Alternatively, a pair of headphones can be plugged into the audio socket on the CD-ROM drive. The Tutorials will operate under any resolution, but from a convenience perspective, a resolution higher than 640 X 480 is preferable. A higher resolution means the instruction window takes up less screen space, making it less likely to obscure your view of the rest of the screen. How long the course takes depends very much on the individual and their circumstances. Another very important variable concerns the level of understanding you are aiming at.
All computer programmers presume some level of competency in the intended users of their programs.
We have endeavoured to minimise that presumed level. Once you start the tutorial it is important to read the instructions, even if they are very brief and in the main obvious. Nevertheless, you need to take a few minutes finding out how to run the tutorials. There are several reasons why CBTs are being recognised as being more cost effective. Retention has been demonstrated many times in the last decade to be better with computer based training, presumably because it is learning that is more active.
