Three PowerPoint Tips, from a man who knows...

I am indebted to Tim Harford, the "Undercover Economist" , presenter of BBC Radio 4's More or Less and Financial Times columnist for these three Powerpoint presentation tips:Microsoft bought PowerPoint 25 years ago. Happy anniversary.PowerPoint has a curious status these days – it’s ubiquitous and yet widely loathed. Both the ubiquity and the loathing are overdone.Here are three tips I’ve found very useful as a speaker.1) There are three things you can do with PowerPoint (or most of its rivals). You can put visual aids on a screen; you can create bullet-point speaker’s notes; and you can produce handouts for people to take home. All of these uses are perfectly legitimate, but you can’t do them all at once. Your speaker’s notes should be on small cards in your hand; your handouts can have contact details, sources, a bibliography, or dense data; your visuals should be simple and look awesome. If you feel you need to do all three, fine: you will need to create three completely different presentations.2) If you don’t have anything useful to display for a particular section of your talk, display nothing. During slideshow mode, press B to show a black slide, or W for a white one. Or if you don’t have direct access to the computer while presenting, insert blank slides as necessary. There’s nothing wrong with giving a talk during which you only show one or two slides – but don’t leave them up as wallpaper.3) You don’t have to use any visual aids at all. You might be surprised at how much people focus on you when you stop competing with yourself for attention.

THE CORNELL NOTE-TAKING SYSTEM.

The Cornell system for taking notes is one I have found useful. Note how the page is divided into three large margins. The area for note-taking is where you write your notes during a lecture, class or lesson. Endeavour to take down key points verbatim or in your own words, phrases or style. This will help your learning and encourage a more productive listening. You will aim to capture a good synopsis of what the lesson has attempted to impart. It should include areas you are not clear on and ideas and challenges that come up in your mind. The recall (Cues) column is for recording a measured review of what you have taken down in your notes, and anything that emerges after a lesson. It could include further understanding that has surfaced, and of course further questions. It may include references to supplementary material that could aid understanding. Above all, attempt to have it as a useful exam preparation aid. The summary area is a synopsis of your notes and hopefully will be something that has cemented your understanding of the topic. Visualise your study of a topic as a layered upside-down triangle where as you approach the apex of the triangle your understanding of a topic is more and more concise and fine-tuned, prompted by short and succinct phrases that are the key to a greater and deeper wealth of knowledge that you have acquired. The building of such a structure in itself is an excellent tool in the journey towards greater understanding.
