Background (Cont.) Constant changes in technology Learners have no enough time staying at classroom Technology of Computer & Communication Distance education system When separated with instructor by space and/or time, learners staying far away can participate in a course on-line or off-line.

Constant changes in technology

Learners have no enough time staying at classroom

Technology of Computer & Communication

Distance education system

When separated with instructor by space and/or time, learners staying far away can participate in a course on-line or off-line.
