There's video-conferencing...and then there's video-conferencing...

Before I started working at Plan Ceibal, when anyone mentioned video-conferencing, I'd think of Skype. There was that other way of doing it, but I assumed that was for corporate meetings in big businesses.

I did wonder before I started working here why they were installing expensive video conference systems and high speed fibre-optic cables in schools all over Uruguay and insisting on it being installed in Argentina, Mexico, Colombia and the Philippines (where the remote teachers are based). Why didn't they just use Skype or another similar system? I asked myself.

Now, after helping with installation and testing of equipment, observing classes and working here for over three months, it is clear that part of the success of this project is because high definition video-conference equipment is used and not the low quality, low-cost solutions that are fine for most people's domestic use (and sometimes business) use. Having to depend on Skype myself to contact friends and family and to talk to colleagues from Montevideo has also underlined this too.

First of all, for the project to work, it requires the use of equipment that is durable and reliable and an internet connection that is fast and reliable too. That's not to say there are no technical problems - there are, but these are far fewer than there would be if a lower quality less reliable system was used.

Then there's the quality of the image. When I first walked into a classroom with a remote teacher (RT) on the screen, it was almost like she was in the room too. The sharpness of the image means makes it more real for the kids. It also means the RT can see details and even identify the children, which would be impossible using Skype. The lesson plans also require desktop sharing of images, audio and video, which would be problematic, but which works like a dream with the VC system.

It's not just the fibre-optic lines either. For a period of time, while waiting for delivery of VC equipment in the Philippines, the organisation there used a temporary solution (MOVI) and although they were able to cope, there were more technical problems that needed to be dealt with. When the VC equipment was finally set up, the teachers and kids almost jumped for joy at the visible difference in quality.

Playing with Presentations #1

So, my question is, 'What's the best way of displaying a presentation online?' Not only if you want to give people access to your presentation after the event, but also when you are giving the presentation live.

There are now so many different ways of doing this, that it's difficult to choose which one to use.

For example, we used the Elluminate virtual classroom for our live presentation on Gaming & Language Learning last Friday, using Learning Times. But, it might not have been the best way of showing people our slides (see post below). Of course, there are advantages to using this type of platform - the recording is done automatically, and the images are shown at the same time as the audio.

However, you cannot access the recording or attend live unless you are a member (it is free to join, and an easy process, but, even so, it is another barrier), and you cannot simply download the audio only to listen to when on the move (i.e. a podcast)

During the WiAOC, this virtual classroom option seems to be the most popular option, but there have been various alternatives used. For instance, Leigh Blackall's excellent keynote used a Flickr slideshow. The audio was provided by a World Bridges webcast & Skypecast, and it seemed to go very well.

Barbara Dieu (Bee), later today is also going to be using a Worldbridges webcast/Skypecast option, but she's going to use a tool called Zoho Show for her slides. The difference with this is that Barbara can control who sees what because the show is invitation only (by email) and she chooses which slides the participants see at which time from her end. It's a very interesting way of doing it, and I'm looking forward to seeing how it works in practice (I had a trial run with her a few days ago)

Apart from this, there's Bubbleshare and Slideshare too, and I'm sure many other tools (you can provide the slides as a video, with a voiceover).

So, I'm going to upload our presentation to a few different tools to compare them. I want to see how easy it is to upload the files, and look at the quality and feel of the presentation when using them. This will make it easier to decide the next time I have to do a presentation.


Here's the Flickr Slideshow:



Obviously, what's missing from this is an audio recording (I'll add this soon)
