E-learning comprises all forms of electronically supported learning and teaching. The Information and communication systems, whether networked or not, serve as specific media to implement the learning process. E-learning is essentially the computer and network-enabled transfer of skills and knowledge. E-learning applications and processes include Web-based learning, computer-based learning, virtual classrooms and digital collaboration. Content is delivered via the Internet, Intranet/Extranet, audio or video tape, satellite TV, and CD-ROM. The courses can be Self-paced, Instructor-led, Webinars, Videos, Podcasts etc. and can include media in the form of text, image, animation, streaming video and audio. First, lets look at a classification of various forms of learning delivery.
Self Paced courses are courses that the learners complete at their own pace within an allotted time but without the assistance of a live instructor. Learners can take these courses at any convenient time and often over an extended period of time.
Instructor-led Training (ILT) refers to traditional in-person classes. There is a live instructor and all the attendees are physically present in the same classroom.
Video courses are those that are available in video form (wmv, Flash formats are most common) and this is a type of self-paced course.
Podcasts similarly are courses that involve only audio without the video. These can be considered as a form of self-paced course.
