Music lessons for conference organisers

I came across this on aWordPress blog http://returnon.wordpress.com/

I think the speaker makes some good points in his short presentation. Conference organisers everywhere take note!

Turn of that projector!

The best type of learning is active. People learn best by doing, rather than simply listening. Unfortunately too many training course involve sitting and listening to the trainer while watching an endless stream of  poorly designed PowerPoint slides. After a while the audience inevitably starts to lose concentration.

Slides have a role to play in training, but they should be used carefully. They are usually used in a passive way where the trainer talks over the slides. This can be OK for a short while, to introduce concepts or sum up a discussion, but it can get tedious after a while, even if they are well designed.

There are ways of using slides actively. For example by showing pictures on screen which can then be discussed by the class or by using them as the basis of a quiz. But there are plently of other ways of including active elements in a class. For example, brainstorming, exercises, practical demonstrations and role plays.

Introducing variation in courses keeps the audience more involved and interested and breaks up the monotony which can be associated with using one teaching method.

Sometimes it’s a good idea to turn off the projector!

Using Powerpoint in the Classroom

 I spend quite a lot of my time these days teaching and training small groups in a classroom setting. Inevitably this involves making presentations using the default tool – Powerpoint.

As I see it, there are a number of  problems inherent in using  “slideware”, like Powerpoint, in the classroom. These include:

• learning should be active – slideware is passive
• it isn’t good at distributing large amounts of information
• it inhibits spontaneous feedback
• it is not good in conveying information using non-linear paths
• it is not good at recording input from the audience

There are some other problems too. When preparing slides the standard template drives you into producing lists of bullets. This is what Edward Tufte calls the “cognitive style” of Powerpoint. Preparing a presentation using Powerpoint drives you into producing an outline of your talk. The outcome is really a set of speaker notes which is too detailed for the audience.

Faced with slides full of bullets, I find that most people tend to try and reproduce all the points. Their attention  is divided and as they have to concentrate on copying from the slides, so they can’t listen properly to what you’re saying.

Well, they’re the problems I’ve identified, and I’m sure there are others too. What can we do to get over them?

The first thing is to ask yourself whether making a presentation with a stack of slides is the best approach for the class. Active learning, where the learners are engaged, is much more effective than passive techniques where the instructor stands at the front and talks at the class. Consider the alternatives – hands on practicals, exercises, demonstrations, brainstorming, role plays, group work etc. Depending on circumstances it might be viable to incorporate one or more of these into a class. Introducing variation in the teaching methods is always a good idea. To me the best classes are more like a discussion than a lecture.

The second thing to ask is whether having pre-prepared slides is the best visual aid to use. Sometimes its better to revert to the old “chalk and talk” approach using a whiteboard, flip chart or some other active medium. This allows you to be more flexible and draw in and record contributions from the group.

Sometimes there are other options – using models or pieces of equipment you can use for demonstrations, or even pass around.

Where you decide that you need or want to use slideware, there are a number of things you should think about

try and minimise the use of slides. Ask yourself is there another way of getting this across? Use slides only for those points where its really necessary

Remember that slides are free! Break them up. Ideally each slide should focus on one point (although you may want to include some summary slides that pull together the key points, but even then don’t cram too much on one slide – have your summary list on two or more slides if necessary)

Use diagrams and pictures where possible. I’ve attended many presentations where the presenter has slides full of words when a diagram would have been better.  For example, which of the following slides on the structure of the eye would you find most helpful?

Have more slides than you need to cover the main options. This will allow you to be flexible – calling up whichever slide is most appropriate depending on how the discussion progresses. Using Powerpoint’s “presenter view” allows you to do this. Alternatively it may be able to include a menu with hyperlinks into the slide design.

Non-verbal communication

I recently finished reading Ryszard Kapuscinski’s book “Travels with Herodotus”. I particularly liked the following passage:

“Negusi knew only two expressions n English: “problem” and “no problem”. But using this gibberish we communicated ably in the most fraught circumstances. In conjunction with the wordless signals particular to each human being and which can speak volumes f only we would observe him carefully – drink it in, as it were – two words sufficed for us to feel no chasm between us and made traveling together possible”

To me this sums up the role of non-verbal communication. Its possible to understand each other with using words.

