The Power Of Voting - DAS Ascot 2013

I administered the mobile phone voting system at the DAS Meeting 2013 at Ascot ( and I think all who attended agreed that this type of interactivity added a lot of flavour and stimulation to the discussion of the case presentations.

These are some samples of the results. This first one is from a comparison between the expert panel, comprised of 7 members, and the audience, 140 of whom responded.

Experts & The Audience

This was a case regarding a large wound haematoma secondary to C-spine surgery. The haematoma was anterior to the larynx causing severe narrowing of the airway with stridor. Unfortunately I don't have the CT image from the presentation.

Of the four options (and one "other") the expert panel was split between the two awake options on offer.

The audience, whilst largely agreeing with the experts, gave a wider range of choices with a significant number of people opting for IV induction.

Bear in mind - the audience did not know results of the expert vote prior to voting, all results were only shown after all votes had been cast.

How Lectures Can Change Opinion

An expert on obstetric anaesthesia gave a talk about approaches to GAs in obstetric anaesthesia and the necessity, or not, of RSIs.

Voting was prior to the lecture, with results below.

The same question was asked after the lecture with the following result.

A significant proportion of the audience who voted were swayed by the evidence and experiences presented during the lecture. I found this a particularly interesting utility of easy to use voting systems - gauging the effect of what we teach on the opinions of others.

This was an enjoyable and educational meeting and I must give thanks to Dr Jairaj Rangasami, Dr Mridula Rai, Professor Jaideep Pandit, Dr Subrahmanyan Radhakrishna and Dr Mansukh Popat for having me down for the meeting.

Gamification and Education


Anyone who has used Duolingo for any amount of time will tell you - it's wonderful. Why is it wonderful? Well, it teaches you a foreign language and you can tell its working because you progress. There comes a point where you're typing (or swiping) whole sentences and you just get it. It starts to come together. Suddenly you can say "Our cat does not eat cheese" and then "His trousers are red" in another language. Your pronunciation is probably awful but so what?

The thing with Duolingo is this; it doesn't just teach you, it gamifies the teaching. Each lesson is packaged into little chunks and for each chunk you have 3 hearts, or lives. You can fail but you can't fail too many times. It's a bit like R-Type in that sense, and you can buy power-ups and extras (though I can't find the heart refill anymore, sadly). There's even a timed practice that really puts the pressure on.

So as you can tell, if you've ever thought about th…
