1. Introduction
According to Keegan (2002), definition of distance education can be summarized as “teaching and learning in
which learning normally occurs in a different place from teaching”. He further states that in distance education,
materials and support structures are planned and prepared by an educational organization which uses technical
media to unite teacher, learner, and content. Keegan’s description of the distance education environment highlights
various interacting components of distance education such as instructor, students, and content. Information and
communication technology (ICT) makes interaction in this environment possible where every component plays a
significant role in producing the desired outcome.
