for educators who are interested in implementing distance learning technologies. It provides an overview of the advantages and characteristics of the various technologies now being used to teach learners.