This is missing when communication only takes place in writing – as when we use e-mail, carry out electronic conferencing, when conducting “e-learning” and in other situations where we rely on written and verbal communication only. Without face to face contact it is so easy for things to be misunderstood and misinterpreted because the signals given through gestures, body language etc are missing.

Another problem with e-communication is the asynchronous nature of the conversation. Its like playing correspondence chess – there can be long gaps between each “move” and take a long time to complete something which would be over relatively quickly face to face. It is also very easy for the conversation to move off at tangents, which can be difficult to bring back to the original direction.

And it's important to understand the role of non-verbal communication during presentations too. This is one of the key points made by  Susan Weinschenk,  in her video 5 Things Every Presenter Needs To Know About People, which I featured in a previous post, and her book 100 Things Every Presenter Needs to Know About People. In the video Susan's third point is that "what you say is only part of your message" - how it's said (the intonation) and body language - what she calls "para-linguistics" -  are just as important.

The curse of Powerpoint

As soon as you put a slide up on screen with words on it - especially bullet points - your audience starts to frantically copy them down. Try and move on and you get one or more requests to keep it on screen longer. Most people do it - in fact I know that I do it myself when I attend presentations by other people - you almost can't help yourself! As a presenter, if you haven't planned for this, and need to move on, it disrupts your flow.

Why do people do this? I've come up with a few reasons:

• The "Comfort factor" - you feel you are achieving something by writing something down
• There is a perception that if there are words on screen they must be important
• Writing down the points does help you to absorb them, but it also means that you're not listening properly to what the speaker is saying (of course that doesn't matter too much is the speaker is simply reading out the points - but that's another story!!)
• Perhaps it's an ingrained habit from school - i.e. copying off the board.

I think that you have to accept that the audience is going to do this. Its unlikely that you will be able to change their habits. But we need to take it into account when planning the presentation.

When using slides for teaching or training, you want to get over key points that you want the audience to write down so that they can remember them. But the whole point of you being there is that the audience should listen to what you have to say (and when teaching or training you need to interact with your audience), and the words on the screen can distract and prevent them listening to you properly. Slides are meant as an aid to your presentation, not a substitute for it (otherwise you might as well just give them copies of your slides). They need to be used effectively. So taking into account my experience of how an audience reacts to slides, the following should be borne in mind when creating a presentation for teaching and training:

• Only use words that are important on slides - use pictures and graphics to illustrate your points
• When introducing concepts, keep the word count on a slide low - insert more slides with fewer words than a few slides containing lots of words
• Use summary slides with bullet points (but not too many per slide) to sum up concepts which you want your audience to write down, and allow them enough time to for the audience to copy them down

A fresh approach to presentation design

I  recently came across a slide deck posted on Slideshare by Chris Atherton. She’s a psychologist and used to be a Senior Lecturer in Psychology at the University of Central Lancashire. She’s now working as a User Experience Architect for Numiko ltd

The slides are from a presentation Chris made in April at the Leeds Bettakultcha. According to their website this is:

an evening of short talks accompanied by digital slide presentations. The presenters are all volunteers who have based their talk around something that they are passionate about – which can be absolutely anything.

The format of Bettakultcha talks is 20 slides for 15 seconds each (they transition automatically), and you can talk about anything you want. Chris chose to talk about (what else) psychology.

Too many people use Powerpoint in a bad way – either creating an outline or using it as a script. In either case that results in badly designed, over wordy slides. The slides for a “lecture” type presentation should be visual aids to supplement what the presenter is saying, not to reproduce the talk or act as a teleprompter. They should be visual with minimal words that add to what the speaker is saying. Now this means that if the slides are posted onto Slideshare , where the speaker isn’t present, the slide deck can look pretty meaningless. Chris has got over the problem by annotating the slides with a summary of what she said. The annotations on the slides were added afterwards  so that they make sense to the viewer. They weren’t present on the originals. I’ve noticed that a few people have started to do this and it’s a technique that I’ve started to use with presentations I’ve uploaded to Slideshare.

She hasn’t used Powerpoint – she’s tried something quite different. The slides are hand drawn on an iPad using the “Paper”. It’s a, fresh, original approach. You’d have to be reasonably good at drawing to use it, though.

As well as showing a fresh, innovative approach to slide design, I think that this presentation is a really good example  of how to get a technical topic across to a lay audience in a limited time with well designed slides!
