Distance learning is a mode of providing education and training, often on an individual basis, to students who are not physically present in a conventional setting such as a class room. Distance learning systems provide “access to education when the source of information and the students are separated by time or distance, or both.” Nowadays, online learning, usually in college-level, where students work on their own at home or at the office and interaction with faculty and other students via e-, digital forums, video chat, message boards, instant messaging and other forms of computer-based communication. Most distance learning systems include a computer-based training (CBT) program and communication tools to produce a virtual class room. Because the World Wide Web is accessible from virtually all pc systems, they serve as the foundation for distance learning methods.
The first online learning course in the modern era was provided and developed by Sir Isaac Pitman in the 1840s, who taught a system of shorthand by mailing texts transcribed into shorthand on post cards and receiving transcriptions from his students in return for correction, the element of student feedback was crucial advancement of Pitman’s program.
Audio Based – It is distance learning method utilizing one-way or two-way interaction. This includes everything from radio broadcasting and phone conferences to pre-recorded audio CDs.
Video Based – There are two basic types of video distance learning courses:
- Prerecorded Video – videotaped courses are sent to students who can view them at an off-site location.
- Two-Way Interactive Video – Satellites, cameras, and computer monitors allow teachers and/or students at another website.
Internet Based – Web centered applications require a web based accessibility and little else. Students of online distance learning applications often receive training through websites, email, digital forums, and messaging systems. These applications generally offer the same program as on-site applications and usually come with an adjusted price tag. Perhaps this is why internet distance learning is becoming so popular. Distance education and learning technologies are separated into two ways of delivery: synchronous learning and asynchronous learning. In synchronous learning, all members are ”present” simultaneously. In this regard, it appears like conventional class room teaching methods despite the members being located remotely. It requires a schedule to be organized. In asynchronous learning, members access course materials flexibly on their own schedules.
