Online Education

What is Online Education? • It is an extension of the traditional form of distance education.

Advantages and Disadvantages of Online Learning over Traditional Instruction

Advantages • The course become an artifact (a videotape, Web site, set of archived messages) and thus can be evaluated in detail and continually improved. • The course is available virtually any time or in any location and thus is accessible to a far broader range of students. • Students can learn at their own pace thus improving the learning process.

Disadvantages: • Success is dependent on technology. • When a course a presented to students outside the usual classroom environment, it demands a significant level of maturity and commitment from the students. • Some courses or programs demand additional support which in most cases will also have to deliver at a distance.

Student’s Perspective: • Students can learn any time. • Students can learn at any place. • Student can learn at their own pace, giving extra time to new material and speeding through material already known, with pauses for tutorial help or supplement course. • Students can learn more efficiently when concepts are presented with multiple media so students can select those which best assist their own understanding and retention.

• Students can learn only what they need to know, reinforcing both retention and motivation learning and then applying individual modules of a course. • The course content and course quality are constant; organizations can document training coverage and student learning over a wide geographical or temporal area. • The course can be examined and improved.

• The need for costly, permanent teaching facilities is reduced; learning can take place at home, in dorms and workplaces, or in temporary facilities.
