How extraordinary that this wonderful tool - probably the best ever invented for presenters - has caused a decline in the quality of presentations. When PowerPoint first arrived, there were two reactions. Many presenters thought, excellent, now I don't have to be the centre of attention, and moved to the side of the room to provide commentary. Others thought, excellent, now I can impress everyone with whizz-bang electronic effects, and set about annoying their audiences. Many believe that using PowerPoint automatically makes them effective, when the reverse is usually true.
PowerPoint is a brilliant visual aid, but only when it is used correctly.
Traditional use of PowerPoint stifles discussion and critical thinking, and dulls focus. It's boring. Slide after slide switches audiences off, steadily reducing their ability to take in information. You are wasting your time - and theirs.
