ABSTRACT

All there is to thinking . . . is seeing something noticeable which makes you see something you weren't noticing which makes you see something that isn 't even visible (Norman Maclean-A River Runs Through It)

Introduction

In recent years extensive investments in information technology have taken place in organisations involved in education and training. For example, more than a quarter of U.S. college courses now involve use of email or internet resources, and more than 10% use some form of multimedia resources. The size of this investment is estimated at over US$70 billion in the past decade and a half (Geoghegan, 1994). Detractors of this headlong rush down the superhighways of information technology have criticised the tendency to use technology as a cheap substitute for human instruction without first determining that the use of IT will increase the quality of the training provided.
