Computers have had a huge impact on education and, especially, on training.    From simple early packages to CD ROMS, simulations and the internet, using computers has empowered educators.

Various terms have been used to describe such learning.    But, as ever, the array of such terms is bewildering, and there is little consistency in their use.

At its simplest, learning is said to be "based" on the delivery mechanism concerned:   computer-based, web-based, internet-based, or technology-based.    Yet, even here, there is no consensus; instead each term has its own adherents.

More often, learning uses the technology without being wholly based upon it.    So other, broader, terms are used - e-learning, online learning, and blended learning - all of which stress that technology is a part, if not the whole.

Even the older terms have been hijacked.    Distance learning is often defined nowadays as if it depends on technological delivery.

For example, the online "whatis" encyclopedia says that "distance learning, sometimes known as e-learning, is a formalised teaching and learning system specifically designed to be carried out remotely by using electronic communication" [1].

Superimposed on all this linguistic confusion is fashion.    Before the internet we talked about computer-based learning.    Then it became online learning.    Five years ago, e-Learning was the all-embracing term.    Then blended learning took its place.    Pundits predict that, in five years time, yet another term will have displaced them all, though there is, as yet, no consensus as to what this new term might be (see, for example, [2])
