As a result of the increasing application of ICTs in education, a number of new learning approaches have emerged. E-learning encompasses learning at all levels, formal as well as non-formal, using information networks such as the Internet, an intranet (LAN) or extranet (WAN) for course delivery, interaction and facilitation. Blended learning refers to learning models that combine traditional classroom practice with e-leaning solutions. The blending of different methods was developed after educators recognized that not all learning is best achieved in an electronically-mediated environment, in particular one that dispenses with a live instructor altogether.
Open and distance learning is a learning approach in which teacher and learner are separated in time or place and uses a variety of media, including print and electronic, to ensure a two-way communication that allows tutors and learners to interact.
