Oral Pathology India: POWERPOINT ETIQUETTES FOR A GREAT PRESENTATION

Following my earlier post on live presentaions and online appearance it seems natural to tackle another critical and ever-present component of academic and research-related communications. The mighty PowerPoint. It also helped that I came across this compelling video titled "Death By PowerPoint" by @ David PJ Philips. Although our audience usually is much more engaged and forgiving than those in the corporate world, the information being passed on is also meant to have a more significant longterm impact.

Death By Powerpoint

Being from the last generation of teachers whose only visual aid was the chalk & blackboard, I am among those who can fondly recall those good old days where it was so easy to connect with the audience in a typical lecture setting. We could pace our lecture, not loose eye contact for managing the PowerPoint, emphasise, and stay over a topic as long as was necessary, skimp over others or even just leave out some as the situation demanded. I recall an early morning lecture 25 odd years back when in the morning after the annual sports day, I found the majority of the students nearly dozing. I abandoned teaching for 10 minutes or so, chatted with them about the events, woke up everyone with an animated discussion of the games, and then moved back to the topic. This, of course, meant I reorganised the lecture to make up for the 10 minutes. This sort of fluidity is what I miss with the typical PowerPoint presentation.

Not everything was great though, presentations to larger audiences required slide projectors, which had the nasty habit of getting stuck, and the occasional mischance of slides that were upside-down.

Powerpoint brought great freedom to all presentation. All of a sudden we could present data in very legible and attractive fonts rather than handwriting, I am quite sure my students must have celebrated the change. But, with no limits on the type of data, tables, graphs, visuals, related and unrelated pictures, the PowerPoint suddenly moved from being the visual aid for the presentation to being the presentation.

To be truthful, I found matching the quality and engagement of pre-powerpoint era quite challenging whether the aim was just to teach, exchange or disburse information, and most importantly, to inspire greater learning and interest. This made me make a constant effort to improve and update my skills in this field. Through years of study, and learning from more personal mistakes than I would like to recall, I have developed my list of what I like to call Powerpoint Etiquette,

a set of actions that will hopefully produce a visual aid that supports a high impact, easy to understand, informative, and inspiring exchange of information in the least amount of time possible.

There are very handy points in the video:

Have only one message per slide.
Don't repeat the exact contents of the slide
Gain focus on what matters by keeping:

the slide heading or title smaller than the content
use contrast to focus attention on each object on the slide
Use a dark background for the slides to keep the primary focus to yourself rather than the slide

keep the number of objects on each slide limited to six.

Besides those, I find the following useful:

Limit the number of slides: While, it is never a good idea to jam a lot of content into fewer slides as mentioned by @David, an indiscriminate increase of the number of slides is not a good idea either. Presentations in the health sciences are different from the typical show and tell format or the what, where and when of the corporate presentations. We often need to add, the why and the how, which requires description beyond the content of the slide. Slide such as the one below, with few objects is regularly used to introduce and explain broader concepts.

So, depending on how much explanation is necessary for each slide an average of 60-90 slides for a 45-minute lecture is plenty. A lot depends on how fast you can speak while being understandable. While most public speaking advisers consider 120-130 words per minute as acceptable, remember to account for the time needed to change the slides, and pause for important points to make an impression.

Be prepared to abandon the PowerPoint: This is sometimes the hardest thing to do. Often we get so invested in the slides, that we forget they are just a tool in the presentation and not the presentation. So, why abandon the slides we prepared with so much effort? There can be many reasons.

The most common is running out of time. If you have limited time, it is best to abandon the remaining slides and just mention the highlights or list the main topics that were meant to be covered, with an apology and an offer to discuss it further with anyone interested (remember to share your email at the end of the lecture)
Losing the audience: Maybe your's is the first lecture after lunch or the last one in the day, or something diverted everyone's attention, or possibly you misjudged the audience, and they are not as interested in the details. Whatever the reason, it is best to abandon the PowerPoint for a few minutes or entirely. Use the blank screen option, focus your attention totally to the audience, instead of dividing your attention between the audience and the PowerPoint. Make adjustments to the items being described and the number of details, in response to the audience. In general, anything that was text or graph can easily be conveyed by words alone, tables are more tricky if specifics are required. You can return to the PowerPoint once you have the audience's attention again.

Open with a high impact slide: The beginning often decides how the presentation goes. Avoid starting with the typical title slide that can come after you get everyone's attention. Eyecatching art, scenery, or a high-impact slide that relates to your lecture will be a good start too.

End Strong: The best way to end is on a summary message, a few ideas that summarise the talk, or a final message. Thank you, does not need to be a slide and can be just conveyed verbally. However, if the topic has been too vast and the message too extensive to be put in a single slide, end the way you began. An interesting slide, a little bit of humour or something you care about (fight against cancer, wildlife preservation, or whatever matters to you) can make for a great end.
