The most notable advantages of e-learning are flexibility, convenience and the ability to work at your own pace. E-classes are asynchronous which allows learners to participate and complete coursework in accordance with their daily commitments. This makes an e-learning education a viable option for those that have other commitments such as family or work.
Other advantages of e-learning include the ability to communicate with fellow classmates from around the country, a greater adaptability to learner's needs, more variety in learning experience with the use of multimedia and the non-verbal presentation of teaching material. Video instruction provides visual and audio learning that can be reviewed as often as needed. For organizations with distributed and constantly changing learners (e.g. restaurant staff), e-learning has huge benefits when compared with organizing classroom training.
Disadvantages of e-learning include the lack of face-to-face interaction with a teacher. Critics of e-learning argue that the process is no longer "educational" in the highest philosophical sense (for example, as defined by RS Peters, a philosopher of education). Supporters of E-learning claim that this criticism is largely unfounded, as human interactions can readily be encouraged through audio or video-based web-conferencing programs, threaded discussion boards,of fact, many in K12 would support e-learning if it was not associated with the more extreme versions that attempt to cut out the directed teacher-student relationship.
The feeling of isolation experienced by distance learning students is also often cited, although discussion forums and other computer-based communication can in fact help ameliorate this and in particular can often encourage students to meet face-to-face and form self-help groups. Discussion groups can also be formed on-line. Human interaction, faculty-to-student as well as student-to-student, should be encouraged in any form.
Web and software development in particular can be expensive as can systems specifically geared for e-learning. The development of adaptive materials is also much more time-consuming than that of non-adaptive ones. Consequently, some of the cost is often forwarded to the students as online college courses tend to cost more than traditional courses. However, there are transportation cost (and time) benefits with not having to commute to and from campus.
